Manufacturer warranty
This generally relates to the roofing product and is governed by the manufacturer’s written terms.
Workmanship warranty
This generally relates to installation work and may be provided by the roofing contractor. Terms can vary widely.
Read the actual documents
Ask for warranty documents before signing and review exclusions, registration requirements, maintenance obligations, transferability, and remedies.
Do not rely on the headline number
A long advertised term does not necessarily mean every component or type of failure receives the same coverage for that entire period.
Roofing Help USA note: This site focuses on roof replacement and new roof installation. It does not present Roofing Help USA as the contractor performing the work.
