Commercial EPDM seam leak detection works by combining close seam inspection with moisture mapping tools that can “see” where water traveled under the membrane. Pros look for edge lift, tiny voids in seam tape, fishmouths, and punctures near lap lines, then confirm the source using infrared scans, electronic leak detection, or smoke testing. The goal…
Ponding water on a flat roof is rain or snowmelt, often referred to as “standing water”, that sits in low spots instead of draining away. In Minnesota, it becomes a real problem when it stays longer than 48 hours, keeps coming back after normal storms, or pools near seams, drains, and penetrations. A simple ruler…
Flat roof leak detection is essential when there’s no drips inside, as a flat roof can leak without leaving a single ceiling stain because water intrusion often travels sideways above the deck. To locate it, start on the roof, not indoors. Inspect drains, seams, flashing, and penetrations, then narrow the search with moisture mapping (infrared…
Electric field vector mapping (EFVM), a form of electronic leak detection, finds flat roof leaks by sending a low-voltage pulse through the waterproofing membrane and measuring how that electrical field moves across a damp surface. Water in the roof assembly acts like a pathway, so the “direction” of the signal points back to the breach….
Infrared roof leak detection and thermal imaging, a non-invasive technology, finds moisture damage in flat roofs by spotting temperature difference that often signals trapped moisture under the roof membrane. Wet insulation holds heat longer than dry areas, so it shows up as warmer (or sometimes cooler) “blotches” on a thermal image. A trained technician maps…
Electronic leak detection finds holes in a roofing membrane by using a controlled electrical field. When there’s a membrane breach, electricity follows the path of least resistance, often through moisture, to the conductive deck or a grounded return line. The technician tracks that signal and marks the exact leak location, so repairs target the true…
Hail damage on EPDM roofs in Minnesota often looks subtle at first: small dimples, scuffs, or “bruised” spots in the rubber membrane. The bigger red flags usually show up at seams, flashings, and rooftop penetrations, where hail impact and temperature swings can open tiny pathways for water. If drains back up or metal edges get…
Commercial roof leaks are usually coming from one of a few repeat spots: seams, flashings at penetrations, drains, or edge terminations. Start inside by mapping the stain, then work upslope on the roof and inspect the most likely entry points for your membrane type (TPO welds, EPDM shrinkage, or modified bitumen laps and splits). Confirm…
Flat roof penetrations leak because they interrupt the roofing membrane and get stressed by movement, weather, and foot traffic. Most leaks start at weak flashing details around HVAC curbs, vent stacks, and pipes, or at seams that were rushed. Prevention comes down to proper curb height, watertight flashing, smart layout, and routine inspections after trades…
