Raising ceiling, using rafter ties


Our attached garage will be converted to bedroom/bathroom. The current rafters are 2x6 24" o.c. The ceiling is comprised of 2x4s 24" o.c. I would like to remove the 2x4s and add 2x6 about 4 ft. higher (still within the lower 1/3 of the attic space).

I've already contacted the building inspector, but waiting to hear back. Anyone know if this will work? He didn't say it wouldn't when I mentioned it earlier, but I thought I'd double check.

It should work. Do not remove all the existing until you replace with the new. Not good if the walls collapse out.

Thanks,
I didn't plan on removing anything until EVERYTHING was added. Anything else that might need to be taken care of?

make sure your rafters are attatched to top plate with huricane clips

he is planing on moving the new rafters up 3' so no attachment to the top plate will be possible. But you do need to nail to the rafters so the ceiling joists do not twist.

2x6 rafters span 11’9”, 24”o.c. (horizontal) 2x6 ceiling joists span 10’6”, 24”o.c. 2003 IRC

Measure carefully the 1/3 rule: http://myconco.com/ComEngProb.html

There may be some adjustments on the span: http://www.ct.gov/dps/lib/dps/office...06/i-02-06.pdf

They may require more nails at the rafter tie/rafter connection: http://www.engineersedge.com/civil_e...onnections.htm

And you know about window egress and furnaces….

Be safe, Gary

Do you mean nail the rafter ties to the rafters? I figured on doing just that. I may decide to use 2x8 for rafter ties instead of 2x6's since they will span about 15'.....although I'm only attaching t&g carsiding, so the weight won't be too much.

I would also add metal hurricane clips to support the rafters to the wall top plate since you are now placing more stress on this connection.

Great Stuff. Thanks Gary.

If anything that'll supply with some talking points with my inspector.

BTW...I can't believe how many nails are required for the rafter tie joints...
Do it the right way.

It seems that there is not much work going on in sandy hook,ct if there was, then bob mariani would be busy working other than having too much time giving his advice on every post on this forum. Perhaps bob you could get on the contractors talk web site.

About that 1/3 rule. The rafters span 12' from top plate to ridge. If I measure 4ft up on each side of the rafters, can I attach the rafter ties at the 4' mark or does the entire rafter tie need to be within the first 4 ft. ( the bottom of the rafter tie would be at 4 ft.)

Since garage sits 3 ft lower than the house, as you walk into the space from the house you'd be hitting your head on the ceiling as you enter through the door. I could at best lower the rafter tie 3-4 inches, but again, the entire rafter tie would not be in that 4ft range. Suggestions or comments?
