DIY Roof Shingle Repair
- 1). Identify roof shingles with edges that are curling and, apply the roofing sealant underneath the corners.
- 2). Press the curled shingle corners down immediately onto the sealant, and add continuous pressure by placing a brick on top of the shingles. Remove the brick after 24 hours.
- 3). Identify cracked shingles on the roof and lift the shingles to expose the underside. Place sealant on the roof underneath the crack, then press the shingle onto the sealant.
- 4). Place a line of sealant on top of the crack and smooth it down with a putty knife to complete the repair.
