The answer to 'how long does ridge vent last' is that a properly installed and maintained ridge vent can last 20-30 years or more. Ridge vents are a crucial part of a home's roofing system, helping to improve attic ventilation and prevent moisture buildup. They are made of durable materials like aluminum or plastic that are designed to withstand the elements and resist damage over time.
However, the actual lifespan of a ridge vent can vary depending on factors like the quality of the installation, the local climate, and how well the vent is maintained. Proper maintenance, such as regularly clearing debris and ensuring the vent is securely fastened, can help extend its lifespan. If a ridge vent becomes damaged or worn, it's important to have it repaired or replaced by a professional roofing contractor to maintain the integrity of the roof.
