Hail Damage
Hail leaves round "bruises" — impact points where granules are knocked loose and the shingle's reinforcing mat can fracture, sometimes exposing the dark asphalt underneath. A hail-hit roof usually doesn't leak right away, which is why the damage often goes unnoticed.
Why it matters: those fractures quietly shorten the roof's service life — and storm claims are time-limited, so the sooner damage is documented, the more options you have.
