The answer to 'how long does roof vent last' is that roof vents typically last 15-30 years, depending on the material and climate. Metal roof vents are the most durable, often lasting 20-30 years, while plastic or PVC vents may need to be replaced every 10-15 years. Proper installation, maintenance, and ventilation are key factors in maximizing the lifespan of your roof vents.
Roof vents are an essential component of a healthy roofing system, helping to regulate temperature and moisture in the attic. Over time, exposure to the elements can cause roof vents to deteriorate, leading to leaks, drafts, and other roofing issues. It's important to regularly inspect your roof vents and replace them when necessary to maintain the integrity of your roof.
