ShakeMAXTM SlateMAXTM LAP ROOFING INSTALLATION GUIDE Read all instructions prior to installing any roofing product. Failure to install and finish this product in accordance with all local building codes, regulations and MAXITILE written application may lead to personal injury, affect system performance, violate local building codes, and void the product warranty. We suggest that you read these instructions at least twice.

ShakeMAX TM and SlateMAX TM are polyvinyl fiber reinforced cement roofing panels. ShakeMAX TM has a simulated wood grain texture. SlateMAX TM has a simulated slate texture. ShakeMAX TM and SlateMAX TM are available with straight edge and staggered edge. The panels are 16 inches long X 48 inches wide X Ÿ inch thick. To cover one square, 43 straight edge panels or 50 staggered edge panels are required. There are 300 pieces per pallet, sufficient to cover 7 squares using straight edge or 6 squares using staggered edge panels. Installed weight is approximately 4.9 pounds per square foot (23.9 kg/m²) for straight edge and 5.7 pounds per square foot for staggered edge panels.

STORAGE: MAXITILE products must be stored flat, and off ground, prior to installation. Protect products from direct exposure to the weather. To prevent damage keep roofing product in the original packaging until ready to install. Use the plastic bonnet provided to keep the product dry and prevent moisture from setting on the roofing. If ShakeMAX TM and/or SlateMAX TM should get wet, split the plastic wrap to allow for ventilation to prevent excessive water condensation. Accumulation of moisture in the bundles may cause mold or efflorescence. If MAXITILE products are stored outside they should be protected with an additional waterproof covering. Do not apply ShakeMAX TM and/or SlateMAX TM over wet roof sheathing or underlayment.


PITCH: 4:12 minimum, 21:12 maximum. Below 4:12 ShakeMAX TM and SlateMAX TM must be installed over an approved waterproof covering complying with the applicable building code.

ROOF DECK: ShakeMAX TM and SlateMAX TM must be installed over code-complying solid-wood sheathing. Minimum ½ inch rated 1 plywood decking for use with standard roof. See ICC Evaluation report for fire classification.

UNDERLAYMENT: Class “A” fire rating (New construction): One layer of non-perforated Type II (commonly called No. 30) felt in according with ASTM D 226 and one layer of 72-pound mineral-surfaced non-perforated cap sheet complying with ASTM D 3909 must be installed over code-complying solid-wood sheathing. In areas where the average daily temperature in January is 25 °F (- 3.9°C) or less, or where there is a possibility of ice forming along the eaves and causing a backup of water, the type II felt and the 72-pound mineral-surfaced cap sheet must be solid-cemented together with asphalt roofing cement, complying with ASTM D 4586, between the layers. The two layers must extend from the eave to a point 24 inches (610 mm) inside the exterior wall line of the building. Class “B” fire rating (New construction): One layer of non-perforated Type II (commonly called No. 30) felt complying with ASTM D 226 must be installed over code-complying solid-wood sheathing. In areas where the average daily temperature in January is 25 °F (- 3.9°C) or less, or where there is a possibility of ice forming along the eaves and causing a backup of water, the type I (No. 15) felt underlayment complying with ASTM D 226 must be applied shingle-fashion, and solid-cement together. The two layers must extend from the eave up the roofing to a point 24 inches (610 mm) inside the exterior wall line of the building.

CUTTING: Refer to the Material Safety Data Sheet (MSDS) for important safety practices prior the using any roofing product.

  MAXITILE recommends that all cutting of products be performed outdoors. Use mechanical ventilation when possible.   For irregular cuts and holes use jig saw or holes saw with masonry blade. Special round openings can be made by drilling several holes around circumference of the desired opening and tapping out center.   For score-and snap cutting, use carbide tipped scoring tool or a sharp knife:

2- Bend upwards and break.

  A HEPA vacuum should be used when cleaning up dry debris and dust from cutting area. Do not use compressed air, broom or brush. If you consider sweeping, wet down the floor and debris with a fine mist to suppress dust during sweeping. All scrap, cutoffs and debris should be disposed of in a covered container protected from the elements according to local codes. No special handling is required. WARNING: AVOID BREATHING SILICA DUST. MAXITILE roofing products may contain trace amount (< 0.5%) of crystalline silica, which is known to the State of California to cause cancer and is considered by IARC and NIOSH to be a cause from some occupational sources. Breathing excessive amounts of respirable silica dust can also cause a disabling and potentially fatal lung disease called silicosis, and has been linked with other diseases. Some studies suggest smoking may increase these risks. During installation or handling: (1) work in outdoor areas with ample ventilation; (2) use fiber cement shears for cutting or, where not feasible, use a dust-reducing circular saw attached to a HEPA vacuum; (3) warn others in the immediate area; (4) wear a properly-fitted, NIOSH-approved dust mask or respirator (e.g. N-95) in accordance with applicable government regulations and manufacturer instructions to further limit respirable silica exposures. During clean-up, use HEPA vacuums or wet methods, never dry sweep. For further information, refer to our installation guide and Material Safety Data Sheet available at www.maxitile.com or by calling (800) 3388453. FAILURE TO ADHERE TO OUR WARNINGS, MSDS, AND INSTALLATION GUIDES MAY CAUSE SERIOUS PERSONAL INJURY OR DEATH.

FASTENERS: Nails must be corrosion-resistant, preferably hot-dipped galvanized or stainless steel for best results, in according to local building codes. MAXITILE is not responsible for corrosion resistance of fasteners.

MAXITILE products can be hand nailed using a smooth-faced hammer, never use a waffle hammer, and fastened with pneumatic tools. In hand nailing, first perforate the opening to be used for fastening in order to avoid accidental breakage of roofing product. Always drive fasteners perpendicular to roofing and solid deck. Do not over-drive, under drive fasteners heads and never drive fastener at an angle. Fastener head must be flush on the surface of the product (no air space). If fastener is countersunk, patch fastener hole and add a fastener for roofing. Repair nail-sizes holes by filling with adhesive. Staples are not allowed

DECK PREPARATION: Apply the felt according with the fire rating desired. Fasten the roof felt with the minimum number of nails necessary to maintain a flat, secure surface. A 1 inch wide x ¼ inch thick kick strip should be fastened on top on the deck along the eaves. (A kick strip can be made from ShakeMAX TM or SlateMAX TM). Kicker strip must be positioned along the eaves. A kick strip is required to set the starter course on the correct angle and provide slots coverage, air spaces and solid backing for the first ShakeMAX TM and SlateMAX TM course. Space the starter strip to allow moisture to drain. If desired, install a 2 inches to 4 inches non-corrodible metal drip edge along the eaves and gables and fasten into the deck with nails spaced 9 inches on center. The metal edge flash should be bent downward to form a drip to protect the edge of the decking. Check to make sure the roof is square.

Straigth Edge Panel Installation 1) 1st Course. Install the first panel (full piece), starting at the lower left corner of the roof (starting at the right rake/ eaves corner is not permitted). Nail panel above slots, through previous course. Use six nails, drive two nails (at left and right edges of the panel) 1-½ inches to 2 inches from edges, all nails should be installed minimum of 1 inch above exposure line (be sure to nail through previous course not above). This will ensure the nails are concealed. Avoid driving nails between the slots because the heads may be visible through the slots of posterior courses. To minimize risk of lifting or curling, a generous dab of adhesive must be applied on or close to each nail. To ensure good adhesion, push down the overlapping panel after nailing. 2) Butt the next full ShakeMAX TM or SlateMAX TM panel lightly to the preceding panel and attach the panel to the roof in the same manner as the first ShakeMAX TM and SlateMAX TM panel. Continue from left to right horizontally across the roof. 3) If it is necessary, measure the last ShakeMAX TM or SlateMAX TM panel of every course. Measuring from left to right of ShakeMAX TM or SlateMAX TM, cut the right side at the correct dimension or if it possible use the cut end of other ShakeMAX TM or SlateMAX TM panel to abut at the end of the course in the roof.

The following is only a suggestion and is not intended to be a set of instructions. Each flashing situation will be slightly different. Review IBC Section 1507.3.9; IRC Section R905.3.8 or UBC Sections 1508.4 and 1509 for additional details for valley and flashing.

VALLEY: Roof valley flashing must be less than No. 26 gauge corrosion-resistant sheet metal (galvanized, stainless steel, or copper) applied over an underlayment of not less than No. 30 felt. The metal must extend at least 11 inches from the centerline in each direction and have a splash diverter rib not less that 1 inch high at the flow line formed as part of the flashing. Prior to installing ShakeMAX TM or SlateMAXTM at the valley conditions, install the asphalt felt, cant strip and metal flash as outlined in the standard installation method. After installation, center and apply a 36 inches wide layer of felt in the valley over the existing underlayment. The lower edge of the felt should be cut to conform and be flush with the metal eave flash. Do not nail into the valley metal. A minimum 12 inches lap is required when lapping these pieces. Secure the laps utilizing roofing cement and fasten the sheet smoothly in place utilizing the minimum number of nails required.

ROOF MAINTENANCE: Normal maintenance tasks will be in function of geographical area and exposure of the roofing; (before the beginning refers to your paint manufacturer for washing and recoating requirements related to paint performance); the tasks shall include but not be limited to:   In very humid climates, ShakeMAXTM or SlateMAX TM are subject to the growth of algae or fungus. Such growth, which is more of an esthetic problem than one of damage to the integrity of the material, can be eliminated with the application of certain fungicides. Check with fungicide manufacturers.   Cleaning out and repairs of gutters, flashing around pipes, chimneys, walls and protrusions, blocked pipes or flashing as required.   In order to maintain the integrity of your roof, it is advisable to periodically clean off debris, such as leaves and pine needles. Washing down the roofing surfaces between 6 to 12 months with a garden hose or low pressure

water spray to dirt and debris, or a medium bristle (nonmetal) brush are more suitable for cleaning fiber-cement products.   Do not clean up with high pressure water blast and sand blasting because may damage the surface and/or fibercement product. Avoid using steam or pressurized cleaning equipment on field tile roofing.

  Do not apply acid or soda directly onto fiber-cement surfaces. A diluted acid solution can be used to clean primer or painted fiber-cement surfaces. If this is necessary, add 1 part of muriatic acid to 5 parts water. Always saturate ShakeMAXTM or SlateMAX TM surfaces with water before applying cleaning agent, particularly when using acid solution.   A mild detergent and soft brush may be used for stubborn dirt or stain.   Re-applying of exterior finishes, refer to your paint manufacturer.   Patch damaged areas with a good quality spackling compound.   Brush or wipe surface to remove loose fibers, dirt or efflorescence. Remove oil and grease spots.   Ensure that surface is thoroughly clean and dry. Then either brush or spray a coating of top quality 100% acrylic latex exterior paint.

REPLACING A DAMAGED TILE: The application of roofer´s mastic or sealants to damages ShakeMAX TM or SlateMAX TM should not considered a viable repair alternative because these material, though effective at first, will eventually harden and crack thereby allowing water to enter. 1. Insert slate puller under damaged ShakeMAXTM or SlateMAXTM and snap off fasteners and adhesive. 2. Remove all damaged ShakeMAXTM or SlateMAXTM. 3. A new ShakeMAXTM or SlateMAX TM which should match the size, shape and texture is then slip into the place. Applied layer of polyurethane construction adhesive along the top of the replacement ShakeMAXTM or SlateMAXTMand held in position by MaxiClip inserted through the vertical joint between the pieces the courses above and hammer onto the deck.

Alternative methods for securing the replacement ShakeMAXTM or SlateMAX TM include metal hooks, nails, clips and straps also can used.

4. After placement, bend the vertical portion of the MaxiClip to secure the ShakeMAX TM or SlateMAX TM. Fasten replacement tile with nail through overlapping tile and apply exterior grade construction adhesive over nails head and paint it.
