Attic Ventilation

Attic ventilation is critical to getting the most life out of the roof covering.  Attic ventilation also play a large role in keeping the home cool in the summer, and the prevention of condensation and Ice Dam problems in the winter.  Attic ventilation is an important part of the roof system. The 3 components of the roof system are Roofing Material, Attic Ventilation, and Attic Insulation.  Attic Ventilation is a key component in this system.


Attic ventilation is a simple concept.  The fresh, outside air should enter the attic preferably on the lower part of the roof, and then exhaust the hot or moist air near the upper part of the roof.  It’s best to have 50 to 60% of the vents low and 40 to 50% of the vents as high as possible.


3 Things You Should Know about Attic Ventilation

1. An improperly vented attic can reach a temperature of up to 160 degrees when the outside air temperature is in the 90s. Proper ventilation can reduce the attic temperature by as much as 60 degrees.


2. An under ventilated attic will “cook” asphalt shingles, and cause them to prematurely fail, this will void manufacturers warranties.


3. A properly ventilated attic will make the house cooler, and cost less to Air Condition.

During winter months, proper ventilation prevents moisture from getting trapped in the attic and causing problems.

attic ventilation during summer months
During summer months, proper ventilation cools and reduces the heat penetrating the home, through the attic.


Attic Exhaust Vents

There are many types of vents used to exhaust attic air. The important thing is to not incorrectly mix too many vents of different types. This is often done by overloading the upper roof with vents, and not providing enough air inlets. The term for this is called, “short-circuiting the ventilation”. This can actually cause the attic to become hotter! Click here for more: Fans and Ventilation


Slant Back Roof Vents have closely spaced louver openings allowing for exhaust air.

Solar Powered Attic Fans move a tremendous amount of air and have almost silent operation.

Ridge Vents are a great way to vent all attics and the only way to vent attic cavities on a vaulted ceiling. Ridge vents help prevent snow from blowing into the attic.  Ridge Vents are never allowed below a pitch of 4/12!

Wire Powered Attic Fans have a control box that turns the fan on at a set temperature, or if moisture is in the air.


Gable Vents

Gable vents are another way to vent an attic. However, the usually don’t prevent enough ventilation on their own. The best way to get adequate ventilation with gable vents is to install an electric gable vent fan at one end and create an “air tunnel”.


Air Intake Vents


Soffit Vents

Soffit vents are installed into the underside of your home’s eaves (soffit). These vents allow fresh air from outside to be drawn into the attic.

Eave Vents

Eave Vents are the simplest way to vent a home without proper soffit vents.  These vents should be installed on both sides of the house and should run the entire length. Eave vents must also be installed above any insulation.
