After a hailstorm, you might walk around your property and assume that everything is fine because of the lack of visible hail damage. But you cannot actually know how much damage your roof has until you know what to look for and do your due diligence.
Check for Loose Granules
When your roof is struck by small pieces of hail, granules from your shingles become loose. They might not fall from your roof immediately, but they will eventually detach from your roof and become noticeable. This is especially common after a large rain storm. Hail may take as much as 10 years off the life of your roof.
Inspect Metal Roofs for Dents
If you have a metal roof, you may see small dents. These are likely the most noticeable after a good rainstorm and will also indicate the size of the hailstones. While metal roofs can often resist hail damage better than other roof types, you should still have your metal shingles repaired and replaced.
Check Cedar Shakes and Slate for Damage
Cedar shakes will splinter, and the hail might create light intents. Slate can develop cracks or chips, which can allow water to enter through the roof. If you aren't sure if you should replace your roof, you should contact a residential roofing professional.
Inspect Metal Vents and Flashing
Your metal vents and the flashings on your roof might sustain damage. In order to inspect these components, you must get on the roof. This is very dangerous, so make sure to have someone helping you, and wear a fall-prevention harness.
Look for a Second Opinion
If you are not sure what to look for, make sure to contact a professional roofing contractor who has experience with hail storms. If you don't repair your roof, you might suffer from leaks. Also, you won't be able to report the hail damage to your home insurance policy after too much time has passed. If you do have an insurance provider send a roofing inspector, you are best off getting a second opinion. Insurance adjusters are often unwilling to pay for hail damage.
The roofing contractor will check your roof for any missing shingles. They might also discover holes in the protective cover of your roof or material deterioration. They'll look for warning signs of water leaks and damage. You may also have a weakened roof seal or an exposure of your fiberglass matt.
