Flat and low-slope roofs are common on additions, patios, garages, townhomes and commercial buildings across Texas. Because water drains slowly from these roofs, small openings in seams or membranes can let a lot of water through. Flat roof leak repair focuses on the membrane, seams, drains and edges where water tends to sit.
Why flat roofs leak
- Ponding water that sits for days after a storm and works into weak seams.
- Split or separated seams in TPO, EPDM or modified bitumen membranes.
- Blistering and cracking from heat and sun exposure.
- Clogged drains, scuppers or gutters that back water up onto the roof.
- Failed flashing at walls, parapets, HVAC curbs and pipe penetrations.
Types of flat roofs a contractor may work on
- TPO and PVC single-ply membranes.
- EPDM rubber roofing.
- Modified bitumen (torch-down or self-adhered).
- Built-up roofing (tar and gravel).
- Roof coatings applied over an existing roof.
What to expect from the repair
On a flat roof, the leak inside the building can be a long way from the damaged spot because water spreads under the membrane before it finds a gap. Roofers often start by looking at areas where water ponds, at drains and scuppers, and at every seam and penetration near the leak.
Repairs range from patching a seam or a small puncture to rebuilding flashing around rooftop equipment. If the membrane is aged across the whole roof, a contractor may talk with you about a restoration coating or a replacement, and can explain the trade-offs for your building.
Keeping drains and gutters clear is one of the simplest ways to protect a flat roof, especially before the spring storm season and after leaves drop in the fall.

Questions about flat roof leak repair
Is some ponding water normal?
A small amount that dries within a day or two is common on low-slope roofs. Water that stays longer than that puts extra stress on seams and is worth having looked at.
Can a flat roof be repaired in sections?
Yes. Seams, punctures and flashing details are often repaired without replacing the whole roof, as long as the rest of the membrane is in reasonable condition.
Do you work on commercial flat roofs?
We connect callers with independent contractors. Many handle both residential and commercial low-slope roofs; ask the contractor about your building type when they call.
