FRSA LEGAL COUNSEL Cotney Attorneys & Consultants

Material Shortages and the Implied Warranty of Availability of Materials Trent Cotney, CEO, Cotney Attorneys & Consultants You may be familiar with the implied warranty of constructability. Under this legal doctrine, if you comply with the owner-supplied plans and specifications on a public project, you have an argument that you are not responsible for any loss or damage due to defective or insufficient plans. However, there is also limited support for what is known as the implied warranty of availability.

COVID-19 has caused a variety of material shortages and price increases affecting lumber, steel and shingles. Recently, FRSA affiliate, RCASF issued a notice that foam used for tile installation was in short supply, delaying projects. As a result of these material shortages, contractors have had to adjust to delays and determine how to keep the customer happy despite the inability to obtain key materials needed for construction.

Material Specifications

In most cases, preferred materials are readily available for construction projects. However, there could be a project where an owner requires the use of a construction material that is difficult to locate or is available only from a single supplier. In this case, it could be reasonable to conclude that the owner implicitly warrants the specified material’s availability.

Under the implied warranty of availability, if an owner specifies a material available only from one supplier or requests one supplier for a specialty or brand name material and that supplier cannot or will not provide the required material, then the owner’s specifications are defective. In this instance, it follows that the owner has broken the implied warranty of constructability and is therefore liable for any damages or expenses that the contractor encounters.

Constructability vs. Availability

Although the implied warranty of constructability and the implied warranty of availability are connected, there is a difference. The constructability warranty focuses on the accuracy of the plans and specifications, while the availability warranty concerns the commercial availability of specified materials. Per the implied warranty of availability, the owner warrants that the selected supplier can provide a specified construction material.

The issue is further complicated by timeframe and price. Case law has narrowed the parameters of

the implied warranty of availability in this way: although the owner warrants commercial availability, the owner does not warrant that the supplier can provide the material for a specific price or in a timely fashion.

In addition, this implied warranty pertains only to owner-selected suppliers or construction materials, not to materials or supplier selections that the contractor makes. If a contractor recommends using a specialty or brand-name material from a single supplier, the contractor is solely and entirely responsible for securing the material.

Therefore, the contractor is liable for damages if the material is unavailable for the construction project.

Implied Warranty Case Law

The implied warranty of constructability was up for debate in two notable cases: US v. Spearin, 248 US 132 (1918) and Phillips Jordan v. State of Florida Department of Transportation, 602 So.2d 1310 (Fla. 1st DCA 1992).

In the first case, a utility contractor named Spearin was under contract with the United States to build a dry dock for the Brooklyn Navy Yard and relocate a six-foot storm sewer at the site. The US government provided the plans and specifications, including the materials, dimensions and new location for the sewer.

When the sewer later failed, it was discovered that the city plans were inaccurate, but the government claimed that Spearin was at fault and therefore responsible for repairing the sewer. Spearin stated that the government should change the sewer design and make the repairs or pay him to fix it. The government refused those terms, terminated the contract, revised the sewer design and hired another contractor to complete the job.

Spearin then sued the US government, claiming wrongful termination and seeking money owed for the work he had performed, along with profits for the unperformed work. The Court of Claims ruled in Spearin’s favor. The case was appealed and then heard www.floridaroof.com | FLORIDA ROOFING

by the US Supreme Court, which upheld the decision and created the Spearin Doctrine. The Supreme Court stated that a contractor is obligated to complete a project according to the specifications that the owner provides and is not liable for problems resulting from inaccurate plans.

In contrast, in the second case, Phillips and Jordan were hired by the Florida Department of Transportation (DOT) to build a fence along I-75 In Brevard County. After the project was completed, Phillips and Jordan requested additional payment since they had to clear and grub more land than specified in the contract. The DOT refused and Phillips and Jordan filed suit.

The court ruled for the DOT, stating that the implied warranty of construction did not apply in this case, as Phillips and Jordan inspected the land in question before bidding on the project and should have been aware of the area and equipment requirements.

As for the implied warranty of availability, the seminal case is Aerodex, Inc. v. United States, 189 Ct. Cl. 344, 417, F.2d 1361 (1969). In that case, Aerodex won a bid to provide missile systems for the government. Per the bid proposal and contract documents, the contractor was required to obtain a brand-name version of a missile system component from a specific supplier. However, the component supplier refused to sell the part to the contractor. The court ruled in favor of Aerodex, stating that the government was responsible for assuring that the component was available or allowing the bidders to make a component duplication. The government breached the implied warranty

of availability, so it was liable for the contractor’s damages.

It is worth noting that the implied warranties identified herein are primarily used on public projects as evidenced by the cases above. However, it may be possible to make similar arguments using different theories on private projects.

Understanding Your Responsibilities

Before you bid on any construction project, make sure that you carefully read the material specifications and understand your related responsibility. If you have questions about a preferred brand or supplier, raise those issues before accepting a contract.

We anticipate that price increases and material shortages will continue throughout 2021. Accounting for those issues contractually as well as maintaining an open line of communication with your suppliers is essential to avoid unnecessary delays or unexpected material price inflation.

New ASTM Standard Replaces Felt Standards for Qualification of Synthetic Underlayments Greg Keeler, Technical Service Leader, Owens Corning Synthetic underlayments have been available for over 20 years and very early versions left a bad impression on some contractors. However, things have now changed for the better.

development – until now.

Why Synthetic Underlayment?

Early synthetic underlayments were tested and qualified for use under ASTM Standards that were intended to be applied to asphalt-impregnated felt underlayments. For many years, the International Codes (IBC and IRC) and the Florida Building Code have referenced ASTM D226, ASTM D4869 and ASTM D6757 – all standards that were intended to apply to asphaltic felt underlayments. The problem with that approach was that those standards are primarily composition driven.

Since they were intended to be applied to asphaltic underlayments, there is very little testing that can be performed on synthetic underlayments. In fact, when a synthetic underlayment is tested under ASTM D226, for instance, the only tests that can be applied are the Unrolling, Breaking Strength and Pliability tests.

Those that have installed underlayment know that those three tests alone demonstrate very little about a product’s suitability.

It didn’t take too long for the roofing industry to recognize the unsuitability of the existing felt standards for assessing synthetic underlayments. As a result, several synthetic underlayment manufacturers worked with the International Code Council Evaluation Service (ICC-ES) to develop Acceptance Criteria for synthetic underlayments. Acceptance Criteria are similar to ASTM Standards, with a couple of distinct differences:

Roofing contractors are always looking for ways to do their job more efficiently and to provide product choices that they feel improve the quality and durability of the installed roof. Asphalt felt underlayments, also referred to as “felt paper” or “tar paper,” have served the roofing industry well for decades. However, there have always been shortcomings with these products.

As the monikers indicate, the most prevalent drawback of these products is that they are essentially paper saturated with asphalt. The organic paper core of these products is sensitive to changes in humidity and tears easily. Because the paper core isn’t 100 percent saturated, the paper can still absorb moisture, which can cause waviness when installed on the roof.

Generally, the heavier the paper core, the more waviness potential. The other major drawback of these products is their propensity to tear easily. Tearing is a concern especially where it occurs around fasteners when the product is enduring foot traffic during roof covering installation. Tearing is also a major concern when it comes to the ability of the underlayment to remain in place during a high wind event, especially if the primary roof covering has blown off.

The above concerns were the primary drivers for the development of synthetic underlayments.

Synthetic underlayments are designed to provide superior strength: resistance against both tensile (pulling) and tearing. However, the test standards for these products just hadn’t caught up to product

The History of Synthetic Underlayment Testing

■ They are not consensus-based standards; the test requirements and conditions of acceptance are determined by the manufacturer and ICC-ES with very limited input from industry stakeholders.

■ The Acceptance Criteria cannot be referenced in the I-Codes as a Reference Standard.

Acceptance Criteria are deemed to be an alternative compliance path that applies to products for which the codes do not include prescriptive 12

FLORIDA ROOFING | April 2021

requirements. Additionally, they are limited to use exclusively for the purposes of obtaining an ICC-ES Evaluation Report. The two applicable Acceptance Criteria are: ■ AC 188 – Acceptance Criteria for Roof Underlayments ■ AC 207 – Acceptance Criteria for Polypropylene Roof Underlayments (limited to spun bond polypropylene underlayments)

Industry and Increased Synthetic Underlayment Presence Prompted Development of an ASTM Standard

After years of increasing numbers of synthetic underlayment products being introduced into the market, without a defined process for qualifying the underlayments, the roofing industry decided that it was finally time to develop a consensus standard for these products.

Over approximately an eight-year period, members of an ASTM Task Group worked to develop a standard that establishes appropriate and stringent

performance requirements for synthetic underlayments. Task group members represent contractors, roof consultants, product manufacturers, test labs, test equipment manufacturers and more. This diverse membership lends credibility to the process and the resulting standard.

The result of this hard work is ASTM D8257 – Standard Specification for Mechanically Attached Polymeric Roof Underlayment Used in Steep Slope Roofing. This standard establishes a high bar for synthetic underlayment performance and durability.

It includes many test requirements that are unprecedented for underlayment standards. These tests include fastener pull-through, UV resistance and hydrostatic resistance among others.

To illustrate the benefits of synthetic products that are tested and approved in accordance with ASTM D8257, below is a table that compares the differences between the various felt-based ASTM Standards, the ICC-ES Acceptance Criteria and the new ASTM D8257 Standard.

Use of Polyurethane Adhesives and Insulation in the Roofing Industry Riku Ylipelkonen, Technical Service Manager, Polyset Roofing Adhesives, ICP Building Solutions Group

Otto Bayer is credited with developing polyurethane in 1937. Original development applications were related to aircraft coatings for World War II and flexible foams. Commercial applications began later in 1952 and grew steadily as polyurethane foams became a viable choice for rigid foam buns and molding parts where the reaction occurred in the mold for the finished part. The advantages of polyurethane foam (PUF) helped grow many applications and uses. High heat resistance and long-term stability due to the polymer being a thermoset plastic led to the development of PUF adhesives in roofing applications.

Polyurethane is a reaction polymer, where isocyanates react with polyols and result in a thermosetting polymer. The main feature of thermosetting polymers is that they do not melt or breakdown with the application of heat. For example, when eggs and flour are combined and cooked, a pancake is made. The pancake cannot be returned to eggs and flour by heating it up. The opposite of thermoset polymers is thermoplastic polymers. Thermoplastic polymers will return to their original state if heated. As an example of this, an ice cube will become water if it is heated. However, if the water is returned to a freezer, it will become an ice cube again.

The other benefit of thermosetting polymers is the long-term stability of the polymer. However, the stability of polyurethane polymers is mainly susceptible to exposure of ultraviolet (UV) light. When PUF is exposed to sunlight, which contains UV light, there is a yellowing discoloration that occurs over time. The higher energy of UV light can also cause reactions that break-up the PUF and flake the exposed foam off as exposure time is prolonged.

Prevalent uses of PUF in the roofing industry have slowly grown over the years. The applications that 14

FLORIDA ROOFING | April 2021

are specified have used different polyurethane formulations which vary based on the raw materials used. Sprayed polyurethane foam (SPF) roofs are popular and substantial low slope roof applications that use the physical properties of polyurethane more as an insulation than an adhesive.

Raw materials are varied to result in a high closed-cell content that create excellent insulation properties.

The use of spray equipment, where the reaction is controlled on the rooftop, helps to minimize preparation process to the job site.

The top coating is used to minimize sunlight and UV light exposure, to maintain the physical properties and waterproofing qualities of the finished roof.

A growing application for SPF is as an adhesive for roofing materials. On low slope roofing, these adhesives are used to adhere common building materials to make the final roof assembly. On steep slope roofing, SPF adhesives are used for adhering clay and concrete roof tiles. SPF can be advantageous for several reasons. There is no need for high temperature materials like hot asphalt that cost money to heat and transport to the installation site safely (crew safety, property destruction and insurance considerations).

SPFs are usually low in volatile organic compounds (VOC), reducing site complaints of fumes during application, environmental considerations for the project and simpler, less costly personal protective equipment (PPE) for installers. SPF adhesives can also minimize

or eliminate the need for mechanical fasteners and roof penetrations, to reduce the likelihood of leaks, energy loss through heat conduction of metal fasteners and the amount of labor required to install materials.

For roofing applications, the PUF options fall into two main categories, one-component (1K, moisture-cured) and two-component (2K, chemical-cured) systems. The advantages of 1K systems are usually ease of use, cost and easier to have multiple systems being used on the roof at the same time. To take full advantage of a 1K product, the isocyanates and polyols are packaged into the same cylinder under pressure and come out of the dispensing equipment as a properly ratioed foam ready to be applied to the materials to be adhered. This eliminates the ratio calibration checks and periodic checks for properly curing foam that most manufacturers require with a 2K product. This allows for simpler operation of the product dispensing system and less packaging than a comparable 2K product. 1K products are usually produced in smaller packaging to allow multiple kits to be used at the same time on a roof with a larger number of qualified applicators in order to get more squares done per day. The tradeoffs for 1K products include that they require ambient moisture to facilitate the curing of the foam, lower values of physical properties than 2K gram per gram and the need for the 1K PUF to be compressed into final place for developing a compatible bond with substrates. 1K will need to be compressed between tile-to-tile applications and cover board-to-insulation layer applications to bite and form a bond to whatever substrate the product is applied. The 1K products also cure from the outside in, which limits how much adhesive can be applied to one location while having the ability for the foam paddy or bead to completely cure to designed physical properties characteristics. The last consideration for 1K components is the limitation of ambient and substrate temperatures. Because the 1K needs moisture and compression to cure, it favors warmer and more humid ambient conditions to facilitate a complete cure.

Two-component systems are favorable when physical properties (like tensile strength) need to be maximized, wider temperature ranges for ambient and substrate temperatures are required and for larger size jobs requiring faster application rates, larger

containers of product and more uniform physical property characteristics in the final product without the presence of ambient moisture. 2K products can be fine-tuned to cure quicker, grow more during application and have a specific set of physical properties for the desired application. 2K products are better at expansion to a final size to ensure good contact area under roof tile applications and to account for deck undulations when laying insulation or cover board on an existing roof deck. Since the formulations of 2K products have catalysts in the formula to ensure proper and desired cure, ambient moisture is not a concern and a wider range of ambient and substrate temperatures can be utilized. This also ensures that the 2K products cure from the inside out, so large volumes and increased open times can be taken advantage of if the application benefits from it. This also helps the 2K products to be more uniform in final cured form, possess better cell structure in the body of the foam paddy or bead and they don’t need applied compression to form bonds with the substrate.

The trade-off for 2K products also should be considered. Qualified applicators need to make sure the dispensing equipment is set-up properly to prevent crossovers from kit to kit, dispensing equipment must be kept clean, flowing and purged at wait times to prevent any clogs or cured foam within the lines. This could ruin the entire kit if disposable pre-pressurized kits are being used. Depending on the dispensing system, ratio calibration and periodic ratio checks are also required to maintain quality of the job and to catch changing variables like temperature and pressures of the separate components. Also, the chemical must be kept within the recommended temperature range; cold jobsites could ruin productivity if the product is too cold to use. However, if the 2K products are properly set-up, dispensed and applied, the final product will be stronger, faster to apply and more profitable for the roofing contractor.

Product offerings for polyurethane adhesives and insulation are growing constantly in the roofing industry. The list of companies that are offering these products is growing as well. When looking at the options for products and companies, there are benefits to looking out for companies that have knowledge of the roofing applications, have local personnel to support the contractors on the jobsites and provide Continued on page 41

Training, Codes, Legislation and Research are on FRSA’s Horizon Mike Silvers, CPRC, Owner of Silvers Systems Inc. and FRSA Technical Director Like many of you, I was thrilled to see that the next FRSA Board of Directors meeting in April will be an in-person event. For many of us this is another step in the all-too-slow return to somewhat normal.

Virtual meetings have allowed our work to continue but are lacking in the face-to-face exchanges of information and viewpoints that in-person meetings offer. These meetings and the Convention have been the life blood of our Association.

A few days before this writing I received my COVID vaccination. I was among the last in my age group to receive it but was very happy and somewhat relieved to get it. I guess there are a few advantages of being an old guy – I’m not complaining about getting older mind you – I certainly prefer it to the alternative.

Beginning to put the effects of the virus in the rearview mirror is, in many ways, a new starting point for what lies ahead. With that in mind, I want to lay out just some of the opportunities and challenges that await FRSA and the Florida roofing industry it represents.

Training

As we rebound and start rehiring, attracting new folks to the industry, providing appropriate training will be more important than ever. Roofing is becoming more complex every year. New materials and application methods, along with more complex NRCA ProCertification tile testing.

18

FLORIDA ROOFING | April 2021

and stringent building codes, demand that we as an industry respond by training our workforce.

Recently, I had the opportunity to attend a pilot testing program for the National Roofing Contractors Association’s (NRCA) ProCertification for Clay and Concrete Tile Systems held at Trent Cotney’s impressive facility in Tampa. If you are into cars, and who’s not, you know how impressive early transportation advertising signs can be. If you are into roofing, which you must be if you’re reading this, Trent’s shop area behind his offices is every bit as impressive. His collection of roofing-related signs and memorabilia from the twentieth century was a stroll down memory lane. Thanks, Trent, for all you do.

Back to the tile testing. Once those participating in one of the ProCertification modules completes a course, he or she will need to take a final hands-on exam demonstrating experience and knowledge of that particular module. A qualified accessor oversees the hands-on demonstration. Attending as an accessor was Trent’s instructor and master mockup fabricator, Jim Montague. NRCA had a great group there that included: John Schehl, Jared Ribble, Jon Goodman and Frank Perna. Representing Eagle Roofing Products and FRSA was the always willing and invaluable Manny Oyola. He was not only helping with the students' hands-on roof tile evaluation but was also acting as an interpreter. FRSA is

FRSA Codes Committee meeting.

hoping to partner with NRCA to further develop and implement this program in Florida.

FRSA’s Educational Foundation has continued to offer both virtual and in-person roofing-specific seminars. Recommended social distancing and masking procedures have been implemented during in-person seminars that have taken place in the Training Center at FRSA’s new headquarters building in Orlando. The in-person seminars offer two hours of continuing education (CE) credit that covers major roofing-related changes in the 7th Edition (2020) Florida Building Code (FBC). I have served

20

FLORIDA ROOFING | April 2021

as the instructor for this portion of the seminars. An additional hour of CE covers the changes in the new FRSA-TRI (Tile Roofing Industry Alliance) Florida High Wind Concrete and Clay Installation Manual 6th Edition. The instructor for this portion of the seminars is Manny Oyola. The industry is very fortunate to have Manny’s continued dedication.

The FBC and tile manual seminars, as well as many more great seminars, will be offered during FRSA's 99th Annual Convention and the Florida Roofing & Sheet Metal Expo (July 21-23, 2021). We have a very knowledgeable and interesting group

Roofing Apprenticeship participants learning via Zoom meetings

of speakers and instructors who are dedicated to improving their industry. I, for one, can’t wait.

We have also developed a one-hour version of the 2020 FBC updates that we recently presented for two of our affiliates as a non-CE webinar. I am available to schedule this course for other affiliates virtually and, hopefully very soon, in-person. If you’re interested, contact me to arrange possible presentations for your group.

Manny and I have also recently presented an

early morning seminar and a luncheon seminar for the Palm Beach County Building Officials on both the tile manual and the one-hour FBC changes. Our presentations seemed to be well received. We will be planning similar events in the near future.

In April, we will be presenting a recruitment and hands-on training course at the Future Builders of America (FBA) Summit. This is a great opportunity to expose young people who already have an interest in construction to the roofing industry and the

www.floridaroof.com | FLORIDA ROOFING

many possible career paths that it offers.

The Associated Builders and Contractors (ABC) and FRSA Apprenticeship Program is proceeding very well, especially when you consider that the majority of the classes are being presented via Zoom meetings. We have a great group of students.

Clay Thomas of Advanced Roofing, Ft. Lauderdale is doing most of the heavy lifting here. I jump in when I’m available to help out. Across the state, there are several of these programs taking place with a great team of instructors and volunteers.

Clay Thomas and Tyler Allwood, Eagle Roofing Products, are among some FRSA regulars who are serving as subject matter experts (SME) for the development of a college credit roofing curriculum for the National Center for Construction Education and Research (NCCER). I am happy to be a part of this great group of SME from across the country who are participating in this endeavor.

FRSA is also working on an entry level training program titled FRSA Introduction to Roofing Technology. It is coming along nicely thanks to the efforts of the Worker Training Subcommittee.

Legislation

Many of this year’s slate of legislative bills involve items that effect our industry and are technical in nature. Property insurance reform in particular is a hot topic. Many of these bills are meant to address the growing number and cost of water damage and roof replacement claims. Our Codes Committee and Codes Subcommittee are working closely with our Governmental Affairs Committee and our lobbyist, Chris Dawson, to offer our advice and assistance, which includes coordinating efforts with other trade groups we regularly work with on code issues. There are also other proposed bills that effect the building code and its enforcement.

Of particular interest is limiting the enforcement of local amendments that have not been properly adopted and haven’t been provided to the Florida Building Commission staff for inclusion as local amendments. FRSA’s lobbying efforts also include construction defects and workers’ compensation bills. Chris is becoming more familiar with our industry and excelling while doing so. We’re lucky to have him on our team.

The Petition for Declaratory Statement (DS 2021007) was seeking the Commission’s position on whether the replacement of non-damaged areas of a roof should be computed within the 25 percent threshold limit set forth in 706.1.1, Florida Building Code. FRSA joined the petitioner, SDii Global Corporation, in its position that repair of non-damaged areas of a roof should not be computed within the 25 percent threshold limit.

FRSA’s motion supported the petitioner’s interpretation of the Building Code, noting that it is a reasonable and logical interpretation of the Code.

FRSA pointed out that a contrary interpretation of the Code would result in immense economic waist, unnecessarily burden property owners and restrict roofing contractors’ discretion to salvage otherwise viable roofing systems. FBC staff analysis agreed with the petitioner and has forwarded the petition to the Commission for a vote in April.

Trent’s team also represents FRSA, and the industry, before other regulatory boards such as the Construction Industry Licensing Board (CILB) and the Department of Business and Professional Regulation (DBPR). Much thanks to Trent and his team for all their hard work!

Building Codes

While we are still digesting the many changes in the 2020 FBC and then diligently working to inform our members and others about them, we are already deep into our next triennial cycle code adoption process. You can see by reviewing the Workplan for the 8th Edition (2023) FBC Update Development Tasks (pages 24-25) that it is an involved and ongoing process. The first task is to review changes brought into our code from the International Building Code (IBC). Which IBC changes eventually will be presented to the FBC Technical Advisory Committees (TACs) and then to the Commission, will be determined by the Commission staff. We have reviewed the roofing-related changes in the 2021 IBC, which allows us to see what might be coming in May and helps us to respond accordingly.

Our Codes Committees have already began discussing and developing code change modifications that FRSA will present beginning in January 2022.

All other proposed modifications presented by the public will also be submitted by then as well. At that point, we will develop and present our positions Declaratory Statement on all of these modifications. Between then and In March, FRSA, through our legal team from Cotney March 2023, we will testify and attempt to have our Attorneys and Consultants, submitted a motion to positions included in the new code. Reviewing and intervene in a petition before the Florida Building tracking these changes is important and takes a Commission (FBC) regarding the Florida Building Code’s threshold limit for the percentage of a roof area group effort. We are fortunate to have knowledgeable and involved volunteers on both our Codes that may be repaired before replacement of a comCommittee and Subcommittee to help in this effort. plete roof covering is required.

Florida High Wind Concrete and Clay Tile Installation Manual FRSA–TRI Alliance December 31, 2020 (12-31-20)

The 6th Edition FRSA-TRI Florida High Wind Concrete and Clay Roof Tile Installation Manual, developed by FRSA and the Tile Roofing Industry Alliance (TRI), launched with the 2020 Florida Building Code (FBC) and is the reference standard for tile installation outside of the HVHZ. The High-Velocity Hurricane Zones (HVHZ) utilizes the roofing application standards (RAS) 118, 119, 120 and 127 for their requirements for roof tile installation.

With the adoption of ASCE 7-16 into the FBC, roof design pressures have changed and more calculations or information from the tile manual tables are needed to establish uplift moments and the potential need for stronger attachments. Other notable changes include:

Mechanical Resistance Values on Plywood

■ Matrix revisions for underlayment and flashing

For mean roof heights (MRH) above 60 ft, engineering calculations must be submitted for permitting. For attachment systems not listed in the table for 19/32” sheathing, use the allowable aerodynamic uplift resistance from Table 3 for 15/32” sheathing. The allowable aerodynamic uplift moments include a generic restoring gravity moment of 6.5 ft-lbf for a direct deck and a restoring gravity moment of 5.5 ft-lbs for a batten installation.

■ New project design flow charts

Mechanical Fastening Methods

■ Design attachment system examples

26

A design flow chart (page 28) has been added to the 6th Edition tile manual to assist contractors in determining the required design pressures for underlayment and the uplift moment for the tile (Table 1A, page 30 and Table 2, page 31). Once these pressures are established, you’ll need to select an underlayment that meets the pressures by using either the twoply asphalt applied hot mop underlayment fastening system (Table 1, page 30) or the underlayment manufacturer's product approval. Then you will need to select the tile attachment from Table 3 (page 29) or the foam manufacturer’s product approval. Fill in the chart based on the roofing system you select and the different components needed for your roof design.

installation of tile in the specific regions of the country that are identified by FBC/IBC as subjected to wind speeds in excess of 110 miles per hour (Vasd), may be required to have additional fastening options not found in Table 3.

TRI has derived various uplift resistance values for nail, screws and adhesive fastening systems on plywood sheathing. Some of these methods of installation may have limiting factors depending upon wind speed, roof slope and roof height. Please consult with your tile, underlayment and adhesive manufacturers or design professional for additional information about these optional systems for those unique installations.

The following design aids are provided to the roof designer for consideration in determining the required aerodynamic uplift moment for roof tiles for wind applications beyond the prescriptive requirements in

the FBC. These tables were developed based on the requirements of ASCE 7-16 for a tile factor of 1.407 ft3.

The tile factor (TF) is determined from the following equation: TF = b*L*La(ft3) where: b = exposed width (ft) L = roof tile length (ft) La = 0.76*L Or, use the tile factor ratio that provides the ratio of the actual tile to the 1.407 (ft3) that some manufacturers have in their formal Product Approvals.

Establishing Wind Speed

Applied Technology Council (ATC) is a nonprofit corporation whose mission is to develop and promote state-of-the-art, user-friendly engineering resources and applications for use in mitigating the effects of natural and other hazards on the built environment. It offers a wind speed calculator on its website at www.atcouncil.org/windspeed that provides users with site-specific hazard information that can be used to determine design loads for buildings and other structures. Values are site-specific for the location entered and users are cautioned to provide the most accurate location for the building or structure site by specifying either the known street address, city and state or the latitude and longitude to at least five decimal places.

The report generated on this page (left) shows the wind speed at Risk Category I at 126 mph. You’ll include this information in the design flow chart for project location.

OSHA UPDATES

OSHA Issues New COVID-19 Guidance

On January 21, the day after being sworn into office, President Biden issued an Executive Order on Protecting Worker Health and Safety. The Executive Order directed the Secretary of Labor to issue, within two weeks of the date of the Order, revised guidance to employers on workplace safety during the COVID-19 pandemic. Less than 10 days later, OSHA released updated guidance for mitigating and preventing the spread of COVID-19 in the workplace.

The guidance suggests that the most effective way to mitigate the spread of COVID-19 in the workplace is to implement a COVID-19 prevention program. It includes suggestions for an effective COVID-19 prevention program, including but not limited to, the following elements: ■ Assignment of a workplace coordinator responsible for COVID-19 issues.

■ Education and training workers on COVID-19 policies and procedures using accessible formats and in a language they understand.

■ Providing face coverings to employees at no cost.

■ Making a COVID-19 vaccine or vaccination series available at no cost to all eligible employees.

■ Consider protection for workers at higher risk for severe illness through supportive policies and practices.

■ Performing enhanced cleaning and disinfection after workers with suspected or confirmed COVID-19 have been in the facility (this includes closing areas, and cleaning and disinfecting all immediate work areas and equipment).

■ Employers must implement protection from retaliation and set up an anonymous process for workers to voice concerns about COVID-19 related hazards.

■ Not distinguishing between workers who are vaccinated and those who are not.

■ Minimizing the negative impact of quarantine and isolation on workers (allow workers to use paid sick leave and the Families First Coronavirus Response Act paid leave).

■ Implementing quarantine and isolation rules consistent with CDC guidance.

OSHA’s updated guidance also includes links to industry-specific guidance. The construction industry guidance suggests various engineering and administrative controls, as well as safe work practices, for the workplace depending on the exposure risk level associated with construction work tasks. Notably, OSHA does suggest requiring construction workers to wear cloth face coverings in construction.

36

FLORIDA ROOFING | April 2021

Importantly, the guidance does make it expressly clear that it is not a standard or regulation and it creates no new legal obligations for employers. The guidance is intended to provide recommendations, as well as descriptions of existing mandatory safety and health standards. The recommendations are advisory in nature, informational in content and are intended to assist employers in recognizing and abating hazards likely to cause death or serious physical harm as part of their obligation to provide a safe and healthful workplace.

OSHA’S Penalty Amounts Increase for 2021 For 2021, penalties for an other-than-serious violation, a serious violation and a failure-to-abate violation increased to $13,653, which represents a $159 increase over these same penalties in 2020. Willful and repeat violations now have a maximum penalty amount of $136,532 per violation, which represents an increase of $1,626 over last year’s maximum penalty amount for willful or repeat violations.

In light of this increase in OSHA penalty amounts and the fact that the Biden administration promises increased enforcement efforts, it is a good time to revisit your company safety program to make sure you are taking those steps necessary to defeat a citation based on the unforeseeable employee misconduct defense. To establish the affirmative defense of unforeseeable employee misconduct, an employer must show that it: 1. Established work rules designed to prevent the violative conditions from occurring, 2. Adequately communicated those rules to its employees, 3. Took steps to discover violations of those rules, and 4. Effectively enforced the rules when violations were discovered.

While most roofing contractors have work rules, provide training, inspect their jobsites and discipline employees who violate safety rules, it is absolutely imperative that documents are maintained that provide evidence of the same and that the company’s safety program, especially its disciplinary component, is effective such that violations are truly unforeseeable.

Even verbal reprimands should be documented. All documents which would support the affirmative defense of unforeseeable employee misconduct should be well organized and stored in a safe place for easy access in the event the company is cited for an OSHA violation.

Stay Healthy, Stay Productive

Yes, a vaccine is finally rolling out to prevent the further spread of the sometimes-deadly COVID-19 virus.

But the process will be slow going and you must continue to keep your crew safe and healthy during this taxing time. Doing so is not only the right thing to do, but it will also help you keep your company productive.

The Occupational Safety and Health Administration issued guidelines for safe working in April 2020 and companies should continue to follow them.

■ If workers are sick, encourage them to stay home.

■ Ensure your workers know how to properly wear face masks over their noses and to mask-up when working within six feet of each other.

Russ Lynn, GAF, Florida Regional Sales Director Commercial Roofing Products, 15 years How did you get started in the roofing industry?

After graduating from college with a degree in Architecture, I accepted my first job with an architectural firm in Orlando that specialized in commercial roof consulting. It was a relatively small firm and offered the opportunity to learn a lot about the industry from the consultant’s side. After spending 12 years there I accepted a position with a large commercial roofing contractor in Central Florida. For the next 9 years, I quickly came to realize that this part of the industry is where the rubber meets the road or, more appropriately, where the asphalt meets the roof. I learned a lot about this part of the industry. From sales and estimating to operations and service, there was a great deal to learn. After getting my contractor’s license, I eventually became responsible for managing the business.
