Technical Data Sheet <br />Landmark®TL Shingles <br />PRODUCT INFORMATION: <br />The Landmark®TL shingles are constructed using three laminated <br />layers of the industry’s most durable materials, providing a dramatically <br />thick roofing product styled with the classic appeal of wood shakes. The <br />overall dimensions of this shingle are 13 1/4" x 40". It is designed to <br />resist blow off in high wind conditions up to 110-mph with normal <br />installation and 130-mph with special installation. <br />Landmark TL algae resistant (AR) shingles help protect against staining or discoloration caused by algae. <br />AR shingles are not available in California. <br />Colors:Please refer to product brochure or CertainTeed website for the colors available in your region. <br />Limitations:It is recommended to apply these shingles at slopes of 4" per foot and greater in order to <br />achieve optimum appearance. Low slope applications (2:12 to < 4:12) require CertainTeed’s <br />WinterGuard£Waterproofing Shingle Underlayment, or its equivalent meeting ASTM D1970, to be <br />applied to the entire deck surface, according to application instructions provided with the product and on <br />the shingle package. In areas where icing along the eaves can cause the back-up of water (all slopes); <br />apply WinterGuard, or its equivalent, according to application instructions provided with the product and <br />on the shingle package. <br />Product Composition:Landmark TL shingles are composed of a fiber glass mat base. Ceramic-coated <br />mineral granules are tightly embedded in carefully refined, water-resistant asphalt. Three pieces of the <br />shingle are firmly laminated together in a special, tough asphaltic cement. All Landmark TL shingles have <br />self-sealing adhesive strips. <br />Applicable Standards: <br />ASTM D3018 Type 1 <br />ASTM D3462 <br />ASTM E108 Class A Fire Resistance <br />ASTM D3161 Class F Wind Resistance <br />ASTM D7158 Class H Wind Resistance <br />UL 790 Class A Fire Resistance <br />ICC-ES ESR-1389 & ESR-3537 <br />CSA Standard A123.5 <br />Miami-Dade County Product Control Approved <br />Florida Product Approval # FL5444 <br />Meets TDI Windstorm Requirements <br />Technical Data: <br />Weight/Square (approx.): 305 lb. <br />Dimensions (overall): 13 1/4"x 40" <br />Shingles/Square: 64 <br />Weather Exposure: 5-5/8" <br />INSTALLATION <br />Detailed installation instructions are supplied on each bundle of Landmark TL shingles and must be <br />followed.
