Walls and Ceilings - cathedral ceiling

I hope I placed this in the right section...I have an enclosed porch which I have just gutted the inside. The ceiling was tongue & groove which i removed. I would like to keep the cathedral ceiling. The roof raffters are 2x6. My question is ...I want to insulate & drywall this ceiling. Would I have to put some type of breather in between the roof and the insulation. Any help would be appreciated.

Thanks

Anthony

If the room has a ridge vent up top and soffit vents on the edges, then yes, you can purchase rafter vents that sit in the rafter bay first before the inulation. They are at any home center store. they are super lightweight and are pink. usually about 14"x36" each. you can cut them also. they allow the room to breath.

Bob, No, I don'rt see any any ridge vent or soffit vents. How else can I insulate and allow it to breathe...if that is an issue.

Thanks'

If your gutting it anyways, just go up and rip up the ridge cap on the roof, cut out the center appro 1-1.5" on both sides of the peak-you only need to go within 12" of your soffit on the gable end. Install the ridgevent and new ridge caps and your half way there, maybe 2 hrs total and $50-75 in material depending on how long the run.

If you dont have soffit vents you have to have them regardless of roof venting system used, you need to evacuate the hot/old air. since the ceiling is gutted, you should be able to climb a ladder from the inside and look down into the soffit area to see what kind/if any soffit vetns are in place, and then take appropriate actions.

Your existing soffit will determine what type of vents to use for ease of isntall and performance. Full soffit vents in this situation would be the minimum I'd use. Staple the polystyrene shoots to the underside of the roof sheeting and have them extend into the soffit area just past the top plate and run them all the way to the peak to allow the hot air to escape and prevent condinsation build up.

Side note, a buddies dad thought "he knew best" with his addition and catherdral ceiling and just installed batt as thick as his rafters and had them rest against the roof sheeting....went back this spring while they tore out the ceiling drywall due to ice forming internally and ruining the ceiling LOL!!! I love know it alls!!!

IHI,

Thanks for the response...You really layed it out to the letter. I will do that since it needs new shingles also, so cutting the peak will be easy. For some reason their were no soffits installed so I wll have to do something about that...Thanks for the input

If your eaves dont have any soffits I have to assume they used gable vents to allow air transfer? if there was no way for any air to get in there, it's no wonder you have to replace the shingles, they're gonna be all brittle and flakey when you go to tear off-dont slide down with the pile:)

If your going to reroof and would like to add some soffit (dont know the asthetics of your house) but you could cut the plywood deck from the current eave 2-3' up, sister up some boards so they extend pst the top plate 12" or so (depends on how well you want it to blend into your existing) then lay the new plywood over the sistered/lengthen rafter tails and tie in into the existing rafters. Then finish off accordingly.

yes, that definitely sounds like the way to go..Looks like I have my work cutout for...But I want it to be correct,,,
thanks

Again

You'll be doing the right thing, just think about it as an investment standpoint. My favorite saying, -the only man that can afford to be cheap is a rich one, he can afford to do it twice.

Many people half azz things to save some money and time... EVERYTIME, it's just a matter of how much sooner or later, it comes back around. The dumb ones never realize this, why the rest of us wonder how they could'nt LOL!!
