What are Asphalt Shingle Roofs?
If you're looking for a new roof, the most common choice is asphalt shingles. An asphalt shingle roof is an investment that can pay off in big ways.
Asphalt shingles are made from natural materials like sand and mineral granules, which are mixed with asphalt or oil to form the final product. The composition of the asphalt mixture varies depending upon the brand and grade of shingle; some are made with recycled materials as well.
Asphalt shingles come in many different sizes, textures and colors. They can be installed over wood, concrete or steel decks (or other substrates), but they're typically installed directly on top of plywood sheathing or OSB (oriented strand board). The protective underlayment boards provide a barrier from moisture penetration into your home's interior walls and ceilings.
