What To Check After Roofers Installed New Roof? After your roofers have installed a new roof, it's important to perform a thorough inspection to ensure everything is done correctly. Check for any visible signs of damage, such as cracked or misaligned shingles, and ensure they are securely fastened. Inspect the flashing around chimneys, vents, and skylights for proper sealing to prevent leaks. Look for any gaps or loose materials in the roofing system. Ensure that gutters and downspouts are properly installed and directing water away from the house. Pay attention to the roof's slope to ensure it’s correctly pitched for water drainage. Finally, confirm that the roof looks uniform in appearance and that no debris is left behind. Regular checks after installation will help identify issues early and keep your roof in top shape.
