Get the roof inspected, free

Radar cannot confirm what hit your shingles; an inspection can, and it costs you nothing. Angi matches you with licensed local roofers who inspect for free and bid the work. Know how it works going in: the roofers pay Angi for the introduction, you pay nothing, and more than one company may call. That is the useful part: multiple written estimates are exactly what you want in hand before an adjuster visit or a contract.

How to read this page. These are radar hail signatures: estimates of hail aloft, accurate to roughly a mile. They are strong evidence a storm produced hail in an area, not proof of damage at any one roof. If a date here matches when your roof was last replaced or inspected, the address lookup will show what the radar saw over your specific property.
