La Marque is an adjacent city whose mid-century ranch homes from the 1950s–70s were built for the refinery workforce.
Flat roof leak repair is membrane work: finding the breach in your TPO, EPDM, modified bitumen, or built-up roof and restoring it watertight. We use electronic and flood testing to locate the entry, then patch, re-seam, or re-flash with heat-welded or adhered materials matched to your system. Many of La Marque's original roofs have been replaced, but flashing details and valleys on the older homes are common leak sources.

Why Flat Roofs Leak in La Marque
La Marque is an adjacent city whose mid-century ranch homes from the 1950s–70s were built for the refinery workforce. We find failed seams, flashing pulling away at parapets and curbs, clogged drains causing ponding, and punctures from foot traffic or fallen branches.
The tricky part is diagnosis: water migrates under the membrane, so the interior stain can be rooms away from the breach. That's why flat roofs need proper leak detection, not guesswork.
- Clogged drains and ponding water
- Punctures from traffic or debris
- Deteriorated pitch pans and penetrations
- Failed or open seams
Our Flat Roof Repair Process
Once located, the breach gets a proper repair: cleaned and primed membrane, heat-welded or torched patches (never just caulk), re-flashed penetrations, and re-sealed drains. Patches are always larger than the damage and feathered into sound membrane.
We match the repair method to your membrane type — TPO gets heat-welded, EPDM gets primed and adhered, mod-bit gets torched. Its proximity to Highland Bayou means heavy rain events test drainage and valley capacity regularly. Wrong-method patches fail fast.
- Drains cleared and re-sealed
- Flood-tested before sign-off
- Repair matched to membrane type
- Heat-welded/torched — never just caulk

Flat Roof Leak Repair in La Marque FAQs
How do you repair a TPO/EPDM/modified bitumen roof?
With the method made for that membrane: heat-welding for TPO, primed adhesion for EPDM, torching for mod-bit. Matching the method to the material is what makes the repair last.
Do you work on commercial flat roofs in La Marque?
Yes — Many of La Marque's original roofs have been replaced, but flashing details and valleys on the older homes are common leak sources. our flat-roof crews handle both residential low-slope and commercial buildings.
Why is the stain so far from where you found the leak?
Water travels between the membrane and the deck on flat roofs — sometimes dozens of feet — before it finds a way inside. That's exactly why flat roofs need professional detection rather than patching above the stain.
