Re: Saltbox Garage Roof Frame?


Joe's way is done all the time, you just need a ridge beam, collar ties or both. I would rather have the ridge beam and probably have both to get the ceiling down.

Either way he is going to need a beam, although the ridge beam can be sized smaller than the beam holding up the floor.

Here is another quick drawing like Joe's except knee wall is 6' tall so some normal sitting windows could be put in.





Forgot to add collar ties/ceiling joists shown are at 10' and 12'.

Yes Joe that is the style.
Wow nice help on this guys
I think I can design with this help and maybe get a good frame system I want.
Still not sure of the way I will support the 2nd floor at the long slope side, but indeed I am going to get it from everyone's help here.
I will try to post a Sketch up drawing I was working with.

If you're going to frame it the way you have it drawn, you will need a big beam across to carry the roof load and floor load. Your way definitely lowers the overall height. If you want more headroom in the above room, the way I drew it will do that for you and you won't need such a big beam.

The more I thought about it, the more I realized I do infact see you method most often. I guess my mind was just looking at that picture differently the first time around. With the sidewalls tied in and the collar ties you wouldn't have anymore of an issue than you would with a traditional gable frame.

Re: Saltbox Garage Roof Frame?


Like I drew in my first pic and what Joe said, a big beam.

We did a retrofit something like this years ago. The building was a gambrel roof barn, and they wanted to add a shed style wing on the side of the barn with big doors to drive equipment into barn and remove the existing wall and have a clear span to get further into the barn. This wall was 36' long, and we used a 36' x 30" x 6 3/4" glulam to hold roof and loft load.

We also did something similar in 1983 except it was only a roof load on a commercial structure. This was a 40' wall and same thing added a shed style wing to the building at the bottom of a 4/12 roof pitch. The glulam for this was a 40' x 36" x 8 3/4".

So remember you will have to calculated half of the floor and roof load, plus whatever you are putting up there.

Re: Saltbox Garage Roof Frame?


Well I see the light now.
Thank you Joe,Kgmz, and everyone.
I will build using Joe's framing as it seems to be the best and strongest. I will not use my idea of intersection with the rafters with floor joists as it would require as Joe and Kgmz said a very large beam.
Thanks everyone

I wanted to get the crete in before snowfall.
Guss I missed it. 14 inches put a hold on my project.
Maybe we will see a warm spell in January
Thanks
