You detect a built-up roof leak without core cuts by layering built-up roof leak detection methods, not by guessing. Start with interior leak mapping, inspect the roof surface, scan for trapped moisture with infrared, confirm wet areas with a moisture meter, and use electronic leak detection when the roof surface allows it. That usually narrows…
Short answer: To detect a TPO roof leak at termination bars, start by tracing interior stains to the nearest roof edge or parapet. Then inspect the termination line for cracked sealant, loose fasteners, membrane shrinkage, and wall gaps. Confirm hidden moisture with infrared or electronic testing, because water often travels inside the roof assembly before…
Look for fresh, sharp-edged impact marks along the roof’s highest line. On asphalt shingle ridge caps, that often means round granule-loss spots from impact damage, “bruises” that feel soft when pressed, or cracked corners. On metal ridge caps, watch for dents, scuffed coating, and loosened fasteners. Compare both sides of the ridge, because hail usually…
Yes, ballasted EPDM leak detection can work with electronic leak detection (ELD), but not in a “scan right over the rocks” way. In most real-world cases, crews must move ballast in controlled sections to expose the EPDM membrane, wet this synthetic rubber surface, and then test. If the roof was built with ELD-friendly components, results…
A hidden roof leak in walls usually shows up as subtle changes before you ever see water damage. Watch for water stains near the ceiling line, bubbling or peeling paint, soft drywall, a musty smell, or damp insulation behind the wall. In commercial buildings, leaks often travel far from the roof entry point, so the…
Short answer: Detect an HVAC curb flashing leak by inspecting the curb’s corners, seams, and termination points, then confirming moisture paths with interior checks. Look for cracked roofing sealant, open welds, lifted membrane, rusted fasteners, and ponding that pushes water against the curb. If signs are mixed, use targeted moisture mapping or a controlled water…
A TPO roof leak at HVAC curb corners is found by narrowing the leak path from the interior, then inspecting every curb corner detail on the TPO membrane: welds, flashing, termination, fasteners, and sealant transitions. Finally, confirm the exact breach with controlled water testing or professional methods like infrared or electronic leak detection, because water…
For Twin Cities commercial roofs, TPO vs. EPDM comes down to what you need the roof to do most. EPDM roofing often wins for cold-weather flexibility, proven longevity, durability, and budget-friendly installs. TPO often wins for heat-welded seams, puncture resistance, and lower summer cooling load. The “better” choice is the one that matches your roof…
Most flat roof leak detection appointments on commercial and industrial roofs take 2 to 6 hours onsite. Simple, visible water intrusion leaks can be traced in 1 to 2 hours, while larger roofs or tricky leaks often need a half day. If the team uses thermal imaging cameras, electronic testing, or moisture mapping, plan on…
Hail damage vs weathering process usually comes down to pattern and texture. Hail damage leaves random, coin-sized bruises and sharp granule loss in scattered spots. The weathering process looks even, with gradual fading and uniform granule loss along edges and high-flow areas. If you see circular impact marks, matching hits on vents, and fresh granules…
A skylight flashing leak usually shows up as a roof leak in the form of staining that starts at the skylight’s edges (often the uphill side) and worsens during wind-driven rain or thaw cycles. A skylight unit leak or condensation issue tends to leave moisture on the glass, frame, or inside corners first. The fastest…
A capacitance meter finds wet insulation by sensing changes in an electrical field across the roof assembly. Because water stores electrical charge differently than dry insulation, wet areas create higher capacitance readings. During capacitance roof testing, a technician scans the roof in a grid, compares readings to a dry baseline, then maps “hot spots.” Final…
