Leaking roof repair in San Antonio starts with an honest answer: is this a single entry point, or is the roof telling you it is near the end? Here is how we tell.
You're in the right place
One entry point
Consider instead
Aging but dry
Consider instead
Water in the roof system
Leaks in more than one spot? A full roof inspection with an infrared scan shows every wet area before you spend money on patches.
After years of San Antonio roof leak repair calls, the same failure points come up again and again. We check all six before we decide where the water is coming from.
Months of 100°F days expand and shrink the membrane until weak seams open.
Wind-driven rain gets behind flashing and coping caps that stay dry in normal rain.
Boots crack in the sun and sealant shrinks away from pipes, conduit and supports.
Curb flashing fails, and clogged condensate lines drip water that looks exactly like a roof leak.
Debris after a storm backs water up until it finds a seam or a flashing edge.
Screws back out and washers dry-rot, opening many small holes on older metal roofs.
Stop the water first, then find the source, then fix it once.
A person answers 24/7. Tell us where water is showing and what is under it.
We stop active water with a temporary seal and protect stock, equipment and people below.
We check inside and on the roof, then use a moisture meter, infrared scan or controlled water test.

Most leaks are priced after one visit. These four things move the number most.
| Typical scope | Typical range |
|---|---|
| Leak investigation & diagnosis | $150 to $600 |
| Infrared moisture scan | $0.05 to $0.12 per sq ft |
| Single leak point: seam, flashing or penetration | $300 to $1,500 |
| Leak with wet insulation or a larger section | $1,500 to $15,000+ |
Roof still under a manufacturer warranty? We coordinate the repair so coverage stays valid.
Water over racking, server rooms, patient areas or tenant spaces goes to the front of the line.

A patch over the stain is a guess. We do not leave the roof until we know where the water got in.
How we approach every leak
Leak crews cover every part of San Antonio, Texas, inside and around Loop 1604, from Stone Oak and the Medical Center to the South Side. Drive times are from downtown.

If water drips on dry days while the AC is running, suspect a clogged condensate line or drain pan. If it only shows during or after rain, it is usually the roof. Leaks at rooftop unit curbs can be both, so we check the roof and the unit on the same visit.
Wind-driven rain gets behind wall flashing, parapet coping and joints that stay dry in normal rain. Those spots are often above the roof surface, so we water-test the walls and parapets, not just the field of the roof.
Usually, yes. We can divert water, seal the opening temporarily and protect what is below. Permanent membrane repairs need a dry surface, so they are scheduled once the roof dries.
Fixing a single leak point such as a seam, flashing or penetration usually runs $300 to $1,500. Diagnosis runs $150 to $600 when it is billed separately, and leaks that soaked the insulation can reach $1,500 to $15,000 or more. You get a fixed written price first.
Usually because it was patched where the stain showed, not where the water got in, or because wet insulation was left under the patch. We mark the entry point on a roof plan, replace wet insulation, and a maintenance plan catches the next weak spot early.
It depends on the cause and your policy. Sudden storm damage is often covered, while leaks from age and wear usually are not. We document the cause with photos and a written report you can send your insurer. We do not negotiate claims; in Texas that is the job of a licensed public adjuster.
