Signs Your Flat Roof Needs Attention

These are the warning signs we look for on a low slope or flat commercial roof:

  • Ponding Water Standing water after a rain is hard on a flat roof and points to drainage problems.
  • Lifting or Open Seams Seams that lift or separate are a common entry point for leaks.
  • Interior Leaks or Stains Water inside the building means the membrane needs attention now.
  • A Roof Near End of Life An aging flat roof is better replaced on a plan than in an emergency.

FAQs About Flat Roofing

What flat roofing systems do you install?

TPO, EPDM, and modified bitumen systems, plus roof coatings for sound roofs that do not yet need replacement.

Can a coating save my roof?

If the roof is structurally sound, a coating can extend its life and delay a full replacement. We will tell you honestly which makes sense.

How do you handle ponding water?

We build in proper slope and clear drainage so water leaves the roof instead of sitting on it.

Do you offer maintenance plans?

Yes. Scheduled inspections keep a commercial flat roof at its full service life and protect your warranty.
