Two roofs?

Good catch, Marcel. It looks that way to me too.

Thanks Kenton;

The only concern with the unorthodox framing of James' post would be not knowing how much weight is pin loaded on some of the truss rafters that you see in his second picture.

It might be alright, but we can't see the whole picture.

I guess if James is comfortable with it, fine by me.

Thanks

I see what you man, Marcel. Like where some of those little 8" blocks rest on the truss top chord. In evaluating things like this I try to visualize the failure and imagine what kind of forces could cause it. In this case it would have to be a big snow load in addition to 3 layers of asphalt roofing and maybe some wind ... to me anyway. Hard to imagine it failing without being weakened by decay.
That's mostly a matter of personal curiosity. As a home inspector, if I'm not sure I pass on the liability by saying that.

[quote=bjones1]Looking at the pictures, it appears that the girder trusses may be the wrong pitch, or undersized, hence the build-up. Scenario 2 would have the builder or owner changing the design mid-stream and rebuilding on top of the girders to give a multi-leveled roof design, more esthetically pleasing.


I think I have to agree bjones
something was messed up during the framing and rather than send the trusses back and have the wait time for new ones they just frame over and transfered the load down to the trusses they started with

I've been a carpenter since way back when we still used hammers instead of nail guns and have never seen anything like this. I agree that someone either changed their mind halfway through a job or didn't really know what they were doing and just kept adding lumber whereever they could........how would I report it?

I'm pretty much with Marcel on this one...suspicious of the load on the truss. Framing looks ok. I'd check the plans, see if the monstrosity was originally in there, and make sure the contractor AND the engineer signed off on the changes...if that's what it is.
