Seam Failure Roof Repair in Arlington, TX
Seam Failure Roof Repair
Seam failure roof repair in Arlington, TX: identify the membrane, cut back to sound material, check for wet insulation and close out the seam ends properly.
The February 14-17, 2021 winter storm hit North and Central Texas, and some owners first noticed open seams on their Arlington roofs in the months after. Whatever opened it, a lasting repair means joining compatible material to clean, sound membrane. An open seam is where the inspection starts, and the condition of the membrane around it, plus whatever is underneath, decides how big the repair really is.
Commercial Roofing Services Arlington looks at each seam failure in light of the membrane actually on your roof. We find the open section, check the membrane on both sides, and explain what prep is needed before the seam can be rebuilt. If the damage runs past the open joint, it goes in the estimate. Patching the same narrow strip again, on top of membrane that can't hold a bond, usually means paying for the same leak twice.
First, identify the membrane
Before we pick a repair, we confirm what the roof is and how its seams were made. TPO and PVC seams are heat-welded; EPDM seams are taped or glued. They aren't interchangeable just because both roofs have seams. Old installation records help, but if there's any doubt we confirm the material at the repair spot. Earlier patches or coatings can also change the surface the new seam has to bond to.
A TPO roof seam needs cleaning and prep suited to TPO and its age. An EPDM seam needs a different method entirely. We name the actual repair procedure and the surface it needs, rather than treating one all-purpose sealant as the answer for every roof. If we can't confirm the membrane, we settle that question before ordering material for the permanent fix.
Cutting back to sound membrane
We check the membrane on both sides of the open seam. The new seam needs enough clean, sound material to bond to. Dirt, chalky or worn membrane, shifted sheets, or an old patch made with the wrong product can push that starting point further out. When the repair has to reach past the visible split, we explain why. A price to bridge just the gap may be less work than a fix that actually reaches good membrane.
The estimate shows where the repair starts and stops and how it ties into the existing roof. If something nearby can't be reached or seen yet, we note it and say what still needs to be checked. We won't call a repair ready to install while the membrane it has to bond to is still a question mark. You should be able to tell an inspected repair apart from a number resting on membrane nobody has looked at.
Checking under the open seam
An open seam is a good reason to check for water underneath, but it doesn't tell you how far the water went. If wet insulation would change the repair, we test for it. An infrared moisture survey can help us target where to look on the right kind of roof. The readings still have to be read alongside how the roof is built and the conditions during the scan, not taken as proof of what every layer looks like.
If core cuts confirm wet or crushed material, we may need insulation and cover board replacement under the new seam. We mark how much comes out and check the deck once it's exposed. A bad deck, or anything that needs an engineer's review, gets dealt with before we close the roof. Openings need protection below, your approval and proper patching. If what we find changes the plan, we talk with you before making the opening bigger.
Where the seam ends
Many failed seams run into a curb, a wall, a drain or an old patch. We check that end point separately from the straight run of seam. A flashing failure repair may need new backing at the wall or prep work on a curb. A good weld along the field doesn't fix a loose flashing where the seam stops. We show how the repair closes each of those ends.
Membrane puncture repair nearby may need its own repair area, even if the punctures have nothing to do with the seam failure. We mark those spots and tie each repair to what we actually found. If several repairs overlap, we explain the order of work and anything another trade has to do. That lets you weigh a complete repair against a quick seam price without missing the work around it.
Seam repairs around Arlington
Knowing a leak is in Downtown Arlington, the Great Southwest Industrial District or the South Cooper Street Corridor helps us place the request, but we still need the actual address and which roof section is leaking to set up a visit. Work in our Downtown Arlington service area is planned for that specific building, and its membrane and seams have to be inspected. Knowing the neighborhood doesn't tell us the roof system or give us access to the rooms below.
We'll ask for any installation records, where and when leaks have shown up, and who can let us onto the roof. We identify the space under any planned opening and what protection it needs. Material deliveries and torn-off membrane need an agreed route, too. If extra removal moves the work over a different occupied area, we review that with your building contact before going on. The seam repair and the protection below are planned as one job.
A good seam inspection sorts out why the seam failed: a weld or bond that never took, dirt in the lap, building movement, heat damage, or an earlier repair made with an incompatible product. We identify the membrane and seam type, then probe or open the seam using the method that fits that system. The repair extends to clean membrane that can take the new lap, and it includes any flashing or transition where the seam ends. If water got under the sheet, we keep that insulation question separate from the seam repair itself. The estimate names the prep, the patch or splice method and how many feet of seam we're fixing. We photograph the seam before work and the finished seam after it has cooled or cured. That gives the next inspector a clear reference point instead of judging the repair by how it looks on top.
Recording the finished seam
We keep photos of the original split, the sound membrane we tied into and any insulation or cover board we replaced. Anything we find under the membrane gets photographed before new material covers it. The finished seam is checked with the method that suits that roof, such as probing a heat weld. The record notes what we actually built and any nearby detail still open. A clean-looking strip of new membrane can't show the prep under it, and it doesn't prove there isn't another leak somewhere else.
If the repair changes from the first estimate, the record keeps what we found and who approved the change. You'll know which area got bigger and why. Any correspondence with or sign-off from the membrane manufacturer is kept apart from our own completion notes. With that history, the next inspection starts from facts instead of guessing at the repair from a patch on the surface.
Temporary repairs are recorded separately from the permanent seam. If one stays in place while another trade finishes its part, the record names that work and who is handling it. Your roof file should make it easy to tell what's finished and what isn't.
Common Questions
Can the same repair method be used on rubber and thermoplastic seams?
No. EPDM rubber seams are taped or glued, while TPO and PVC seams are heat-welded, and each needs its own prep. We confirm the membrane, and any coating or old patch on it, before choosing the repair.
Why might the repair need to be wider than the visible split?
The new seam has to bond to sound membrane. Worn or dirty membrane, or damaged material underneath, can mean cutting back further. We show you what we found and where the repair ends, so you can compare it with a price that only spans the gap.
Does an open seam mean the insulation under it is wet?
Not necessarily. It's a reason to check, and we test with core cuts where wet insulation would change the repair. We tell you what we tested and what we didn't, rather than guessing at a wet area or calling the whole roof dry from one look.
What should be checked at the ends of a repaired seam?
Where the seam meets a wall, curb, drain or other detail. Those spots often need their own flashing work or prep before the seam repair can be closed. A good weld along the field won't stop a leak at a loose end.
