The answer to 'how often to replace ridge vent' is that ridge vents typically need to be replaced every 15-20 years, depending on the climate and environmental conditions. Ridge vents play a crucial role in providing ventilation for your attic, helping to regulate temperature and prevent moisture buildup. Over time, the materials in the ridge vent can deteriorate due to exposure to the elements, leading to reduced effectiveness and potential leaks.
It's important to regularly inspect your ridge vent and look for signs of wear, such as cracking, warping, or missing pieces. If you notice any issues, it's best to have a professional roofing technician evaluate the vent and determine if replacement is necessary. Replacing the ridge vent can help improve the energy efficiency of your home and extend the life of your roof.
