Installing roof vents on an existing roof is not difficult, but it does require some basic tools and knowledge. The first step is to identify where the vents will be installed. The most common locations are at the gable ends or along the ridge line. Once the locations are determined, the next step is to mark the center of each vent location.

Next, using a drill, create a pilot hole at each marked location. The size of the pilot hole will depend on the size of the vent being installed. Once the pilot holes are drilled, the next step is to install the flashing. The flashing is what will create a water-tight seal around the vent.

Now it’s time to install the actual vent. Start by placing the vent base over the pilot hole and then secure it in place with nails or screws. Once the base is secure, attach the vent cover. Make sure the cover is positioned so that it will allow the proper amount of airflow.
