Supporting The Faine House FRSA Staff

The Faine House is an Orlando-based group home for young adults on the verge of homelessness where dozens of Central Florida young adults have lived, opened their first bank account, found employment, attended technical school or earned a college degree. Through The Faine House, young adults have the chance to discover themselves and to see what a future outside the system can hold.

Regardless of their background, every young adult deserves access to dedicated mentorship, quality education and strong emotional support.

The Faine House, co-founded by retired NFL player, businessman and philanthropist Jeff Faine and financial executive and philanthropist Jeff Sharon – two local leaders with a strong spirit and heart for creating change – incorporates their spirit in all that it does. For the past 11 years, The Faine House community, comprised of dedicated volunteers and business leaders,

has empowered young adults in overcoming past challenges and realizing their true potential.

The Faine House operates a 7,000-square-foot facility in the Pine Hills community of Orlando. They host 10 private bedroom suites, accepting 18 to 23-year-olds into the residential program who are in desperate need of access to safety, stability, opportunity and mentorship. Each young adult sets their own financial, occupational and educational goals and participates in a curriculum designed to heal and empower them.

FRSA President Matt Criswell and wife Jackie, chose The Faine House as the 2023 Charity of Choice. In addition to raising funds through the FRSA Convention registration site, Affiliate chapters throughout the state have made donations. Recently, Team FRSA, which included members and staff, participated in a 5k walk and raised over $4,200 for the charity.

FRSA GENERAL COUNSEL Trent Cotney, Partner, Adams and Reese LLP

Updates on OSHA’s Heat Injury and Illness Prevention Efforts Employers know that working in the heat can be a health hazard, especially with summer temperatures already here. Workers in several industries can be affected, so OSHA continues to review and adapt its standards.

On May 19, the Small Business Association’s Office of Advocacy held a Small Business Labor Safety OSHA/MSHA Roundtable. Among the topics discussed was an update on the National Advisory Committee on Occupational Safety and Health (NACOSH) Heat Injury and the Heat Illness Prevention Campaign. The meeting was led by Lisa Long, Deputy Director of OSHA’s Directorate of Standards and Guidance and Pamela Barclay, OSHA health scientist.

Goals of the Work Group

OSHA created the Heat Injury and Illness Prevention Work Group of NACOSH to assist that committee in providing recommendations for heat injury and illness prevention. The first goal (Task One) was to evaluate

OSHA’s heat illness prevention resources and provide input. The second goal (Task Two) was to assess stakeholder input for the Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings advanced notice of proposed rulemaking (ANPRM), then make rule recommendations for OSHA to consider.

Work Group Recommendations for Task One

The group met five times from February 2022 to April 2023 and submitted recommendations for Task One. These included the following:

HURRICANE SEASON IS STORMSEAL SEASON. The world's leading temporary roof protection.

Use Stormseal for: t/ Storm damaged roofs t/ Roofing materials delays t/ Roofing maintenance Become a Stormseal installer before the storm.

Installer training available at Safety Solutions & Supply in Mulberry, Florida.

■ Ensuring that all heat injury and illness documents clearly identify worker rights and employer responsibilities

To raise awareness about heat-related dangers, OSHA is sponsoring a Beat the Heat National Contest.

It has also launched The Heat Source newsletter which ■ Ensuring that all materials and solutions have been can be found on OSHA’s website, www.osha.gov/heat. technically reviewed and are based on evidence ■ Revising any materials with errors or broken links ■ Targeting a wide range of workers ■ Increasing outreach to temporary and youth workers ■ Creating more multi-lingual materials ■ Continuing community outreach efforts related to heat issues ■ Expanding information for healthcare providers, especially first responders ■ Increasing the use of social media and apps for messaging ■ Identifying best practices and technology for employers and workers.

Work Group Recommendations for Task Two The group continues to deliberate on the issues related to Task Two and will provide a written report. This report will include ways to measure and define heat exposure, strategies for reducing work-related heat injury and illness and how existing industry and state standards apply. Task Two recommendations were presented at the NACOSH meeting on May 31.

Heat Illness Prevention Campaign

OSHA launched the Heat Illness Prevention Campaign in 2011 and modeled it after Cal/OSHA’s campaign. Its purpose is to educate both employers and workers about the hazards of working in the heat.

Final Thoughts

It will be interesting to see what results from the Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings ANPRM. In the meantime, if you have concerns about following OSHA guidelines and protecting your workers from the heat, meet with your HR staff to ensure that all policies are current. You can also consult legal counsel.

A seasoned OSHA attorney can assist you in being compliant and advise you on new rule proposals.

Help Save the Rarest Bat in the U.S. Kathryn Slater, Bat Conservation International Homeowners love the distinctive look of Spanish tile roofs, but occasionally, when roofing professionals pull up a few of these barrel tiles, they find an unexpected surprise: Florida bonneted bats. These federally endangered bats sometimes seek cover and protection from predators under the nooks in these tiles. Since they are quiet and unobtrusive, Florida bonneted bats often go unnoticed until tiles are removed during construction. This is why roofing professionals have such an important role in helping save this species – which is the rarest bat in the U.S. – from extinction.

Florida bonneted bats only live in southern Florida and have one of the smallest home ranges of any bat in the U.S. They’re voracious insect eaters and one of the largest bats in North America, with a 20-inch wingspan and skinny wings that make them very fast fliers. Their large, forward-facing ears make them look like they’re wearing a bonnet.

“Florida bonneted bats live from south of Orlando to Miami and it can honestly be said that it’s a Floridian species,” says Dr. Melquisedec Gamba-Rios, Bat Conservation International’s Endangered Species Interventions Research Fellow. “They’re our neighbors and it is a responsibility for all of us to take care of our neighbors.”

Bat Conservation International team and Bob Hilson & Company Inc help to recover Florida bonneted bats at a roofing jobsite.

FLORIDA ROOFING | July 2023

Florida bonneted bats didn’t always live in roofs. Their native habitat includes the Pine Rocklands that once covered large swaths of Miami-Dade County, but only two percent of these forests remain today. Since their natural habitat is almost entirely gone, the bats make do with other spaces, like the nooks in Spanish tile roofs.

“With a lot of species, when their habitat disappears, they disappear,” says Dr. Frank Ridgley, Zoo Conservation and Veterinary Services Manager at Zoo Miami. “But these smart little adaptable bats are figuring out that there are cavities under barrel roof tiles or other kinds of cavities in buildings. But it seems like Spanish tiles are a favorite of theirs and it’s a very popular roofing style down here.”

Words Matter: Roofing-Related Definition Changes Mike Silvers, CPRC, Owner Silvers Systems Inc. and FRSA Director of Technical Services Since we were children, we’ve been told “words matter”. Then we go to school and learn “sticks and stones may break my bones, but words will never hurt me.”

So we were left to wonder which is it? Life very quickly teaches us that the former is definitely true and the latter is…not so much. Words offered with the right motives can lift us up and carry us forward, while negative sentiments from people we care for and respect can very definitely hurt. Words left unsaid may be the most unforgiving of all. You may be asking yourself what does this have to do with codes? Well, after almost 70 of these articles some of this can be chalked up to literary license, while also hoping you can indulge an old man who wants to share a few life observations along the way. I hope the connection to the code will become clearer when we are done.

When dealing with the building code, as with most things in life, words definitely matter. If the words in the building code are to be properly understood, the definitions must play a big part. Terms used in construction do not always perfectly align with those used in our everyday language. Some are not seen in any other context and are specific to a given trade or discipline. We look to the definitions within the code to help us understand the code’s intent. Those definitions are found in several areas. Most are located in Chapter 2 of any given code or subcode. Some that are trade-specific will be contained in their respective chapter as is the case with roofing-specific terms that are included in the Florida Building Code (FBC), Building Chapter 15 Roof Assemblies and Rooftop Structures. Most of the code definitions that impact roofing are shown in the following sections of the code: ■ FBCB (Building) Chapter 2 Definitions and Chapter 15 Roof Assemblies and Rooftop Structures ■ FBCR (Residential) Chapter 2 Definitions ■ FBCEB (Existing Building) Chapter 2 Definitions ■ FBCEC (Energy Conservation) Chapter 2 Definitions The High Velocity Hurricane Zone (HVHZ – MiamiDade and Broward Counties) has its own set of definitions with some minor variations from those shown here. They can be found in: ■ FBCB (Building) Chapter 15, Section 1513 – HighVelocity Hurricane Zone Definitions

14

FLORIDA ROOFING | July 2023

The first group of definitions shown below are some of those that have been added or revised in the FBC 8th Edition (2023). There are others too, but these are the ones that are clearly roofing-related.

After the list of those that have been revised or added, I also provide some definitions that didn’t change but will serve as examples of the types of things included in the code’s definitions sections. Understanding the building code requires an understanding of the definitions. A thorough review is advised. The entire FBC can be found free of charge at floridabuilding.org/c/ default.aspx. Note: Words underscored below are new to the 8th Edition FBC.

FLORIDA ROOFING | July 2023

VAPOR DIFFUSION PORT. An assembly constructed or installed within a roof assembly at an opening in the roof deck to convey water vapor from an unvented attic to the outside atmosphere.

As you can see, there have been extensive changes dealing with gypsum board, panels and sheathing. This should help clarify the many types of gypsum products now offered in the market and how they should be described. For roofing, a few products that would fit the definition of a glass mat gypsum panel would be DensDeck, Securock or other similar products.

The change in the definition of positive drainage will be helpful by changing additional slope to sufficient slope. The term additional slope has been

interpreted to require some type of additional slope be added during reroofing. The old language that stated additional slope has been provided was meant to confirm that the designer of a structure added slope to accommodate deflection of the roof deck to ensure drainage of the roof within 48 hours of precipitation.

The addition of tornados to the Risk Category definition would seem to be concerning, but when you use the ASCE Hazard Tool (asce7hazardtool.online), it will help you understand whether or not tornado loads apply to a particular structure (see page 16). It primarily applies to buildings that have a risk category and a large footprint. The risk category inclusion is understandable, but the footprint portion requires some explanation. In principle, the larger the building the more likely it is to be hit by a tornado. Basically, a large building provides a bigger target for what is (compared to hurricanes) a fairly confined event. For most buildings in Florida, it will not apply.

A definition of roof system has been added, replacing the old definition of roof covering system which said: See roof assembly. The definition of roof assembly includes the deck, which is not typically part of a

roof system and should not have been part of the previously named roof covering system. Roof assembly was tweaked to clarify that some components (vapor barriers, insulation, etc.) may or may not be present in an assembly or system. The diagrams below serve as examples to help clarify these terms.

Wind Uplift Engineering Riku Ylipelkonen, Owner, Standard Building Advisors and FRSA Technical Advisor One of the fundamental concepts in engineering is that context matters. Getting soaked with a garden hose is a fun summer way to cool down.

Using a pressure washer to do the same is dangerous and not recommended. Similarly, wind at 5 miles per hour (MPH) is pleasant, but wind at 105 MPH is not.

Wind behaves predictably as it is scaled. This is useful because we can observe wind behavior at lower speeds and smaller dimensions to model how hurricanes and other wind events affect whatever gets in their path. As shown in Figure 1, the scale model of a building can be built along with the surrounding topography to learn how the wind loads act upon the building.

There are some important estimations shown in Figure 1. First, the fan at the end of Figure 1: Scale Model in Wind Tunnel the tunnel must have a path designed with features to mimic how wind is experienced This kind of wind tunnel testing has also been peron land. The surface roughness bumps help to shape formed on steep-slope roofed building models, much the wind into a proper profile. Next, the turntable like the projects Florida roofing contractors work on has the surrounding buildings assembled to scale every day.

Recent changes to roof zones on hip and because these features affect how the subject buildgable roofs are a prime example of this work. When ing observes the wind. This turntable also spins 360 the modeling shows that the ridge end of a gable degrees or completely around, because the direction rake has a higher-pressure load than the eave end of of the wind event cannot be known. The features and a gable rake, the changes in roof zones take that into shape of the building affect the final wind loads on the account.

This is the same way we learned that the building itself. There are more variables accounted for eave course of a steep-sloped roof covering is more in the testing itself, but these basic facts get the point susceptible to wind loads.

Anyone that has seen the across. The scientific community that publishes ASCE aftermath of a wind event in Florida can attest to that.

The critical feedback of the changes and to predictably identify the shape of this process is the improved ability to collect data the pressure areas so we can apply that to real world from wind events like hurricanes where concepts like roofs.

Pros and Cons of Different Roof Coatings Amir Khan, SVP Research and Development, ICP Building Solutions Group Roof coatings are an important way to protect and maintain roofs in residential and commercial settings.

They are available in a variety of materials, popularly ranging from asphaltic blends to acrylic elastomeric, polyurethane and silicone coatings. Each type offers different advantages and disadvantages for roofing contractors and their clients. This article provides an overview of the various types of roof coatings, along with their individual strengths and weaknesses.

Know Your Roof Coatings

Roofing contractors must naturally consider the type of roof they are working with, the climate of the region and the specific needs of the home or building when choosing a roof coating. Understanding the material composition of the roof, how the environment will affect the coating and the desired performance of the product helps to narrow down the best options.

Roof coatings form a durable and often reflective surface on built-up, modified bitumen and asphalt roofs as well as concrete, metal, wood and many other types of surfaces. Many of these products can be quickly and easily applied using a professional brush, roller or spraying equipment. Contractors should do their own research and consult their peers about the different types of roof coatings and their associated benefits and limitations that are broadly discussed here. One advantage that all coatings have in common is they do not add dead load to existing roof systems because they do not count as additional layers for code purposes, thereby avoiding the cost and complication of tearing off, disposing of and replacing an existing roof. Always be sure to evaluate repair and restoration options before deciding to replace an old roof because coatings offer many benefits, including the opportunity to improve your profits by keeping your crews moving quickly from one job to the next.

Also note that because many roof coatings are rolled or sprayed on, application can require a steady hand and trained eye to avoid filling up any fissures in the roof that might include vents and drainage openings, which can lead to problems like clogs as well as lumps, bumps and other minor imperfections in the finished roof surface. Take time to consult with the coatings manufacturer or other trusted expert if you have any questions concerning proper installation of roof coatings.

Asphaltic Blends

One of the most common types of roof coating, asphalt coatings are manufactured with select asphalt and solvent blends and are popular for their good weathering qualities such as resisting the damaging 30

FLORIDA ROOFING | July 2023

effects of heavy rainfall, large hail, snow or ice accumulation and UV radiation.

These coatings are also preferred for their low-tomoderate cost compared to other types of roof coatings, combined with their fast and easy applicability. These advantages have made asphalt roof coatings the industry-standard choice and backbone of countless successful businesses for decades. Their flexibility is further appreciated by contractors who commonly use them to seal other surfaces like foundations and retaining walls.

Asphalt coatings can be black or aluminized where a reflective and UV-stable coating is needed.

Asphalt roof coatings are susceptible to heat damage and can become brittle with age, so they may not be as effective or long-lasting as other types of coatings when applied to certain substrates. This means asphaltic blends may not be ideal in areas of the country that experience extreme high temperatures or greatly fluctuating hot and cold cycles.

Poorly applied, these coatings can trap moisture and create a breeding ground for mold and mildew, so it is important for crews to have some experience installing them. They also tend to be less reflective than other types of coatings, so owners may not experience the full benefit a “cool roof” can provide in terms of energy savings. Many asphalt coatings contain varying quantities of aluminum flake to make them more reflective; however, average solar reflectance (between 45 to 50 percent) is marginal relative to what is commonly considered a cool roof (80 to 90 percent reflectance).

Asphaltic coatings are generally safe to work with; however, some formulations may emit volatile organic compounds (VOCs), making it important to ensure that the product being specified will comply with all federal, state and local VOC regulations. Warranties

meanwhile may extend anywhere from 5 to 20 years but are generally shorter-lived than the guarantees that come with other types of roof coatings, depending on the type of substrate, system and mileage.

Acrylic Elastomeric Coatings

Sometimes called “rubberized” coatings, these products are generally composed of acrylic polymers that allow them to stretch and move with the structure as temperatures change. Elastomeric roof coatings create a uniform surface that remains flexible even at low temperatures, so the thermal stresses that can tax an asphalt roof are not as much of a concern. Importantly, the chemistry behind acrylic elastomers is as diverse as any roof coatings category, so there are many different options to achieve desired performance and durability. Most acrylic coatings offer outstanding UV protection and, when applied correctly, create a strong watertight seal to withstand nature’s wrath.

These coatings also tend to be bright white, having an 80 to 90 percent solar reflectance that makes them the popular choice for creating cool roofs. A California study found cool roofs stay up to 50-60ºF (28-33ºC) cooler than conventional materials during

however, some products may give off VOCs, making it imperative to read and follow all manufacturer instructions carefully.

Take note that while they are UV-resistant, acrylic coatings can oxidize over time, resulting in loss of mil thickness. Most acrylics will require at least two coats because of their tendency to lose mil thickness over time, meaning potentially more labor time and cost for installers compared to products having higher solids content such as silicone roof coatings discussed later below.

Also important is that, as a water-based product, acrylic elastomers are more susceptible to freezing temperatures at the time of application. Temperatures should be at least 50ºF when the coating is applied because dry time significantly slows down at lower temps.

Warranties for acrylic elastomeric roof coatings typically range from 10 to 20 years though, as discussed, this can vary depending on the type of coating and its desired qualities. Regular cleaning and resealing of the finished roof surface meanwhile will help to maintain its bright appearance and high solar reflectance over the long run.

Polyurethane Coatings

Acrylic elastomeric coatings have been used since the 1970s and are among the easiest for roofing contractors to apply due to their water-based chemistry and cleanup.

peak summer weather and provide an average yearly net savings of almost 50 cents per square foot.

Generally, cool roofs help reduce annual air conditioning use in buildings up to 15 percent according to the U.S. Department of Energy and home and building owners are taking note because the market is expected to grow by approximately $4 billion over the next four years. Roofing contractors who want to take advantage of this trend are wise to consider the latest acrylic elastomeric products for their cool roof projects.

Easy application is another key benefit of acrylic coatings that can mimic the flow and adhesion qualities of household paint, so crews can work quickly and confidently. Cleanup is also simple and fast because these coatings are water solvent.

Costs will vary given the wide range of options available though, in general, acrylic coatings are priced lower than competing silicone and polyurethane formulations. The ingredients used to make them are also safe for the user and environment in most cases; 32

FLORIDA ROOFING | July 2023

Polyurethane coatings form an elastic, watertight film over the roof and offer what is widely considered best-in-class tensile strength, making them among the strongest, most impact-resistant roof coatings available to minimize the damaging effects of cracking, peeling and fading. These highly durable coatings come in two types: aromatic and aliphatic.

Aromatic coatings cost less and are typically used as a base coat because they are not UV stable, meaning they can degrade under sunlight over time.

Yellowing of the roof surface due to dirt pickup can also be a concern. Aliphatic coatings on the other hand provide superior elasticity as well as long-term UV protection. They have good color retention qualities and are typically used as a topcoat. Alone or in combination, these coatings can provide short- or long-term rooftop protection. They also may be used as a base coat for silicone roof coatings.

Polyurethane coatings are a popular choice for creating reflective cool roofs and offer good resistance to

Polyurethane coatings have good mechanical properties and high abrasion resistance that are ideal for where a roof is exposed to heavy foot traffic.

water pooling and UV exposure. Versatility is another key benefit: they have outstanding adhesion qualities and can be easily applied to practically any sloped or flat, textured or smooth roof system. Roofing contractors will further appreciate how polyurethane products can be applied in colder, more variable weather conditions compared to some other types of roof coatings.

Depending on the project, polyurethane coatings may not be the low-cost solution a client is seeking and some products can emit a strong odor that, while not harmful, can be unpleasant for crews and building occupants. These solvent-based coatings can also be hard on professional spraying equipment and require more steps to clean up, which can lead to inconsistent results if the equipment is not maintained properly with the use of cleaning solvents. For instance, if applied too thickly or in poor conditions, pinholes can occur within the film of the coating or air can become trapped as the product cures, which can cause the film to bubble, compromising the overall integrity of the coating. For these reasons, it is important to ensure you hire a certified installer to apply your polyurethane coating properly.

The outstanding durability of polyurethane roof coatings is evidenced by warranties extending up to 25 years for some products. Like acrylic coatings, the ambient temperature should be at least 50ºF when polyurethane coatings are applied.

Silicone Coatings

Silicone roof coatings are most often solvent-based and have high solids content. These roof coatings are applied in a single layer (one or two coats) of silicone-based liquid material in order to form a monolithic membrane. Silicone coatings are extremely durable against weather and are also highly reflective, which can save home and building owners money when air conditioning equipment doesn’t need to work as hard year after year.

Because the product is made using moisture-cured materials, water is no longer absorbed by the coating after it has cured, making silicone coatings more resistant to ponding water situations and eventual breakdown compared to asphaltic and acrylic options.

Additionally, silicone products having high solids content (typically greater than 90 percent) require less coating material during application to achieve the desired dry mil thickness. Applying more coating in a single pass is one way contractors can save time on the job while creating a watertight seal, thanks to multiple thin layers of coating.

Another benefit is that silicones are one of the most environmentally friendly roof coating options because they contain fewer solvents than most moisture-curing products, with some versions being entirely free of solvents. Silicone roof coatings are also highly versatile because they can be applied to most substrates.

The ability to apply silicone coatings at a greater thickness means crews can correct minor slope problems and ponding water situations during the application process.

Potential drawbacks of silicone include: they tend to cost more than other coatings; it can be more difficult to recoat silicone over silicone and roof surfaces coated with silicone can become slippery. Dirt pickup is another factor to be aware of because silicone easily attracts airborne dust that may cause a roof to turn shades of yellow or brown. Frequent cleanings may be necessary to maintain its reflective qualities.

Due particularly to their strong water resistance, silicone roof coatings can carry warranties from 10 to 50 years or what is effectively a lifetime guarantee of the product’s performance in some cases. For projects that are not on a tight budget, silicone roof coatings can provide the added protection and peace of mind that project owners appreciate.

Making the Best Choice

By closely examining your options, you can make an informed decision and find the ideal roof coating for your next coating project. Be sure to carefully consider the pros and cons of each type of coating and evaluate how it will meet your particular needs. Always read labels and research products to ensure that the one you select will protect from the elements and save on energy costs while prolonging the roof’s life span. If you have other questions or would like more details, please contact your chosen products technical department.

The Power of “NO”/KNOW for Roof Coatings Joe Sorrentino, RRO, Florida Regional Manager, Geocel If your firm installs roof coatings beyond the scope of maintenance and repair for low-slope metal commercial roofing, you should read this article. There is a significant change in the acceptance by insurance companies for new spray polyurethane foam (SPF) roof systems and other roof recovers that use the existing roof covering for attachment. This is based on the wind uplift requirements of the Florida Building Code (FBC). After collaboration with several key individuals in the roofing industry, including key individuals in the Florida market, your building owner and manager clients are faced with a tough dilemma.

34

FLORIDA ROOFING | July 2023

The “power of no” is being leveraged by insurance companies for structures when SPF roof systems are used. While doing the research for this article, which I started in January, there have been numerous examples of roof coating installations being denied insurance coverage. This has been confirmed by a representative for a Florida commercial insurance company, an active Florida registered roof consultant, a retired roof consultant (on his multi-family residential roof), as well as multiple roof coating manufacturers.

During a conversation in February with Mike Silvers, FRSA’s Director of Technical Services, we discussed his article, “When is it Too Late for Maintenance or Coating?” (from July 2020 – www.floridaroof.com/frm7-20p29). In that article, Mike identifies that the then applicable 2017 (and current 2020) FBC Existing Building (Chapter 7 – Section 706) clearly states the requirement for use of the existing roof as attachment for a new roof recover must comply with current up-lift requirements. Typically, the use of roof moisture surveys and detailed scope of work is developed to restore an existing roof when utilizing SPF or other new roof recovering. In some cases, the contractor and manufacturer of a roof coating will offer extended labor and material warranties when this process is followed. In one case, an engineering study was developed and submitted to the insurance company for the roof coating installation. It was still rejected by the insurance company. When submitting a proposal for this type of assembly, a wind uplift test is often not performed. If the existing low-slope commercial roof has been in place between 7 to 15 years, the possibility of the existing roof being code-compliant is slim to none. Although the state legislature has passed several laws in response to Florida’s tumultuous insurance market, including Senate Bill 2-D in May 2022, Senate Bill 2-A in December 2022 and most recently Senate Bill 7052, House Bill 881 and

House Bill 799 on June 1, 2023, these new laws remain primarily focused on residential roof claims, new hurricane mitigation programs for qualifying homeowners and curbing rising premiums for residential property insurance lines. According to Trent Cotney, Adams and Reese LLP and FRSA’s General Counsel, “While the new laws passed in Florida do provide additional accountability and oversight on the manner in which insurance companies generally handle claims, they provide little to no guidance on such nuanced commercial roof repairs or coating applications that commercial and multi-family property owners often assume and expect would be covered under their applicable insurance policies. It is imperative that both roofing contractors and commercial owners are apprised of potential coverage issues and scope of work considerations, concerning contemplated repairs to low-slope commercial and multi-family roofs, while we await necessary future legislation to more aptly address the commercial insurance sector,” says Cotney.

Although the state passed Bill 2-D in May 2022, this does not include commercial properties. According to Cotney, the bill is dedicated to residential construction and protection for homeowners. “I do not see any protection of re-insurance of low-slope commercial or multi-family construction in the bill.”

For decades, roof coating manufacturers have offered protective roof coating products, extending

the useful service life of a roof system. Several roof coating manufacturers have offered contractors and building owners labor and material warranties that have been in existence since the mid-1980’s. These are like those offered by low-slope commercial roofing manufacturers after the roof bond era. In addition to warranties of 10, 15 or 20 years, roof coating manufacturers have offered renewable warranty terms beyond the initial warranty. These renewable warranty programs created a sustainability concept that many roofing contractors and building owners have embraced. This restoration paradigm is challenged by the decisions being made at present by the insurance carriers in the state of Florida. We have a “perfect storm” combining the current state of the insurance industry and the Florida Building Code wind uplift requirements. Since the attachment of the existing roofing assembly is what holds a new SPF covering in place, the power of “no” – as in no coverage – by insurance firms is a legitimate concern.

It is important to differentiate between maintenance and repair as opposed to a code compliant roof system when proposing roof coatings or roof recovers to a building owner. As Mike Silvers stated during FRSA’s April Codes Committee meeting, “When it comes to wind uplift resistance requirements, there is no difference between new roof systems and roof recovers.”

There is a legitimate concern for any contractor proposing this type of roofing alternative to a building owner, property manager or design firm that is unaware of the potential issues with insurance coverage.

Although we know there are liquid-applied (fluid-applied) roofing assemblies that are Factory Mutual (FM) and Underwriter Laboratories (UL) approved assemblies, that does not stop an insurance carrier from denying coverage to this type of installation on your client’s structure. It is important to be transparent prior to submitting a proposal or intent to perform work. If you do not share this potential issue with your client, it can become a tragedy for them and your firm. The power of “no” is much more powerful than yes.

If it was not for a Florida roofing industry professional raising his concern, this article would not have been written. Thank you – you know who you are.

Forklift Safety Jorge Castanon, Safety Consultant, FRSA Self Insurer’s Fund Having a forklift at your workplace to help lift, move, stack and store raw materials or finished product helps get the job done efficiently. Powered industrial trucks or forklifts are the workhorses often used to get these jobs done and, as with any piece of equipment being used on the job, safe operating procedures are a must.

A forklift operated by an inexperienced or poorly trained employee can lead to accidents, injuries or even death. The Occupational Safety and Health Administration (OSHA) requires that all forklift operators be certified in forklift safety. The OSHA forklift certification requirements are: ■ Operators must be at least 18 years old.

■ New operators must complete forklift training and become officially certified.

■ Certifications must be updated every three years.

■ Forklift operators must carry proof of their certification.

Having untrained operators can create hazards.

Falling loads caused by overloading, unbalanced loads, improper loading, loads stacked too high obstructing the operator’s view, forklifts operating too fast and

improper maintenance may cause unwanted harm to workers. Operators are not only responsible for themselves, the cargo and the forklift but also responsible for everyone around them. The following guidelines will help maintain a safe workplace for yourself and your coworkers: ■ Before operating any forklift, you must become familiar with the location and function of the controls and other general operating functions.

■ A pre-operation inspection must be done before using a forklift.

■ It is important to recognize that operating a forklift is very different than operating a car. While the forklift is probably smaller than your car, it can be up to two-to-three times heavier. Because of the weight of a forklift, it is not as easy as stopping a car, so give yourself plenty of time to react by driving slowly.

■ You should always read the operator’s manual before operating a forklift. Do not forget to read the warning labels, nameplate data, load capacity and other important safety reminders.

■ If the forklift has a seat belt, wear it in case of a tip over. The seat belt will keep you within the protective framework of the unit. If you try to jump off during your tip over, you could be thrown under the forklift or the load, which can lead to injury or even death.

■ Always raise the height of the forks about two to four inches above the ground while traveling and keep the load at the lowest safe height.

■ Always drive at slow speed.

■ Visibility is restricted while carrying a load and you will encounter blind spots. Always check to make sure no one is in your path before moving.

■ Pedestrians always have the right of way. Sound the horn at intersections and proceed slowly.

■ Keep three truck lengths between forklifts and never pass another forklift.

■ When lifting, make sure the load does not exceed the capacity of the forklift. The capacity is listed on the identification plate and in the operator’s manual.

If you are using a forklift outdoors or at a construction site, you are bound to encounter rough, uneven terrain. Pneumatic tires are used on these forklifts because they are more forgiving, making the unit easier to handle. This helps increase safety and stability.

Forklifts are our industries’ workhorses, moving, storing, stacking and loading everything from raw materials to finished product. As a forklift operator, you must always keep one goal in mind: the safety and efficient operation of your unit.

COTNEY CONSULTING GROUP John Kenney, CPRC, CEO, Cotney Consulting Group

Project Management and Cash Flow Managing roofing projects involves various tools and techniques to oversee them. Many tools have changed with the advances in methods and technologies. Cash, however, is the one constant tool that contractors will continue to rely on. While cash is not necessarily actual dollar bills and coins, a positive flow of money into the bank is essential to the financial health of contractors. The lack of cash flow is likely the most common reason for contractor failures. Contractors who report profits and have a good reputation for quality work may still have financial difficulties if they are not paid on time and do not have a positive cash flow.

Each roofing job is seen as an individual revenue base and contractors rely on roofing projects to bring in cash in the form of monthly payments from clients.

Cash flow should not be just the focus of your CFO or Controller: it should be a priority and the primary focus of everyone from the owner down to the project team.

The concept of cash flow has several elements, most of them included in the broad concept of cash outflow and cash inflow. Jobsite expenditures, including labor, material, equipment, subcontractors and indirect costs, have a negative impact on cash flow and require tracking. The only significant positive cash flow is revenue received from the client. Contractors always want to operate in the black; that is, to make their cash inflow greater than their outflow. There are various methods a contractor can use to improve their cash position, some of which we will discuss in this article.

Preparing a cash flow curve for a roofing project is vital to managing costs and ensuring positive cash flow. The cash flow curve is a projection of the total value of work to be completed each month during the project’s construction. The curve is created by cost-loading the schedule and plotting total monthly expenditures.

To create the cash flow curve, the estimator or project manager must develop a cost-loaded schedule, starting with a summary schedule and estimate. The activities on both schedules should be similar and not be overly detailed for clarity and ease of use.

Construction-specific accounting software should make preparing a cash flow by job report easy, if not automatic. Some systems even incorporate this report into their executive dashboards, so the information is displayed graphically and available in real-time.

Tracking Job Costs

Tracking job costs is one of the most time-consuming but essential aspects of cost control for a roofing project. Direct labor costs are tracked by filling out 50

FLORIDA ROOFING | July 2023

time sheets for the crew, which report hours worked against a description of work activities and cost codes assigned to those activities. Direct material costs are tracked by recording material deliveries and matching them with supplier invoices, with the appropriate cost code assigned to those materials.

Subcontractor invoices are submitted to the roofing contractor and logged as accounts payable before being forwarded to the project manager for approval. Your accounting team should verify that the total amount billed does not exceed the amount approved in each contract and assign the appropriate cost code for each subcontractor. The project manager or superintendent should verify the percentage completed for each subcontractor request.

The cost of jobsite general conditions includes indirect expenses such as equipment rental and labor costs not directly associated with job-specific costs.

Indirect labor expenses include salaries for personnel such as superintendents, project managers and other supervisory personnel.

Salaried personnel, including the project manager, superintendent and other supervisory personnel, may not be required to complete time sheets like crew leaders do for their crews. If your company tracks these to projects rather than general overhead, they are individually assigned to a different cost code within the project’s general conditions estimate. The company routinely records a portion of its monthly salary against its individual cost code, which is incorporated into the labor and job cost history reports.

There is only one source of positive cash influx for a roofing contractor: receipt of payment from the client.

This usually occurs once a month, after the work has been done. Residential contractors and some commercial contractors on private reroofing projects often receive a check at the time of sale or mobilization of the project.

The CFO or Controller is responsible for processing cash flow to make payments on all jobsite expenditures and receiving monthly client payments. The company relies on positive cash flow when revenues exceed expenses. The CFO or Controller may have an established line of credit with their bank and may call

on those funds in case of a short-term cash shortfall but pays them back as soon as possible. Still, your goal should be to finance your projects from a solid cash flow position that keeps additional cash for times when you may need to cover expenditures. The contractor usually pays direct and sub-labor weekly and does not withhold retention from the worker’s checks.

Revenues typically lag expenditures early in the project when an increased amount of direct labor and material is expended to mobilize and start the project.

Later in the project, cash flow needs are eased during the punch-out and close-out phases.

The lack of positive cash flow is one of the most common reasons for contractor bankruptcy. Contractors continually relying on the bank to fund their operations will fail. Negotiate terms with clients and subcontractors to improve cash flow, prepare timely, accurate and fair pay requests and obtain financing.

Below are some methods you can incorporate for cash flow improvement within your company: ■ As a subcontractor, you finance the general contractor in that you are not paid until the client pays the general contractor and retention is withheld from your payment; the same as what the client withholds from the general contractor. You can significantly improve your cash flow position by incorporating a lower mix of general contracting work and more privately negotiated reroof projects.

amount of front-loading of the schedule of values, just not an excessive amount.

In conclusion, cash flow management is crucial to the success of any roofing project. The lack of positive cash flow can lead to financial difficulties and even contractor failures. It is essential to track job costs and prepare a cash flow curve for each project to manage costs effectively and ensure positive cash flow. By incorporating these methods and prioritizing cash flow management, roofing contractors can maintain financial health and achieve success in their projects and business.

■ Include a mobilization charge in the schedule of values; this should be standard practice.

■ Require the client to make a down payment or invoice the client twice monthly. You must negotiate this into your contract, but the answer will always be no unless you ask.

■ Negotiate retention withheld from 10 to 5 percent.

■ Request retention released on portions of the work completed and accepted. This is also done during contract negotiation.

■ Have a solid estimating practice in place. By doing so, you will beat the budget or have significantly fewer overruns and performed work will cost less, considerably improving the cash flow position.

The Veterans got a garage tour of the No. 14 AJ Foyt Racing Chevrolet driven by Santino Ferrucci, walked the fabled Yard of Bricks and got a front-row seat to the patriotic, starsand-stripes-clad HFOT Indy car racing to a thrilling third-place finish.

“The events at the Indy 500 were an incredible experience for our Veterans, including one-on-one interactions with the AJ Foyt Racing team as well as celebrating driver Santino Ferrucci’s third-place finish.

We are so grateful to ABC Supply for not only hosting HFOT at the event but for raising national awareness of our mission of ‘Building Homes and Rebuilding Lives’ through both the car’s patriotic design and by matching donations throughout the month of May. Our Veterans had the experience of a lifetime and the exposure we gained ensures we can build and donate specially adapted custom homes to many more of our nation’s most severely injured post-9/11 Veterans,” says HFOT President and CEO Brigadier General, USA (Ret) Tom Landwermeyer.

ABC Supply has been a passionate supporter of HFOT since 2020 and donated the design of the Indy car to create more awareness for the organization, 52

Veterans, enabling them to rebuild their lives. HFOT has built 355 specially adapted homes since its inception in 2004.

“We were excited to host this monthlong donation match campaign and now, we’re simply humbled by the overwhelming support that has poured in for HFOT,” says Mike Jost, Chief Operating Officer at ABC Supply. “Our relationship with HFOT means a great deal to us and we’re so thankful to the team at AJ Foyt Racing for helping us bring light to the incredible work the organization does for our nation’s Veterans.”

“The entire AJ Foyt Racing team has been honored to represent such a wonderful organization,” said Team President Larry Foyt. “From meeting some courageous heroes who attended the race to carrying the beautiful red, white and blue livery on Memorial Day weekend, this program has been special to our team and fans alike. We’re thrilled that we could have a fantastic finish and hopefully raise a great deal of awareness about Homes for Our Troops.”

Rick Jenkins, President & CEO, Quality Roofing, Inc. How did you get started in the roofing industry?

My father, Harrison, made me! He had a family roofing business and I was trained by my father to install the best roofing systems, to the best of our ability. I then tried a few other trades, but roofing is in my blood. I’ve been in business for 29 years.

What’s your favorite part of the job?

Designing and specifying jobs and negotiating contracts with customers. I like to give my customers the best product and value for their project.

What’s the most unusual roofing project that you’ve been a part of?

There have been two. The first was the Crystal River Nuclear Plant. This was the first fluid-applied roofing system that I installed when I was younger. Being at that facility and standing under the shadow of the nuclear reactors was incredibly intimidating. I couldn’t help but feel like I would disintegrate at any moment. The second was the Wish Farms Treehouse. This is another project I am extremely proud of. The premise of the treehouse roof design was undulated, so it looked like a kid drew it in Pre-K. The original spec for the project was to install a copper standing seam roof, which wouldn’t have worked.

As a team, we decided to custom cut and fabricate individual copper shingles and it came out beautiful. It was featured on the December 2021 cover of FRM. What would you do for a career if you weren’t doing this?

I originally thought I may want to be a pharmacist, but I realized that if I wasn’t a roofer I would starve. Joking aside, some type of sales or marketing for a company or product that I would be proud of. I prefer to sell things that I believe in.

How do you define success?

Honesty, quality of workmanship and integrity. I also play well with others. Having a friend and partner in business like John Garrison, Vice-President of Quality Roofing, Inc., has contributed to my individual success as well as the success of the company.

What inspired you to join FRSA? I have been a member of the FRSA for a long time. The main reason I have stayed with the FRSA is because of

Morris Swope. In my opinion, he turned the FRSA into what it is today: a true benefit for the roofer! FRSA is also extremely beneficial for instigating continuing education, providing financial support and ensuring jobsite safety.

What advice would you give to someone interested in joining the roofing industry?

1) Be honest, work hard and strive to install the best quality roofing systems available to you. Master what you are good at and stick to it. 2) Find mentors and rely on them for advice and guidance. My mentors have been my dad James H. Jenkins, Sr., Morris Swope, Salvatore (Big Sam) Ferlita, as well as suppliers and partners like Jim Resch, Jim Coston, Les Thompson and Eric McKenzie.

What do you consider a waste of time?

Dealing with clients that don’t want a proper roofing system for their building; the ones whose motivation is price and not a quality product. It goes against my goal of providing a quality product, every time.

What’s your favorite vacation?

Spending time with my wife, wherever that destination is.

Especially when we spent time in the New England area watching our son play college football and had our kids, grandkids and other family members join us.

What’s your favorite pastime activity?

Going out on my boat, hunting and snow skiing. I also enjoy, like many of my fellow roofers, drinking and partying, but not golfing.

Where would be your ideal place to live and why?

Right here in Tampa, Florida. I love it here! Especially in the house that I designed, built and plan to die in – but hopefully not today!

What would surprise others to learn about you?

Basically, I am a bionic man, but not in a good way. When I was four weeks old, I had to have a left lung lobe removal.

At that time, it was the second successful surgery of this type in the U.S. I was lucky and now it’s performed arthroscopically. Since then, I’ve also had a hip replacement, ankle graph and asphalt burns. As you can imagine, I have a lot of scars.
