The answer to 'when to replace roof maintenance' is that you should generally replace your roof every 20-30 years, depending on the type of roofing material and the condition of your roof. Asphalt shingle roofs typically last 15-20 years, while metal and tile roofs can last 40-50 years or more with proper maintenance. Signs that it's time to replace your roof include curling, cracked, or missing shingles, leaks, and excessive granule loss.
Regularly inspecting your roof and addressing any issues early can help extend its lifespan. It's also important to have your roof professionally inspected every 5-10 years to identify any potential problems. Replacing your roof before it fails can help prevent costly water damage to your home.
