Hello,
My house has not attic ventilation other that the 2 gable vents.

I know I need to add eave vents but would like ya'lls opinion on ridge vents
versus wind turbines.

I have heard the pros and con from friends and family about ridge vents and
wind turbines.
ie, if it is storming badly, ridge vents can let water in.
wind turbines don't last, noisy, etc .....
etc ....

I live in Arlington, Texas. If this make a difference.

TIA.

ridge vents require no maintence, make no noise, i have never had
water get in,

my only problem was a family of dedicated birds who having nested in
the attic previously ripped at the ridge vent to get in. i solved that
the following year by removing the vent and adding hardware cloth over
the openings, put ridge vent back. birds were highly frustrated. i put
uup a couple bird houses as compensation

theres no reason you cant have ridge vent, and add a couple power
vents for severe weather

I've never had water to come in via ridge vents even in the worst of storms.

My ridge vent doesn't leak here in NY, and we get some pretty big
rainfalls, not to mention snowfalls measured in double digits.

Never heard of a ridge vent letting water in. I guess if the nails popped
it could happen. Then again, I don't hear much.

Last ridge vent I took off when replacing a roof was the 10 ft metal high
profile type. PITA getting some of those nail's out. Twist nails. Now I
see a lot of rapid ridge going on. Just put on with long roofing nails.
Not sure how that holds up over the test of time.

I actually have both (as well as gable vents), also in TX. Turbines
have been on my house at least since I've been in it (about 20 years).
I put in the ridge vents a few years ago. Like the other posters, I
see no evidence of water coming in the latter. No evidence for
dampness in attic, etc.

With three turbines up there in these 20 years, I think I've had to
replace one. It just got stuck. The bearing failed. No noise out of
any of them. I'm under a lot of oak trees, so they stay mostly in the
shade, but they get bonked now and then by a falling branch. Noise has
never been an issue in any of mine or, as far as I've been able to
hear, for the fiftyish wind turbines on my block.

I'm in Houston.

No question, do both.

Ridge vents don't move as much air as turbines, but they'll move a bit when
there's no wind to drive a turbine.

We had a hail storm come though the neighborhood recently (about a year or two ago). Probably 75% of the roofs got replaced and most all of them had ridge vents added. I've not heard of any water problems and they sure look a lot better than the turbines.

You say you need more venting, you only"need" more venting if mold is
growing in the attic. Gable vents move alot of air, a few static vent
near the top will be cheapest and release alot of heat.

Turbines are a feel-good thing like hanging strings on vent openings
so you can see if air movement is occurring. They move slightly less
air than an equivalent size open hole in the roof (think Laws of
Physics). Some folks like the industrial look, so if that's your
preference, go for it. Soffit vents and ridge vents are the modern way
to evacuate hot air, and you can't have one without the other.
Manufacturers of the products have guide lines for soffit openings
required for ridge vent effectiveness. HTH

Sorry, but I gotta dispute your assertion there (that turbines move
"slightly less air than an equivalent size open hole in the roof").
Where do you get that? Just from personal experience (having had a roof
turbine in my last place) I can say that they move quite a bit *more*
air than a hole in the roof (but, of course, only when the wind is blowing).

WRONG, venting isnt just to prevent mold its primarily to decrease
attic temperatures which add AC costs, and decrease roof life

Fiddle.

Roof turbines combine two mechanical devices into one:

1. A windmill that turns wind energy into mechanical energy and
2. an exhaust fan that sucks out hot air.

At a wind speed of 5mph, an ordinary turbine moves about 350 cu.ft. of air
per minute.

Assuming 1500 sq ft house, and an attic that's 6' high, 1500 x 6 x 0.5 =
4,500 cu.ft. / 350 = a full exchange of air every 12 minutes. Two turbines
would exchange the air in six minutes.

Whichever you use (and I urge both) make sure you have sufficient soffit
vents. Insufficient intake vents yields two disadvantages: (1) No cooler air
gets into the attic, or (2) the "cooler" air is sucked out of the living
area through leaks around light fixtures, plumbing, staircase, etc.

There are calculations for the requisite soffit openings on the web. Find
yours. Double it. You can't have too much soffit venting.

I think ridge vents were invented in Texas. Ridge vents move more air
than turbines, provided they have side fins, like the one at the upper
right on this page:

http://www.airvent.com/homeowner/pro...dgeVents.shtml

Notice the diagram shows air being pulled out from the attic,
regardless of the wind direction. The side fins also keep out rain.
You'll want any gable vents blocked off, to prevent short-circuiting
of the air flow, and soffit vents installed (soffit vents are highly
desirable regardless of the type of ventilation used).

Have you considered a cupola?

Cupola - An outlet for the natural flow of warm air in an upward
direction is provided through the louvered sides of this cupola, while
adding charm to the appearance of your steel building. Available in 2, 3,
and 4 foot square models, our fully functional cupolas are constructed of
29 gauge steel and are available in a wide variety of colors to match your
building. The cupola comes with a bird screen and color coordinated
flashings, and is available with either light transmitting panels
(Plexiglas) or vents.

We offer a complete line of weathervanes to give your cupola that
finishing touch. The weathervanes come in two sizes - 30” for two and
three foot cupolas, 40” for the four foot cupola. They are constructed
of high cast aluminum, painted in black, and are available in six
different designs; horse (shown above), tractor, horse and buggy, rooster,
cow, or eagle.

Michael,

My house has no attic ventilation other that the 2 gable vents.
I know I need to add eave vents but would like ya'lls opinion on ridge
vents versus wind turbines.

I installed continuous ridge vents and continuous soffit vents on our
house. No moving parts to break or make noise, and no ugly vents or
turbines sticking up on the roof. On a sunny day, you can look at the ridge
of our house and see the hot air escaping from the ridge (shimmery look in
the air from the rising heat).

To work effectively, you must have an intake at the low part of the roof
for fresh air to come in (the eave/soffit vents), and the exhaust vent at
the top of the roof (ridge vent) for hot air to escape. Hot air rises, so
once the roof heats up, the air will flow naturally from intake to exhaust.

Also, the airflow must not be blocked by insulation in the attic. There
should be an inch or more of free space between the insulation and the
underside of the roof. In a traditional attic, the most likely area of
blockage is near the eaves over the walls. You can install baffles in each
rafter bay at that area to ensure the insulation doesn't block the air
flow.

I used the Owen's Corning ridge vents that you apply shingles over. We
haven't had any problems with them in the last 5-7 years.

I am in FL. Last year I got a new roof. I previously had a tile roof
with gable vents at each end of the house. The new roof is
shingle...made by GAF - and it included a Cobra ridge vent. They
covered the vents at each end of the house - the small print on the
GAF literature recommends it. (I was glad to have it done because
some of my neighbors have had problems with citrus rats getting in the
attic and those vents were the only way in that we could see). I've
just compared my electric bill with my last year's bill - and we used
fewer kilowatts. So it hasn't made the attic that much hotter ... as
far as I know mold/mildew hasn't started growing. You'll hear about
it if it does.
