Uneven shingles and bulges after new roof replacement
New roof replacements sometimes show bulges or shingles that fail to lay flat, signaling potential issues with installation or underlying deck structure. When contractors leave these irregularities unaddressed, homeowners are left questioning the quality of the work and whether it compromises the roof's integrity.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
- 1Accepting the roofer's explanation that the issue is due to pre-existing structural sagging rather than a flaw in the new roof work.
- 2Negotiating a price decrease to cover replacing the entire roof
- 3Contacting the contractor who performed the work to have them fix it under their company warranty
- 4waiting for more heat to see if they seal
- 5inspecting individual shingles to see if heat will help
- 6Accepting the installer's assurance that it is not a problem.
