Commercial Roofing in Pantego

Commercial roof flashing repair in Pantego, TX: we find the failed flashing at walls, curbs and penetrations, weld new PVC to sound membrane, fix rotted backing and photograph the work.

Pantego is a small town tucked inside Arlington, and many of its commercial buildings are offices, shops and medical suites with low-slope roofs. When those roofs leak, the cause is very often flashing: the membrane that turns up a wall, wraps a curb or seals around a pipe. Flashing takes more movement and heat than the flat part of the roof, and it is usually the first thing to pull loose. We find the failed flashing, check what is behind it and repair it so it stays put.

We also repair flashing on roofs in Dalworthington Gardens and downtown Arlington, and every building gets its own inspection.

We start with the leak or the problem you have noticed, then walk the flashing in that area: at parapet walls, rooftop curbs, pipe penetrations, skylights and roof edges. We look for flashing that has pulled away from the wall, corners that have split, counterflashing that is loose or missing, sealant that has dried and cracked, and pitch pans that have emptied out.

Our flashing failure repair estimate lists each failed spot with a photo and its location on a roof plan. We also check what the flashing attaches to. If a wall has cracked mortar, a stucco parapet is letting water in from above, or a curb is rotted, the new flashing will not hold until that is fixed. Some of that may be masonry or carpentry work, and the estimate says so.

If a tenant reported a leak near a wall, we check whether it lines up with the flashing. Water can also come through a window, wall cap or cracked masonry, so we note anything we could not rule out. That way nobody assumes the flashing repair took care of every possible source.

New flashing has to bond to the membrane already on the roof. We confirm what system is there and check the sheet where the flashing will tie in. Membrane right at the base of a wall often takes more heat and movement than the rest of the roof, so it may be more worn.

For PVC roofing, we clean the existing sheet, hot-air weld new PVC flashing up the wall or curb and onto the field and probe the welds once they cool. Older PVC can stiffen as it ages, so we run a test weld first. If it will not take a good weld, we cut back to membrane that does. TPO, EPDM or modified bitumen roofs get their own method.

We also check seams near the flashing. If a nearby seam is already open, we fix it at the same time, because otherwise water gets in behind the new flashing.

When flashing has been loose for a while, water gets behind it and soaks the wood blocking, the wall sheathing and the insulation at the base of the wall. Rotted wood will not hold fasteners, so new flashing fastened into it will pull loose again. If we see soft spots, staining or high moisture readings, we open the area or cut a core to check. Rotted wood and wet insulation get replaced before the new flashing goes on.

On an office building roof, we schedule openings with the property manager, since tenants are right below and may need notice.

If we open the area and find more damage than expected, we photograph it and talk with you before going further. A check at one wall tells us about that wall. Other walls or curbs get their own inspection.

Flashing repairs follow a set order. Old flashing and counterflashing come off. Rotted blocking, wet insulation and damaged sheathing are replaced. Any masonry or wall repair by another trade is finished. Nearby seams are fixed. Then we clean and prep the existing PVC, weld the new flashing, install termination bar and fasteners and reinstall or replace the counterflashing. If anything still keeps the flashing from sealing, we tell you what it is and list it in the estimate.

We confirm roof access, parking, staging and work hours with the building manager. Pantego properties are often small, with tight lots, so we plan where the truck and materials go ahead of time. If a mason needs to repoint a wall or an HVAC contractor needs to reset a unit before we can flash it, we name that task and coordinate the timing.

We keep you posted step by step. Flashing that looks finished from the ground is not the same as flashing where every step underneath was completed, so you get a status on each item.

When you call about a Pantego building, tell us which building, where the leak or loose flashing is and who can give us roof access. Photos help, even ones taken from the ground. If you have past repair invoices or warranty paperwork, send them along. We will inspect the flashing and what is behind it, then send an estimate that shows the flashing repair, any backing or insulation replacement and any work another trade has to finish first. If you own more than one building, each gets its own estimate.

We photograph each stage: the failed flashing as found, the opened wall base, any rotted wood or wet insulation, the replaced materials, the prepped membrane and the finished flashing and counterflashing. Each photo is tied to its location on the roof plan. Once the counterflashing is back on, the work underneath is hidden, so the photos are how you know it was done right.

A roof condition report for a Pantego building lists each flashing repair, any wall or curb work still pending and any area we did not inspect.

If we installed temporary protection first, the report says so. That record makes the next visit easier, whether it is a routine inspection or a new leak at a different wall.

What should a Pantego flashing repair estimate include?

The flashing repair itself, any rotted blocking or wet insulation behind it, nearby seam repairs and any wall or curb work by another trade, each listed separately with its location.

How do you know the flashing is causing the leak?

We check whether the failed flashing lines up with where water showed up inside. If water could also be coming through a wall, window or cap we could not check, we say so in the estimate.

Why does the membrane next to the flashing need checking?

The new flashing has to bond to it. If the membrane at the base of the wall is worn or stiff, the weld will not hold. We test it and cut back to sound membrane if needed.

What happens if you find rotted wood behind the flashing?

We photograph it and talk with you before going further. Rotted wood and wet insulation get replaced before new flashing goes on, because fasteners will not hold in rotted blocking.

How will we know the work under the flashing was done right?

Photos of each step, from the opened wall base to the finished counterflashing, tied to locations on the roof plan, plus a written report.

Tell us which building and where the leak or loose flashing is. We'll inspect it, check what's behind it and give you a clear estimate for a lasting repair.
