Howdy all,
I've been following a previous thread entitled “overhang questions,” but it never really seemed to get where I thought it was headed …
It's a very long story, but we got a good deal on a set of roof trusses a while back (the truss maker got the order wrong). We've built a small foundation on wooden pilings (shortened utility poles) and are now considering using the roof trusses to speed things up.
The trusses I'm referring to are 24 feet long and 9:12 pitch (10 finks and 2 gables). The foundation is 10 feet by 12 feet, which brings me to the point: If we install the trusses over the short span of the building -- the 10 foot span – how much unsupported overhang is safe?
The idea is to “shift” the trusses so that 3 feet of truss overhangs one wall and 11 feet overhangs the other wall. Naturally, the 11 foot overhang will be supported (by a post and beam system in this case); therefore, it’s the 3 foot overhang that concerns me.
Given what I’ve described here, does 3 feet of unsupported truss overhang seem possible?
Sketch of proposed roof below (with any luck) … Thanks for your time.
