Over the past couple of months I have been writing about how to make your home more energy efficient. I am spending so much time on this topic because many people are looking for ways to save money and save our environment. Making sure that your home is operating at it’s maximum efficiency is just as important as making sure your car is running well. Since a home is the most expensive investment most people will have it only makes sense to keep it well maintained. Having proper roof ventilation is another way to make your home more energy efficient.
It is counter intuitive to think that having a hole in your roof would actually be more energy efficient, but it is. One of the most common forms of roof ventilation is ridge vent. Ridge vent is a space cut out of the ridge on the roof line where the warm air can escape. In order for this to work properly your home also has to have soffit vents so the cool air can come in through the soffit and push the hot air out through the ridge vent. Having proper ventilation is just one more component to having a leak free roof for many years to come.
It is never too late to add ventilation to your roof. Even if you have recently had your home re-roofed you can still add ventilation. For more information about this type of ventilation or to learn about other kinds give our office a call @ (405) 359-3951 and we will be happy to help you find the right fit for your home.

Believe it or not the best way to protect your roof from dry rot is to have ventilation in the attic. Proper ventilation ensures that your roof will live out its intended life span. When your attic space gets hot and humid, the warm moist air rises, unless it has a way to escape, the plywood (decking) can't breathe and this will cause your decking to start decaying. The shingles are attached to that plywood and if that plywood starts to decay then the shingles could loosen and even blow away leaving your home vulnerable to leaks. The failure of your plywood may also damage your insulation. Your attic needs to stay cool and have an exchange of air to prevent the dry rot.
A common misconception is that having ventilation is a bad idea in the winter and any ventilation should be covered or sealed during the cold months. Ventilation is important in the winter too because you don't want condensation to form on the decking. A great way to visualize this is the example of a cold soda can just out of the fridge. When you take the can out of the cold as it starts to warm up condensation forms on the outside of the can. Imagine that on the inside of your roof. Without ventilation that condensation will stay on the wood until it is absorbed. Over time this will cause dry rot and your roof and insulation will fail causing hundreds of dollars in repair costs.
