Installing Attic Vent: A Step-by-Step Guide

Installing attic vents is more than just a good idea it's absolutely essential. Ventilation is key to keeping your attic cool and preventing excessive moisture buildup, both of which are crucial to preserving the integrity of your roof. So, how exactly do you go about installing attic vent? Let's take a look.

Gathering Materials

You will need a few basic tools and materials for this project. These include a power drill, screws, a level, a saw, caulk gun and sealant, a jigsaw, insulation strips or foam boards, an exhaust fan (if needed), plywood sheets (for the frame of the vent), and finally some wood or metal braces. You should also have protective gear such as gloves, safety glasses, a dust mask (or respirator), hearing protection and work boots. 

Choose Your Vent Type

The two most common types of attic vents are ridge vents and gable vents. Ridge vents are installed along the peak of the roof and allow air to flow in from either end. Gable vents, on the other hand, are installed near the eaves and allow air to escape from the attic. Both types of ventilation have their advantages and disadvantages; for example, ridge vents are more effective at providing continuous airflow but require significantly more installation time and effort than gable vents. Ultimately, it's up to you to decide which type best meets your needs.

Measure for Success

Once you've chosen your vent type, it's time to measure for success! For ridge vents, measure along the peak of your roof from one side to the other (this is called "ridge run"). For gable vents, measure across the width of your wall opening at its widest point (this is called "wall opening width"). Make sure you double-check these measurements before purchasing a vent!

Install Your Vent

Now that you’ve got your measurements down pat, all that’s left is actually installing vents in attic. If you’re going with a ridge vent, start by cutting out a hole along the peak of your roof using a saw or reciprocating saw. Then affix the vent into place using screws or nails (whichever works best for you). If you’re going with a gable vent instead, use a jigsaw or circular saw to cut an opening in your wall large enough for the vent itself then secure it into place with bolts or screws as needed.
