Installing ridge vent for a newly constructed home or on a total roof replacement is preferable as opposed to conventional vents because ridge vents cost a little more, but it takes more time to install. However, this kind of vent offers a better air circulation as opposed to turbine or garble vents. Although ridge vent installation is a little bit more complicated, you can do the installation easily using some instructions below.
The first thing you have to do is install the plywood sheering as usual from the lower edge upward, but don’t install it all the way to the ridge because you need to leave a 3-inch gap on both sides where the ridge vent will sit. After that, you can apply rolled roofing underlayment according to the manufacturers’ specifications while leaving 3-inch opening along the ridge again. Install roof shingles on the top of the plywood and trim them to fit with the gap at the top. In all ridge vent installation, the ridge vent will sit on the top of these shingles and it will extend from one end of the ridge to the other. Now, you can place the ridge vent on the top of the shingles using roofing nails to attach it to the plywood beneath. If you have multiple pieces, you need to fit the pieces together. Cut them with band saw and position the ends together. After that, you can apply ridge shingles over the ridge vent to cover the metal of the vent providing a nice finish while allowing both sides to perforate releasing air. Place the first shingle even with the outside of the ridge, make the bottom flush with the gable end and secure it with roofing nails at the top. Place another ridge shingle over the first overlapping the firsthand repeat it all the way to the other end. The last trim any excessive ridge shingles by snipping them carefully.
Those are some steps you can do to complete ridge vent installation and get a better air circulation in your roof.
