Commercial Roofing
A Versico membrane can be TPO, PVC, or EPDM, and the seam method changes with the material. In Edinburg, TX, we identify the roof before selecting a patch or restoration scope, then inspect edges, penetrations, drains, and the insulation below. Sustained solar load is part of the Valley roof picture from May through October, especially at membranes and exposed sealants. Our inspection records the actual condition and the repair boundary rather than relying on a name in an old file. A commercial roof inspection gives the facility director a clear view of what can stay and which test is needed next.
Versico's product families include VersiWeld TPO, VersiFlex PVC, and VersiGard EPDM. We verify the installed membrane by checking exposed edges, seams, surface markings, flashings, and available project records. A thermoplastic sheet is repaired with compatible welding and detail materials; EPDM requires its own surface preparation, tapes, or flashing. An older roof may combine a current membrane with a recover or repairs from another period. The TPO system and EPDM system need different methods even when they cover similar low-slope buildings.
We also inspect the cover board, insulation, attachment, and deck where the condition can be confirmed. A soft spot, damp reading, or loose area near a curb can change the repair boundary. If records and field clues do not identify the layers, we describe what remains uncertain and consider a controlled opening. That avoids naming a product from color alone or assuming an old invoice matches a later addition. We photograph each test point before removal. The report identifies the roof sections, materials, and details observed so a property manager can compare the scope with later service without mixing unlike assemblies. We distinguish surface marks from a split or puncture that breaks membrane continuity. At a suspected wet area, we note whether the test reached the insulation or only the top sheet. The difference affects removal, drying, and how the repaired section can be closed before weather returns.
Large hail is not routine in the Valley, but a spring 2012 storm carried large hail across the McAllen-Edinburg-Mission-Pharr metro. After a severe hail event, we inspect the membrane, edge metal, rooftop equipment, penetrations, and flashings for visible impact or new openings. We distinguish damage from surface marks that do not change the assembly. The event is a reason to look, not evidence that a particular roof was struck. A visual inspection records the observed areas and any closer testing needed.
Wind calls for attention to corners, terminations, and perimeter securement. Gusts from 50 to 70 mph during Dolly caused minor impacts in populated Hidalgo County communities that included Edinburg, Pharr, and McAllen. We check for lifted edges, open seams, loosened flashing, or movement around equipment. Water may enter at a transition even when the field membrane looks intact, so the inspection follows the detail into the adjacent surface. A wind-damage assessment separates a local attachment issue from broad failure. The next repair should restore a defined connection rather than cover a larger area without a reason.
A ceiling stain may sit several feet from the roof opening. We compare the mark with deck joints, slope, insulation, seams, curbs, and roof-to-wall transitions, then inspect upslope. Moisture readings can show a pattern, while a probe or approved test cut confirms the material condition. A moisture survey can guide those checks, but the repair boundary follows field confirmation. We mark test points on the roof plan and photograph the material before removal.
Edinburg's building and energy conservation codes are the 2018 editions. If the repair becomes a larger roof replacement or changes the assembly, we review permitting and project requirements before setting the work sequence. The code reference does not establish a defect or prescribe a system for an individual building. We document the existing layers, drainage, access, and any open questions so the owner can review the proposed scope. If insulation is dry around a seam, a focused repair may be supported. If wet material extends across bays, we pause and map the area before covering the roof again.
A Versico seam can be repaired when its surrounding membrane is compatible, clean, and strong enough for a tested weld or bond. We prepare a dry test area, confirm the seam, then rebuild the flashing or edge detail. A commercial roof repair can remain local when the substrate is stable and moisture is contained. If seams keep opening or insulation is wet across several sections, we expand the assessment rather than add repeated patches.
A recover can retain a roof only when the existing assembly, deck, attachment, height, and drainage support another layer. Equipment curbs, overflow routes, roof edges, and transitions can be affected by added thickness. If moisture or unstable material needs removal, a replacement scope may be the better comparison. We describe material removal, tie-ins, staging, and protection for occupied spaces before assigning schedule and cost. The owner sees which finding led to each option and what test would change the conclusion. That makes the difference between a repair and a larger project clear on the record.
Closeout photographs show the seam or flashing before and after repair, the adjacent membrane, and any insulation removed. We note remaining issues and the location of each test point so future inspections can return to the same area. A maintenance visit can check drains, new penetrations, and exposed terminations as other trades work on the roof. For roofs across McAllen and Pharr, we keep each system record separate rather than assuming identical conditions.
When a portfolio has several manufacturer assemblies, the field method remains specific. A Carlisle SynTec membrane and a Johns Manville system each require their own compatibility check, just as a Versico sheet does. The team coordinates access, staging, and protection with facility staff before exposing an occupied area. Emergency response is available around the clock, seven days a week, including holidays, when an active leak needs attention. The final record states what was restored, what remains outside the scope, and when a follow-up check is useful.
We combine project records with field clues at seams, edges, and exposed material. If a previous overlay or repair obscures the roof, we identify the layers that can be confirmed and test where product identity changes the repair method.
No. The membrane and seam method must match. We verify whether the roof is TPO, PVC, EPDM, or a mixed assembly, then prepare and test the repair on the material in place.
The event alone does not decide the scope. The 2012 hail event affected the McAllen-Edinburg metro, and we inspect the actual membrane, metal, flashing, and equipment before recommending repair or replacement.
Readings help map likely wet areas, but a probe or approved opening confirms the layer. We mark the boundary and explain whether removal, drying, or additional testing is required.
We divide the work area, coordinate access and protection, and plan how each open section will be closed. Facility operations and weather conditions shape the sequence.
