Roofing warranties come in two main types: manufacturer (material) and workmanship (installation). Knowing the difference and the fine print helps you get the most from your investment.
Manufacturer warranties
These cover defects in the roofing materials—shingles, metal panels, membrane, etc. They often last 25–50 years depending on the product. Many are prorated: full coverage for the first years, then decreasing. They usually require installation by a certified or approved contractor and proper ventilation. Failure to follow requirements can void the warranty.
Workmanship warranties
These are offered by the installing contractor and cover installation errors—e.g. improper fastening, flashing, or sealing. They typically run 5–10 years. Get the terms in writing and keep your contract and any warranty documents.
What to watch for
Some manufacturer warranties require periodic inspections or specific maintenance. Transfer fees may apply if you sell the home. Exclusions often include acts of God, foot traffic damage, or modifications. Read the documents and ask your roofer to explain anything unclear.
