Commercial Roofing
A Sika Sarnafil roof should be evaluated as an installed assembly, not just a PVC sheet with a familiar label. In Edinburg, TX, we inspect membrane seams, flashings, penetrations, edge securement, drains, and any areas changed by later work. Hanna's July 2020 visit meant wind, street flooding and at least one roof stripped of shingles in the city. That makes drainage and exposed transitions useful after-storm checks, while the actual roof determines whether damage is present. A commercial roof inspection connects the visible defect to its water path and records whether the surrounding membrane can support repair.
We check the exposed membrane, seam type, flashing details, edge terminations, and the layers beneath the sheet. A Sika Sarnafil system may have undergone a repair, coating, or addition since installation, so we identify current conditions rather than assume every section matches. A test weld on a clean area can help determine whether the membrane can receive a compatible repair. If the surface is contaminated or degraded, preparation changes. The PVC assembly needs a sound, compatible tie-in at both the field and the detail.
Penetrations and wall transitions deserve the same attention as field seams. A curb may have been modified for replacement equipment, or another trade may have routed a support across the membrane. We inspect the flashing height, termination, movement, and nearby surface, then note what must be reopened to restore continuity. The roof plan and photos keep the location clear for the owner and for future service. If the system's identity or lower layers remain uncertain, an approved opening can confirm them before the crew selects materials. That step prevents a repair from being based on an assumed substrate.
In populated Hidalgo County, Dolly's gusts reached 50 to 70 mph and caused minor damage; Edinburg, Pharr, and McAllen were included. After a tropical event, we inspect corners, perimeter metal, terminations, rooftop equipment, and flashing where wind pressure or water could expose a weak detail. We do not infer a property-level failure from the county event. We look for movement, open seams, displaced covers, and water tracks at the building itself. A wind-damage review documents those findings and identifies any test needed before permanent work.
Rain can also show a drainage issue that predates the storm. We check strainers, scuppers, overflow routes, and low areas, then see whether water remains against a curb or seam. A PVC membrane may remain intact while a wall termination or drain connection has failed. The scope should name that exact detail and show where the repair stops. If water has reached insulation, we mark the boundary and determine whether material must be removed. The photo record separates surface wear, confirmed moisture, and conditions that still need a test opening.
We begin with the interior symptom, then inspect the roof above and upslope. Water can travel along a deck joint or insulation plane before appearing at a ceiling, so we compare slope, seams, curbs, and nearby penetrations. A moisture survey can help locate temperature differences for follow-up. Readings, probes, or an approved test cut establish what is happening inside the roof layers. We place those points on the roof plan and photograph the conditions before material is removed.
Permitted work in Edinburg is governed by adopted 2018 editions of the city's building and energy codes, which we check when the scope changes the assembly. When a repair expands into replacement or an assembly change, we review whether permitting and current project requirements affect the scope. We do not treat a code reference as proof that a particular roof needs upgrading. The inspection records the existing construction and the proposed work so the facility director can review the decision. If the membrane is sound but insulation is wet, a limited opening and replacement may be possible. If moisture is widespread, a broader restoration or tear-off should be compared.
A local repair is reasonable when the membrane around the defect remains compatible, clean, and dry and the substrate is stable. We prepare a test area, verify the weld, and rebuild the flashing or seam to match the system. A commercial roof repair may correct a limited puncture or open transition without replacing sound sections. If seam failures repeat, attachment is weak, or moisture crosses multiple areas, we expand the investigation before proposing another patch.
A recover adds material and can change height, drainage, and terminations. We compare those effects with removal, deck condition, roof access, equipment, and the need to keep interior areas protected. Where the existing assembly cannot support another layer, a replacement scope should identify removal limits, tie-ins, and how water will leave the completed roof. Cost depends on the materials, access, staging, penetrations, and any wet or unstable layers discovered during opening. The owner receives the conditions behind the estimate, not a product recommendation detached from the roof. We note which layers remain, what the repair will cover, and any test or opening that could change the final quantity. A clear boundary also helps protect adjacent roof areas during tear-off and makes closeout photographs easier to compare with the original condition.
We divide work by roof zone, access, and the activity below it. Facility staff can identify rooms, equipment, deliveries, or operations that need protection while the crew opens a section. We agree on material staging and temporary dry-in before work begins, then close each active area as the assembly allows. A Downtown Edinburg roof visit still needs property-specific access planning; a street name or district does not establish where a crew can stage.
At closeout, we photograph the seams, flashings, drains, and any area that should be checked again. A maintenance visit can find new penetrations, debris, or edge movement before water reaches occupied space. When portfolios include different manufacturers, a GAF assembly and a Carlisle SynTec roof keep separate material records and repair details. We organize those observations with condition reporting so the facility director can set follow-up around actual conditions. Emergency response is available at any hour, on weekends and holidays as well as regular workdays. We photograph each repaired seam for closeout.
We verify the installed membrane and test compatibility before choosing repair material. The seam and flashing must bond to the existing surface after proper preparation; a generic label does not confirm that result.
We compare the interior mark with roof slope, deck joints, curbs, drains, and penetrations. Water can travel before it reaches a ceiling, so we trace the path and test the suspected layers before setting the repair boundary.
No. Hanna affected Edinburg with wind and flooding, but the roof's current condition decides the work. We inspect seams, edge details, drainage, and insulation, then document whether the issue is local or broad.
Only if the substrate and membrane qualify for that system. We check adhesion, moisture, seam condition, and drainage first; coating does not restore an open joint or wet insulation.
We coordinate access, staging, and work zones with facility staff and keep open areas protected. The inspection identifies which roof sections can be isolated and what must remain available below.
