Asphalt roof shingles are also known as composite shingles. They are considered a “composition” product because of the way they are manufactured. A fiberglass or cellulose mat is saturated, covered with asphalt, and then layered with ceramic-coated mineral granules.
Asphalt shingles come in different thicknesses depending on the type of shingle and the manufacturer. The roofing professionals at All Phase Construction can help you understand all the available options.
