I'm a heating contractor, but I built my own home, so I know simple construction techniques. But this has me scratching my head.

I need to build a deck onto the back of my home. About 12'x40'. A friend of mine is kind of a demolitionist, and offered to me a bunch of 3.5" x 5.5"x16' double tongue & groove cedar planks from the roof of a building he salvaged.

I have a few questions for those who know before I build this thing:
> Is this good material to use for a deck? I live in Idaho and it will likely have up 3-6" of snow on it for a month or two each winter. Double TG planking will create a watertight deck, no? As long as I have .5"/12" slope, am I ok?
> Using this material, could I build it as a simple span deck of about 10' with a 2'-3' overhang? (Did I explain that right?)
> Any other "gotchas" to watch out for?

I'm thinking of having an architect design it so I don't make a big mistake, but if you guys give me green light on the above questions, I'll probably just get started.

It would be better to trim off the tungues and face fasten the material

T&G decking outside drains the same way as as face fastened material. It will not be water tight and a Person dosent want it to be. John
