Wachusett Exteriors is expert in asphalt roof installation, replacement and repairs. Asphalt shingles are made of a fiberglass mat that provides strength and tear resistance, with hot asphalt bonded to the top and bottom to create a waterproof barrier. Stone granules are then embedded into the top layer of asphalt to protect the shingle from degradation and add color and shading. Asphalt shingles can last between 15 and 30 years, depending on the type of shingle and the local climate and weather conditions
