Common Commercial Roofing FAQs

1) What are signs of commercial roofing damage?

If you suspect you have roof damages look for damaged flat roof flashing such as bending, rusting, or any other damage. Also keep a lookout for cracked or blistered roofing surfaces and loose fasteners that cause bumps on the membrane itself. It’s a sign of trapped moisture and can lead to leaking.

2) How do I know if my roof has mold?

Some clear signs of mold are always foul odors or dark stains on your ceiling. The cause is most always water finding its way into your inner roof or upper walls.

3) What does roof maintenance include?

For the best commercial roof maintenance, we have to take into consideration the type and size of the roof. Many times, older more frequently used roofs may require more work and maintenance to keep it in the best shape possible.

4) How much does it cost to replace a roof?

Due to the code regulation, type of roof systems, and safety concerns around a given roof structure no dollar amount can be given at this time. Contact us for an inspection and estimate tailored to your property.

5) What roofing systems do you work with?

Our commercial roofers are skilled at installing and repairing TPO and PVC flat roofs and EPDM roofs.
