How do I prevent ponding water on my commercial roof?

Ponding water, the accumulation of water on a flat roof, can lead to:
  • Leaks
  • Structural damage
  • Premature roof deterioration
To prevent it:
  • Proper Design and Installation: Ensure your roof has a sufficient slope for proper drainage during the design and construction phase.
  • Regular Inspections and Maintenance: Inspect the roof regularly for clogged drains or debris buildup.
  • Repair Sagging Areas: Address any sagging or low spots on the roof, as they can trap water.
  • Tapered Insulation: Consider installing a tapered insulation system to create a gradual slope toward the drains.

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.

What are the signs that my commercial roof needs to be replaced?

Consider replacement if you see:
  • Persistent Leaks: Multiple or recurring leaks despite repairs.
  • Extensive Damage: Large areas of damaged or deteriorated roofing, beyond cost-effective repair.
  • Ponding Water: Persistent standing water after rainfall.
  • Sagging or Structural Issues: Sagging, deflection, or signs of structural damage.
  • Age and Deterioration: If your roof is nearing the end of its lifespan and showing signs of widespread wear and tear.
A professional roof inspection can definitively tell you if you need a replacement.
