How can I install attic vents?

Is your home unbearably hot in the summer? Are your energy costs rising each year? Consider installing an attic vent. This simple solution helps release trapped hot air and excess moisture, preventing them from accumulating in your attic. It also offers a great way to reduce your cooling expenses and extend the life of your roof shingles [source: Preble].

If you're thinking of installing the vent yourself to save on costs, you're in luck—the process is quite easy. Start by determining the vent's placement, cutting a hole, inserting the vent, and securing it in place. There are various types of vents, and some may require additional steps, but these general instructions should guide you. Be sure to consult the manufacturer’s directions for your specific vent model.

For a gable vent, begin by using a circular saw to remove the siding and sheathing in the area you've chosen, taking care to avoid damaging the gable studs. Once you've made space, apply caulk around the hole and place the vent in position. Then, simply secure it with screws and your vent is installed.

Adjust your circular saw to 1/8 inch (0.4 cm) more than the thickness of your roof's soffit when installing an intake vent. Then, cut out the desired area and secure the vent into place with screws. Ensure there is a gap between the insulation and the vent; otherwise, the vent may be blocked and not function properly.

When installing a ridge vent, follow the manufacturer's instructions carefully, as the process may vary. Generally, you’ll remove shingles near the ridge's end, around roof intersections or chimneys. Remove felt paper, nails, and staples, then draw a chalk line along the roof sheathing on both sides of the ridge. Cut the sheathing along the line and place the vent over the peak, securing it in position.

For a roofline or turbine vent, begin by removing any shingles or felt paper between the rafters where you plan to install the vent. Cut a hole to match the size of the vent's throat. Apply plastic roof cement to the vent base, then place the base over the hole. Position the flashing’s top end above the shingles, ensuring it overlaps the area beneath the hole. Use roofing nails to secure the base and seal the nails with roof cement [source: Do It Yourself].

Before beginning your installation, check local and state building codes and take appropriate safety precautions. Don't forget to read the manufacturer's instructions, as they may include more specific details necessary for a successful installation.
