Water through a ceiling grid can shut down a suite, ruin inventory or close part of a warehouse. Our commercial roof repair work is one part of commercial roofing in Irving, and it is built around two goals: stop the water now, and fix the cause so it does not come back after the next storm.
Commercial roof leak: where is the water getting in?
On a low-slope roof the drip inside is rarely below the hole outside. Water runs under the membrane or along a deck flute before it finds a seam in the ceiling. These are the entry points we check first on Irving buildings:
- Flashings at rooftop units and curbs. HVAC curbs, exhaust fans and pipe penetrations move with heat and vibration, and their corners open first.
- Parapet and wall flashing. Base flashing pulls away from parapets as it shrinks and hardens in summer heat.
- Seams. Split laps on modified bitumen, unwelded or peeling seams on TPO, and opened laps on metal panels.
- Drains and scuppers. A clogged drain or undersized scupper backs water up over flashing that was never meant to sit underwater.
- Punctures. Foot traffic from HVAC service, dropped tools and hail all leave small holes that only show when it rains.
Standing water makes every item on this list worse, because it keeps pressure on seams and flashing until they soften or open. Irving's May downpours and the 33 to 37 inches of rain the city sees in a year test drains hard.
Emergency commercial roof repair: stopping water first
When a leak is active, we start with urgent temporary repairs: clearing drains and scuppers so standing water can leave, sealing open seams, placing temporary patches over punctures, and covering failed flashing. If the leak is above equipment or stock, we tell your staff where it is coming in so they can protect what is below. The temporary work is not the repair; it buys time for a dry day to fix the roof properly.

Flat roof leak repair on commercial membranes, built-up and metal
Each roof system has its own repair method, and mixing materials is how patches fail.
TPO and other single-ply membranes
Seams are cleaned, prepared and heat-welded with a hot-air welder; punctures get a welded patch of matching membrane. Older TPO that has chalked or cracked may not accept a weld, and we test before promising one. Our TPO roofing page covers the membrane in more depth.
Modified bitumen and built-up roofs
Blisters are cut open, dried and patched with compatible ply and surfacing. Cracked base flashing at parapets is stripped and replaced, not coated over. On gravel-surfaced built-up roofs we scrape back the gravel, repair the plies and set the surfacing again.
Metal panel roofs
Leaks usually trace to worn fastener washers, open side laps, failed ridge closures or curbs cut into the panels. We replace screws, reseal laps and rework curb flashing.
What our commercial roof repair in Irving includes
A commercial repair is scoped by area and by detail, not by the size of the stain inside. Before we cut into anything, we identify the roof system, check that the membrane will still accept a patch or weld, and look at the insulation around the leak: wet board has to be cut out and replaced, or the repair traps water that keeps rotting the deck. If your roof is still under a manufacturer warranty, we read the warranty terms first, because some require specific repair methods. The scope below is what a typical visit covers, and the written summary at the end gives an owner or property manager a record to keep with the building file.
- a walk of the roof and, where needed, the interior below the leak
- photos of every defect, marked on a simple roof plan
- urgent temporary repairs if water is entering
- the permanent repair, using materials compatible with your existing roof
- drain and scupper clearing in the repaired area
- a short written summary of what we fixed, what we saw nearby and what can wait
How a repair visit runs
- Call and triage. You tell us where water is showing and what is underneath it, and we ask about roof access.
- Find the source. We walk the roof from the leak location uphill, checking seams, flashings and drains, and probe suspect areas.
- Stop the water. If it is raining or more rain is coming, temporary repairs go in first.
- Make the permanent repair. On a dry day, we cut out and replace damaged material and reflash where needed.
- Water-test where possible. Where a hose test is safe and useful, we run water over the repair.
- Report. You receive photos and a summary you can pass to an owner, tenant or insurer.
Warehouse roof repair in Dallas and Irving: what does it cost?
We do not post repair prices, because a single curb flashing and a dozen split seams across a 100,000-square-foot warehouse are different jobs. Repair cost depends on how many leak points there are, the roof system, how hard the roof is to reach, whether insulation below is wet and has to be cut out, and whether temporary work comes first. We give a free estimate after the inspection, and if a repair is not the sensible spend, we tell you. When repairs keep stacking up, compare them against commercial roof replacement before the next budget cycle.
Three Irving conditions tend to move a repair estimate. Ponding areas often need more than a patch: a cleared drain, a cricket or a tapered insulation fix may be what keeps the repair from reopening. Roofs that baked through a 95°F July can be brittle enough that seams must be cut back further before new material will bond. And after a hailstorm, punctures are rarely alone, so we grid and photograph the whole field before pricing.

Permits, registration and code checks for commercial repairs in Irving
Texas does not license roofing contractors, and TDLR has no roofing program, but the City of Irving requires annual contractor registration and a permit for larger roof work; our written estimate states who applies for that permit before work begins. Small spot repairs usually fall under the threshold; once a repair grows into replacing a section of membrane and insulation, the city may treat it as roof replacement work. At that point two local rules can apply: the energy code's insulation requirement for replaced roofs with insulation above the deck, and the SRI 78 cool-roof minimum for low-slope roofs in Irving's Chapter 8B amendments. We confirm with the Inspections Department, (972) 721-2371, before quoting. On a hail claim, Texas Insurance Code Chapter 4102 lets only the owner or a licensed public adjuster negotiate with the insurer.
