Flat Roof Repair

Where They Leak

1. Curbs and rooftop equipment, which is also where the mechanical contractor was working last. That is not a coincidence.
2. Pipe and conduit penetrations, with failed pitch pockets and sealant-only details.
3. Drains and scuppers, where clamping rings loosen and the drain is no longer the low point after the insulation compressed.
4. Wall and parapet terminations.
5. Seams. A cold weld from the original TPO or PVC install fails years later.
6. Ponding areas, where standing water finds every weakness at once.

Ponding Is A Warning

Water standing more than forty eight hours after rain is a drainage defect. It adds structural load and degrades the membrane faster than anywhere else on the roof. Fixes run from rebuilding drains to adding scuppers to tapered insulation crickets, and which is right depends on why the water sits there.

Core Cuts Before Anything Else

Whether your insulation is wet decides everything that follows, and you cannot tell from the surface or from the roof's age. We cut cores and scan for moisture before quoting. Dry insulation under a tired membrane is a repair. Saturated insulation is a tear-off, and anyone proposing to coat over it is selling you a cover-up that traps the water.

How We Document It

Photos of every defect with roof plan locations, core cut results, moisture scan findings and a line item scope. On an insurance or warranty claim, that documentation carries the argument.

Drainage In A North Texas Downpour

North Texas rain does not fall gently for a day. A spring or fall storm can drop a large share of a month's total in an hour, and a low slope roof either moves that volume off the building quickly or holds it. Drains sized decades ago for a different roof assembly, strainers clogged with the cottonwood fluff that blows across the Metroplex in May, and a scupper set an inch too high all show up in the same downpour.

That is why we walk roofs during or right after heavy rain when we can. Standing water tells you where the deck has deflected, where insulation has compressed under traffic, and whether the drains are actually the low point. A dry roof on a July afternoon hides all of it. Ask your maintenance staff to photograph the roof mid storm, and send us what they get.
