What techniques do insurance adjusters use to inspect a roof?
Test squares
The adjuster outlines a 10 by 10 foot area on each slope that faced the storm, counts qualifying hits inside it, and photographs the square with the count. Sampling every directional slope matters because hail usually falls at an angle and damages some slopes more than others.
Touch and look
Hail bruises often feel soft, like a bruised apple, because the mat underneath is fractured, even when granule loss looks minor. Adjusters run a hand over suspicious spots and look for exposed asphalt, cracks and punctures in a random pattern.
Wind checks
For wind, they look for creases across tabs where shingles folded back, broken seal strips, and missing shingles, usually starting at edges, corners and ridges where uplift is strongest. See wind damage roof claims.
Soft metal analysis
Dents in vents, gutters and downspouts show the size and direction of hail. Some inspectors rub chalk sideways across metal so shallow dents show up in photos.
Brittleness and repairability
On older roofs, an adjuster or roofer may gently lift a tab to see whether it cracks. Shingles that break when lifted cannot be repaired cleanly, which supports replacement over spot repairs; see partial replacement and matching.
Ruling out look-alikes
Blisters, foot traffic scuffs, nail pops and age-related granule loss get excluded, which is where many disputes start. Wear and tear vs hail damage explains how to tell them apart.
Technology
Drones photograph steep slopes safely, and aerial measurement reports supply roof size and pitch. Close-ups still matter: a drone image from high above can miss bruising that a hand finds immediately.
