I recently came across an old type of roof structure while fighting a building fire in Seattle. I have not seen it before, and quite a few of us don’t know what to call it? I was wondering if anyone has heard of it before and knows what it is called. It was a flat roof that had 2x4s on edge, sandwitched side-by-side completely covering the roof area. This had a torch-down applied over the top. 2xs all laid on top of flat truss assemblies. I’m not sure what to call the layer of 2x4s all packed tight on edge. Thanks,
Brady

It's just a really big parallalam laid on its side! My FIL grew up in Pasa Robles, CA, and there still is there a 12' square silo made from flat stacked and nailed redwood 2x6s,; must be 40 feet high.
I think it's from a time when wood was cheap, though I have seen an interior mezzanine made that way in a house in a magazine.

It's a "Hide those stolen two by fours quick guys, I donm't care what you do with them, just get them out of sight" roof.

Wonder what a 2x4 rafter will span 1 1/2" o.c.? Can't seem to find that one on a span chart. :)
it's to resist those fierce seattle rain loads,snow loads,wind loads,meteorite loads,falling piano loads,godzilla foot loads . . .
Thanks everyone for the input. Yes, obviously it's a rather screwed up roof! I guess there's no name for it other than that!

it known as the "Way too much forking effort to build" Roof.
Probably an engineers place...I have no comment...
Kinda sounds like an old industrial floor. Was there maybe once an additional floor on top, or might the building have been designed to add onto vertically?
