Roofing Coatings

HBS Roofing coatings are commonly used in roofing assemblies that create an economical and effective roofing system for applications over new and existing roofing substrates in order to extend the life of the current roof (weather roof system).  HBS Roofing Coating Systems protects, preserves, and prolongs the life of commercial and multi-family roofs.
