what size hail will damage a roof

According to the search results, hailstones larger than 0.5 inches can damage a roof. However, hail around 1 inch in diameter or bigger will cause dents and compromise the integrity of asphalt shingles, which will warrant an insurance claim. Hailstones of 1.5 inches or larger can cause more significant damage. Wind speed can also affect the extent of roof damage. Therefore, it is important to assess the size of hailstones and the accompanying wind speeds to determine the potential damage to the roof.
