Commercial wind damage roof repair in McKinney, TX: lifted edge metal, torn membrane and shifted equipment secured, dried in and repaired to a written boundary.
Tell us about the building and what you are seeing. We reply with the next practical step.
A loose coping cap on a windy afternoon can become a falling object over a loading dock, so the first check after a gust event is what could leave the roof next. In McKinney, TX, that check comes before any estimate. We walk the perimeter, secure what is moving, and cover openings where water could reach the occupied floor. Only then do we decide whether the repair stays inside a contained boundary or grows into a larger scope.
Spring is the weather service's severe-weather peak for the Dallas-Fort Worth area, and damaging wind is on its list of hazards. That regional pattern does not tell us what happened on a specific roof. The inspection does, and the written findings belong to the building, not to the weather report.
Wind finds the edge before it finds the field. Coping, edge metal, parapet flashing and the termination along a wall are the first parts to loosen. Next come corners of the membrane, where uplift forces are highest, and rooftop equipment such as vents, hoods, antennas and light-gauge ductwork. We inspect each of these in that order.
Inside the field, we look for fluttering. A membrane that billows and drops under repeated gusts can pull out fasteners in a line, tear at a seam, or lift the adhesive bond in a strip. Ballasted roofs can lose stone and expose the sheet. Metal roofs can lose a panel, a clip line or a trim piece. Each of these failures has its own signature, and we photograph it before moving anything.
The goal is a short list: what is torn, what is loose, and what is still sound. That list sets the repair boundary. Everything inside it is replaced or reattached to the assembly's detail. Everything outside it is checked, but left alone.
Isolation comes first. We close the work zone below the damaged area, route traffic away from the building edge, and confirm who holds the roof key. If an occupied shift is running, the facility director names the production areas that stay open, and the lift and staging area go where trucks and forklifts can keep moving.
The temporary cover goes on next. Tarps are fastened to the deck or curb, not to the damaged membrane, and edge metal is secured with temporary clips until the permanent piece is ready. Sealed patches go over small tears. Each temporary measure is photographed and logged so that nothing remains unrecorded when the permanent repair begins.
Where wind has displaced rooftop equipment, the mechanical contractor is brought in to reset or secure it before we flash around it. Our emergency roof repair response covers the first visit at any hour, and the closeout record starts with the arrival time.
A repair boundary is the line between the new work and the old roof. It has to land on sound material, not on membrane that is brittle or wet. We probe beyond the visible damage, test the bond of the surrounding sheet and, where moisture is possible, use an infrared moisture survey to map the insulation underneath.
If the old membrane will accept a weld or an adhesive, the patch ties in at a clean edge. If it will not, the boundary moves outward until it does, or the section is cut out and replaced. A patch laid over weak material tears again in the next storm, and the owner pays twice.
Edge metal needs its own detail. We use continuous cleats, sealed joints and fasteners that reach the substrate, matching the manufacturer's requirement or the code in force. The building official can confirm which parts of the 2024 International Building Code, as amended in McKinney, apply to the scope. We raise that question early so the permit path does not slow the repair.
Welded seams and adhesives need dry surfaces. A thunderstorm cell moving through Collin County can end the day's work in minutes, so we size the scope to what can be closed before the next weather hold. Anything left open is covered and photographed.
Heat changes the timing too. NWS normals for Dallas-Fort Worth list average July and August highs near 96 degrees, and dark roofing gets far hotter than the air. Crews work early, rotate on a schedule and avoid handling membrane in the peak afternoon hours. Hot membrane stretches and is harder to weld cleanly.
On a multi-building site along US 75 or the SH 121 business districts, we schedule by building, not by day, so that a rain delay at one roof does not idle the whole crew. The facility director sees a short status each afternoon: what is dry, what is covered and what is next.
The permanent repair follows the assembly. On TPO and other single-ply roofs, torn sheet is cut back to sound material, fastener rows are rebuilt and the patch is welded, then probed. On a fully adhered system, the substrate is cleaned and a bonded patch or section replaces the peeled area. On a ballasted roof, the stone is restored to the specified weight after the membrane is repaired.
Standing seam and other metal roofs need panel resets, clip checks and sealant replacement at seams. Where a panel is bent beyond reuse, a new piece is formed and tied in. On modified bitumen, torn plies are cut out and rebuilt with compatible sheet, then flashed back to the wall.
When wind damage is widespread or the membrane is aged, a larger conversation about replacement belongs in the written scope, with the evidence next to it. If a roof leaks again at a new opening, flashing failure is often the cause and gets its own repair.
At closeout, the owner receives photographs of the damage, the temporary protection, the repair and the finished surface, plus a diagram of the repair boundary and the materials used. A return visit after the next significant storm confirms that the work held.
For facility teams running several buildings, the record feeds a multi-site roof program. Properties in Allen or Frisco can use the same format. Hail often arrives with the same spring storms, and the hail damage process shares much of the documentation.
Share where the roof is damaged, your operating hours and the roof access route. We will secure the roof, then sequence the repair around the building's workday.
Short answers to what owners and facility managers ask before a roof visit.
Keep people clear of the roof edge and the ground below it. Photograph the damage from the ground and from inside. Send us the roof access route and the key holder. Do not try to tie down loose pieces yourself.
A temporary cover can go on any day conditions allow. The permanent weld or bond needs a dry surface and workable temperature, so we schedule it for the next clear window.
By the pattern. Fresh tears, clean metal at lifted edges and displaced debris point to an event. Dry, cracked sealant and shrunken membrane point to age. We photograph both and record what we see.
Sometimes only the cap and cleats need resetting. If the substrate is rotted or the cleat is undersized, the edge is rebuilt. We check the termination before we choose.
It will match in function. We use materials compatible with the existing system. Color and weathering may differ at first, and the product data goes in the closeout file.
