Commercial Roofing
A ceiling stain after a hot afternoon in Edinburg, TX can point to moisture below the membrane, but temperature alone cannot confirm it. Infrared surveying helps locate surface patterns that may deserve closer inspection. We plan the scan for suitable conditions, review the roof layout, and compare the readings with visible seams, drains, curbs, penetrations, and interior reports. Roofs in the Valley hold heat for months, so temperature differences need careful interpretation. Hurricane Hanna brought wind and flooding impacts in Edinburg, which makes drainage and water paths part of a useful moisture review. We map anomalies, then verify selected locations with a hands-on check or approved test opening. The owner receives a record that distinguishes a thermal observation from confirmed wet material and shows where the next decision should focus.
Infrared equipment measures surface temperature differences. Wet insulation may retain heat differently from dry material, but shade, rooftop equipment, wind, surface color, and stored heat can also change the pattern. We plan the scan around those conditions and do not mark every temperature variation as moisture. A roof inspection checks the surrounding assembly and compares the scan with visible condition and reports from inside the building. If water has moved along a deck joint or insulation seam, the pattern can help direct follow-up toward a likely path.
Storms that bring wind and street flooding, as Hanna did in July 2020 and Dolly did earlier with gusts across Hidalgo County, put drainage and transitions on the list of places to scan. For a moisture survey after a wind-driven rain, we compare thermal patterns near openings and edges with the interior report, then test the locations that remain suspect. The scan is useful when it answers a focused question about an area the owner needs to inspect.
We review the roof plan, surface type, access route, equipment layout, and any known leak locations before collecting readings. Conditions must support a useful scan; if weather or stored heat obscures the comparison, we reschedule or change the inspection method. During the pass, we record the roof area and capture thermal and visual images that can be compared at the same location. We note conditions such as shade or rooftop units that may explain a temperature change. A drone survey can add broad visual context when access and flight conditions allow, but it does not replace thermal interpretation or close inspection.
After the scan, we select anomalies for verification rather than write a repair scope from colors alone. A probe, capacitance check, approved test cut, or other suitable field method can confirm the material response. Each location is photographed and tied to the roof plan. If the test is dry, we note the reading as an anomaly with a different explanation still possible. If insulation is wet, we map the confirmed boundary and identify the material that needs removal or further review. The report keeps both outcomes clear, and it lists the dry test points alongside the wet ones so a reviewer can see how far the scan was checked and where it was not.
Metal surfaces, reflective coatings, recent rain, shade, wind, and equipment operating below the membrane can affect the temperature pattern. Roof slope and thermal mass also matter. We consider the assembly before interpreting a cold or warm patch, then check the same place from a visual angle. If a surface anomaly lines up with a seam split, failed flashing, or drain, it becomes a useful inspection lead. If there is no matching roof defect, we may review interior conditions or choose another test. A flashing check can confirm whether a transition has opened beside the scan area.
The report identifies scan limits and the verification method used. If a roof has multiple layers, the surface reading may not show the depth or exact extent of trapped water. We avoid promising a boundary before the test locations support it. When confirmed moisture leads to a larger removal or replacement scope, we review the permit path and assembly details before work proceeds. Technical interpretation stays tied to the material and conditions at the tested location.
Confirmed wet insulation is mapped against dry areas so the owner can see where removal may stop. We examine the deck and adjacent materials when an opening is approved, then replace unsound layers within the scope. If moisture is localized around a failed drain or flashing, the repair can address the entry detail and the affected material. If readings and tests show spread across multiple sections, replacement or restoration may need review. The recover assessment should not cover a wet layer without stating the condition and a suitable correction. The scope records whether the insulation, cover board, or substrate was affected and what material must be removed. Where the test opening reveals a different condition, we revise the plan before closing the roof.
We discuss the findings with the facility director before changing the work boundary. Cost and timing depend on access, the number of test areas, material removal, deck repairs, weather protection, and equipment nearby. A condition report can group verified locations by priority and show the photos that support the recommendation. The owner can compare an immediate repair with a phased correction without treating every thermal anomaly as a leak.
A useful record pairs thermal patterns with visual images, roof-area labels, scan conditions, and the outcome of follow-up checks. We identify which points were confirmed wet, which were dry, and which remain uncertain. That prevents a future reviewer from treating a color pattern as a defect without context. We also note drains, seams, edges, and penetrations adjacent to verified moisture, since those details can explain how water entered. The record can guide repair work and later maintenance checks.
For a property within the Edinburg service area, the scan can establish a repeatable baseline for known suspect zones. A maintenance visit can revisit the same areas after repairs or storms. The roof surface itself remains the final evidence: thermal readings help direct attention, and field tests decide whether moisture exists. We close with the confirmed boundary and the recommended action, so the facility director has a clear next step.
No. It shows surface temperature patterns that may point to a moisture concern. We verify selected areas with suitable field methods and compare them with the roof assembly and interior evidence.
The roof and weather conditions need to support temperature comparison. Wind, recent rain, shade, and stored heat can affect readings, so we review conditions and adjust the timing or method when needed.
No. We select follow-up locations based on the scan and inspection findings. An approved test opening is used only when it will help confirm material condition and define the repair boundary.
Different membranes, metal surfaces, insulation layers, and equipment can alter readings. We consider the roof construction and verify anomalies rather than apply a single interpretation to every assembly.
The report separates confirmed wet material from unverified patterns and ties both to roof locations. That gives the facility director a basis for localized repair, additional testing, or a larger scope review.
