Household Repairs Holes, cracks. Slip a piece of aluminum or copper flashing metal up under the shingle over the hole and hold it in place with asphalt roofing cement. The metal must be long enough to extend well up under the overlapping shingles.

Shingles rotten, badly damaged. Loosen overlapping shingles. Split defective shingle and pull out pieces. Slip a hacksaw blade up under overlapping shingles and cut nails which held defective shingle. Insert a new shingle. Put one or two dabs of asphalt roofing cement under this to hold it.

Leaks in a closed valley. (A closed valley is one in which shingles come together instead of being separated by an open strip of flashing material.) Cut 12"- or 15"-wide aluminum or copper flashing metal into squares and bend into equal triangles. Push the metal up under shingles as far as possible. If a series of metal patches are required, work from the bottom of the roof up.
