That will be a bouncy wall unless you put joists in it. Are you after more head-room or a higher pitch for shingles/water shedding?

It'll give you about 2-1/2' or so of flat ceiling at the upper end. Put your can or track lights there too if your want. (The collar ties shoud run from all the way inside your 4' wall and the longest point should be right at the roof sheathing.) __________________ Frank To view links or images in signatures your post count must be 10 or greater.

mattt Newbie   Join Date: Jan 2012 Posts: 4	raising shed roof pitch Thanks for the responses! The 4ft collar tie idea would look good and work too-- but the ceiling' had to' match, just decided to tear into the wall instead and run full studs at intervals.. the can of worms is open. Thanks again.........
