Identifying roof damage under your shingles can be tricky. After locating the leaking point, you should start to see curled up or perhaps destroyed shingles. This can indicate water damage. When there is a leak, warped and deformed shingles start to appear. If the damage to your roof is not obvious, you need to call in a roofing contractor to find out what the real issue is. Sometimes it is much more complex and has to do with the interior of the roof. Check out roof.net in Great Falls for all your roof repairs.
