A rippled or wavy asphalt shingle roof is not a good sign. It could indicate improper roof installation or other underlying issues, so you need to address it with immediate repairs.
Home Pro Exteriors identifies the following as the three primary causes of wavy asphalt shingles. We also share ways how to fix them.
During installation, roofers attach sheathing to the joists and trusses. Sheathing consists of wooden boards typically made of OSB or plywood, and it is used to attach to the shingles. If the sheathing is installed without a gap between the boards, rippling could occur because there is no space to accommodate expansion and contraction. To fix this issue, you’d have to redeck your home — which can be expensive. Make sure to discuss this with your roofing contractor when planning your roof replacement.
Misaligned and incorrectly measured asphalt shingles will expand and push against each other, creating a wavy appearance. That is why professional roof repair and replacement experts make sure they accurately measure and cut your asphalt shingles. In some cases, rippling occurs in poor-quality asphalt shingles.
To solve the problem, you may need to remove and replace your shingles. We highly recommend working with reliable and experienced professionals who will ensure proper roof installation.
If your new roof was simply laid over your old roof, it could result in the shingles’ wavy appearance. That is why roofing experts will often recommend the time-consuming yet effective process of a full roof replacement — which involves tearing off and replacing the old roof. That said, your roof will have to be stripped and reinstalled to fix the issue.
