Maximum-Stretch™ is a thick, high solids high-grade white elastomeric plastic coating and paint that stretches with the roof surface. Maximum-Stretch™ has several times the adhesive capability of most paint. It seals, saves and extends the life of old roofs and is an excellent choice for old tar roofs. Some surfaces such as EPDM, rubber roofs or vinyl will need a primer coat of Ames'® Super Primer™ for the best adhesion. It is white with a reflectivity of 90 to 98% to drastically reduce the roof temperature from as much as 120°F. It has remarkable adhesion to almost any surface including rolled roofing. This liquid elastic coating and sealant flows easily into cracks and crevices and dries to completely seal roof leaks. Maximum-Stretch™, along with Super Elasto-Barrier™ and roof fabric can be formed into a roof system to form a new roof over the old roof and substantially extend the life of the roof by many years. Maximum-Stretch™ roof coating resists cracking and drastically reduces the expansion and contraction that tears roofs apart. Maximum-Stretch™ remains flexible from -30° to 150° F. It has been developed for cold and wet weather and formulated to resist fungus, mold and mildew. Maximum-Stretch™ cleans up with water, contains no solvents and is easy to use. Just pour it out and paint it on.

We have a 95 year old Spanish style house that was impossible to keep cool during the summer. Our electric bill for last August alone was $600 and we still couldn’t get the living room temperature below 90 F….day or night.

This year we were almost ready to sign up for a $25,000 fix when I saw your site on the internet. I ordered 15 gallons of Maximum Stretch…enough for one coat on our roof. With my infrared thermometer, I took the temperature of the living room ceiling before I started. It registered 87 F. By that afternoon, I finished the very easy “pour it out and roll it on” application and the temperature dropped to 75 F.

Not only did we save the $25,000, we are saving $100 per week in energy costs and will pay for the products in less than 6 weeks.

Thank you Ames!
