Ahoy! Roof Experts
What is the best way to handle a roof on an addition?
I have a small house that wants an addition made to the rear forming a T shape. The old structure will retain as much of the roof as possible when the addition is added.
The old roof is a 4 pitch and is stick made. The new roof is
is 6 pitch with trusses. I need to draw the old structure in order to get the addition plans so I must build the roof planes and the framing on both new and old.
For the permit I need to show the new trusses and how they tie into the old roof rafters.
What steps would you recommend I take to make this roof plan turn out correctly.
Appreciate your thoughts,

Think I would build the existing house roof first.Under structure uncheck roof over the addition..Frame it and then do the addition manually..
I have not had to much experience with trusses..
Forgot to use the tool to get the trusses to follow the valley..
If your going to stick frame the over,might be easier to auto frame and delete the common rafters...........

Good Morning folks!
Let me show where I am now with a little visual.
I framed just the existing structure and then added the roof plane and trusses on the addition by hand.
Now this looks good but does not show the connection. Some say this area is to be a stick build others says add small trusses across the existing rafters.
If I add trusses how? and If I want to show the stick tie how?
Oh, please note in the top view that the existing dtructure is 4/12 and the new is 6/12. This makes the need to adjust by hand the ridge points.
Which way to go and how?
Thanks , PaulLast edited by pktraylor; 03-25-2007 at 06:45 AM.

Hi Paul
What do you want to use?Could you drop the pitch a little?
I'd have to watch the tutorial on the short trusses for a refresher...........

No, The pitch is set now at 6/12 and a scissor truss with 3/12 ceiling.
I guess I would like to investigate all the possibilities.

Paul,
I was under the impression that truss systems are engineered by the manufacturer. Have you considered talking to the manufacturer to get the information you need? Just curious.Tommy Blair

If you're changing pitches, remember to pull your tails in on the 6/12, or your gutters won't line up (unless you want it that way). The aggrevation and cost of trying to use trusses for the tie in (you have to be EXACT, and you're existing pitch has to be exactly what you predict, with no sagging etc), is just not worth it, best to just "california" over the existing roof.
My question is, why change pitches? If you keep it the same, you won't have that bird beak at the ridge where the roofs meet. Just curious.
Sent my post before I saw the scissor truss comment, sorry, the drawing does not show the scissor.Last edited by PhoenixConstruction; 03-25-2007 at 07:19 AM.

You need to use a truss base..
Trusses are ordered?Always have a structural ridge to stick frame it..
Chris uses trusses a lot...........

As a framer (not speaking as a Chiefer)....for an addition like that, if I would want to have the fascia match I might prefer hand-framing the roof rather than trussing...there could be some hidden variables in the existing framing that you just dont know about until you cut open the roof....

Depends on the size of the room.Might have to be a very big ridge..

Here is what one carpenter would like to do. Truss the new addition up to the eves and then stick the attachment.
What are your thoughts about this idea?
