Repair punctures, gouges and foot-traffic wear on McKinney commercial roofs with matched patches, walk pads and a closeout record of every service route.
Tell us about the building and what you are seeing. We reply with the next practical step.
A dropped screw, a ladder foot or a service technician's boot heel can open a membrane in a second, and the leak that follows may show up weeks later at a ceiling tile far from the hole. In McKinney, TX, where office and industrial parks and retail districts all put equipment on roofs, the traffic never stops. We start by tracing the path technicians use from the hatch to each unit, because wear and punctures cluster along it.
The first check separates cosmetic scuffing from an opening that lets water in. A scuff stays on the surface. A puncture goes through the sheet, and water that gets under it spreads through the insulation where nobody can see it.
The city describes office and industrial parks across McKinney alongside its retail districts, so one portfolio can include roofs with very different traffic. A warehouse roof with two units sees a few visits a year. A retail roof with kitchen exhaust, cooling units and signage sees a steady flow, and the repair plan reflects.
The inspection follows the route. We begin at the roof hatch or ladder and walk toward each unit, noting scuffs, gouges, punctures and abrasion. Wear concentrates along the straight line from door to equipment, at turns and where people step off a ladder. Each mark goes on a roof diagram with a photograph and a scale.
We look beyond the visible hole. A puncture near a seam may have opened the lap. A gouge across a reinforcement layer may have exposed fabric. A mark near a drain may have damaged the flashing. We probe the area and check surrounding membrane for blisters, softness and rippling, which suggest water beneath.
If water may have gotten in, an infrared moisture survey outlines the wet insulation around the damage. A small repair in a wet area will fail, so the insulation is dried or replaced first. Even a minor puncture can reach farther under the membrane than it looks from above.
Hidden damage turns up when equipment is replaced. The membrane under a removed unit may carry gouges from its feet or from dragging, and the curb area may be worn from years of service. We check the footprint of any removed unit before the new one is set, and repair the surface while it is open and easy to reach.
The lasting fix for foot-traffic damage is to give traffic a place to go. Walk pads along the routes to equipment take the wear that would otherwise land on the membrane. They cost little compared with the repairs they prevent. We bond or weld them where the diagram shows heavy use so they do not shift.
Trade rules help. Every contractor who goes on the roof should know the paths, the no-walk areas and the duty to report damage. We provide a simple roof access sheet for the building: where the hatch is, where to walk, what to avoid and whom to call. Tools and parts left on the surface cause punctures, and the sheet says so.
Access for service units deserves planning. Where technicians reach a unit often, a platform or a ramp over low obstructions prevents trips and damage. Our work on curbs and penetration flashing includes those transitions.
Ladders and hatches create their own damage. A ladder leaned on a parapet scrapes the coping and crushes the flashing, and a hatch that slams can crack the curb sealant. Ladder pads, hatch dampers and a marked landing zone protect those spots.
A few isolated punctures call for spot patches. A cluster of damage in a high-traffic zone may call for a section repair, replacing worn membrane with new sheet and adding walk pads. Roof-wide damage, such as impact pitting or widespread abrasion, may call for a recover or coating.
We lay out the options with their limits. A patch is quick and inexpensive, but it adds a seam. A section repair costs more and lasts longer. A coating can protect a worn surface if the membrane is sound underneath. When damage is widespread and the membrane is old, a recover may be worth pricing, since repeated patching eventually costs more than renewal.
The repair boundary lands on sound sheet. The patch extends well beyond the damage with rounded corners so edges do not lift. We clean the area, remove dust and oil, and prepare the surface to the manufacturer's requirements. After installation we probe the edges and test the bond.
Heat affects patch work. Sun-baked sheet runs hotter than the air, and July and August highs near 96 degrees make it worse. Hot sheet is soft and hard to weld, and adhesives can skin over before they bond. We schedule patches for the morning and rotate crews on large jobs.
Spring storms are the other constraint. Spring is the other constraint, since hail and wind season peaks then across the Metroplex. A hail event can leave punctures of its own, and we document them separately from foot-traffic damage.
A weather hold is built into every plan. If the forecast turns, openings are covered and the repair waits. On sites along US 75 or the SH 121 districts, we coordinate with tenants so a hold does not strand a lift or block a dock.
The patch has to bond to what is there. On thermoplastic roofs, a cleaned and heat-welded patch of the same material fuses to the field sheet. On rubber roofs, a primed patch with adhesive or tape forms the bond. On modified bitumen, a compatible sheet is adhered or heated into place. On built-up roofs, new felts or a modified patch go over a cleaned surface. Mastic and sealant are not substitutes for a proper patch, and they fail quickly on a moving surface.
On aging roofs, a patch may not bond. The surface may be too hard or weathered. We test a small area first, and if it fails, we use a larger patch or recommend a more extensive repair. A commercial roof repair scope states which approach applies.
If the puncture came with a displaced seam, the seam is repaired in the same boundary. If it followed a hail strike, the process for hail damage applies to the whole struck area.
We keep a log of every repair: location, date, cause, method and photograph. Over time the log shows where damage keeps happening and what to change. If punctures cluster at one unit, a walk pad or platform fixes the pattern.
A scheduled maintenance visit after trades have been on the roof catches new damage early. Owners with several buildings can add this to a multi-site roof program. Properties in Frisco or Allen follow the same log format.
Tell us which units need regular service, your operating hours and the roof access route. We will map the wear and sequence the repair around the building's workday.
Short answers to what owners and facility managers ask before a roof visit.
Yes. A small hole lets water into the insulation, where it spreads and stays. The patch is quick and inexpensive. Wet insulation and interior damage cost far more.
The contract and lease decide. A dated photograph and a condition report help the owner show when the damage happened. We document and repair it.
Only along heavily used routes. Wear follows the line from hatch to equipment. We place pads there, at turns and at step-offs.
As a temporary measure, yes. Permanently, rarely. Sealant does not bond well to a moving membrane. A matched patch lasts much longer.
Give them a roof access sheet, mark routes with pads, and require that tools and parts leave with them. A roof check after service catches anything missed.
