“Roof vent” is a common term often applied to everything from plumbing stacks, to even furnace vents and dryer exhausts. However, as we define roof vents we are specifically referring to the vents designed to remove hot stagnant summer air and moisture during winter months out of your attic. To see the different types of roof vents available, check out our blog post What Types & Styles of Roof Vents Are There?
Roof vents are critical in determining the life expectancy of your roof, utility costs and preventing interior damage from condensation and moisture.
This is a good question! All throughout the greater Atlanta area we see homes with mixed ventilation types. To find out more, read our article Can I Mix Different Roof Vent Types?
For most, summer signifies more time outside; ice cream, time with the kids, baseball, a return to the golf course and trips to the pool, but it also means the return of unrelenting heat. That’s why most homes are shielded by attic insulation, but if your attic isn’t vented then you are making your air conditioner and insulation work harder than necessary. After taking into account the sad fact that most Atlanta homes are under insulated, the strain hot temperatures place on AC units is severe.
Georgia summers, specifically the greater Atlanta area, can see asphalt shingles reach average temperatures of 125° F or more – some reports exceeding 150° F! This heat transfers from the shingles into your roof deck and lingers in the attic turning it into a veritable oven.
By installing a well-designed combination of soffit vents (intake) and roof vents (exhaust), fresh air can circulate through your attic and heated air can effectively escape. This will lower the burden on your air conditioner, insulation and your power bill.
So venting your attic in the summer makes sense, but how does opening it to cold air in the winter help?
In fact, the importance of cooling your attic in the winter has less to do with comfort or utilities, but everything to do with removing harmful moisture from your attic and preventing water damage to your home. The goal is to keep the air temperature below your roof deck, or inside your attic, as close as possible to the temperature above it, or outside of your home.
