Prevents Heat Build-Up to Keep Your Attic Cooler in the Summer, and Removes Damaging Moist Air from Your Attic in the Winter.

Ventilation You might think that the most energy-efficient attic is one that is sealed tight against outside air but that's not case. Proper attic ventilation is not only required by building codes, its an integral part of The Energy Efficient Attic® solution.

We employ a combination of soffit vents and ridge vents to pull air through the attic. Wind or natural convection pulls air out of the attic through the ridge vents, while replacement air flows in through the soffits. It's a system that works with no moving parts or energy consumption. Depending upon the structure of your roof, other systems may be recommended - we also install wind turbines, air hawks, and a variety of powered and solar-powered vents.

In warm months, adequate attic ventilation prevents heat build-up in the attic, thereby reducing the load on your cooling system. In colder weather, it serves to pull out the warm, moist air generated by your laundry, showers, cooking, etc. (3-5 gallons per day - or more). If not vented, this moisture can condense on cooler solid surfaces and drip - becoming trapped in roofing and insulation, which can cause extensive damage.

Proper attic ventilation also contributes to the performance of insulation and radiant barrier spray. The results are added comfort in all seasons, reduced energy consumption throughout the year, and the prevention of damage to
your home.

Frequently Asked Questions
Wouldn't the most energy-efficient home be one that is the most airtight?


Controlled ventilation and air leakage are two different matters. Sealing unwanted air leaks is vital to a homes energy efficiency. However, controlled ventilation in your attic is also very necessary.
How does attic ventilation improve energy efficiency?


Ventilation promotes a cooler attic in the summer and a drier attic in the winter. By exhausting heated air from the attic, a good ventilation system will help keep the rest of the house cooler with less energy usage. In cold months, ventilation prevents moisture build-up in the attic. As warm, moist air rises into a cold attic, it can condense under the roof deck, causing the decking and shingles to distort and deteriorate. Excessive heat and excessive moisture can both lead to serious roof damage.
Where does that moisture come from?


It comes from normal household activities, such as showers, laundering and cooking activities that can release as much as three to five gallons of water vapor a day. If this water vapor becomes trapped in the attic, it can cause roof decking and shingles to warp and distort. Lack of appropriate ventilation can void your home warranty.
What kind of ventilation system do you recommend?


The Energy Efficient Attic® solution employs a ridge vent at the peak of the roof plus vented soffits under the eaves. However, depending upon the structure of your roof, other systems may be recommended - we also install wind turbines, air hawks, and a variety of powered and solar-powered vents.
How does a ridge vent system work?


As wind blows around the house, it creates areas of high and low air pressure high pressure under the eaves and low pressure over the peak of the roof. Because air flows from high to low pressure; air in the attic will be pulled out through the ridge vent, to be replaced by air flowing in through the soffit vents. The system also takes advantage of thermal effect to ventilate even on calm days. We all know that hot air rises. The peak vent allows this hot air to continue to go up and out of the house, with cooler air being drawn in through the soffits.
