Has severe hail hit Weld County since my roof was put on?
Our record covers 2014–2026 only. A roof older than 2014 has also been through hail we do not show here. A day counts when at least one report of 1 inch or larger was filed in the county, so it does not mean your own roof was hit; an inspection is the only way to know.
