If an older roof has multiple layers of shingles, replacement can require substantially more tear-off labor and disposal than a roof with only one layer. The Lane House guide estimates that removing a second layer can add roughly $50–$100 per roofing square to a project.
Knowing what's already on your roof is an important part of creating an accurate estimate. If you're considering roof replacement in Mehlville or St. Louis South County, call Lane House Roofing & Exteriors to have your roof professionally evaluated.
