How do you install rafter vents?
To install the rafter vents, staple them directly to the roof decking. Rafter vents come in 4-foot lengths and 14-1/2 and 22-1/2 inch widths for different rafter spacings. Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor.
How many rafter vents are needed?
The first step in determining how many rafter vents your home needs is to determine your home’s vent space in square feet. The general rule is that you must have one square foot of vent space for every 150 square feet of attic area.
Do rafter vents need to go all the way up?
Rafter vents channel air from the vents in your soffit—that’s the underside edge of the roof—all the way up to the ridge vents at the roof peak. Use a step ladder to install the vents, starting from the edge of the roof and working up to the ridge.
Do you need baffles between every rafter?
Keep in mind not all rafter need baffles, just those with intake vents at the soffit. If you don’t have baffles installed, check your intake vents for any type of blockage for insulation or debris. This can be cumbersome since you will need to squeeze to the corners of your attic.
