- After roofers install a new roof, start by checking for proper shingle alignment and uniform appearance. Make sure flashing is securely installed around chimneys, vents, and skylights. Inspect gutters and downspouts for debris or damage during installation. Check the attic for signs of light leaks or water intrusion. Ensure ridge vents and other ventilation systems are in place and functioning. Confirm that all roofing materials match what was agreed upon in the contract. Look around the property for leftover debris or nails. Finally, request a warranty and final inspection report from the contractor.
