What is Ames® Contouring Roof Fabric™?

Add strength to your project with Ames® Polyester Contouring Roof Fabric™ and resist ripping or tearing. Strengthens and resists puncture. Roof fabric gets embedded into your coating of choice and reinforces the surface.

Do-It-Yourself in three easy steps
Roof Fabric is normally set with Elasto-Barrier®, but in special cases may be set with Maximum-Stretch®, Snow Seal®, or Iron Coat®. Surface preparation is everything. Prepare the roof by removing dirt, moss and other debris. Power wash and let dry thoroughly. Prime the roof smooth and apply seam tape and Elasto-Barrier® to all joints and seams.

Step one: Starting at one end pour out a liberal amount of coating onto the surface. Use a push broom or roller to spread the coating out in a path slightly wider than the roof fabric being used. Roll the fabric into the wet coating until the coating comes up through the fabric and totally saturates it. This is best done by laying the roll of fabric down and pushing it forward into the wet coating with the push broom or roller while the excess coating comes up through the fabric. Avoid folds and wrinkles. Use a liberal amount of coating. The fabric will absorb almost two gallons per 100 square feet.

Step two: With the roller or push broom, pull the excess coating off to the side in preparation for laying the next row of fabric. Use the lap line on the fabric roll as a guide. One may butt or overlap the fabric. If you choose to overlap the fabric, overlap its entire length by three to four inches. Overlap may leave a seam. Repeat this process until the entire surface is completely covered with fabric. Allow to dry completely 24 to 48 hours.

Step three: To complete the roof fabric application process, apply an additional coat over the surface to completely seal and fill all remaining pinhole openings in the fabric. The goal is to have all pinholes filled and no less than 30 mils of thickness (a dime). The coating is best applied by pouring out and spreading. Topcoat with Ames® Maximum-Stretch™, Safe-T-Deck™ or Snow Seal® according to label specifications. Allow proper drying between coats.
