Renovations, repairs, and upgrades come with their own warranties — from the contractor's workmanship guarantee to the manufacturer's coverage on materials. Know what's protected before you start.
Most reputable contractors offer a 1-2 year workmanship warranty covering installation defects. This is separate from the product warranty. Always get it in writing before the project starts, and verify the contractor is licensed and insured in your state.
Materials purchased for renovation projects carry their own manufacturer warranties. Roofing shingles (25-50 years), siding (20-40 years), windows (10-20 years), and flooring (15-25 years) all have separate coverage. Registration is often required within 30-60 days of installation.
DIY installation can void product warranties that require professional installation. Using non-approved materials or skipping permits may void both contractor and manufacturer coverage. Always keep receipts, contracts, and photos of completed work.
