How to roof repair asphalt shingles

1. Save a torn shingle by applying a layer of roofing cement on the back of each torn section with a putty knife. Press the pieces into position so the cement bonds between the pieces and also sticks them to the shingle beneath them. Hammer roofing nails along the repair to hold it in place.
