First Claim
Patent Images
1. A method for constructing a ballasted roof system comprising:
- covering a roof structure with a polymeric roofing membrane and subsequently a ballast material;
applying to said ballast material a reflective paint to improve the solar reflective properties of the ballasted roof system, wherein said ballast material is a layer of ballast rock distributed about the roofing membrane; and
wherein said step of applying comprises the steps of;
first applying a coat of said reflective paint in a first direction; and
next applying a second coat of said reflective paint in a second direction substantially opposite said first direction.

Abstract
A method for constructing a ballasted roof system (20) includes the steps of installing a roofing membrane (14) onto a roof structure (12). A ballast (16, 32) is disposed on the roofing membrane, wherein the ballast has applied thereto a reflective paint (21) to improve the solar reflective properties of the ballasted roof system. The improved roofing system has solar reflective properties at least 35%.
