New Shed Gambrel Help
Hello, I was wondering if I can get some assistance with my roof design.
I'm in the process of building a 12x16 shed. I have Googled everything from day one on this project and I'm almost Googly eyed from so much information and a variety of information and even misinformation.
I have all the walls up (2x4x8 16" center)and I have 2x6x12 16" center across the 12' span and attached them using only hurricane clips.(Not sure if i still need to toe nail them in on top of the wall)
My next step is to lay down my 1/2" Plywood on top of those joists and then start attaching my gambrel roof.....but I haven't figured out my gambrel roof style/dimensions yet.
I decided to go with a gambrel roof so I can have some storage space for the little guys toys, seasonal stuff, etc. I don't intend on having it as a play area or anything such. I live up in northern Canada. And we get alot of snow....alot. According to the roofing charts here it can be up to 52.5 LBS PSF. http://www.hsh.k12.nf.ca/technology/...le27/index.htm
I know gambrel roofs are hexagon and inside a cirlce and each cut is 22.5 degrees and adds up to 180 degrees....etc(thank you google)
But, I want to know if 2x4 is going to be strong enough with just 1/2" plywood gussets on each side where they join. And I don't want to go 6 ft high. It's said the height is half with width which is 12' in my case. And I don't want too flat of a roof due to the snow load.
I'm going for this exact style of framing.

I just need advise on the dimensions of the gable/angles etc.
Sorry if it seems I over engineered everything, but I want to make sure it's not going to collapse and withstand our winters.
When I built my 12x8 Gambrel shed, I used:
1. 2x4 as my wall studs but used 2x6 for the rafters, 16" O.C.
2. 3/4" CDX plywood (not OSB) for added strength (that way I did not have to use h clips to support butt joints). It's my personal believe that plywood handles water better than OSB
3. A ridge board, instead of butting rafters against each other with a gusset plate, for (perceived) extra stability
As far as the roofing height is concerned, make sure you stay compliant with your local zoning/building codes.
BTW, what is the height from the floor to your ceiling joists?
