roof construction


I am going to build my own little house in an area where it snows. For a snow load, I am going to use 2x6's as rafters but do I need to space them on 16" centers or can I go on 24" centers? Am going to use tongue and groove for sheathing.

I don't know what your spans or pitches are, but 2x6 rafters are awfully small. And always frame 16" o/c unless you're using trusses. Certainly you're building pursuant to local building codes, are you not? Is your decking 3/4" I assume?

I don't think he wants to go to school. I think he just wants to build a roof.

You don't provide nearly enough info. The span, pitch and size of sheathing are all things that have to be considered. You can take that info and find out if 2x6 is strong enough. Unless this house is the size of the unabombers shack in the woods, 2x6 is probably too small.

Thank you for the response. The roof area is only 500 sq ft. I want to use 2x8's for rafters on 16" ctrs, 2x10(doubled) for ridge beam, 3/4 t & g roof sheeting. Also, the pitch will be 5/12 or 6/12. Until I can get ibc codes, I think this will be fine???

They probably will be OK, but you will need the local codes for sure. Also, why the double 2x12 ridge? The ridge isn't really structural, And doubling it, or even making it 2x12, won't make anything stronger.

The OP said ridge "beam", not ridge "board", so let's assume he means what he says, in which case he may well need a double 2x12. Presumably he has done the calculations and computed the required size of the beam and has sized the support posts appropriately.

If this is going to have a flat ceiling in it, all you need is a single 2x10 ridge, as it's not really doing anything. If it's vaulted, a double 2x12 or a 12" micro-lam, depending on the span. Must have more info.
