Abstract
A method and system for covering flat roofs. The method and system include weather-proof flat roof material with plural sealing components that do not require an open flame (e.g., from a blow torch) to seal a first and second piece of weather-proof flat roof material together. The weather-proof flat material can be used as a base layer, a ply layer used between a base layer and a cap layer, a cap layer, as flashings, on walls or as a substrate layer for flat roofs.
