What is a common type of roofing system for residential buildings?

Asphalt shingles are a common type of roofing system for residential buildings due to their affordability, ease of installation, and versatility. They are widely used in North America and are available in a variety of colors and styles, making it easy for homeowners to find an option that fits their aesthetic preferences. The materials used in asphalt shingles are cost-effective, which contributes to their popularity among homeowners. Additionally, they have a relatively good lifespan, usually ranging from 20 to 30 years, depending on the quality of the product and the local climate conditions.

While metal roofing, clay tiles, and wood shakes are also options for residential roofing, they typically come with higher costs or require more maintenance compared to asphalt shingles. Metal roofing can provide durability but is less common in certain residential areas due to aesthetics or initial investment. Clay tiles are known for their longevity and charm but can be expensive and heavier, requiring additional structural support. Wood shakes, although attractive, require more maintenance and are less fire-resistant compared to asphalt shingles. Thus, asphalt shingles remain the most prevalent choice among homeowners for residential roofing systems.
