The best roof vent systems are those specifically designed for the size and build of each specific property. No two roofs are exactly the same so no ventilation should be the same either. Proper roof ventilation systems will save you a fortune by fighting the biggest nemeses to all homes: moisture, extreme heat, and pressure.
Evidence of ventilation problems can be seen in a variety of forms such as buckling shingles, ice dams, blistering and peeling exterior paint near the attic area, and even some ceiling water stains. Condensation builds up when the warm, moist air created in the house below meets with the cooler air in the attic. As you can imagine, this excessive moisture in combination with the heat from your roof leads to problems including mold and wood rot. Increasing attic airflow will alleviate the negative effects of poor ventilation.

Ridge vents cover a two to three-inch opening that runs along the crest of the roof to improve ventilation and reduce dead air in the attic. They work best when installed in conjunction with soffit vents, which should be placed in the lower quadrants of the roof. This allows cool air to draw in through the soffit vents while pushing out the hot, humid air out of the ridge vent at the roof line. We know the improper installation of ridge vents is costly mistakes, so trust your home with the experts at All Seasons Roofing & Restoration.
The soffit vents are placed in the lower quadrants of the roof. They bring in cool air at the base of the attic and through the process of convection, use the heat of the sun as an accelerator to create a fresh airflow that cools the underside of the roof deck. In conjunction with ridge vents or box vents, this simple yet effective process alleviates high temperatures that can deteriorate shingles and create moisture.
Box vents are cost-efficient, stationary, and do not have to be located near the roof ridge in order to be effective. They should be installed in combination with soffit vents to work best. These low-profile vents cover a hole cut in the roof and use outside winds along with the convection process to remove hot air and moisture from the attic. The common practice of using numerous box vents produces maximum ventilation results. The number of box vents needed depends on the square footage of your roof.
Gable end vents are located on either side of a gable roof to encourage airflow. This ventilation system allows a cross breeze through the attic by pushing out hot air with the cooler outdoor air. Gable vents stand apart from other ventilation systems because they stand out as a unique architectural element. Decorative gable vents come in many sizes and shapes, which allow you to add your own unique touch to your home.
