Jeff - figure out your clear span - from the ridge to where it meets the outside edge of the top plate. Then use this chart - check on the wood availability (southern pine structural). If the wood is different then let me know what type and I can run this again for you.

Southeren Pine 2x6 with 24" oc and a snow load of 20 psf = 11-2" max span.
Southeren Pine 2x6 with 16" oc and a snow load of 20 psf = 12-9" max span.
Southeren Pine 2x8 with 24" oc and a snow load of 20 psf = 14-8" max span.

If your snow load is higher, let me know that also.

In the first sentence I said use the outside edge for your span. Since you are a non-carpenter type (grins) just allow the rafter to rest on the wall and then use hurricane straps on each one. The use a tie (2x6 or 4) across each rafter. Kind of like a squatting "A" where the horizontal on the "A" is the tie. I can draw you a picture if needed.

We can either talk and I can send drawings.
