Structural ridges?

If you laid two structural ridges into the main roof section, with each ridge's height at the dormer's ridge height, and then piggy backed higher to get your main ridge height, you MIGHT clear span the main ridge line. Your main ridge rafters would die into the structural ridges, (there would be two, one on each side) and then carry on the plane with short rafters laid on top.

You could also make the dormer's ridge structural too. You then have two "T" shaped ridge formations.

I don't know how beefy that LVL would have to be, but I think it could be done (quad 14"er's...just a guess) for 44' clear span. Otherwise, you would just need one support column under each intersect point at the "T".

Scratch the 44' span. You're spanning the 37' with a main ridge. (Mixed that up!) So, one column at 18.5' at the T. Totally doable.

No problem!

I got the impression that you were partial to stick, so I offered a work around. If you've found a solution, great!

I guess your post was more about "what do you think?' than "what can I do?"

Sorry about that.

And yes, I've done hybrid roof builds. They work out fine.

I designed and built one myself. I would not do it with trusses. I think you'd lose too much headroom from your perspective. I can't find the pdf files I had ATM. It's been a few years. I'll keep looking for them.

You have an upper and lower ridge there. What I did was run full length ridge beams on both. Ran it right through (or under) the other one.

That's a better solution than mine sir!

I don't know why I didn't see that. :blink:
