Commercial Roofing
A manufacturer's name tells an owner what the roof is made of; the installation tells an owner how long it will last. In Edinburg, TX I look at both. The membrane on the roof, whether TPO, PVC, EPDM or bitumen, sets how seams are joined, how flashings are detailed and what a repair needs to bond to. Knowing the system before the first tool comes out keeps a repair from fighting the roof.
We install, repair and maintain commercial systems from the manufacturers listed here, among them Versico, Carlisle SynTec, Duro-Last, Sika Sarnafil, Soprema, GAF, Johns Manville and Holcim Elevate. The manufacturers own their names and products; the work is ours, and the pages describe the system types in general terms.
Before any repair, we identify the membrane, the attachment method and the layers beneath it. A core sample or a lifted seam usually answers that. A hot-applied bitumen roof, a heat-welded single-ply and a liquid-applied coating each take a different repair. Matching the repair to the system is what keeps it from failing at the edge of the patch, and it is why the first visit includes a close look at seams, laps and every flashing termination.
Heat sets the load: the National Weather Service marks May through October as the Valley's heat-safety season. Wind and rain matter too: gusts from Dolly crossed the county, and Hanna's wind and flooding followed in July 2020. A system is judged by how its seams, edges and drains hold under those loads.
Single-ply membranes depend on clean, dry substrates and carefully formed seams. Bitumen systems depend on temperature, adhesion between plies and flashing detail at the walls. Metal systems depend on clips, fasteners and panel ends. Coatings depend on surface preparation above all. We follow the manufacturer's published instructions for the system in front of us, and we record each step with photos so the finished roof can be compared with the intent.
Maintenance follows the same logic. Drains are cleared, seams are probed, sealants are checked and small defects are repaired before the heat season builds on them. Records stay with the building, so the next visit starts where the last one stopped.
The system type does. Materials from different makers can share a type, and the repair follows the type.
Yes, when sections have been replaced at different times. Each area is repaired for what it is.
If a warranty exists, we read the conditions before any work and keep records so the paperwork stays consistent.
A core sample and a seam check identify it, and that identification goes into the report.
