Commercial Roofing
An owner with an aging flat roof usually asks one question before any other: can this be recovered, or does it have to come off? The answer sits in the layers under the membrane, and the way to read them is to open the roof in a small area, look and measure. On the FM 1015 corridor in Edcouch, TX the same question applies to a service building, a small retail space or a storage structure, and the first step is the same: choose a dry test area, cut a sample and read what is there.
That sample changes the scope more often than any ceiling stain does. A dry core means a recover option is open. A wet one means the repair boundary is wider than it looked, and the conversation moves to phased restoration or replacement. Neither answer is a verdict on the whole building until the moisture scan confirms the sample speaks for the surrounding roof.
We pick a spot that is representative and away from known leaks, cut a small square through membrane and insulation, and record each layer: membrane type and thickness, insulation type and thickness, adhesive or fastener attachment and deck. We read moisture in the insulation with a meter and photograph the section against a scale. Attachment matters as much as moisture: we note whether the membrane is adhered, mechanically fastened or ballasted, because a recover over an adhered system is built differently from one over a fastened system, and the fasteners we find set the pull-out pattern for the new layer.
A dry, well-bonded assembly can carry a roof recover, subject to weight, wall heights and the number of existing layers. A wet or crushed assembly cannot. Test areas are patched the same day with matching membrane, a proper lap and sealed edges, and logged on the plan, and a wide moisture scan shows whether the sample speaks for the roof or only for its corner. An infrared moisture survey ties the cut to the whole surface. Where the survey shows a patchwork of wet and dry areas, we cut a second and third sample at the boundaries and mark them on the plan, so the final map of the roof rests on several samples and not one.
Weather Service guidance covers hurricane readiness from June through October and flood preparedness year-round across the Rio Grande Valley, so wind and rain checks are routine for commercial roofs in Edcouch. Wind finds weak edges, loose flashings and rooftop equipment. Rain finds anything the wind opened and any low point where water collects.
On a small building the whole roof is a few details. Perimeter metal, wall transitions, one or two penetrations and a single drain or scupper decide whether it stays dry. We check each, photograph each and test the drain by running water to see how fast the outlet clears, then look at the roof surface around it for staining that shows where water lingered. A building with a history of wind damage gets the edge and equipment checked first, then the field. Heat belongs in the same check, since the Weather Service names May through October as the Valley's heat-safety season, and a seam that has been cooked for months fails more easily when a storm arrives.
Edcouch identifies itself at the junction of SH 107 and FM 1015 in Hidalgo County, and the metropolitan plan identifies FM 1015 widening between FM 1925 and SH 107. For roofers, a junction means turning movements and traffic, and a widening means construction that may close shoulders and change driveways. Project lists say what is planned, not what is open today, so we confirm site conditions before setting dates.
Many small commercial lots have one drive approach and little yard. Material goes up in daily quantities, the lift stays off the driveway when customers need it, and each evening the facility director hears what is closed in and what is not. A building next to a widened road may also see its entrance change during construction, so we ask where customers park and where deliveries arrive, and we guard those routes during hoisting with barriers and a person watching the drop zone.
The boundary follows moisture, not the stain. A leak in one corner can be a local seam failure over dry insulation, or it can be the visible edge of a wet zone that extends across a bay. Photographs and moisture readings together decide: dry beyond the defect means the repair stays tight, and wet beyond it means the boundary moves out until the readings are dry.
When the boundary grows large enough that the repair is a major portion of the roof, we price replacement of that section alongside it, with the tear-off line drawn at the wet edge and the dry roof beyond it left in place. On a building where the owner plans to sell or refinance, that comparison also shows what the roof will look like to a buyer's inspector. A section replaced with a new membrane, flashing and drain details looks different on a report than a roof with a dozen patches, and the photo record shows both conditions plainly.
A written set of options with the evidence beside each: photographs of the test area and the moisture map, the repair list, the recover or replacement scope and the order of work. For an owner with a restaurant or retail space, the plan also lists how the restaurant roof work protects the kitchen and dining area during each phase.
Owners with properties in Edcouch, Elsa or La Villa can keep one record format for all of them, which makes it simple to see which roof has the widest repair boundary and which can wait another season.
Almost nothing in the roof itself, since the cut is small and patched the same day. The value is in the information: type, thickness and moisture of each layer. It often changes a quote, since a dry core can open a recover that a wet core would close.
That depends on the existing assembly, the weight limit of the structure and the code. A roof that already carries multiple layers may need a tear-off. The test area shows how many are there.
If the repairs recur, yes. A pattern of leaks at the same seam or drain means the scope has outgrown patching. The record of past repairs shows the pattern, and a map of leak locations over several years shows whether the failures cluster at one drain or one wall.
We close in every open area, secure materials and tarps, and pause. The log records what was covered and when, and the first walk after the storm checks edges and drains before work restarts.
It can. Local review varies by city, and Edinburg, for example, lists the 2018 International Building and Energy Conservation Codes among its adopted codes. We confirm the applicable review for each address before scheduling, and we put the permit date in the schedule so the dry-in date and the inspection date line up.
