Roofing contractors can transform existing modified bitumen roofs or metal roofs into white reflective cool roofs with two new roof recovery options from Kemper System. Roof Guardian RG-170 (SRI 109) is a Class A fire-rated elastomer-based coating system for prolonging the life of modified bitumen assemblies. Roof Guardian RG-180 system (SRI 108) is ideal for recovering metal roof assemblies.
The Roof Guardian line of liquid-applied elastomer-based roof coatings also spans solutions for smooth-surfaced built-up roofing (BUR), polymer-modified asphalt (PMA), and single-ply roof systems.
Both RG-170 and RG-180 are formulated using an acrylic polymer base that provides outstanding adhesion and superior reflectivity. The bright white finish reduces surface temperatures, thereby minimizing thermal expansion and contraction. Under-the-roof temperatures are also reduced, lowering energy costs. Formulated to resist cracking and peeling, both products provide excellent waterproofing capabilities and long-term mildew resistance. RG-170 and RG-180 are Energy Star and Cool Roof rated and now have 3-year weathering test results.
