If there's an unfinished attic or crawl space below a leaky roof, finding the leak shouldn't be too hard. Climb into this space and look around with a flashlight it's easier to see a leak in the semidark, so don't turn on a light. When you find the leak, outline the wet area with chalk. If possible, push a piece of wire up through the leaky spot, so that it protrudes from the roof. This makes it easier to find the leak when you're working outside. If possible, repair shingles on a sunny day. A wet roof is dangerously slippery.
You can repair split shingles temporarily even if you don't have any flashing. Put a piece of cardboard in a plastic bag and then slide the bag under the shingles. You don't have to replace a cracked asbestos shingle if all the pieces are still in place. Pull out the obstructing nails and slide a piece of roofing felt or roll roofing under the shingle until it is behind the cracks. Drill holes for the new nails needed, then drive in the nails gently. Cover the nail heads with roof cement.
If black roofing drips tar down on shingles when you're patching, soak a rough rag or brush in kerosene and scrub the stains off right away. New asphalt shingles can be put down over old asphalt, wood, and roll roofing if it's only 1 or 2 layers. If it's in 3 layers, the old roofing must be stripped off. Cedar shakes, slate shingles, or tiles, however, must be taken off. If you want to replace a damaged shake and it doesn't come out easily, split it into several pieces with a hammer and chisel. Remove the pieces and extract the nails.
If the deck under old shingles is spaced sheathing, begin at the ridge so that debris does not fall through the spaces into the house. To avoid having a new looking unweathered patch in repaired shingles or shakes, take replacements from an inconspicuous area of the house and use new shingles or shakes on that spot. To make it easier to slide a new shingle up into place, round the back corners slightly with a sharp utility knife. Then lift the corners of the overlapping shingles and drive in a roofing nail at each corner.
Do not store asphalt shingles directly on the ground or on the roof overnight. Stack them on pieces of. When storing shingles, cover them with tarp rather than plastic, because moisture can condense under plastic. Stack shingles no higher than 4 feet. For emergency repair of a shingle, cut a patch to fit from a piece of sheet metal and slip it well under the shingle above the one you're repairing. Apply a coat of roof cement to the bottom of the patch, and tack in place. Cover the tack heads with cement. When you come back to do a more permanent repair later, pry up the patch.
