What your policy says matters next
After hail, your own policy decides what you pay first and how a roof gets paid. DecodeMyPolicy reads your homeowners policy and explains, in plain English with page citations, your wind and hail deductible in dollars, how the roof is paid, exclusions and deadlines. $19 plus tax. It was built and tested on Texas policies first and reads any homeowners policy.
What this page shows, and what it does not
A radar hail signature means the storm over that spot likely held hail of the estimated size; it does not prove hail reached the ground at any one house. Spotter reports confirm hail on the ground at the reported spot. Nothing here assesses damage to any property or says whether to file an insurance claim; only an inspection can tell you about your roof.
