Hi, I'm Bill Ragan with Bill Ragan Roofing Company.
I've been in the construction industry for over 40 years
and I've owned Bill Ragan Roofing Company for over 30 years.
At Bill Ragan Roofing Company,
we want our customers to be well-informed
so they can make the best decision when they buy a roof.
Today, we're gonna be talking
about roof ventilation systems.
We're gonna be talking
about what a roof ventilation system is,
the different types of roof ventilation
and also what roof ventilation costs.
What is a roof ventilation system?
A roof ventilation system consists
of two different types
of ventilation.
You have your intake and you have your exhaust.
Your intake is where the air comes in down at the eaves,
either through the soffit
or through a vent placed just above the gutter,
a place for air to actually come in.
Then you have exhaust,
which is the vents that are placed up at the ridge
that lets the air out.
A ridge ventilation system
is an extremely crucial component
to the life of your actual roof system.
As a matter of fact,
an improperly ventilated roof is about the only thing
that will void a manufacturer's warranty
on your roof system.
It is also the life of your HVAC system.
A poorly-vented attic
could make your air conditioning system
run much longer in the evening than it would
if the attic was properly ventilated.
The roof vent system is a truly crucial component
in the actual roof system itself.
What are some of the types of vents?
There's two different types of exhaust vents.
There's active exhaust vents and there's passive vents.
A good example of a
active vent would be a power vent,
whether it's a solar-powered power vent
or even electric motor power vent.
A good example of a passive vent
is just your standard box vents
that you see on a lot of the newer houses
or even a ridge vent that doesn't have a baffle.
Passive just means it just lets the air out.
It doesn't have any drawing effect to it whatsoever.
What are the costs of roof vents?
Roof vents are gonna vary in their costs
depending on the quality of the vent
that you're buying and also how many you're gonna need.
So depending on the size of your attic.
For a good ridge vent, you can expect to pay anywhere
from six to $8 a linear foot.
Turbine vents, installed,
you can expect to pay somewhere around $300 a vent.
A power vent could cost you up to $500
plus what it would take to get an electrician
out there to hook it up.
A good solar vent could cost you in the $800 range.
So depending on what type of vent you're wanting
and how many you need is gonna have a large effect
on how much you're attic vent's gonna cost.
