After your new roof is installed, start by visually inspecting it from the ground. Look for uniform shingle color and alignment. Check the gutters and yard for leftover nails or debris the crew may have missed. Make sure flashing is securely in place around chimneys, vents, and skylights. Inspect the attic for any signs of light coming through or water stains. Ask your roofer for a final walkthrough and a copy of the warranty. Verify proper ventilation has been maintained. Lastly, confirm that all agreed-upon work was completed as stated in your contract. Visit: https://managemyroof.com/blog/what-to-check-after-roofers-installed-new-roof/
