Looking for answers
My wife and I purchased a contemporary house almost 2 years ago. It has 2x8 framing for rafters with cathedral ceilings everywhere. The problem is we only have r-19 insulation. I am looking for a way to add as much r value as possible without removing the drywall.
First solution would be: to tear of sheathing and have a company intall spray foam insulation, very expensive.
Second solution: leave the sheathing on and install 2-3 inch foamboard, with new layer of 7/16" osb and roofing material over that.
My question is has anyone ever encountered anything like this, if so what is the best solution?

Wow... no comments????
Well I did do a rrof once that had SIPS panels over the regular sheeting ,but I think it would be pretty expensive.
The main thing that I am worried about is ventilation. Do you think that I will have to vent agian. There is a void between the insulation and the sheathing, with vents in the soffit and on the ridges.
Building science website, Fine Home Building (they ran an article a way back), search on my name for Closed Cell foam - that will give you at least 4 threads on this subject just in here
FYI - everyone in life is looking for answers - if the title was "cathedral ceiling venting / insulation ???" or something similar you would have probably gotten a better response

Sorry dude, but I am not so familiar with the website forum edicate. I was reluctant to even ask a question on here for fear of feeling like an ass, oh well.
You know what everytime that I have ever posted on a forum there has always been some ******* who obviosly has more time that I do to hang out on the internet and be the master of this here universe.
I just figured that I would get some opinions on here, I guess not.
Late.......

Jay - there is simply not enough info in your post & you hit one subject that requires you to do some major research. I was simply pointing you to a good starting point & also trying to help you out on future postings.
If you feel the need to call others names for your lack of knowledge & ability to listen, learn or think - go right ahead... I will just forewarn you - that is frowned on in on most forums and civilized places on this planet

SIPs might be the way to go.
Ok it seems that everyone is agreeing on SIP's. If I am not mistaken isn't a SIP basically a foam core sandwiched between two types of skin, i.e. o.s.b. If that is the case what would be different if I already have o.s.b. after I strip the roof, install foam board, and cover with o.s.b., would that not be a homade SIP? Or is there some other reason why I should not do this?
There is still the ventilation question. Which would have to be addressed, or not, even if I did use SIP's. Do you think venting would be an issue???

How bout adding furring strips say 2" and fill in between with 2 inch foam to the underside of drywall and then hang a new ceiling
Well, I will have to appologize to you for flying off the handle and calling you names, I was in a bad mood.
I will keep your instruction in mind next time I post.
I hope that you will forgive me
Are you saying that because of ventilation? because I need to install a new roof anyways.
No I was just tryin to save u money. Didnt know u needed a new roof. You know r 19 isnt the end of the world. Some people would be lucky tio have that
I hear you, but I have cathedral ceilings that go all the way up to 30ft. A lot of heat gets through it in the winter. I'm sure alot gets through in the summer the opposite way.
What do you do in residential construction?
Uh oh here comes a test. I do everything from additions to decks.
Nah Just sounds like you are over your head and about to **** up a house
Man, I gotta start doing more additions and decks. I dont have no 30 ft high cathedral ceilings in my house
This is my house.
My wife has a good job:w00t:
