Step 1
See "Setting up ladders and equipment," How to Repair a Cracked or Split Wood Shingle, to set up ladder safely.
-
Step 2
Tap a large, flat pry bar under the damaged shingle just above the gap between tabs until you hit a nail. Center the tool's nail-pulling slot on the nail, tap the bar in a bit more, and press down on the other end to pry the nail partly out. Then place a block of wood under the bar just down the roof from the nail to act as a fulcrum, and pry out the nail the rest of the way.
-
Step 3
Continue to remove all nails that secure shingles directly above the damaged shingle and that also penetrate the top edge of the damaged shingle.
-
Step 4
Pull out the damaged shingle and slip in the replacement (see A).
-
Step 5
Align the replacement shingle and lift the shingle above it as needed to nail the new one into place with 1-inch (2.5-cm) roofing nails (see B).
-
Step 6
Replace any nails that you removed from the shingles above.
-
Step 7
Dab roofing cement over all the nail heads that you couldn't remove without breaking the shingle, as far up as it should go (just above the notch).
-
Step 8
Use a putty knife to spread a little roofing cement under each shingle tab that you lifted during the repair, and press each shingle down to adhere it to the one below.
