Start inside. Photograph any ceiling stains, water trails on walls, or attic moisture. Note the location relative to exterior features (chimney, vent, valley).
Check for daylight, moisture on rafters, staining on the decking. Trace any visible wet trails back toward their origin. This is safer than roof walking.
From the ground, scan all slopes for missing shingles, visible lift, dark patches, and discolored areas. Use binoculars if needed.
Heavy granule deposits confirm shingle wear. Debris dams confirm that gutter cleaning is causing backwater pressure at the eaves.
Match the location of interior symptoms to the exterior roof zone directly above. Note all penetrations (vents, chimneys, skylights) in that zone.
Send photos and describe the symptoms. A professional will schedule an inspection and provide a written finding and repair scope.
