Roof Curbs

Custom Rooftop Curbs – Roof Curbs for HVAC and Exhaust

The highest potential for leaks on commercial and industrial roofs is around roof penetration areas, including where rooftop equipment or other accessories are installed. Roof metal building curbs solve this problem. With a properly designed, manufactured, and installed roof curb, penetrations can remain leak-free for many years. Fan, vent, skylight, and HVAC roof curb are commonly found on metal building roofs to seal these penetration areas.

As experienced roof curb manufacturers, R&S Roof Products offers metal building roof curbs that fit any Standing Seam, R-Panel, or insulated metal panel roof. They are available in aluminum, zinc-coated steel, or stainless steel to accommodate the climate conditions in your area and your budget. We also offer finishing options with our roofing curbs, whether mill or custom color.

Roof Curb Features

All curbs feature continuous seam welds. Side flanges nest with the roof panel, resulting in a complete watertight seal. Metal roof curbs come standard with 1″ foil-face rigid insulation (R6.5). High R-values are available upon request.
