Maintenance Tips

• Inspect Roof Seals & Flashing Regularly – Check flashing, sealant, and roofing materials around the curb to prevent water leaks and roof damage. Proper sealing is essential for rooftop HVAC installations.

• Check Structural Stability – Ensure the curb remains level and securely attached to roof supports. The curb must stay square and properly supported to maintain safe equipment mounting.

• Inspect Galvanized Steel for Corrosion – The curb is built with 18-gauge galvanized steel, but periodic inspection helps catch rust or coating damage early.

• Keep Drainage Areas Clear – Roof curbs elevate HVAC units about 13¼ inches above the roof, helping prevent water buildup. Ensure surrounding areas remain clear so water can drain properly.

• Check Wood Nailer Strip Condition – The integrated 1" × 4" wood runner supports mounting and flashing. Inspect it for rot, damage, or looseness during routine rooftop maintenance.

• Verify Duct Openings Remain Unobstructed – Ensure supply and return duct openings in the curb stay clear and aligned with the rooftop unit to maintain proper airflow.

• Schedule Annual Rooftop HVAC Inspection – A professional check ensures the curb, duct connections, and rooftop packaged unit remain properly supported and sealed for long-term performance.
