STA-KOOL 770 Ultra White Elastomeric Roof Coating is a tough, highly flexible, rubberized roof coating. This high-performance, 7-year warranted elastomeric roof coating resists cracking and peeling. The coating also provides a highly protective barrier which reflects the sun's heat and destructive UV rays. This helps to cool roof surfaces and reduce interior temperatures. This product is an "investment" which can actually pay for itself in savings on cooling costs.
