The difference between a pitched and gently sloped roof can amount to quite a bit in terms of roofing materials and ease of repair. Roof pitch can determine whether one type of roof covering, say composite shingles, will work or if the pitch is below a certain amount, you might have to use a single ply membrane system, like Duro-Last.
Booth and Little is a well-respected Marin roofing company, established 96 years ago. Now, in its fourth generation of family owners, they provide both residential and professional roofing services in Marin, Sonoma and Napa Counties.
Roofing materials differ for commercial and residential buildings. Duro-Last roofing systems are more closely associated with commercial buildings and flat roofs. The reason is the slope of the roof.
