Flat Roof Repair in Austin: what we actually do
Flat roof leaks rarely show up where the water actually enters the building. Water tracks along the underside of the deck, runs along a beam, or pools at the lowest point before it drops through the ceiling. Twenty-seven years of Central Texas flat-roof repair calls means we know how to trace the leak to the source before we quote the fix.
We repair every flat-roof system we install. Modified bitumen seam repair, TPO patch and weld, EPDM section replacement, and torch-down repair on legacy pitch-and-gravel. Most repairs we run in the Austin metro fall in the $550 to $2,800 range. About fifteen percent of the flat-roof repair calls we run end in our recommending a replacement instead, because the membrane is past the point where another patch throws good money after bad. We will tell you that straight.
Emergency tarp service available within 24 hours for active leaks during storm season. Two-year workmanship warranty written on every repair.
Leak diagnosis to the source
We trace the water path. Flat-roof leaks often track ten to twenty feet from the entry point before they show up on the ceiling. No guesswork, no roof reseal-everything pitch.
Modified bitumen seam repair
Failed seam stripped, fresh cap sheet torch-applied and hand-feathered. The bond holds because the seam is brought to exact temperature. Hot enough to fuse, not hot enough to leak through.
TPO patch and hot-air weld
Punctured or split TPO membrane patched with matching material and hot-air-welded at every overlap. The weld is stronger than the parent membrane when done right.
Torch-down repair on pitch-and-gravel
Failed section of legacy pitch-and-gravel stripped, base and cap sheet torch-applied to the surrounding original system. Hand-feathered transition so the seam holds.
Drain and scupper rebuild
Clogged or back-pitched drains rebuilt. Failed scuppers replaced where the membrane has split around them. Pitch pans repoured. The detail work that decides whether the next storm leaks in the same spot.

A TPO membrane patch with hot-air weld runs $700 to $1,400. A pitch-and-gravel section replacement with torch-down runs $900 to $2,200.
Can you trace a flat roof leak before I commit to a repair?
Yes. About forty percent of the flat-roof calls we run end in the leak source being ten to twenty feet from where the water shows up on the ceiling. Water tracks along the underside of the deck and along beams before it drops through. We trace the path on-roof and in the attic before we quote the fix. The diagnostic itself is included in the free inspection.
Do you offer emergency tarp service for an active flat roof leak?
Yes. Emergency tarp service within 24 hours for active leaks during storm season. The tarp buys you a dry interior while we scope the permanent repair. Tarp service runs $350 to $750 depending on access and roof size, and credited toward the permanent fix if you book it with us.
What warranty do you write on flat roof repairs?
Two-year written workmanship warranty on every flat-roof repair we run. If the same spot leaks again within the warranty period, we come back at no charge. One of the few Austin crews that writes a multi-year workmanship warranty on flat-roof repair work.
When is a flat roof repair not worth doing?
About fifteen percent of the flat-roof repair calls we run end in our recommending a replacement instead. If the membrane is more than 80 percent of the way through its service life, if there are multiple seam failures across the field, or if the deck below has rot, the next dollar is better spent on a replacement than on another patch. We will tell you that straight.
Do you repair commercial flat roofs?
Yes. Commercial flat-roof repair is a regular part of our weekly workflow. Property managers and ownership groups across the Austin metro contract us for emergency repair, seasonal maintenance, and pre-replacement scope work. See our commercial roofing page for the property-manager workflow.
