Commercial Roof Repair Leaks, Membrane & Flashing Failures

Water travels along a flat deck before it drops, so the stain inside is rarely under the entry point. We trace the path back to the actual failure rather than patching the visible symptom.

Split seams, punctures, blistering and shrinkage on modified bitumen and single-ply systems. Repaired with compatible materials so the patch bonds properly instead of lifting at the next temperature swing.

Most commercial leaks start at a penetration — HVAC curbs, vents, drains, skylights and parapet walls. These are the details we check first because they fail long before the field of the roof does.

Standing water is the leading cause of flat roof failure in the Valley. We correct drainage and add tapered insulation where needed rather than repeatedly repairing the same saturated area.

Where water has been getting in for a while the decking underneath is usually compromised. We remove the wet material, address the source, and rebuild to a sound substrate before the new surface goes down.

Active leak during business hours? We can tarp and make temporary repairs the same day to stop interior damage, then schedule the permanent fix around your operations.

For an active leak we prioritise same-day temporary containment across the Rio Grande Valley. Permanent repair is scheduled after, around your operating hours. Call (956) 345-7700 and we will tell you honestly when we can be there.

It depends on how much of the roof is affected and the condition of the decking and insulation underneath. If failures are isolated, repair is almost always the better value. If the substrate is saturated across large areas, repairs become a recurring cost. Our free assessment tells you which situation you are in, in writing.

It tells you where the wet insulation is, which is the single most useful fact about a commercial roof. A membrane can look intact from above while the board beneath it has been saturated for years, and wet insulation loses most of its thermal value, adds substantial dead load and corrodes a steel deck from underneath. Surveying maps the wet areas so a repair can cut out and replace only what has failed, rather than sealing the top and leaving the problem to spread.

They can, and it is the most common way building owners lose cover without realising. Most manufacturer warranties require that repairs be carried out by an approved contractor using specified materials and methods. A cheap patch in the wrong sealant can end a warranty with fifteen years left to run. We check what warranty is in force before touching the roof, work to its terms, and document the repair so the cover survives the visit.

Almost never the price of the repair. The real cost sits in the stock, equipment or fit-out underneath, in the hours your staff spend moving things and mopping, and in the tenant relationship if you are the landlord. Wet insulation also raises the cooling load on a Valley building every month it stays wet. That is why we quote a repair against what the delay costs rather than in isolation, and why the assessment is free.
