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…
Short answer: Identify hail damage on luxury asphalt shingles by looking for random impact marks across multiple slopes, fresh granule loss with dark asphalt showing, cracked or bruised spots that feel soft when gently pressed, and matching damage on roof “soft metals” like vents and flashing. Document findings with clear photos, note the storm date,…
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…
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…
If a storm has left your roof exposed, you likely want to know how long a tarped roof will last. Emergency tarps typically protect a roof for about 30 days to six months, depending on material, installation, and exposure. Thin blue polyethylene tends to sit on the short end of that range, while reinforced, UV-treated…
Commercial TPO leak detection works by combining surface inspection with moisture-mapping tools that “see” what your eyes can’t. Pros look for seam and flashing failures, then use infrared thermography to locate wet insulation patterns and electronic leak detection to pinpoint the exact hole in the membrane. The goal is simple: find the true entry point,…
Short answer: To spot hail damage roof valleys, focus on what valleys do best: collect water, granules, and debris. From the ground, look for streaks of washed-out granules, bent or dented valley metal, and uneven shingle lines where the valley “channels” runoff. If you can access the roof safely, check for circular bruises, granule loss,…
Earliest roof leak signs in a finished attic usually show up as small changes, not dripping water. Watch for faint yellow or brown staining at ceiling corners, bubbling paint, a musty odor that comes and goes, or trim that starts to warp. In commercial spaces, you may also notice damp insulation behind knee walls, rust…
TPO hail splatter marks are subtle dark speckles left on thermoplastic polyolefin roofs after a hailstorm. Unlike dirt or foot‑traffic scuffs, these peppery gray or black dots don’t wash away easily. Knowing how to recognize TPO hail splatter marks helps property owners decide if their roof has been compromised and whether to bring in a…
Short answer: The first hidden roof leak signs in drywall are usually faint yellow or brown water stains on ceilings, paint that starts to bubble, and drywall that feels soft or swells near seams or fasteners. You may also notice musty odors before you see obvious dripping. In commercial spaces, these clues often appear after…
A flat roof parapet leak usually comes from one of three places: the roof membrane’s transition to the parapet wall, the metal coping on top, or a drainage opening that cuts through the parapet (like a scupper). To find it, start by tracing interior staining to the closest wall line, then inspect parapet flashings, terminations,…
A wind-driven roof leak usually enters on the windward side during wind-driven rain, then travels before it shows up inside. Identifying the source of a roof leak is the first step in proper roof maintenance for Minnesota property owners. To find it without climbing, document the wind direction, then take eight clear ground photos of…
