Where do you put a vented soffit?

Space the soffit vents evenly around the bottom of the low sides of your roof. There are several different types of soffit vents available including continuous, circular, and perforated vents made for vinyl siding.

How much of your soffit should be vented?

Most professionals recommend one square foot of ventilation for every 150 square feet of attic area. This will help you determine how many soffit vents you need. For example, a 15′ x 40′ attic would have a total area of 600 square feet; divided by 150 equals 4 square feet of total ventilated space needed.

How do you improve soffit ventilation?

5 TIPS FOR IMPROVING YOUR ATTIC VENTILATION

  1. Assess Your Needs. Before you make any changes, it’s important to determine if your attic actually needs additional ventilation, and if so, how much.
  2. Insert Roof Vents.
  3. Add Soffit Vents.
  4. Install Gable Vents.
  5. Use Fans to Improve Airflow.

Do soffits lead to attic?

Soffit vents are roof ventilation devices installed underneath the eaves of a roof that extend past the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter into an attic creating air flow.

How do I know if my soffit vents are working?

There are two easy ways to check this. If you can get into the attic when it’s dark (or bring a flashlight but then turn off the attic lights), see if you see light when looking into the eaves – if so there were openings cut. If not there were either no openings or they are blocked.

Can an attic have too much ventilation?

It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.
