Re: The Wall Of SHAME!


I've run 10' spans on low slope roofs with 2X4s. Accessory structures only. Solid.

There's a little twist to the framing, it isn't standard

Slope will matter with load calculations. Apply the cosine of the slope to the weight to get the true load on the roof.

As long as you're talking span, it doesn't matter. Span tables and span calculators give you the right numbers.

I mentioned low slope because of how I'm framing them. It works well with low slope, but it isn't prescriptive.

Put in the ceiling joists.
Run a 2X4, 2X6, what ever peroendular to them on edge down the center.
Put rafters on top.

Ceiling joists and rafters both work to support the roof. The 2X12 on edge helps with the side thrust as well, similar to a structural ridge.

Steeper pitch will have a longer rafter but same span so thatís why pitch doesnít affect span tables.

It's just a suspicion. I've been wrong before.

Maybe 1.5" on centers will work....

Maybe. Find me a table with 1.5" centers and I'll look it up for you.

Re: The Wall Of SHAME!


We all know that it doesn't meet code. I've seen a lot of shoddy workmanship in this thread, but this is the first time that I said that it needed to be reported. It's too dangerous to ignore.

Photoshopped.

I’m really not buying that someone would actually do that. My money is on that roof coming off and someone thought it’d make a good pic. for the inter webs so they took the sawzall to it.

Iím going to agree with this especially because the lighting is so good and it look like they cut out a plumbing stack.

Ya, okay.

I think itís a legitimate WOS piece of work.

Iíll inquire a bit perhaps, but itís a strange day when we have to prove how inept people are.

Re: The Wall Of SHAME!


I personally wouldn't even consider that approach were I to demo out that roof.

Pull all the sheathing, maintain some bracing, then work your way from one side to the other, as you demo or lift each truss.

I've seen some pretty long rafters made out of 2x4 in some of the old houses around here. I did an attic to bonus room conversion on one of them and the deflection was 5" over 16'. That roof looked like a chinese pagoda with that much curve!
