Having a proper attic ventilation system is more important than you think. Inefficient attic ventilation systems can harm not only your wealth, but your health as well. Uncirculated air allows heat and humidity to linger in your attic and home. A well balanced attic ventilation system is an efficient approach to energy savings.

If your attic construction requires alternate forms of ventilation, we will evaluate your unique situation and recommend the proper method of ventilating your attic. RSS installs attic ventilation systems in Houston and its surrounding areas.

Attic ventilation is extremely important year round. In the summer, we need to move the hot air (up to 160+ degrees) from the attic and replace it with the 95 degree air from under the eaves. In the winter, we need air movement to remove moisture from attics. We are the experts in Houston Energy Efficiency and Houston Ventilation.

 

 

Conventional wisdom says you need one square foot of attic ventilation for every 150 sq ft of attic floor. This is made up of approximately 60% intake (eave vents) and 40% exhaust (roof vents).

The best way to achieve this depends on your attic design, the options include:

Common forms of eave vents:

• Continuous soffit vents – 9 square inches per foot
• 8x16 soffit vents – 65 sq inches each
• 4x16 soffit vents – 25 sq inches each

Common roof vents are:
   

• Ridgevent – 18 square inches net free per foot
• Wind turbines – up to 1342 cubic feet per minute
• Air Hawks – 61 sq inches each
• Power vents – up to 2000 cfm

 

1. Eave Vents for pulling colder outside air into the attic are available in white, brown or will finish. Individual eave vents should be installed every four feet or less.
2. Drip Edge Vent combines a drip edge with intake vents for homes with little or no soffit. Drip edge vents install behind the gutter.
3. A shingle-over ridge vent which features an external baffle that maximizes airflow performance and protects the attic from weather infiltration. It's low-profile design allows the vent to blend in nicely with the roofline

The external baffle ridge vent creates a lower air pressure above than below, thus creating a gentile suction that removes the hot attic air. The stronger the breeze, the more hot, humid air is removed from your attic.
