Once the decking and roofing are installed a truss roof looks just like a stick framed roof.
What does a roof ridge vent look like.
Start by inserting an end plug into the first section of the ridge vent.
Expect the installation of a ridge vent to run about 500 on average if you.
Vents evenly spaced underneath the roof provide intake.
Use two inch roofing nails to pre fasten the first section through pre drilled holes.
A traditional gabled roof on a home is made up of two sloped sides that meet in the middle.
Let s take a look at some key advantages.
Since each truss is a complete frame trusses do not use a common ridge board and the purlins along with the roof decking provide lateral support.
The design of a roof ridge vent works with the look of your home.
The soffit vents act like the air intake for the home.
Since exhaust and intake must be equal 450 square inches of total intake is required as well.
They allow the house to breathe correctly.
Use the alignment guides to center the vent and for the best look align the end of the vent with the end of the house.
To calculate an example of exhaust and intake use 25 feet of roof ridge vent.
Trusses are set onto the walls of a house and are tied together with horizontal boards called purlins.

Now the ridge vents are sitting perhaps 3 or 4 inches above the base of the chimney on either side and it looks like they were stuck on as an afterthought being a bare metal housing the sits on top of the peak rising above it on both sides of the chimney.
Openings along the sides allow air out of the attic cooling the space and lowering your air conditioning bill.
But for a simple gable styled roof structure here is what a ridge vent looks like from inside the attic of a home.
The point where these two sides meet forms the apex of the roof and is known as the ridge or ridge line a ridge cap fits over the joint between these two edges to keep rain and snow out of the home.
Venting prolongs the life of the roof.
Ridge vents since they are built to be as flat as possible also blend in well with most roofs.
That means roof ridge vents are like the exhaust system.
A ridge cap is a building material that is installed along the ridge line of a sloped roof.
Then you might need the soffit vents too.
In fact since they look somewhat like a flattened book along the ridge of your roof they tend to be nearly invisible from the ground.
Multiply it by 18 square inches the net free air per foot of ridge.
This gives you 450 square inches of total exhaust.
