Introduction
Buy roofing cement in caulking tubes to seal minor cracks and holes and glue down curled shingles. If you have a larger job, buy the roofing cement in larger containers.
If the damage is extensive, replace the shingle, as shown here. When working with asphalt shingles, wait for a warm day when the shingles will be flexible and therefore easier to work with.

Asphalt shingles can look like
wood, but last longer. Still,
you should inspect yearly
for damage.

1. Remove the bad shingle
Loosen nails in the shingle above by slipping a flat shovel underneath. Pull the nails with a pry bar and remove the bad shingle.
|
|
|
2. Insert a new shingle
Remove 1 inch from the top edge of the new shingle and slip it into place under the shingle above. Note the positions of the four nails.

3. Fasten with nails
Try to drive in new nails through the holes left by the old ones. If you cannot, carefully seal the old openings with roofing cement.

|
4. Seal the nailheads
Coat the nailheads with roofing cement, then firmly press the upper course back into place. Weight it down, if necessary.

An alternate approach
You also can back up a damaged shingle with a piece of metal flashing. Secure the flashing with roofing cement and nails under the shingle.
