What Does A Roof Ridge Vent Look Like

That means roof ridge vents are like the exhaust system.

What does a roof ridge vent look like.

They allow the house to breathe correctly. Let s take a look at some key advantages. The design of a roof ridge vent works with the look of your home. Roofers use a circular saw to cut a long slot along the roof ridge if there isn t one then cover it with a plastic flap as shown or a flexible vinyl matrix.

But for a simple gable styled roof structure here is what a ridge vent looks like from inside the attic of a home. To calculate an example of exhaust and intake use 25 feet of roof ridge vent. Once the decking and roofing are installed a truss roof looks just like a stick framed roof. A ridge cap is a building material that is installed along the ridge line of a sloped roof.

Since exhaust and intake must be equal 450 square inches of total intake is required as well. Expect the installation of a ridge vent to run about 500 on average if you. The ridge vent cut at the roof ridge or peak extends the entire length of the ridge stopping just a foot or so from either end and should give 1 5 to 2 5 of open space no plywood on either side of the ridge board for. Vents evenly spaced underneath the roof provide intake.

Multiply it by 18 square inches the net free air per foot of ridge. 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. Venting prolongs the life of the roof. Start by inserting an end plug into the first section of the ridge vent.

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. Then you might need the soffit vents too. A traditional gabled roof on a home is made up of two sloped sides that meet in the middle. This gives you 450 square inches of total exhaust.

Ridge vents since they are built to be as flat as possible also blend in well with most roofs. 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. Trusses are set onto the walls of a house and are tied together with horizontal boards called purlins. Use two inch roofing nails to pre fasten the first section through pre drilled holes.

Openings along the sides allow air out of the attic cooling the space and lowering your air conditioning bill. Finally you are ready to install the ridge vents. The soffit vents act like the air intake for the home.
