When it comes to the ventilation of your roof, you have a few options. Most common here is Florida are roof vents or soffit vents. The purpose for these options is to provide constant air flow through the attic space in your home. Properly designed air flow helps remove overheated air and moisture from the attic and roof system, which in turn prevents extreme temperature changes and moisture conditions occurring inside and outside of the home. Well-designed ventilation in your roof system is essential for proper heating and cooling.
Ridge vents were typically placed at the “ridge” of the roof, which is the highest point. Now, most builders in our area have adjusted to placing ridge vent about 2’ down off the ridge, as shown in the picture below.
These vents are designed to increase the airflow created by holes that penetrate the roof. The openings are then covered with a baffle to help deflect wind and rain. Ridge vents create a penetration into the roof and if are not installed properly homeowners can experience moisture issues, bowing of the vent and erosion of underlayment. Any time you are penetration the roof of the home you leave your roof open to the potential for leaks and moisture buildup.
