Ventilation is one of the most important components of your roofing system. Making sure that you have a properly ventilated roof is what will increase your energy efficiency, eliminate ice dams, as well as prevent dry rot. When it comes to replacing your roof, knowing exactly what expectation to set for your installation comes from staying informed!
Why is ventilation in your roof system so important?
Increasing Your Energy Efficiency.
Who doesn’t want to save on their electric bill? In the summertime, when you have hot, stagnant air sitting in your attic, your home will not retain the cold from your air conditioning as effectively. This will reduce your energy efficiency and ultimately end up costing you and your family money on the electric bill. In the winter time, this hot air will rise and seep through your roof deck creating ice dams.
Preventing Ice Dams!
When your roof is not properly ventilated, the hot air in your attic is forced to expel through your roof deck. In the winter time, this will melt the snow on your roof just for it to re-freeze when it reaches the cold of your eaves. This process will damage your shingles and leave your roof vulnerable to water damage.
Dry rot is a nasty and difficult situation to address especially when it is affecting your roof deck and rafters. Without proper ventilation, this type of fungi will thrive from the higher temperatures and stagnant air. Once discovered, it is important to address the problem quickly as all of the affected wood needs to be removed and replaced before it spreads to other areas of your home. This problem can be serious and expensive!
