Hail damage often presents itself as small dips or breaks in a roof. The size of all these things can vary and fall completely at random. Even if you do not see indentations on the shingles themselves, you may still find proof elsewhere. If you find depressions in gutters, siding, skylights, or chimney caps, it may be worth taking a closer look at the roof. Not having visible proof of hail damage doesn’t mean it’s not there.
