Sagging parapet, kickers tugging on roof.

Sagging parapet, kickers tugging on roof.

Sagging parapet, kickers tugging on roof.

Hi folks, I'm new to the forum and I hope I can find a few suggestions to my issue. I have been approached by a client who has a flat roof store where the parapet on one corner of the store is sagging by about foot. I took some pictures of the roof, please see attached. The parapet is about 8' tall and is supported by kickers. You can see the roof deform around the roof joists due to the sagging. Any suggestions on how to fix this? I prefer to not have to redo the waterproofing. The office below has suspended ceiling panels. Questions as follows:
1- What's the least invasive way to fix this?
2- Can the parapet be jacked up and we then install support beams to prop it up?

Thanks in advance, I appreciate any and all advice.

This might be better served in the general discussion. I would try to go into the store below and look up through the ceiling at the joists to get a better idea of what is going on.

Yeah, without seeing the construction detail, there's not much to comment on

RE: Sagging parapet, kickers tugging on roof.

I agree with both - 1) this is clearly not wood construction, so the Structural Engineering General Discussion is more suitable than the Wood Design and Engineering forum; 2) without seeing exactly how that overhang and parapet were framed, it's very difficult to give valuable suggestions.

RE: Sagging parapet, kickers tugging on roof.

Suggest to exam the support structure from below. I suspect there is ponding situation produced by inadequate/incorrect roof slop. Some support members could have already failed with time. Moisture and humidity could have something to do too.

This isn't posted to the correct section. This does not appear to be wood construction.

RE: Sagging parapet, kickers tugging on roof.

I suggest you contact a local structural engineer and have him or her review the framing and suggest a solution.
