I am going to have a new roof put on my 15 year old house.



Currently there are several vents on the roof which let heat out. I

also have an attic fan which draws heat out of the attic.



I wanted to know are there any advantages to having a Ridge vent vs

the individual vents placed along the roof?



Also, can you put a ridge vent over an area that has a vaulted

ceiling?



iv owned my own roofing company for 10 years now and as a roofer i would push the ridge vent all day only because i could make more money but as a home owner and my own house i have installed 2 attic fans because they are truly pulling the hot air out over having the hot air gradually come out on it own also attic fans lower your cost of your electric bill because you a/c don't have to run as long and hard to keep you whole house cool and it also keep you shingle from burning up and keep a long life expedience for those reason ill have attic fans over ridge vent in my house but all roofing company including my self will push ridge vent and that's the cold fact



Thanks for any and all responses

Hi,

What if ridge vent or whatever vent is correctly sized?

Whatever the method, they need to be correctly sized.






From the under

eve soffit to vent exhaust opening there should good air flow by

convection. When house is built it should be taken care of. I've seen

many new houses w/o correct static venting. Some times sizing was OK but

poor installation like blocking air channels with insulation batts,

things like that.

It's not unusual to see that, ie the insulation guys shove insulation
all the way into the eaves, blocking the soffits. Should have plastic
baffles there to keep it open.




Vent fan is in a way remedy effort after the fact.

I am firm believer of Doing things first time right. For the long run it

saves time and money.


A vent fan still needs fresh air to come from somewhere, just like a ridge
or any other vent. In fact, one of the main arguments against power fans
is that they can pull cold air from inside the house up into the attic.
The air will go through any openings available, like recessed light fixtures,
around bathroom fan openings, etc.

Anyone interested can do some googling and find that most experts today
recommend ridge vents over power vents.
