Though you may think that asphalt shingles are made up entirely of asphalt, they're actually made from various raw materials. Every manufacturer will have a unique blend of these materials. Most asphalt shingles are made from limestone that has been crushed into an excellent powder. This powder is then mixed with the asphalt to create a filled coating.
- 3-tab: These are the most traditional, basic kind of shingles. They typically have a very flat appearance and generally weigh and cost less than dimensional roofing shingles. However, three-tab shingles are decreasing in popularity and have almost completely disappeared.
- Dimensional/Architectural roofing shingles: Most homeowners prefer these types of shingles because they’re available in various colors, styles, and textures. Additionally, these shingles are typically thicker and offer more protection.
