(Residental) Rafter to Ridge Condition?
 
I recently raised an ex. section of roofing (dormer) from an 8 to a 3 pitch running along the end of the ridge on 1 side of the ridge I connected 2x6x16 @ 16"o.c.

My question is: Where the rafters meet the ridge they are above the ridge by <1" and not flush. Is this a problem? I can tell you that I used a hanger for each one and the are toenailed at the top and on the sides.

Why are the rafters 1" above?

Not sure what any other advice will be, but if you don't intend to change anything, cut the tips off flush with the angle of the rafters on the other side of the roof.

Cut the rafters so they fit. Im not liking that roof design too much TBO

That should have been posted before mine. I was trying to be generous. Construction Master makes a great calculator for that.

In that situation i would just measure the birdmouth to the ridge and transfer it to the rafter.

Its the 3 pitch i don't like with no support really. I can't see that not sagging under load. You have a lot of outward pressure on the front and back wall with that set up. What are your plans for that?

What good is a CM if they can't read a tape? :laughing:

Looks like OP used the existing roof deck as his helper to hold the other end.

I'll bet the rafters are running wild on the other side with no seat cut. :wink:

Also what is that span your running 2x6's on a 3 pitch?

notmrjohn 08-27-2012 07:11 PM

Calculator? You mean with buttons and stuff and not rusty charts on a framing square?

Hammer450R 08-27-2012 07:17 PM

Its not a dormer, there is nothing to hold it up. No room for a collar tie.
Ridge props? lol

I'm not a framer by any stretch but should that ridge beam beam have been beefed up, sort of like a header.
Looks to me like it's going to sag in the middle.

Hammer450R 08-27-2012 08:08 PM

There is still nothing really holding it up, Maybe a massive beam from end to end propped all the way to the basement...Id bet the outside walls are already leaning out.

A couple of things, I don't think you are attaching to a ridge board in the picture, it looks like blocking between rafters to me.

Also, 2 x 6 @16" O.C. spanning 16' is not prescriptive for sure. I think you need this redesigned and submit for permits.

The rafters you cut, do they continue from the ridge to a wall plate?

Where are you located by the way?

I used the wrong hangers... I switched them at the last minute.
