It is advisable to inspect your roof for damages after a storm; the inspection is particularly necessary in case of an aging roof, a strong storm, or both. Conduct the inspection both from inside and outside the house for maximum effectiveness. Here are some of the specific signs of roof damage to watch out for during the inspection:
Inside the House
Your roof deck may begin sagging after a storm if the supporting roof structures have been damaged by the storm. This may be the case, for example, if a tree branch has fallen on the roof or if there is more snow on the roof than it can bear. Note that the sagging will only be visible to your naked eye in extreme cases.
Sunlight Passing Through
Sunlight passing through the roof means there is a crack or a hole in the roof. Such holes or cracks are risky because they can let water through the roof and cause further damage. Holes on the roof may be caused by falling tree limbs, displaced shingles, and uprooted nails, among other things.
Streaks, Stains or Leaks
You should also look for streaks or stains on the ceiling or upper walls; both of these signal a roof water leak. In extreme cases, you can actually see the water leaks, especially if there is still water on the roof.
Outside the House
Once you are done peering up the attic, it's time to take the inspection outside and look out for the following:
Debris on the Roof
Medium and large debris on the roof, such as fallen limbs, twigs, and windblown debris should be visible from the ground. These may not present an immediate danger to your roof (well, except large limbs), but they can cause roof algae growth and water damage in the long run.
In some cases, storm damage may also leave you with missing shingles, which you may notice around the house. Other signs of physical damage to watch out for include bent roof shingles or wind lifted parts of the roof.
Shingle Granules around the Downspouts
In the case of a hailstorm, you should also look out for the telltale signs of shingle granules loss. You should suspect granule loss if you can see small shingle granules around the downspouts. This is bad news for your roof because the granules provide a protective layer over the shingles; without them, the shingles become susceptible to physical and weather-related damage.
Hopefully, your roof damage won't unearth any nasty surprises. However, you need to consult a roofing contractor as soon as possible if you do suspect damage; you need to fix it before the next storm arrives. Contact a local roofing company like Amick Roofing Inc if you feel that your roof needs extra repair and attention.
