The answer to 'how often to replace roof maintenance' is that most roofs need to be replaced every 20-25 years, depending on the type of roofing material and local climate conditions. Asphalt shingle roofs typically have the shortest lifespan of 15-20 years, while metal, tile, or slate roofs can last 40-50 years or more with proper maintenance.
Regular roof inspections and preventative maintenance are key to extending the life of your roof. This includes clearing debris, fixing any leaks or damage, and ensuring proper ventilation. Homeowners should have their roof inspected by a professional roofing contractor at least once a year, and after any major storms or weather events.
