Abstract

See full text

A membrane roofing system that includes a waterproof layer that protects an insulation layer and a granule coupled to the waterproof layer. The granule has a 60% or greater reflectivity that reduces transmission of ultraviolet light to the waterproof layer. The granule is coated in a fluorinated acrylic copolymer that resists adsorption and absorption of asphaltic chemicals by the granule from the waterproof layer.
