Asphalt shingles are made of asphalt, a type of petroleum product. They're made by mixing sand, gravel, and other ingredients, rolling them out into sheets, and then cutting them into squares with grooves on the top side. These grooves help water run off the roof more easily.
These shingles come in various styles, shapes, and colors to match any home's aesthetic preferences. They're available in three basic types: three-tab, architectural shingles (also known as dimensional), and luxury shingles. 3-Tab asphalt shingles are standard-looking roofing materials that have been used for many decades. Architectural and luxury shingles have more elaborate designs that look more like tiles or slate than traditional asphalt shingles.
