Raising the ceiling


I have a 20 by 40 foot building that I want to raise the ceiling on. The building is on a concrete foundation and inside with the trusses the ceiling is only 6'5". I was thinking if I cut the the rafters and moved them up on the truss itself this would be the cheapest way to raise the ceiling. Is this idea sound or am I making the roof weak?

Raising the ceiling


truss system or rafters would be dealt with differently.
do you have rafters or trusses?
cutting trusses is not a good idea.

Raising the ceiling


By truss I mean the piece that runs straight across from wall to wall. By rafters I mean the piece that runs from roof peak to the wall

Raising the ceiling


I want to cut the cross piece (run straight from wall to wall) and move the piece up about 17" and reattach to the piece that runs from roof peak to the wall

Raising the ceiling


The flat piece that runs from wall to wall is a ceiling joist. It acts to stop the roof from forcing the walls to be pushed outward.

Moving them from the top of the wall to a position 17 inches up will reduce their effectiveness, but it is physically possible to move them upwards.

Having said that, you would need to likely have an inspection done for your location by a qualified engineer or building inspector to confirm that it would be acceptable by them in your region.
Lots of time (around here) where the inspections are only done 'in town', lots of things get done out of town, but the long term results are that "stuff happens" that are not planned for. In your case, I would expect that there would be consequences. The walls might start to lean or separate from the roof, causing some grief. Just saying...

Raising the ceiling


I was afraid that something like that might happen. I understand that the joists are there to tie the walls laterally to the roof. So any ideas on the best way to raise the ceiling? I can try to post some pics in the next day or two.

I guess I would have to raise the whole roof.

By the way. Thanks for all the advice and help. It really helps me having a place to discuss ideas before things start to come apart. You know the old quote ( It sounded like a good idea at the time)

Ayuh,... I'd set up some jacks,+ blocking inside, under the ceiling joists, right next to the walls,...
Then disconnect the building's anchors from the slab,...
Jack it up as high as you'd like, then throw up a tier or 2 of blocks, a knee wall, or whatever to extend the walls downward to the slab...

Post a picture of the rafters/joists/truss
There is a huge difference between stick (joist & rafter) built & truss system
You can't just cut a truss system apart
