Protect Your Investment With Our Roof Ventilation.
A ridge vent is a ventilation strip placed along the home’s ridge line. Before installing the ridge vent, a one-inch wide strip of roof decking is cut out along both sides of the ridge line to allow for air movement through the vent. It is important that air movement occurs and is not impeded by any framing of the home.
Soffit Vents & Insulation Baffles
An essential part of installing any ventilation system into your roof system is ensuring that there is a point of entry and a point of exit for airflow. The soffit vent allows convective air movement from the home’s soffits to the ridge vent. Insulation baffles must be installed at the point where the attic floor meets the roof line to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents.
House & Attic Fans
Fans and vents may be installed on the roof system to draw the air out of the attic space and exhaust it to the exterior. These fans may be controlled with a switch or a thermostat which detects heat build-up in the attic space and automatically exhausts the attic space. We also offer solar-powered options.
Common Types Of Roof Ventilation
Proper attic ventilation systems allow a continual flow of outside air through the attic, which in turn helps protect the efficiency of the insulation and helps lower temperatures in the house’s living areas. It consists of a combination of air intake and air exhaust. Air intake is pulled through your eaves or soffits, and air exhaust is at or near your roof ridge.
How Our Roof Ventilation System Works
Types Of Damage That Can Result From Improper Roof Ventilation
- Premature aging of your roofing system (fried shingles)
- Warping, cracking, rotting or breaking down of wood framing
- Damage to siding, exterior or interior paint and wallpaper
- Mildew growth
- Buckling of shingles and felt
- Ice dam formation
- Increased load on air conditioner
- Contribute to household appliances, bathtubs, showers and cooking vapors building up excess moisture in the attic and reducing insulation efficiency
