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.
Find licensed roofers near you on AngiReferral disclosure: this site may earn a fee if you request quotes through this link. That does not change what you pay, and no contractor pays to be described a certain way here.
Before you sign anything, read the contractor red flags: assignment-of-benefits traps, deductible games, and storm-chaser tells.
