Cost of adding ridge vent to roof?

Posted by W. Wells on January 30, 2007, 1:18 pm

I would like to put a ridge vent on my house. I do not need shingles. The
length is about 25 ft.

I realize that it is different prices in diff. parts of the country (US) but
I was trying to get some idea. I am in NC (in a small town) Thks for any
help.

You should ask locally if you need a number you can rely on.

Adding a ridge vent requires intake ventilation lower down, typically
the soffits. Without the complete ventilation circuit the ridge vent
will not work very well. If you're just looking to cool down the
attic, you may want to look at a thermostatically controlled
mechanical vent.

I'd say a guestimate is a few hundred bucks. The vent material isn't
very much and you have the shingles. All that's required is to cut
two runs down the peak, install the ridge vent, and reshingle.

As pointed out above, you do need adequate soffit intakes. Makes sure
they are there and not blocked by insulation. Even if you use a
power vent, and probably more so, you need adequate intake, though if
it's a power vent, you could rely on gable or other vents for cross
flow as opposed to vertical rise.

imho:

I had a guy come and replace mine. Considering the extra step would
be running a circular saw down 25 feet, and back 25 feet. I'm
guessing another hundred or two. So maybe 400?

Just a guess, but then the extra work comes from what is your current
ventulation method? Gable vents, they will need to be
covered/blocked. Then you need good soffet vents too. So this can
add to the overall cost.

Now this is based on past conversations with a roofer, so not a roofer
myself. Get a professional for a quote.

Why do gable vents need to be blocked?
I have no gables on my house and the only attic venting is through several
roof vents (non whirling type). I think probably a ridge vent would be
beneficial but haven't checked into prices. Would my roof vents have to be
blocked? Why?
Thanks
