What is the typical exposure of a three tab asphalt shingle?

The typical exposure for a three-tab asphalt shingle is 5 inches. This measurement refers to the amount of each shingle that is visible or exposed after installation. Three-tab shingles are designed with a uniform appearance, and the 5-inch exposure helps to create a clean, traditional look for roofs.

This standard exposure also plays a crucial role in ensuring adequate water shedding to prevent leaks and protect the underlying materials from moisture damage. The exposure measurement is important for installers to adhere to, as it impacts both the aesthetic and functional aspects of the roofing system. Proper exposure contributes to efficient installation, ensuring that shingles are laid evenly and securely for optimal performance throughout their lifespan.
