I have never stick framed one like that, it would one day to build it with trusses. Even that takes some head scratching.

Your walls should be sheeted or you should have angle braces on the walls.

But it is looking good.

If you look close you'll see 1/2" rods from the top plate down to the curb. The walls are very secure.

I wouldn't trust it, but if you think they can't move.

Re: Tying addition to existing roof line


The rods thread into these embeds in the curb 48" o.c. and at each side of doors, window and corners. The walls aren't going anywhere.

Re: Tying addition to existing roof line


Neal,

Haven't checked with the engineer on cutting the beam yet.

But I have another question: Should I use Zip System sheathing or good old fashion 7/16' plywood and tyvak wrap. I'm thinking this is a plywood and wrap job. No need to spend extra $$ on a garage/workshop addition. Agree?

I have no experience with Zip but either system, it is all about proper installation and flashing. I don't see an advantage to adding expense if you do the other properly.

I've done my YouTube research on Zip System and it does have some advantages but plywood/wrap is pretty foolproof and cheaper.

Nothing is fool proof but any problems we see are are about poor installation and if you use zip you still have to join and water proof to the house so you would be doing both.

Re: Tying addition to existing roof line


Here another question,

My current roof uses 1 x 6's not plywood. Therefore when I tie the new addition's roof into the existing roof there will be a visible line which will telegraph through the roof surface. To avoid this I need smooth out the transition. I'm thinking I need to lay my first piece of 7/16" plywood against the 3/4" and then over lay a single sheet of 1/8" underlayment boards and an extra layer of felt paper to ease the transition. Then at 4' out I'll delete the underlayment and use just a extra layer of felt. At the 8' mark I'll just be using the 7/16" with a single layer of felt and continue out for the rest of the new roof.

Thoughts?
