Missing Ridge Board

[Michael W. Gault]

My wife says I'm guilty of it all the time...

No need to give out too much info, just the biggies and the recommendations...

People don't read much of the fine print anyway...

p.s. Almost a double needed... a Structural Engineer and a Licensed Contractor whose specialty is House Framing

"rafter ties" prevent walls from spreading and are usually installed at or close to the top plate, tying the bottoms of opposing rafters together. "Collar ties" are installed in the upper third of the roof and prevent uplift.

As Richard pointed out, the conventional side is really a shed roof, with the truss side performing the duty of a structural ridge in supporting the peaks of the conventional rafters. The force of the roof load is down, rather than out, as it would be if the whole roof were built conventionally, so a rafter tie isn't needed.

Info:...Oh, good Kenton, you supplied the info. I was on the phone a little long...but I scheduled the inspection.

I don't see collar ties to be an issue. The main issue would seem to be the load on the inboard end of the rafters, and the ability of however many nails there are to carry that load to the truss. That, if anything, is what I think should be evaluated.

Richard, I have built many a shed roof and always include collar ties.

Are you suggesting that if I built a 8 foot farmers porch on the front of a house and it had a shed roof that it would not require collar ties to stabilize the load bearing wall?

Just curious as to your interpretation of this scenario.

Thanks for the document larry. Interesting read. I sure wish all those framing books felt the same way.
