Roof and Attic Ventilation Guide

Ventilation is Important

Ventilation is crucial to a long lasting, healthy roof. Improper ventilation can not only shorten your roof’s lifespan, but it can also sometimes void the manufacturer’s warranty, making things much more costly when you have to fix them. The good news is there are a lot of options when it comes to attic and roof ventilation!

Types of Roof and Attic Ventilation

  • Ridge Vent
    Roof Ridge Vent
    This is ventilation that is installed at the peak (or ridgeline) of the roof. It allows hot air to escape the attic through a channel that runs the length of the vent. It is the most effective kind of roof vent because it simultaneously allows hot air from the attic to escape while the soffit vents intake cold air. To be eligible for this kind of venting, your roof needs to have the correct gable to square footage ratio (this is based on an industry standard calculation) and there must be soffit vents in place.

  • Soffit Vents

    Soffit areas in your house must have vents in order to allow the intake of cool air into your attic. Cool air is taken into the soffit vents and hot air is expelled through venting at the top roof through the ridge vent. Both soffit and ridge vents are necessary for the best attic ventilation.

  • Mushroom Roof Vents

    Named because of their resemblance to mushrooms, these are passive vents that don’t require electricity.

  • Turbine Roof Vents

    These vents also resemble mushrooms, but they contain a spinning turbine that moves by the wind to help expel hot air from your attic. They are also passive vents and do not require electricity.

  • Airhawk Roof Vents

    A passive rectangular vent with a round hole that help cool the attic. We usually install several of these evenly across the roof line near the top for the most effective venting.

  • Solar Fans

    These are vents that have solar powered fans in them. They are most effective in areas of the roof that get a lot of direct sunlight, and aren’t covered by trees.

A Final Word On Attic and Roof Ventilation

While these are the most common roof and attic ventilation options, there are a few other types that we can install depending on your home’s construction among other factors. It’s important to consult an experienced roofing contractor to help you choose the right ventilation option for your home. Having good airflow in the attic will prolong the life of your roof, saving you money and stress.
