CertainTeed FlintCoat® -A 300 is a premium fibered aluminum roof coating and when applied to the roof the aluminum flakes leaf to the surface, forming a reflective, metallic shield over the base of the coating resulting in a self-protecting roof coating with long lasting moisture and heat-resistant properties. FlintCoat -A 300 is a top performing aluminum coating for BUR, metal, and modified membranes.

  • Self-protecting--the aluminum shield protects the base coating's asphaltic oils so coating stays resilient
  • Reflects over 65% of the sun's rays
  • Prolongs roof life--helps protect roof membrane from UV degradation
  • Helps reduce energy consumption costs
  • Easy to apply
  • ENERGY STAR® labeled roof coating
