How to Install Strip Vented Soffits How to Install Strip Vented Soffits
Strip vented soffits provide natural venting to keep the attic space cooler during a hot day. This ventilation solution allows the heat to escape through the openings and thus permit air to freely move in and out of the room. It helps reduce heat damage to the attic because it prevents heat from building up. Installation procedures for this type of vent vary from roof to roof, but follow the same installation principles.
Step 1 – Measure the Soffit
Measure the dimensions of the soffit to determine the needed strip vents. Use a chalk box to mark the location of the vents. Snap the chalk liner 2 inches away from the soffit edge and snap another line parallel to the first one 2 to 4 inches apart. The distance between the snapped lines will depend on the width of the strip vent to be installed.
Step 2 – Cut the Opening
Before proceeding, wear safety goggles and protective gloves. Use a circular saw to cut the length of the opening. Position the blade directly on each marked line and allow the saw to cut through the soffit. Do not set the blade too deep so as not to accidentally cut anything on the attic. Use a chisel and a hammer to cut the ends of the marked lines to complete the opening. You can also use a saber saw instead of the chisel and hammer method to cut the ends.
Step 3 – Install the Strip Vent
Position the strip vent into the opening on the soffit and fit it firmly. Secure it using ½-inch screws provided in the kit. With a drilling tool, create the screw holes about 12 to16 inches apart from each other. Insert the screws and tighten them properly using a screw driver.
On the attic floor, remove any insulation near the vent track. Use a piece of wood or a garden rake to pull away any loose insulation material gathered near the track. Never allow any insulation material near the vent as this may block the airflow and cause heat to build up. To ensure that the insulation material is kept away from the track, cut 1x4 wood pieces and attach them near the edges of the vent.
Step 4 – Install Rafters and Ridge Vents
Natural ventilation also requires the installation of ridge vents on the roof ridge. However, it is important to provide a path for the airflow to go directly up the ridge. Install the rafters to the underside of the roof following the manufacturer’s directions. Afterwards, install the ridge vent to the ridge as well.
As long as the strip vented soffits, the rafters and the ridge vents are installed correctly, the air will flow naturally inside the attic and thus provide cooler air for the home during the hot season.
