Commercial Roofing in Dalworthington Gardens

Commercial roof seam repair in Dalworthington Gardens, TX: EPDM seam inspection and repair, wet insulation checks and labeled photos of the work under the finished seam.

Dalworthington Gardens is a small city surrounded by Arlington, and its commercial roofs face the same North Texas heat, hail and wind as everyone else's. On EPDM rubber roofs, the seams are often the first thing to go. The adhesive or tape that holds two sheets together dries out, the edge lifts and water works its way in. We inspect the seams, find the ones that have failed and repair them so they hold.

We also repair roofs in Pantego and Kennedale, and every building gets its own inspection.

We walk the seams in the area of concern and check each one. A probe or blunt tool run along the edge shows where it has let go. We also look for fishmouths, wrinkles where the seam has opened, and old patches that may be peeling. Each failed section gets marked on a roof plan and photographed.

Our seam failure repair estimate lists each failed seam, how long it is and how we will fix it. If a tenant reported a leak, we note whether the failed seam lines up with the leak. If it does not, or if there could be another source we could not reach, we say so. One repaired seam does not always mean the leak is gone.

We also check seams near the failed ones. If one seam has let go, the ones beside it are often the same age and close behind.

Seam failures tend to show up in a few predictable places: at T-joints where three sheets meet, around penetrations where the roof was cut and patched, and along seams that get walked on during HVAC service. We pay extra attention to those spots, because a seam that looks fine from a standing height can be open underneath. Where we find a pattern, such as every T-joint on one side of the roof lifting, we note it so you can see whether the problem is isolated or spreading.

A seam repair only lasts if the new material bonds to good membrane. We check the EPDM next to each failed seam for chalking, shrinkage and brittleness. If the rubber is still flexible and cleans up well, it is a good base. If it is cracked or will not take primer, we cut back until we reach sound membrane.

For EPDM roofing, we clean the seam area thoroughly, prime it and apply seam tape or a cover strip made for EPDM, then roll it down firmly. Old seam adhesive, dirt and oxidation all have to come off first, or the new tape will not stick.

If an old repair used an incompatible material, like a roofing cement that does not bond to EPDM, we remove it before making the new seam.

Weather matters for EPDM seams too. Primer and tape need a dry, reasonably warm surface to bond well, so we schedule seam work around rain and early-morning dew. A seam taped onto damp rubber may look fine the day it goes down and start lifting a few months later.

A seam that has leaked for a while usually wets the insulation underneath. That insulation stays wet under the membrane, loses its R-value and can rust a steel deck. If we see soft spots, blisters or get high moisture readings near a failed seam, we cut a core to check. Wet insulation is replaced before the seam is closed.

On an office building roof, we set up core cuts and any openings with the building manager, since tenants below may hear the work or need notice. The core result applies only to that spot. If other areas look suspect, we test them separately.

If we open the roof and find more than expected, such as a larger wet area, rotted wood blocking or a rusted deck, we photograph it and talk with you before going further. You see the updated price before we go on.

Seam repairs follow a set order. First, any wet insulation and damaged deck get replaced. Then old patches and incompatible materials come off. Then we clean and prime the existing EPDM along the seam. Finally, the new seam tape or cover strip goes on and gets rolled in. If anything keeps the new seam from bonding, such as brittle membrane or a stubborn old repair, we deal with it first and list it in the estimate.

We confirm roof access, parking, material staging and work hours with the building contact. If an HVAC contractor needs to move or reset a unit sitting on a failed seam, that goes on the schedule before our work.

We keep you updated on each step, so you know when the repair is actually done and not just when the last seam looks finished.

When you call about a Dalworthington Gardens building, tell us which part of the roof is leaking or looks worn, how old the roof is and who can let us up. Past repair invoices help too, because they tell us what has already been tried. We will inspect the seams, mark the ones that have failed and send an estimate that shows the repairs, the insulation work and anything else that needs to happen first. If you see a lot of failed seams, it may be time to talk about replacement instead of repair, and we will tell you if we think that is the case.

Those records also help with warranties and insurance. If a manufacturer warranty is still active on the roof, the photos show the repair was made with compatible materials. If hail or wind becomes part of a claim later, you have dated photos of the seams before and after the repair.

We photograph each step: the failed seam as found, any opened insulation, the cleaned and primed membrane and the finished seam. Each photo is marked to its location on the roof plan. A photo of a new seam shows the finished surface; the photos of the prep show the repair was done right.

A roof condition report for a Dalworthington Gardens building lists every seam we repaired, every seam we found starting to fail but did not repair, and any part of the roof we did not inspect.

If we put a temporary patch on a seam before the permanent repair, the report says so. That record helps you plan the next round of maintenance.

Can you tell the condition of our roof from the address or records alone?

No. Records help us know what to look for, but we have to inspect the actual seams on the roof before recommending a repair.

If you fix the failed seam, will the leak stop?

Usually, if the seam lines up with the leak. If there could be another source we could not reach, we say so in the estimate and report, so you know what was and was not checked.

Why does the repair need to reach good membrane?

Seam tape only holds if it bonds to clean, flexible EPDM. If the rubber next to the failed seam is brittle or cracked, we cut back until we reach sound membrane.

How do you decide whether to replace insulation under a seam?

We cut a core where we see signs of moisture. If the insulation is wet or crushed, it gets replaced before the seam is closed. A dry core stays in place.

What photos will we get of the seam repair?

Photos of the failed seam, any opened insulation, the cleaned and primed membrane and the finished seam, each tied to its location on the roof plan.

Tell us where the leak or worn seam is. We'll inspect the seams, check the insulation underneath and send you a clear estimate for the repair.
