The answer to 'how often to replace roof maintenance' is that most roofs need to be replaced every 20-25 years, depending on the roofing material and local climate conditions. Asphalt shingle roofs typically last 15-20 years, while metal and tile roofs can last 40-50 years or more with proper maintenance. Regular inspections and minor repairs can help extend the lifespan of your roof.
It's important to have your roof professionally inspected every 3-5 years to check for any damage or wear that may require repair or replacement. Factors like severe weather, poor installation, or lack of maintenance can all impact how long your roof lasts. If you notice any leaks, missing shingles, or other visible issues, it's best to have a roofing contractor take a look right away.
