What Are Some Uses for Rooftop Curbs?

April 5th, 2023 | Eric McClung

Roof curbs are used extensively on commercial roofs to ensure the safe installation and proper functioning of various components of the roof system, such as HVAC equipment, and more. These curbs are used on all types of flat roofs, including metal roof panels, modified bitumen, EPDM, and TPO. At R&S Roof Products, we offer roof curbs for metal commercial roofs that allow secure mounting and easy access to equipment on any roof type.

What Are Roof Curbs?

A roof curb consists of an elevated platform on top of a roof that supports roof penetration or roof equipment. Since roof curbs become part of the roof, they must prevent debris and moisture from getting underneath the roof while also providing a means to anchor pieces of equipment.

Aluminum and aluminized steel are ideal materials for roof curbs. The thickness of an aluminum curb should be 0.08 inch. Aluminized steel roof curbs are often available in 18, 16, and 14 GA sizes.

Uses for Rooftop Curbs

On commercial roofs you will find roof curbs for HVAC units, exhaust fans, stovepipes, vents and skylights, and other hardware. The type of curb used often depends on the type of equipment it is supporting.

In essence, when a commercial roof requires a portal that must be supported, roof curbs act as the support structure for the installed equipment, such as an HVAC units, while also serving as a strong barrier between the exterior environment and the building.

Since roof curbs must have sufficient strength to support hundreds, if not thousands of pounds of heavy equipment, they are often made from aluminized steel that has a 14-gauge thickness.
