How to Replace Roof Shingles
To replace roof shingles, you will need to access the nails at the top of the target shingle. Roof shingle replacement is best carried out on a day with moderate temperatures. Hot temperatures make the sealant hard to separate; cold climates could cause the shingles to fracture.
Carefully peel the shingles back to expose the first layer of nails damaged row. You may need to peel back shingles to the right or left of the target shingle as well, depending on the layout.
Once exposed, pry out the first layer of nails holding the damaged shingles in place. Prying the nail straight from the shingle’s surface can damage the grained texture of the shingle. It is better to lift the shingle and the nail together.
You will then have to repeat the process for the bottom half of the shingle, prying the shingle and row of nails out together. Once the bottom half of the shingle is free (after removing two rows of nails in the target shingle), you can remove it. There are approximately eight nails in each shingle, four on each row. You will then have to peel the shingle from the sealant across its lower half.
Inserting the New Shingle
After removing the damaged shingle, insert the new shingle into place at the top half. Once in line, you can hammer nails into the top section to lock it down.
Take the roof shingle replacement and slide it into place. The replacement shingle must be the same type and size as the damaged shingle. Nail the new shingle down in the same locations as the old nails.
For the last step, you will have to replace the sealant bonds that you broke when removing the old shingle. Use a few (at least three) spots of asphalt plastic roof cement under the new shingle’s flaps to finish the seal. Usually, new shingles will bond to the layer below with the sun’s heat, but the sealant will keep your home dry until then.
Remember to seal any surrounding shingles that were pried away to replace the damaged one.
