Commercial roof leak repair and diagnosis in Central Texas

How do you find where the water is actually getting in?

We start inside, because the interior tells us what the roof cannot: where the stain is, what is directly above it, whether the water arrives during rain or hours later, and whether it only shows up when the wind is from one direction. Then we get on the roof and work the likely sources in order — seams and laps, terminations and edge metal, penetrations and pipe boots, curbs around equipment, drains and scuppers, and any place a trade has fastened something down since the roof went on. Where the entry point is not obvious, we test: flooding a drain, isolating an area, or opening a small test cut to see whether the insulation beneath is wet and in which direction it dries. The test cut is patched before we leave.

Where do leaks come from on each system?

On single-ply, it is nearly always seams, terminations and penetrations — a weld that was never fully fused, a termination bar whose sealant has given up, a boot that has split. On modified bitumen, it is laps, blisters and the flashings up walls and curbs. On metal, it is fasteners and their washers, panel laps, and any flashing at a headwall or a curb added later. On a coated roof, it is the details — the places where movement concentrates and the coating was applied thin. On every one of them, the drains are worth checking first, because a blocked drain turns a small failure into a pond over it.

What can you do today, and what has to wait?

Stabilisation and permanent repair are different work. If a roof is taking water in a storm, the immediate job is to stop the interior damage — dry-in the failed area, clear the drains, protect what is below — and that can often be done in conditions where a permanent repair simply will not bond. Membrane and coating repairs need a dry, clean substrate and a temperature window, so we come back and do the real repair properly rather than smearing mastic in the rain and calling it finished. We will tell you plainly which one we are doing on the day.

What do you hand over when the repair is done?

A short report you can file: dated photographs of the failure, of the work in progress and of the completed detail, the location marked on a roof plan, a description of the cause rather than just the symptom, and a recommendation — this detail is now sound, these three other details are heading the same way, this roof needs a survey before next summer. Facility managers need that document for the building file and for warranty compliance, and owners need it because it is the only record that turns roof spending into an asset history rather than a series of invoices.

When do repeated leaks mean the roof is finished?

When the failures stop being events and start being a pattern. Three signs matter more than the roof's age: leaks appearing in new locations each season rather than recurring in the same one; a membrane that has become chalky and brittle, so patches no longer bond reliably; and a moisture survey that finds wet insulation across a meaningful share of the field. At that point every repair is money spent on a roof you are still going to replace, and the right conversation is whether it is a restoration or a replacement.

How do we stop paying for the same leak twice?

By putting the roof on a schedule instead of a fire alarm. Most of what we repair in an emergency was visible months earlier as a lifting seam, a blocked drain or a split boot, and would have taken ten minutes to fix on a routine visit. A maintenance agreement covers exactly that: semi-annual walks, drains cleared, details checked, small repairs made on the spot, and a photo report each time — which is also the documentation most manufacturer warranties require you to be able to produce.
