Signs Your Flat Roof Needs Repair

Flat roofs fail differently than pitched roofs. The problems announce themselves in specific ways:

  • Standing water 48 hours after rain. Ponding water is a flat roof’s fastest killer. Membrane wears at the water line, seams open under prolonged saturation.
  • Interior stains, drips, or bubbling ceilings. Water almost always travels from its entry point before showing up inside, so the stain rarely sits directly under the leak.
  • Visible tears, splits, or bubbles in the membrane. Common on aging TPO, EPDM, and modified bitumen surfaces after summer heat cycling.
  • Failed seams or lifted flashing. Where the membrane meets a wall, penetration, or drain is where most leaks start.
  • Blistering or alligatoring. Surface texture changes signal UV and thermal damage that’s approaching failure.
  • HVAC or equipment damage nearby. Rooftop units cause leaks when their curbs shift or their pans fail. Not always the roof’s fault, but always our job to identify.

If you’re seeing any of this on a commercial or industrial building in DFW, call before the next storm.

Commercial Flat Roof Systems We Repair

We repair all major commercial flat roof systems, including:

Repair or Replace?

Not every failing flat roof needs a full replacement, and not every leak can be repaired long-term. Repair usually makes sense when:

  • The system is under 15 years old
  • Damage is isolated to specific seams, penetrations, or areas
  • The membrane is generally sound outside the damaged spot
  • Underlying insulation is dry

Replacement makes sense when:

  • The roof is 15+ years old and has had multiple repair events
  • Ponding is widespread
  • Insulation below the membrane is saturated
  • Damage covers more than 25-30% of the surface

If a repair extends the roof’s life meaningfully, we recommend the repair. If we’d be putting good money after failing material, we’ll tell you that too and point you at our commercial flat roof installation page to plan the replacement.

Storm Damage and Insurance

Wind damage, hail damage, and storm-related failures on commercial flat roofs are often insurance claims. T Rock inspects, photographs, and documents damage in the same Xactimate format your insurance adjuster uses, and we meet with adjusters on site. We handle the documentation and the work.

What we don’t do: T Rock is not a public adjuster. Texas law prohibits contractors from acting in that role, and we don’t try to. We can’t guarantee your insurance company will cover your claim, adjust your settlement, or negotiate your coverage on your behalf. Coverage decisions are between you and your insurance carrier.
