Commercial Roofing FAQs

Why do I need a roof curb for my HVAC unit?

Installing an HVAC unit on a roof curb is essential for:

• Proper Drainage: The curb elevates the unit above the roof surface, allowing water to drain away from the unit, preventing corrosion and potential damage.
• Waterproofing: The curb provides a solid base for flashing, ensuring a watertight seal around the unit's penetration point.
• Airflow: A properly designed curb allows for adequate airflow around the HVAC unit, improving its efficiency and preventing overheating.
• Maintenance Access: The curb provides a stable and accessible platform for maintenance personnel to service the HVAC unit.

How often should my commercial roof be inspected?

Commercial roofs should be inspected at least twice a year:

• Spring: After the winter months to assess any damage from snow, ice, or freezing temperatures.
• Fall: Before winter arrives to ensure the roof is ready for harsh weather conditions.

Additional inspections are recommended after any severe weather event, such as a hailstorm, strong winds, or heavy rain. Early problem detection can save you money and prolong roof life.
