The reason your vaulted ceiling hasn't come down is it has a ridge beam that is holding the rafters up and keeping your walls from spreading. You can be assured if you take your ceiling joist out without a ridge beam your walls will spread and your roof will sag or come completely down.

So then it is ok to do the vaulted ceiling since the ridge beam is holding everything up

the problem is is it a structural ridge beam.

This is why you need an engeneer to determine if what you want to do is fee sable.

I'm jumping into this just to reply to this question ..... the reason probably is (can't say for sure because I have not been to your home) that the amount (width) of vaulted ceiling does not exceed the load bearing capacity of your existing ridge. Basically the wider the width of the vaulted ceiling the more load the ridge must carry. You reach a point where what you want (more vaulted ceiling area) and what you have (non-structural ridge) do not work together, that's when you'll have issues.

Hire a local professional engineer that works on residential structures and you'll get it right the first time. Cheap money in the long run.

Sorry for any intrusion ....

Good luck!

Thanks for the info. Could I build a new ridge just underneath my existing one of a 2 by 8 or 2 by 10 n add new rafters from ridge all way down to my wall n then add drywall to that. This way in would not b putting dry wall directly on roof rafters n I'd still have vaulted look n have more depth for insulation n air flow

could it be done ....... yes

would what you propose work ......... don't know

it takes someone at your home viewing the existing conditions and what you want to do to determine that. since you do not know me or my level of knowledge or experience, if I said "yes" would you anyway??????????

You can "try" lots of things, hiring an engineer will get it done correctly the first time. no wasted money, no wasted time and labor. That's my best recommendation for you.

Good luck!

most likely the wall you want to take out is holding some of the vaulted ceiling weight and the weight of the flat ceiling too.

therein lies the problem. you will need a structural ridge beam spec'd from a qualified structural eng... proper load points, the works.
