Hail hit your area and the roof may look fine from below. These pages explain what hail damage looks like and how it connects to an insurance claim.
Look from the ground at the A/C unit, gutters, metal flashing, downspouts and patio furniture for impact dents.
Impact-resistant shingles are not hail-proof, but the Class 3 and Class 4 labels are real test results: steel balls dropped on a new shingle.
On a general weather scale, hail from 1 inch (a quarter) to 1 3/4 inches (a golf ball) is rated as causing minor damage. So size alone can't settle it.
Hail on asphalt shingles leaves a random pattern of impact marks, bruising and cracks, while blistering is listed among the signs of age.
