What this record means for a Chatham roof

The list above covers 21 radar-confirmed hail days over Chatham between 2011 and 2026. The largest signature recorded over the Chatham area was 3.5" (baseball size or larger) on May 14, 2023. Radar put the local estimate at or above the 1" mark, the size generally capable of damaging asphalt shingles, on every one of those days.

Insurers and their adjusters can pull this same NOAA archive, so a date on this list is not news to the company handling a claim. What the archive cannot show is the condition of your specific roof, which is why dated photos and a written inspection report carry the weight in a dispute. Most homeowner policies also set a deadline to report storm damage, commonly one or two years from the date of loss, so a recent date above matters most if the roof was never inspected after it.

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.

Common questions

Has Chatham had hail big enough to damage roofs?

Radar has detected hail up to 3.5" (baseball size or larger) over the Chatham area, most recently on July 9, 2026. Hail of 1" or larger is generally considered capable of damaging asphalt shingles.

Does this prove my roof was damaged?

No. Radar estimates hail aloft, accurate to roughly a mile, and cannot confirm what reached any specific roof. It is a strong reason to document your roof and check your policy's claim deadline after a listed date, not proof of damage.
