Course

Home / Glossary

A course refers to a row of shingles or other roofing materials that are installed horizontally along the roof deck. The term “course” is used to describe the placement of the shingles or other materials, as well as their overall location on the roof surface.

Courses are typically installed from the bottom of the roof up, with each course overlapping the one below it to provide additional protection against water infiltration and other types of damage. The amount of overlap between courses can vary depending on the type of roofing material and the pitch of the roof, but is typically between 2 and 6 inches.

Courses are an important consideration in roofing, as they can affect the overall appearance and performance of the roof system. Proper installation and alignment of courses is essential to ensure a durable and long-lasting roof, and can help to prevent water infiltration, wind uplift, and other types of damage.

Overall, understanding the concept of courses is an important part of the overall installation and maintenance of a roof system, and can help to ensure the continued durability and performance of the roof.
