Installing Roof Vents

This story shows how to install roof vents.

Intro

Ridge and roof vents are easier to install just prior to a roofing job, but they can also be retrofitted onto an existing roof. Soffit vents can be installed anytime.

Venting goes hand in hand with insulation. Measure the thickness of your attic floor insulation (or wall and ceiling insulation, if the attic is finished) and ask your building department or a home center whether you should add more.

If you need more ventilation but don't want to cut a new hole in the roof or gable, consider adding a power vent, which can be controlled by a thermostat and/or a wall switch.

Checklist

Time
Several hours to install most venting products

Tools
Tape measure, drill, reciprocating saw, jigsaw, chalkline, circular saw, hammer and chisel, trowel

Skills
Basic carpentry and roofing

Prep
Determine how much and what type of ventilation you need. Tear off the roofing or plan to cut back shingles for the installations. Make preparations for working safely on the roof.

Materials
Soffit, roof, ridge, or gable vents; nails and screws; roofing; roofing cement

Step 1

To install a roof vent onto existing roofing, drill a locator hole from the inside of the attic to ensure that you will not cut through a joist. Mark the roof with the manufacturer's template and cut the hole with a reciprocating saw.

Step 2

Pry up the shingles surrounding the upper half of the hole and pull out nails as needed. You may need to cut back some shingles. Slide the vent into place so that the top half of its flange is covered with shingles.

Step 3

After nailing the vent in place, cover nails with roofing cement.
