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 component of a home's roof system, providing important ventilation to the attic space. They are made from durable materials like aluminum or plastic and are designed to withstand the elements and resist damage over time.
With regular inspections and any necessary maintenance or repairs, a ridge vent can continue functioning effectively for decades. However, factors like severe weather, improper installation, or lack of maintenance can reduce the lifespan of a ridge vent. It's important to have a professional roofing contractor inspect the ridge vent periodically and make any needed repairs to ensure it continues to perform as intended.
