7 Tips for Securing a Roof Cap Vent to Your Roof 7 Tips for Securing a Roof Cap Vent to Your Roof

A roof cap vent is used to ventilate the attic in a home to better regulate the amount of heat and condensation that builds up on the roof rafters. When there is a lot of condensation on the roof rafters, it can breakdown the rafters and cause them to fail. This means sagging roofs, and even roofs that cave in if not repaired. Securing a roof cap vent is a moderate project that requires a lot of measurement and careful cutting. Here are a few tips to help you with your installation of a roof cap vent.

1 - Use Care when Working with Shingles

One of the first steps to take when securing a roof cap vent to your home is to pry up the shingles that make up the current roof cap. Removing these shingles must be done with great care so you do not damage them and need to replace them. Using a pry bar will help, but make sure that you work slowly and carefully as you remove the shingles. 

2 - Work in Late Morning

Many people like to get an early start on their home projects. However, the shingles of your roof should be pliable in order to make removing them a little easier. Wait until the mid morning hours when the sun has had time to heat up the shingles and make them more pliable for working with. 

3 - Take Careful Measurements

Roof cap vents are located along the ridge cap where just an inch below the ridge line. Measure to a point that is 7/8 of an inch below the ridge line. Make the location along the entire roof with a chalk line. To make sure that this measurement is universal along the entire roof, make several measurements in different sections. You will need to do this for both sides of the roof.

4 - Cut Hole with Circular Saw

There are plenty of saws that can be used in making a hole on a roof. However, the best one to use for a roof cap vent is the skill saw. Set the depth of the blade to the depth of the sheathing of the roof. If you cut too deep, you will cut into the rafters and weaken the structure of the roof. Cut along the chalk line on either side of the roof. 

5 - Remove Sheathing and Nails

After the cuts have been made you can easily pry up the sheathing with a pry bar. It is also important to be able to remove all of the nails that are contained within this area between the two cuts. If any are left they can damage the shingles, or the roof cap vent. 

6 - Install Roof Cap Vent

The vent is installed along the ridge of the home. It is better to use baffled vents so that air does not flow into the attic, but the heated air can be removed. 

7 - Secure Shingles Over Vent

Now that the vent is installed, finishing the project is a matter of reapplying the shingles to the roof. They will lay over the top of the vent, but not obstruct the air flow.
