With hail and storm damage, you’ll see tiny granules of the roof missing. In due time, the roof damage may get progressively worse, which shortens the lifespan. Eventually the roof may end up leaking. Even if the roof has minimal damage, you have a valid insurance claim, which you need to file with your insurance company.
Roof damage caused by a hail storm may not cause the roof to actually leak for years, which is why it is critical to have somebody who’s qualified thoroughly inspect the roof sooner rather than later.
