The most common and popular form of roofing is asphalt shingles. Asphalt shingles provide the protection your roof needs from inclement weather conditions.
Asphalt shingles have three components: a mat made from fiberglass or cardboard, an asphalt coating and a covering of granules. It is the asphalt that sheds the water. Shingles are designed so that the granules block the UV of the sun and protect the asphalt.
