WeatherMaster® Tile, a peel-and-stick roofing underlayment made from a proprietary SBS-modified asphalt and a woven polyester membrane, is designed for tile roof applications.
The woven polyester top surface of WeatherMaster® Tile aggressively bonds with the foam adhesives used in tile roof installations and can withstand the weight of stacked tiles without slippage or damage to its membrane surface. SBS-modified asphalt coatings also seal around nails to form a watertight barrier. WeatherMaster® Tile self-adhesive underlayment provides a tough, slip-resistant barrier to physical damage, UV degradation, weather and moisture.
WeatherMaster® Tile underlayment is designed specifically to enhance tile roofs and protect against water and extreme weather.

Learn and observe safe roofing practices according to OSHA and local building code requirements. Always use caution when walking on sloped roof decks and WeatherMaster® Tile underlayment. Do not walk on unsecured WeatherMaster® Tile or any other loose material lying on sloped roof decks. Dust, dew, water and debris create unsafe conditions on the roof. The presence of any foreign matter may drastically change the coefficient of friction (traction) on WeatherMaster® Tile or any other material on a sloped roof deck. Failure to always use proper safety equipment and footwear can result in serious injury or even death.
To begin, remove any dust, dirt, loose nails or other protrusions from the roof deck. Remove all shingles, roofing felt and nails from the deck of existing roofs. Sweep thoroughly to remove any dust and dirt. Apply WeatherMaster® Tile underlayment only in fair weather when air surface temperatures are above 45°F and rising. Apply to dry surfaces only.
Apply sheet parallel to the roof edge, extending over 1/4". Overlap edge seams 3", so that laps will shed water. End seams should be overlapped 6" and staggered. On slopes 6:12 and greater it is necessary to spot nail the top edge of the membrane every 12” on center during the installation process. For wrinkle-free application, cut WeatherMaster® Tile underlayment into 10 to 15 foot lengths and reroll.
Peel back 1 to 2 feet of release paper. Align the sheet on the lower edge of the roof and adhere the first 1 to 2 feet. Pull the release paper from under the sheet and continue to peel it while pressing the sheet into place. Roll lower edges firmly with a wallpaper roller or other hand roller. For ice dam protection, WeatherMaster® Tile underlayment must be applied to reach a point above the highest expected level of ice dams (minimum application at least to a height of 24" beyond the interior wall line). End laps should be overlapped 6" and staggered. When installing at temperatures below 45°F and on slopes above 8" in 12"—face nail in the overlap area at the top of the sheet at 12" OC. Priming the deck may be necessary below 45°F.
Cut WeatherMaster® Tile underlayment into 4 to 6 foot lengths. Peel the release paper and center sheet over valley or ridge. Drape and press sheet into place, working from the center of the valley or ridge in each direction. For valleys, apply the sheet starting at the lowest point and work upward. WeatherMaster® Tile underlayment should not be left permanently exposed to the weather. It must be covered by shingles, metal valley flashing or other roofing materials within 45 days. Overlap horizontal overlaps at least 6" in valleys. Smooth shank galvanized nails are recommended for fastening shingles. Do not overdrive nails or break the surface.
