GAF’s color TPO membranes can transform a traditional roof into an aesthetic attribute. With standard colors, pre-formulated colors, and virtually unlimited custom colors, no other single-ply or metal roofing manufacturer offers more color choices than GAF. Decorative color membranes can complement overall building aesthetics or shingled areas. Most color choices include “Cool Color” technology, helping to increase reflectivity and reduce energy costs. The pigments have been specially selected to minimize fade.
TPO membranes are installed fully-adhered, mechanically-attached or ballasted. Fully-adhered means that the roof is "glued" to the substrate using a special adhesive. What actually happens is the glue creates a chemical bond with the membrane. Mechanically-attached membranes are those that use some type of special screw-type fastener to secure it. The type of fastener will depend on the type of substrate but all fasteners are generally screw-type fasteners.
Properly installed TPO roof systems have service lives ranging from about 10 to 20 years, depending on the type of installation. Full removal of the existing roof, the amount of slope the roof has, weather conditions, as well as several other criteria contribute to the longevity of a roof's service life. Typically, if you remove an old roof down to the deck before installing a new one, then the new roof will last longer. Also, the steeper the slope and the less severe the weather conditions, the longer a roof will last.
