Versico Roofing in Plano, TX

A welded seam can fail for more than one reason. On Versico roofs in Plano, we separate a seam that didn't fuse properly from membrane next to it that's been damaged. Our recommendation names the product, the prep and the repair, and marks exactly where the problem is. "Seams checked" on an invoice doesn't tell you what the crew actually found or fixed.

For a large public building like the Plano Municipal Center on K Avenue, we'd start with existing roof records and inspect what we can reach. We identify the membrane, find old patches and then plan the repair. The manager gets a recommendation tied to what we found and the specific fix needed at each spot.

Name the membrane being joined

Versico makes EPDM, TPO, PVC and VersiFleece membranes. Its TPO line includes VersiWeld products with heat-welded seams. That's where identification starts, but the roof still needs its own prep and detail plan. We keep the exact membrane name next to the repair proposed at each location.

A commercial roof inspection identifies the membrane and earlier repairs before we plan any seam work. Confirmed product identification is recorded separately from questions about an unknown patch or what's underneath. You'll see where we have enough information to proceed and where more checking affects the choice. Knowing the membrane family isn't a substitute for looking at the actual seam.

Distinguish fusion from damaged membrane

Versico's guidance says hot-air welded seams should be probed once they've cooled, any problems fixed and the repair probed again after it cools. It also says TPO membrane that's been overheated during welding needs an overlay repair, even if the seam passes the probe test. Those are two separate problems: whether the seam fused and whether the membrane around it was damaged by heat.

Our commercial roof repair scope identifies which fix each spot needs. We record the condition and the repair method based on the product instructions. A seam that passes the probe doesn't cancel out scorched membrane right next to it. Both problems are listed in the price, and you'll see how each one is fixed before the area is reported as done.

Develop the retained surface preparation

Where a new patch or flashing meets the existing membrane, we check that surface and any old coating or patch nearby. We review the prep the chosen products call for before setting the repair size. A small hole may have an older patch beside it that also needs attention. Those notes stay with that repair rather than being applied to the whole roof.

A Carlisle SynTec repair can be priced as an alternative, with its own prep for the existing surface. We don't assume a cleaner or primer from one proposal works for the other. If we can't identify a material yet, we note which decision it affects. You'll know what's confirmed and what still needs checking before the repair is priced as complete.

Complete the support behind flashing

We look at each curb, wall or pipe along with whatever the new flashing has to seal to. Rotted backing or a damaged curb is fixed before the roofing goes on. That work is listed separately from the flashing materials, with who does it and when. A clean membrane surface doesn't help if the curb behind the flashing is falling apart.

On a campus with lots of rooftop equipment, such as Collin College's Spring Creek Parkway campus, existing equipment records would help guide the review. Our rooftop equipment curb and support scope covers curb repairs before the membrane flashing is installed. The detail and the material are tied to each curb. You'll see what the roofer preps and what another trade has to fix first.

Compare a developed replacement arrangement

When a replacement is offered next to a local repair, we describe the tear-off and the new base layers. We explain the evidence for keeping any existing insulation and recommend testing where that's still unclear. The new membrane needs a defined fastening and detail plan for your building. A square-foot total won't show how a replacement differs from a repair that keeps the surrounding roof.

A Holcim Elevate system is another replacement option we can compare. Each product keeps its own components and method. We show the prep both options share and what changes between them. If testing changes a quantity, we record why. You compare complete jobs instead of assuming a different membrane name leaves the rest of the work the same.

Preserve the corrected seam findings

We record the membrane and repair products used at each seam and flashing location. The fix for each problem is noted, including heat-damaged membrane repaired next to a weld. Photos of prep and curb work are taken before they're covered. If a finding changed the repair, that stays with the revised work so the closeout matches what was actually done.

For Downtown Plano buildings and across the city, the next inspection can find the repaired areas and the materials used. A later leak or equipment change can be checked against those seams. You'll also see clearly which roofing work is done and which curb or equipment item is still waiting on another trade, instead of a single "all work complete" note.

Commercial Roofing Questions

What Versico product information should be recorded at a repair?

The membrane installed and any old patch materials that affect the repair. Anything we couldn't identify is listed separately from confirmed work.

If a TPO seam passes a probe test, is the repair done?

Not necessarily. Versico's guidance says overheated TPO membrane needs an overlay repair even if the weld passes probing. We record and fix that damage separately.

Why check the prep where a new patch meets the old membrane?

The existing surface and any old coating affect which prep method works. We identify them and set the prep before finalizing the size of the repair.

What has to be checked before installing new Versico flashing?

The curb, wall or pipe itself, its backing and any repair it needs. We confirm who does that work and when before the membrane flashing goes on.

How do you compare a Versico replacement with a local repair?

Each option lists the tear-off, the existing layers kept and the new insulation and membrane, along with any testing questions still open.
