shingles age the corners may start to curl
It is really good that you are addressing
bange this problem, even if it appears to be a small one. Most shingles will last about 20 years, but any signs of damage, wear or curling could lead to water seeping under the shingles and rotting the wood beneath. Replacement of a damaged shingle will prevent further damage and costly repairs. Repairs to shingles can take three forms; gluing down a shingle that has begun to curl, repairing a cracked shingle or replacing a damaged shingle. Any of these repairs are best done on a warm afternoon when the shingles will be more pliable.
As shingles age the corners may start to curl. This can easily be addressed by applying a bead of roofing sealant under the shingle with a caulk gun. Use a brick or similar weight to keep the shingle in place until the sealant dries, about 24 hours.
Shingles that are cracked don't have to be replaced. You can repair a crack in a shingle by applying a thick bead of roofing sealant with your caulk gun to the underside of the crack. Place a second bead over the crack and spread it evenly with a small putty knife. Now look in the gutter for some of
bange the small colored grains that have washed down from the roof. Sprinkle a small amount over your sealant to "hide" the repair.
