Residential Roof Ventilation
Ventilation - Important Air-flow System
Proper ventilation is essential for the temperature control of your home and to the long-term health of your roof. Ventilation ensures that your attic "breathes" throughout the year, bringing in fresh air through the in-take vents located in the house's soffits, and exhaling stale, humid, hot air through "out-take" exhaust vents. Ventilation circulates the attic air and keeps the attic air dry, alleviating excess moisture build-up, formation of mold, Carbon Monoxide and pollutants.
Select the ventilation that's right for your home
The selection of exhaust vents for your home is both an efficiency decision and aesthetic one.
Ridge-line Ventilation is located at or near the ridge-line of the roof and passively draws air out over a greater area of the attic than wind turbines or solar-powered attic fans. Ridge-line ventilation is covered by the ridge shingle and blends with the roof. Ridge ventilation's appearance is aesthetically more attractive.
Turbine Ventilation uses wind-driven vanes to draw stale air out of the attic. In locations with prevalent wind, these exhaust turbines will actively draw greater amounts of air out of the attic than the passive-style ridge-line vent. In locations with minimum wind, ridge-line or attic fans may be preferable.
Attic Fan Ventilation uses exhaust fans to circulate attic air and remove hot, stale air. Two type of attic fans are available, traditional electric fans that are connected to the home's electrical system and solar powered fans.
We recommend solar fans such as Attic-Breeze as they are self-regulating, increasing or decreasing the fans speed based on the attic temperature and are economical to run. Being solar powered, there are no utility expenses associated with their operation.
Gable Ventilation is only possible when a home has been constructed where an additional pitch exists above the roof-line of the home. In these cases it is possible to install ventilation in the gable at both ends of the home. Preferably, gable vents align with the prevailing winds to naturally exhaust the warm attic air. These vents may also preform both air in-take and exhaust functions. Depending on the situation, gable vent fans can be installed to facilitate air circulation.
