Metal Roof Curbs

Metal Building Curb

Metal Roof Curbs provide a durable, insulated, watertight base for rooftop HVAC equipment on metal building roofs.

These prefabricated curbs are designed to integrate with metal roof profiles while meeting roof manufacturers’ requirements for support, insulation, and weather resistance.

Why Choose Curbs Plus Metal Roof Curbs?

✔ Designed for Metal Roof Systems — Engineered to integrate with metal roof panel profiles and meet roof manufacturer requirements.

✔ Insulated for Efficiency — 1½″ fiberglass insulation helps reduce thermal transfer and condensation issues.

✔ Watertight Construction — Mitered, welded corners ensure a weather‑tight seal around rooftop equipment.

✔ Durable Materials — Available in 18 ga. or 14 ga. prime galvalume steel for corrosion resistance and strength.

✔ Multiple Mounting Options — Loose or welded clip options accommodate various metal roof attachment methods.

✔ Custom Color Options — Available in custom painted finishes to match roof color and aesthetics.
