Even with a regularly scheduled maintenance program in place, a roof will leak when the existing roofing system is beyond its serviceable life. When this occurs, the cost of temporary solutions may not be justifiable. At Evergreen Roofing, issues related to time of year, occupancy, building code requirements, budget, and the owner's intended use of the building will be addressed. These concerns, along with a physical investigation of the existing system to address technical issues, provide the necessary information to help us best select a roofing system that will meet the owner’s objective. Replacements include Composition shingles, single-ply roof membranes PVC & TPO, built-up roofing with modified bitumen, and wood shake and shingle.
