hi, this is my first posting to a bulletin board so here goes. my question has to do with the height at the center of a cathedral ceiling. I'm having a small weekend cabin built and the contractor is going to use a 6/12 pitch on a 20' x 24' cabin. I'm concerned that the center height is going to be too high to give a cozy cabin feel. I'm not looking for a really dramatic effect but I don't want a flat ceiling either. I also don't want to heat a lot of wasted space. Given the above dimentions can you tell me the center height with a 5/12 and 4/12 roof respectively? I inttend to have a metal roof installed. thanks for any help you can provide. Also I'm restricted to a 15' height limitation and was wondering if there is anyway I can incorporate a loft of some sort in this space. Once again, thanks in advance for any help you can provide.

congratulations on your first forum posting.
The pitch builders refer to in building a roof is a measurment of inches comparing the rise over the run. So a 6/12 pitch gives you a rise of six inches in height for every twelve inches in run horizontally. Thus for your cabin, presuming that he runs the ridge beam the 24' length, half the roof span is ten feet so in that ten feet the rise above the wall plate height is sixty inches, or five feet, not enough for a loft.
A 5/12 pitch yeilds a rise of fifty inches or four foot two inches in ten feet.
you mention a limitation of fifteen feet in height. That seems quite low to me. if that is measured from the ground and you have irregularity, I would be assuming 18" to bottom of floor joists, 10" for the floor, 10" for the roof thickness, and eight feet for wall height. That gives 11'2" leaving 3'10" for the rise in the roof. That is only about a 4/12 pitch. To do a 6/12 pitch, your cabin floor would need to be right down on the gound. Is this a slab on grade structure?
