When it comes to your roof, the shingles themselves are not the only thing you need to be concerned about. You also need to know about roof ventilation to keep the roof in good shape. If you are completely unfamiliar with roof ventilation, here is what you need to know about it.
Roof Ventilation Methods
There are several methods that can be used to ventilate a roof, with each having their own advantages. Many homes use soffit and ridge vents, which provide a way for air to enter and exit your attic. The ridge vents will be found at the peak of the roof, and their role is to release the hot air and moisture from your attic. The soffits bring in the outside air to help circulate it through the ridge vents.
Attic fans are another way that you can cool down your roof while also cooling down your home. They also are referred to as whole-home fans, since they will suck the air through your home and push it out through the roof. This fan serves a dual purpose, which is why it is a popular choice for some homes.
Gable vents are those grills that you see on the sides of homes located underneath the roof's peak. They don't allow water or snow to come into your attic, but they keeps the attic cool by pushing air through the vents from one side to the other through a cross breeze.
Roof Ventilation Advantages
By having a well-ventilated roof, you'll notice that you have fewer issues in the winter with ice dam formation. This is when the air inside the attic gets hot and causes snow to melt then freeze lower on your roof to damage shingles. By not allowing all that hot air to build up, you should never get to the point where snow is melting on the surface of the roof.
A cool roof also helps you reduce your cooling costs during the winter. If the roof isn't hot, that heat is not going to make the rest of your home feel hot as well. You'll end up using your home's air conditioner less and spend less on energy as a direct result.
Now that you know more about roof ventilation, you should understand why it is so important for your home. Reach out to a local residential roofing contractor if you feel you need help fixing roof ventilation problems.
