Roof vents are more than just oddities on your roof. They ensure that air circulates throughout the attic and properly exits your home. Many homeowners assume that covering them during the winter is a good idea unaware that it’s not only unnecessary, it may even put your home at risk.
The Thomas Roofing Company, your roofing and gutter installation expert, explains why you should never cover the roof vents in winter.
The Risk of Covering the Vents
When you cover the vents, you’re unknowingly trapping moisture inside the attic. This trapped moisture will cause mold to form and proliferate, which can prove troublesome to get rid of and can even become a health risk.
Covering the vent also makes the attic extra warmer than it’s supposed to be. This may seem like a benefit at first, but it puts the roof at risk. Warm air in your home escapes upwards through the attic and the roof vents, but if the vents are blocked, they remain in the attic.
This trapped warm air will eventually heat up the roof, causing the snow on its surface to melt and then refreeze on the edges near the gutters forming an ice dam. These don’t just clog the gutters, they put extra weight on the roof and can even loosen the shingles. This risk is the reason why your preemptive roof repair should include ensuring the roof vents are free of any clogs and blockages that may affect its operation.
Winter and the Roof Vents
The cold winter conditions cause the vents to let in cold air into the attic, making the space colder than usual. Apart from the chill in the air, the cool air entering from the vents won’t negatively affect your energy usage nor will it cause any damage.
The solution to a cool attic doesn’t lie with the roof or the vent but with the insulation. When the attic is properly insulated, it will stay warm and cosy even if there’s a bit of cool air entering from the vents.
