What is Attic Ventilation?

  • The process of supplying a continuous supply of air through the attic
  • 50% intake/50% exhaust
  • Exhaust must be at least 3 feet higher than the intake system
  • Intake should be under eave
  • Exhaust should be near or at peak

  • In the summer, good attic ventilation reduces heat buildup. That cuts cooling costs and prolongs shingle life. In the winter, warm, moist air seeps into the attic from the living space below. Good ventilation allows the heat and moisture to escape. That keeps your attic dry and reduces ice dams.

    There are several options when it comes to ventilating your home:


    Wind Turbines

    exter braced windturbine All aluminum rust-free construction. Wind Turbines Reduce energy bills. Permanently lubricated upper and lower ball bearings ensure that wind turbines offer long life and no maintenance.


    Technically, wind turbines aren't a fixed vent system because they use a moving part to help exhaust air from an attic. That moving part consists of a series of specially shaped vanes that turns wind force into a rotary motion. As the spinning vanes gain velocity, they create an area of low air pressure. That low pressure, in turn, pulls air from an attic.


    Solar Attic Fans


  • Cool your home with free power from the sun
  • Save on monthly utility bills
  • Increase the life of your roof
  • Reduce wear and tear on your air conditioner
  • Increase the value of your home

  • Unmatched in quality and performance. Designed for greater cooling capacity and durability than competitive products, Attic Breeze delivers up to 1550 CFM of cooling performance, more than any residential solar powered attic fan available.

    UltraFlo design technology is the proprietary fan design technology developed by Attic Breeze which allows our products to move a maximum amount of airflow for a minimum amount of energy input.

    Soffit Vents

    soffit ventThe best place to install intake vents is in or near the roof eave or soffits. That location provides two key advantages:

    1. The Soffit vents are better protected from rain and snow infiltration. Vents mounted in the eave provide almost total protection.
    2. Usually, when undereave vents are placed on both sides of a roof (as they should be), there's always an equal distribution of high and low pressure areas.

    Too much of a bad thing!

    Here is a great example of poor ventilation. There are two static vents on the top row with an old electric power fan that probably doesn’t work in the middle. In order to improve the situation somebody decided to install 3 fourteen inch wind turbines BELOW the existing ventilation.


    Unfortunately this will not help anything because the wind turbines are placed too low on the north side of the roof and will never spin with the predominately southern trade winds in the spring, summer and fall in Texas.


    Even as passive ventilation they are too low on the roof where heat will exit at the highest point. Too much ventilation this close together will also cause wind washing where each vent will try and pull air from adjacent vents thus rendering them useless.

    Kangaroo Contractors can help you determine the best home attic ventilation system.

    • "Best Money I Ever Spent
      I had Kangaroo Contractors add extra insulation in my attic about a year and a half ago. Since that time, it has paid for itself. Kargaroo Building Services is a professional company, friendly and has competitive prices. I would highly recommend them to anyone."

    • "Very Professional
      Had them do a number of items around the house -- fixing the roof, fixing drywall, retiling the fireplace, replacing some airconditioning ducts,and replacing some faucets. Very professional. Would use them again."

    • Excellent Service
      Kangaroo Contractors installed insulation, radiant barrier foil, an attic tent and a solar fan in my attic this past summer. I have already saved about 30% on my electric bill! They were very professional and completed the work in a timely manner! Thanks Kangaroo!
