Roofing Warranties Explained: What Every Homeowner Should Ask

The Three Warranties in Every Roof Install

• Manufacturer material warranty — covers the shingles themselves
• Manufacturer system warranty — extended coverage when a certified installer does the job
• Contractor workmanship warranty — covers labor & install errors

Questions Every Homeowner Must Ask

• What voids the warranty? (unlicensed repairs, walking on roof, satellite dish install)
• Is the labor to remove and re-install shingles covered, or just the materials?
• Is the warranty transferable to a new owner if I sell?
• How long is the workmanship guarantee — 1 year or lifetime?
• What is the claim process — who inspects and pays first?

What 'Lifetime Warranty' Really Means

For most manufacturers, 'lifetime' means 25–50 years, and coverage decreases each year. A 30-year warranty typically covers 100% of materials for the first 10 years and drops to 20% by year 20.
