Understanding Commercial Roofing Components

Updated: Jun 22, 2023

Commercial Roofing Components

When you need to repair or replace your commercial roof, you’ll probably come across roofing terms that are unfamiliar to you. Fear not! Here’s a brief description of the components of many low-slope commercial roofs.

Low-slope commercial roofs are often made up of three layers:

  • Roof deck. The roof deck is the base of the roofing system. It attaches to the roof structure and supports the weight of the roof.

  • Cover boards. Next comes a layer of insulation and cover boards that protect the roof from damage.

  • Roof coating. The top layer is the roof coating or membrane that provides weatherproofing. Aggregate or ballast may also be used on the roof, depending on the type of coating selected.

  • Other components include roof flashing and vapor retarders.
