The answer to 'how to maintain roof installation' is to regularly inspect, clean, and repair your roof to ensure it continues to protect your home effectively. This includes checking for any loose, damaged, or missing shingles, clearing debris from the roof and gutters, and addressing any issues promptly to prevent further damage.
It's recommended to inspect your roof at least twice a year, in the spring and fall, and after any major storms. You can do a visual inspection from the ground, but for a more thorough inspection, it's best to have a professional roofer take a closer look. They can identify any potential problems and provide recommendations for maintenance or repairs.
