Commercial Roof Repair in Rowlett

Home / Service Areas / Rowlett

One of the most common calls we get in Rowlett is about a leak that keeps coming back. Somebody patched it last year, and maybe the year before that. Each time it held for a while, then started dripping again. That usually means the patch is treating a symptom while the real problem is somewhere else, or the patch material does not match the roof underneath.

We also serve Garland and Rockwall. When a leak returns, we start by looking at what was done before, then find and fix the actual cause.

Rowlett's location on Lake Ray Hubbard means wind-driven rain is common, and it finds weak flashing and seams that ordinary rain never reaches. That is one reason a leak can seem to come and go with the weather.

Look at what was done before

Before we add another patch, we look at the old ones. What material was used? Is it bonded to the roof, or just sitting on top? Is it in the right place, or is the water coming in somewhere nearby?

For a commercial roof leak repair on a repeat leak, we also ask your team for history. When did the leak first appear? When was it patched, and by whom? Does it get worse with certain weather, like wind-driven rain from one direction? Invoices and photos from earlier repairs help a lot.

Often we find that the original leak was at a flashing or seam a few feet from where the patch went, and water traveled along the deck before it dripped. Patching where the water shows up inside, rather than where it gets in, will never solve the problem.

We test our theory before committing to the repair, using a controlled water test if needed.

Fix the defect, not just the symptom

Once we find the real defect, we fix it with materials that match the roof. On a TPO roof, that means cutting out failed material, cleaning the existing TPO and heat-welding new membrane or flashing to it. Each weld is probed once it has cooled.

Repeat leaks often involve incompatible patches. Asphalt mastic, general-purpose caulk and some peel-and-stick tapes do not bond to TPO. They may seal for a while, but heat and movement break them loose. We remove them completely before installing a proper repair.

We also look at why the defect happened. A seam that keeps opening may be under stress from a sagging deck or a vibrating unit. Flashing that keeps pulling loose may be too short or poorly fastened. If the cause is not fixed, the repair will fail again.

Each repair is described with its location, the defect we found and the fix we made.

Look under the old repair

Repeat leaks usually mean water has been getting into the roof for a long time. Under the old patch, the insulation is often soaked. The deck may be rusted or soft. A new patch on top of that will not last.

We cut open the area and check. Wet insulation gets replaced. Damaged deck gets shown to you before we go further. If the wet area looks bigger than the repair, a roof condition report or infrared scan can map how far the water has spread.

We photograph everything before it is covered. Extra work is priced and explained before the crew does it.

This step is where many repeat-leak repairs go wrong. Patching over wet insulation traps the water, and the leak comes back. Taking the time to open it up is what makes the repair last.

Plan around people in the building

Most Rowlett commercial buildings stay open during roof work. On an office building, we ask about tenant hours, parking and any noise limits. We schedule loud work, like cutting out old material, for times that will disturb the fewest people.

Repeat leaks are often near equipment openings: HVAC units, exhaust fans, plumbing vents. If a repair involves equipment, we coordinate with your mechanical contractor. A unit may need to be shut down, disconnected or lifted while we replace the flashing underneath.

We also check air intakes near the work area. Cleaning solvents and adhesives can have odors that get pulled into the building. We work with your HVAC contractor to protect intakes while we work.

Before starting, we agree on the access point, staging area and how debris is removed.

If the leak is over a tenant space, we may need to check the ceiling from below, and we arrange that through your property manager.

Explain the cost and the result

Our price for a repeat-leak repair includes finding the real source, removing old patches, replacing wet insulation if found and installing a proper repair. If we find more damage than expected, we stop and explain it before continuing.

When the work is done, you get a report: the history you gave us, the source we found, the old patches we removed, any hidden damage and the finished repair, with photos of each stage.

The report also explains why earlier repairs failed. That is useful for your records, and it can help you decide which contractors to call in the future.

If the leak is part of a bigger pattern, such as aging seams across the roof or widespread wet insulation, we tell you. A larger repair or a planned replacement may cost less over the next few years than chasing leaks one at a time. We price those options side by side so you can compare.

And if the leak ever returns after our repair, we come back and track down the reason.

Commercial Roofing Questions

What should we tell you about a leak that keeps coming back?

When it first appeared, when and how it was patched, what weather makes it worse and any invoices or photos from earlier repairs.

Can the same patch just be repeated?

Usually not. Repeat leaks mean the patch is in the wrong place, uses the wrong material or is sitting on wet insulation. We find the real cause first.

How does hidden damage change a repair?

Wet insulation and damaged deck under an old patch have to be fixed before the new repair goes on. We photograph them and explain the cost first.

What coordination is needed when the leak is at an equipment opening?

Your mechanical contractor may need to shut down, disconnect or lift the unit so we can replace the flashing underneath. We arrange that before the work starts.
