Help with Roof

All,

 

I am working on a house that the customer wants a vaulted gable roof over the great room. I would like to get this gable roof to span the entire great room if I could, but can't seem to get the roof lines to work. I also don't want a very tall gable wall at the great room. See the below images to what I am talking about. I also attached the plan file for reference.

Any suggestions or help will be appreciated.

 

Thank you in advance,

 

Chris

What's the problem?

 

The problems is I can't figure out how to get the gable roof to go farther back in the Great Room, so all of the great room has the same vaulted ceiling. It looks like I almost need the ridge elevation of the main roof and great room roof to match. Just looking for another set of eyes basically.

Have you tried a lower pitched framed ceiling over the great room but under the main roof? Will take some testing to see what pitch would work. Also might require a structural ridge on the high main roof over the great room area to carry the load of the main roof rafters. A 2-story great room ceiling with a reverse gable coming out the back and over the rear porch might work also.

No I haven't. I always use structural ridges, hence why I think the roof over the great room needs to go back to the front wall of the great room, so I can post it down or connect it to the main ridge. The client wants to have the gable as shown, because they want windows up in the gable end.
