Short answer: On algae-streaked asphalt shingles, hail damage usually shows up as crisp, round spots of granule loss, small cracks, or “bruises” that feel soft when you press them. Algae staining looks like a surface smear or streak, not distinct impact marks. Confirm hail by checking matching dents on metal roof parts, then photograph patterns…
A TPO wall flashing leak, a common roof leak on a flat roof, is usually found by tracing water from the interior stain back to the nearest wall, then inspecting the roof to wall flashing where the TPO membrane turns up the wall. Focus on terminations (termination bars, counterflashing, reglets), corner patches, fasteners, and sealant…
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…
Yes. Hail damage, a common form of storm damage, can weaken a roof without cracking asphalt shingles or leaving obvious holes. Impacts can bruise the shingle mat, knock off protective granules, loosen fasteners, and stress seams and flashing. On low-slope commercial roofs, hail can cause small punctures or membrane fractures that stay hidden until leaks,…
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…
Cedar shake hail damage usually shows up as fresh splits, broken corners, crushed wood fibers (bruising), and shaken-loose pieces that expose roofing underlayment or fasteners. Start by confirming a recent hail event using “collateral” clues like dented gutters and marked flashing, then inspect the wood shake shingles for random, storm-pattern impacts. Photograph everything and get…
Water stains on ceilings help you narrow the search, but they rarely mark the exact roof leak. Start by confirming the stain is active, then check what sits directly above it (roof deck, drains, HVAC curbs, or plumbing). Next, trace the most likely uphill water path on the roof to find the leaky roof, focusing…
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…
To document roof hail damage for insurance claims, take wide photos of the entire roof, slope-by-slope roof images, close-ups of shingle impact marks, and photos of dents on soft metals like gutters and vents. Include a ruler or coin for scale, and document the storm date and any temporary repairs. Proper photo documentation helps prove…
Most TPO roofs last 15 to 30 years, with 20–25 years typical for properly installed systems that receive regular maintenance. Property owners should begin budgeting for replacement around year 15 and schedule professional inspections between years 10 and 15 to evaluate roof condition, review warranty coverage, and identify hidden damage. Regular maintenance and prompt repairs…
PVC roof leak detection works by narrowing the problem from “moisture intrusion inside” to the exact point where the PVC waterproofing membrane or flashing lets water in. Pros use Electronic Leak Detection, combining surface inspection, seam and flashing checks, moisture scanning (often infrared), and electronic membrane testing to trace the leak’s path, pinpoint membrane breaches,…
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…
