4 Problems Caused By Poor Attic Ventilation

Attic ventilation is an important part of keeping your home safe and structurally sound. It doesn’t just play a role in airing out the rest of your home and regulating comfort level; it’s also integral in keeping your roofing healthy. Knox’s Construction presents four problems caused by poor attic ventilation.
 


The Deterioration of Your Roofing

Poor attic ventilation causes excessive moisture to build up on your roof. During summer, the lack of air means your roof dries up faster. The result is an unhealthy roof that will have a weaker underlayment, which translates to weaker resistance to water intrusion.


Eventually, the shingles on your roof will start to suffer as well, which will lead to a surprise roof repair. If you want to keep your roofing system healthy, then make sure your attic has ample ventilation. 


Higher Energy Bills

The lack of proper attic ventilation translates to higher energy bills. The trapped heat in the attic can escape from only two points: through the roof or down through the house. This means you’ll have to turn on the air conditioning more often, and that means higher energy bills.


Sagging Gutters

This can be caused by a problem with the hardware that secures your gutters to your fascia. The hangers might be too old, or they might be spaced too far apart. It can also be caused by fascia deterioration. We’ll fix this by installing new hangers or by replacing your fascia.


Rusting on The Roof

Excess moisture that eventually goes upwards to the roof will negatively affect the metal components of your roofing system, such as the flashings. The flashings are responsible for protecting your roof’s most vulnerable parts from water intrusion. When rust begins to develop, flashings and other components can’t perform their job as well, and leaks will become more frequent. Rusting is also dangerous if you have a completely metal roof.


Ice Dams

Finally, the lack of ventilation on the roof will cause ice dams to form during winter. When hot air escapes through the roof, it goes upwards and melts the snow on the top part of the roof. The melted snow then refreezes once it reaches the edge of the roof, creating ice dams.
