Use the ground first, not the roof. A safe roof hail damage inspection relies on binoculars, drone photos, metal impact clues, interior moisture signs, and, when needed, infrared or electronic testing. This works best when shingles are steep, brittle, wet, old, or part of a larger commercial property where foot traffic could create more damage….
Short answer: You’ll suspect roof decking rot when your roof system shows ongoing moisture infiltration plus structural “softness.” Inside, watch for recurring ceiling stains, musty smells, or bubbling finishes. On the roof, look for ponding water, failing seams, or spongy areas that flex under safe, limited foot pressure. In Minnesota, freeze thaw cycles and Minnesota…
Usually, a yellow ceiling stain means moisture got in at some point, but it isn’t always an active roof leak. If the stain is growing, feels damp, or shows up after rain or snowmelt, treat it as a current leak until proven otherwise. If it’s dry, crisp-edged, and hasn’t changed in months, it may be…
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…
Start by inspecting the rubber pipe boots where they hug the pipe, then the base flashing where it meets the roof. Look for radial cracks, splits at the top edge, loose sealant, and lifting edges from freeze-thaw. On Minnesota commercial roofs, check after big temperature swings and after snow events, then document damage and schedule…
If you’re wondering what common signs of roof damage are, start by scanning for missing or curled shingles, granule loss, and water stains in the attic. These visible issues often appear before leaks or wider deterioration and can be easy to miss. In Minnesota, freeze-thaw cycles and frequent storms speed up wear, so a small…
A dormer roof leak is usually found by tracing water backward from the first interior stain to the highest wet point, then checking the dormer’s flashing, valleys, and shingle courses above that spot. Start inside (attic or ceiling), mark the drip line, then inspect uphill around step flashing and the dormer cheeks. If needed, run…
To detect a commercial roof scupper leak, trace water from the inside out, then confirm the source at the roof edge. Start by mapping interior stains, inspect the scupper opening and roof flashing, and check the roof membrane upslope where water feeds the scupper. Finish with a controlled water test or professional moisture testing to…
Identifying hail damage is critical for maintaining a standing seam metal roof. Standing seam hail damage usually shows up as fresh dents in the flat pans, bruised ridges near the seams, chipped coating that exposes bare metal, and bent edge metal or flashing. The quickest way to confirm it is to compare impact marks across…
A hail test square is a measured 10×10 ft square (100 square feet) section of roof used as a sample area to assess hail damage after a hailstorm. Inspectors mark the square, examine it closely, then count only the hail impacts that cause functional damage (dents, fractures, punctures, or bruising that shortens roof life). Those…
A professional roof inspection and roof leak detection report for insurance should be performed by a licensed, insured commercial roofing professional (or an independent roof consultant) who can document cause, location, and extent of damage with photos, test results, and clear repair scope. Avoid relying on maintenance staff or a general handyman. Insurers want credible…
Short answer: Look for fresh granule loss, sharp chips, and small cracks right at the shingle’s outer edges and corners. Hail hits often leave random, uneven marks, not a uniform “worn” look. Check for bruising (a soft spot) under the granules, and compare several areas on different slopes. If multiple corners show fractures, the roof…
