Commercial Roofing
Trailers back to the doors on a timetable, and a roof leak over door 14 does not care what is on it. For a logistics or third-party operator in Edinburg, TX, the roof protects freight that belongs to someone else, and the contract usually says who pays when it gets wet. I begin a logistics roof walk at the dock edge, where a canopy, a door header and a parapet meet, because that is where wind drives rain into the building and where a 3PL's customers are most likely to see a problem.
The roof also sits above the racking, the sprinkler risers and the conveyor that moves product to the dock. Water that passes the membrane often runs along a joist and drops at a column or an aisle end, far from the opening. We trace it back to the roof detail and write the findings so the operations manager, the landlord and the customer's risk team can all read the same photographs.
A high-bay building has a long, open ceiling and a lot of roof-to-wall transitions. Water that enters at a parapet drops down the wall inside and soaks the bottom pallets. Water that enters at a seam travels along the deck and drips at a rack upright. Water from a skylight curb lands on whatever is below, and in a sorting area that may be conveyor or a staging lane.
We follow the stain backward to the nearest seam, curb, penetration or wall tie-in, then check the rest of the bay for the same detail. Moisture readings and an infrared moisture survey show the extent of wet insulation, which sets the repair boundary. The result is a repair that closes the entry point and a record the operator can share with the customer whose product was nearby.
Large low-slope roofs sit in sustained surface heat through the Valley's May-through-October heat-safety months, and they run hot, and a building full of palletized goods holds that heat. Seams, sealants and flashing laps work through the daily swing, and rooftop units and exhaust fans add curbs that each carry their own flashing.
The Valley's hurricane season of concern runs from June through October. Dolly's winds ran 50 to 70 mph over the county and did minor damage, and in July 2020 Hanna brought wind and flooding to Edinburg. Once the weather clears we check parapet caps, edge metal, rooftop equipment, flashings and drains, because a blocked scupper over a dock canopy turns heavy rain into standing water. A drain and scupper repair is a small job that protects a large floor.
Dock-heavy buildings fail at the edges, and the first sign is often a damp wall base inside, not a roof stain. The long wall with many door openings sees wind and rain on every parapet, and the roof edge above each door carries a gutter, a coping or a drip edge that has to be tight. Forklift traffic and truck impacts loosen canopy attachments. Trailer exhaust and idling add heat and soot to the surface near the dock.
Inside the building, we look for damp patches on the slab at the bottom of a wall, rust on a rack base and water marks at a ceiling joint. Outside, we look for lifted coping, split sealant and ponding at the dock edge. A coping and edge metal repair often stops a recurring dock leak before a membrane replacement is needed.
We walk the roof in bays that match the dock doors, so a finding can be tied to a door number the operator already uses. Each bay gets photographs of the parapet, canopy attachment, seams, drains and any penetration, with notes on ponding and debris. Rooftop units, exhaust fans and skylights are recorded on a plan that shows their curbs and condition.
The written report ranks bays by what sits below them: fast-moving freight, customer-owned product or empty floor. It also lists drains that need cleaning before the storm season and flashings that should be sealed now. A dated record like this is useful in a customer audit and at a lease renewal, because it shows the operator has been watching the roof on a schedule.
It can be done, but the sequence has to respect volume. We work with the operations manager to identify the quiet weeks, the shifts when dock traffic is lightest and the sections of roof over the least sensitive freight. Each section is opened and dried in the same day, and a section over a critical zone is moved to a slower period. A plan that is shared early lets the operator tell customers what to expect.
For a roof with dry insulation and sound seams, a roof coating restoration avoids tear-off and shortens the disruption. Where the roof has failed, a commercial roof replacement can run in phases by bay. The photo record and moisture readings show which sections can wait and which cannot. Plants that ship their own product, as covered for manufacturers, face the same dock-edge questions, and a landlord such as an property management firm usually approves the schedule.
Price moves with roof area, layers, wet insulation, the count of penetrations and skylights, equipment lifts, and how many days the operator can accept access limits. A building with many dock doors has more edge metal per square foot of roof than an open box. Edinburg's adopted 2018 codes, building and energy, frame any replacement scope.
Distribution and warehousing activity sits among the local employers, and the labor market includes substantial transportation and material-moving employment. Operators near Pharr, where the I-2 and I-69C expressways meet, run the same roofs under the same weather. Owners of leased buildings can compare notes with distribution center roofing and warehouse roofing.
The lease answers that, and the operator's counsel reads it. What we provide is the factual record: photographs, moisture findings and a written cause. That record helps the operator and the landlord agree on the work, and it gives the operator what it needs to explain a delay to a customer.
The first step is a temporary dry-in over the opening, then plastic or tarps over the affected racking if the operator wants them. We photograph the opening before and after. Moving product is the operator's decision, and we tell the operations manager where the water will track so the right pallets move first.
In some buildings, yes, for the dock edge and for work that must avoid trucks. Night work needs lighting, a clear safety plan and approval from the landlord and the neighbors, and noise limits near adjacent properties can rule out tear-off after dark even when the dock is quiet. Where it is practical, we split the roof into sections and match them to the quietest dock shifts.
It does, because every support and conduit is a penetration and every new load can change drainage. We review the roof before installation, recommend which sections are sound enough, and coordinate the flashing so the new work does not void the repair history.
The latest condition report, the photographs of any repair, the moisture findings and the contact for emergency response. That file helps in a customer audit, an insurance review or a lease renewal. We update it at each visit so it stays current.
