Liquid-Applied Coating Systems for Modified Bitumen and Metal Roofs

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. Elastomeric coatings from Kemper System

White Coating Improves Energy Efficiency

The Kemperol Reflect 2K FR from Kemper System is a cold, liquid-applied reinforced cool roofing system that can improve building energy efficiency. The white surface helps reflect sunlight and reduce the impact of infrared rays that can tax building cooling systems. The easy-to-apply, fully reinforced membrane is applied the same way as Kemper System’s Kemperol 2K-PUR solvent- and odor-free system, but the new liquid waterproofing pours out white and dries to a bright white. Because no topcoat is necessary, labor costs and installation times are reduced. The system consists of 70 percent rapidly renewable resources, is fire-rated for Class-A assemblies, and is odor-free and low-VOC.
