To fight heat and moisture, which are enemies to your home, you must ventilate year-round. Ventilation supplies a continuous supply of air through the attic space.
Proper ventilation consists of 50% intake, under the eaves, and 50% exhaust near or at the roof peak, at least three feet higher than the intake system. When remodeling or re-roofing your home, ignoring a proper ventilation system could result in damage to shingles, roof sheathing and possibly migrate to your living area causing mold, mildew and paint blisters on the inside of your home.

Additional Vent Types
Foundation vents help remove moisture that can lead to damp rot. Damp rot can cause damage to your home, as well attract termites.
Gable vents are exhaust vents and should be used in conjunction with intake vents. Intake ventilation is an essential component of a properly designed ridge vent system. To maximize ridge vent performance, air intake vent area should be equal to or exceed the net free area installed at the ridge. Mulligan offers a variety of intake vents to fill this need.
Power vents quickly exhaust heat or humidity from any attic. They work on a thermostat, which automatically turns the fan on when cooling is needed.
A ridge vent runs the entire length of the roof peak, blending into the roofline. A ridge vent installed with an internal weather filter, combined with undereave venting is the most efficient system you can install.
Ventilation and air circulation are an integral part of keeping a home comfortable while prolonging the roof's life. Mulligan roof vents also keep out weather and other hazards. Typically, 7-8 roof vents are installed per 1,500 square feet of roof surface. These vents work with gables and hips and can be installed with virtually every commercial and residential roofing material.
A turbine vent system is the most effective and most affordable system you can install. One turbine vent can do the work of 7-8 roof vents and achieve maximum airflow. A turbine ventilator installed with proper open soffit ventilation is the right formula for an effective turbine vent system.
