In May, GM Roofing completed another building at the Joint Forces Base in Los Alamitos. After properly preparing the roof to begin installment, GM Roofing implemented a new Hydro Stop water proofing system. GM Roofing is a certified Hydro Stop applicator who has gained a lot of experience with the system in the recent years. When the new roof was finished, the system qualified for a 15-year, full labor and material warranty. Upon completion, GM Roofing began working on a second building on the base using the same system.
