What is the most common type of roofing material used in homes?

The most common type of roofing material used in homes is asphalt shingles. They are widely used in the United States and Canada due to their affordability, durability, and ease of installation. Asphalt shingles are made of a fiberglass mat, coated with asphalt and covered with granules, which help protect them from the sun's UV rays.

Asphalt shingles come in a variety of styles and colors, allowing homeowners to choose a look that fits their home's aesthetic. They can last up to 30 years, depending on the quality and maintenance.

Other common types of roofing materials used in homes include metal roofing, which is known for its longevity, durability and energy efficiency, and tile roofing, which is popular in warmer climates due to its ability to reflect heat and keep homes cooler. Other materials like wood shake, slate, and concrete are less common and often more expensive.
