How to Repair Composition Roof Tiles That Are Warped

Repairing warped roofing tiles will prevent roofing leaks and damage.

Asphalt shingles are also sometimes called composition roof tiles. Time, heat and adverse weather can cause these roof tiles to warp and curl. In most cases, the corners of the shingles will curl. This makes the shingles more susceptible to other damage. Repairing or replacing warped shingles can be done in an hour or two. If you decide to replace the warped tiles, match the tiles as closely as possible to the existing shingles.

Things You'll Need

• Flat pry bar
• Composition roof tiles
• Hammer
• Roofing nails
• Roofing sealant

Instructions

1. Locate the composition tiles that warped and curling. Walk along the roof to find the tiles that need to be repaired or replaced. Walk carefully so you do not catch any edges of the shingles and damage them more.

2. Lift the bottom edge of the tile gently to expose the roofing nails that hold the shingle below in place. Remove the roofing nails from the warped roof tiles by sliding a flat pry bar under the nails and popping them out of place.

3. Remove the roof tile from the roof. Work carefully so you do not damage any of the surrounding shingles.

4. Slip a new composition roof tile into place where the old shingle was located. Gently lift bottom portion of the shingle on top of the new shingle. Nail the new shingle in place with roofing nails.

5. Tiles that are only slightly curled can be fixed in place by applying a small amount of roofing sealant under the shingle. Set a brick on top of the tile while the sealant dries completely.
