How Much Soffit Ventilation Do I Need?
July 20, 2022
Soffit ventilation is one of the best ways you can preserve the integrity of your roof and address problems with excessive hot/cold air entering your home. Of course, like anything else in construction, there’s a certain amount you need, and going beyond that isn’t worth the cost.
We’ll help you understand this ventilation concept and make it easier to see how much of it you really need to balance airflow in your house.
What is Soffit Ventilation?
Soffits refer to architectural fixtures that go underneath the roof underhang. They have both interior and exterior purposes, including “under arches” that are popular on home exteriors like arched doorways or porticos. There are many variations of soffits.
In roofing, soffits are one of our favorite ways to install ventilation. Most of the time, roof ventilation works one of two ways: soffit vents or rooftop vents. The latter involves trying to introduce air into your home from its highest point. Soffit vents bring in the air at a much lower spot.
Soffit ventilation fixtures can come from a variety of material sources such as wood, fiber cement, or aluminum. You actually get better airflow and ventilation by positioning air vents in underhang soffits.
How Much Soffit Ventilation Do You Need?
Despite the fact that these are not mere “decorations,” many homes don’t even have soffits. However, as we see how much of a difference it makes with ventilation, we recommend getting adequate coverage. This usually comes out to approximately one square foot of ventilation for every 150-square feet of attic space.
When should you replace soffits? There’s no hard-and-fast rule, but we generally recommend switching them out if you notice hot air in your attic or upstairs areas. Granted, cold drafts could come from other problems, too. So, you want to get an inspection to rule out all possible issues.
What does soffit installation typically cost? The good news is that it’s not terribly expensive. For just the cost of materials, hardware stores sell 12-foot sections of soffits for anywhere between $10 to $30. That makes it a pretty cost-effective investment in light of lower energy bills and roof protection.
Don’t forget that if you replace your roof with GAF shingles, purchasing a few extra peripherals can actually qualify you for a lifetime warranty. In other words, it pays to get adequate soffit vents and other protective equipment to obtain better manufacturer warranty coverage.
