It’s important to pay attention to the effectiveness of ventilation in the roof of your home. Poor roof ventilation can create a variety of problems including HVAC inefficiency, ice dam development, and leaks in your home’s ceilings.
Fortunately, there are numerous things you can do to improve roof ventilation. The following are five things that can be done to improve roof ventilation in your home:
1. Insulate your attic adequately
Insulation in your attic is essential to ensuring that your roof is properly ventilated. The insulation you should use in your attic should be R-38. This type of insulation equates to roughly eighteen inches thick of an insulating material.
You should not only have adequate insulation installed, but you should also periodically have your attic insulation inspected to make sure that it is staying in good shape. Insulation can become damaged over time so that it doesn’t function as effectively as it should. In these cases, insulation should be replaced.
2. Place vents at your roof eaves
You need to have roof vents installed in order to properly vent your roofs. Along the eaves of your roof, you should have soffit vents installed. Soffit vents typically function by allowing air to flow into the roof.
3. Place vents at the peak of your roof
It’s important to include roof vents at the peak of the roof in addition to soffit vents at the eaves. Different types of vents along the peak of the roof include ridge vents, hood vents, and turbine vents. Air exits the roof through these types of vents. A turbine vent works by using wind power to pull air out of the attic through suction.
If air flow through your home is inadequate, you may need to have more venting installed to address the issue.
4. Inspect vents periodically to make sure they are not clogged
Over time, vents can become clogged. Clogged vents will no longer function effectively. As air flows through vents, debris like dust and other particles can become trapped within vents and build up over time. Fortunately, it’s a fairly easy task to clear debris from vents and make sure that air is flowing through them smoothly once again.
5. Calculate vent area carefully
How much vent area you need will depend on the square footage of the attic floor of your home. As a general rule, you can consider that you’ll need to have a square foot of venting area built into your home for each 300 square feet the floor of your attic extends.
