Effective attic ventilation provides year-round benefits for all roofing system types. It protects against damage to material and structure of the roof. In any season, bad ventilation can have negative effects on your roof.
With poor ventilation, summer temperatures can cause a massive heat build-up in the attic. The combined heat and moisture can lead to many problems, including damage to roof decking and shingles, which can deteriorate prematurely and shorten the life expectancy of a roof. Not only can poor ventilation have negative impacts in the summer, but also in the winter.
In the winter, moist warm weather from lower areas of your home can rise into the attic. This leads to the warm moist air condensing to the rafters, nails, and attic side of the deck. This excess water can cause many problems, such as deck swelling, buckling of shingles, and deck rot.
Another problem from poor ventilation in the winter is the formation of ice dams. The warm temperature in the attic combines with the sun’s heat causing the snow to melt and refreeze at the eaves and gutters. This cycle can cause damage to the roofing due to the build up of water. It can build up under shingles, fascia boards, and soak roof decking. Having proper ventilation will help diminish this problem. Proper placement and installation of vents assures a continuous flow of air that moves in the desired direction. This can play a critical role in preserving the life of your roof performance, especially with the change of weather.
