Wind Mit - Roof to wall connection

Hey guys, I wasn’t sure about this. Client wants to get clips installed and wanted to know if it would count. I don’t know what this wall extension is called. (Double top plate?) It would be at the red marks. Thanks!

I’m not in Florida, but perhaps this will help…

I’m not in Florida either. And what Jeffrey posted is quite different, as I see it, from your picture.

His is a truss system with gusseted connections from “ceiling joists” to “rafters” with the hurricane tie at the truss/wall joint. Thus continuing the structural integrity of the roof to wall system.

Your picture would need connectors at each joint, from rafter to wall, to connect similarly. IMHO

Larry, can you answer the OP’s question?

I don’t know. I guess I would call it a knee wall or wall extension. :man_shrugging:

Expanding on @jjonas post. I would go with “raised heel”. Raised heels can be framing or trusses. And here is a good video which explains their purpose.

To me that small wall looks like a very small cripple wall built above the top plate -prone to hinging, which does act like a raised heel. Ideally it should have been reinforced with plywood over the joint. The ceiling joists/collar ties may add some resistance to the thrust that is occuring at the lower section.

Exactly. I find it interesting in the OP’s photo, there is NO insulation visible whatsoever! So, was this a design element, or an insulation application flaw, or both?
Also note, that the ceiling joists and roof rafters to not match up. This is unusual in my area. Going “on-site” built allowed to save expenses on materials/cut corners?
The more I look at that one photo, the more questions I have. So for the FL. Wind-Mit experts, how does all this apply to the task at hand??

Likely the garage area where it is easily visible.

Doesn’t matter what it is it still needs a hurricane clip.

That was my assumption, but like Roy stated…

Roy, what is your professional opinion on how this should be handled for the Wind-Mit?

It’s so hard to tell what is going on from that photo. However, as I see that photo I don’t think we are looking at an exterior wall at all. The clips need to be installed where the rafters join the outmost exterior wall to get any credit for a wind mitigation IMO.

I’m with Jeffrey on this, there are just more questions than answers at this point.

Is that actually soffit idk. Sure would be nice to have some exterior photo’s here and get some clarity from the OP to verify that your labels are actually what is going on here.

Yup… sure would be nice if the OP’s on these type of threads would actually participate in solving THEIR issues, instead of pulling the Dine-and-Dash routine. OUR time is just as important as theirs is!

Is this a block frame house is my first question and if so there would need to be some type of continuity from block to wall to rafter as Larry already stated.

I would call it a knee wall requiring clips in multiple locations fallowing the path down,

If that is the weakest point of roof to wall attachment, it would be a toenail.

Looking at what looks like a pt 2x8 that the so called knee wall is sitting on l would guess that it is a block wall. :thinking:
