stick roof

[dieselfish]

Hello everyone, Im new. I live in ohio. I'm plannin a 12X22 addition on my house and someone told me stick frame roof would be the best and strongest. I plan on having a vaulted ceiling with skylights.

and advice would be appreciated , thanks in advance

Stick framing a regular ceiling/roof is hard enough. Go to the local supplier and ask about trusses, give them dimensions that are as exact as you can give. You will need to know:

Span (wall to wall)
Overhang
Pitch of roof
Pitch (if any) of the "sides" of the ceiling
Offset between the lower and upper part of the ceiling
Dimensions (both ways) of the "box"...the vaulted part of the ceiling
The on-center spacing (you can tell them...and they'll probably tell you if that's necessary, and if it's close enough)

That's all I can think of...

HMMMMM...anything else Tom?..or anyone else

I dont do framing so I will probably have it done but would like to get the heads up. Does anyone recomend any overhang? venting?

[jproffer]

Overhang 18". Vent the soffit only if you're going to vent the ridge as well, or you're wasting your time and money.

just FYI: I recently bid an addition job and got a quote from my supplier (itemized of course). The lumber for the roof and ceiling framing was more than the cost of trusses, not to mention the labor charges they saved. So if you're hiring this out, I would insist on trusses if there is ANY way possible. If you're not sure ask them to price it with trusses(material+labor) and also with stick(mat.+labor), I think you'll be surprised.

How do you create a vaulted ceiling (cathedral?) with skylights using trusses? Am I missing something here?

Scissor trusses?

Ignore the dots and even still they don't look a great deal like that, but you get the idea....I hope :?

Here's a link to trusses and scroll down to where it says scissir trusses and you'll see.

The problem for me with scissor trusses is that you don't get a nice high vaulted ceiling. If your top truss is an 8/12 then the vaulted part will be maybe a 4 or 5/12 pitch.

I don't use trusses but his roof is easy enough to stick frame with just a structural ridge. He can have the valuted ceilibg as high as he wants.

So the "vault" would be a small portion of the potential roof space? The skylights would then need to be somehow framed into the truss system and deeply recessed at additional cost. It seems like a lot of trouble to achieve something less impressive than a stick built cathederal ceiling. Just my design opinion.

Dieselfish, check out this Cathedral Hip Roof (http://www.jlconline.com/cgi-bin/jlconline.storefront/42f8c29700073ef727177f00000105a7/UserTemplate/82?s=42f8c29700073ef727177f00000105a7&c=7ced7383bf37a4c2d09f91512724e381&p=1) article.
Another way I've seen a vaulted ceiling done is with the hips all meeting at a small central decorative post. The hip rafter peaks were secured to the center post with knife plates both bolted to the post and inserted in a slot in the rafters and through bolted. The rafter feet were similarly joined where they met corner posts.
