ahh!... perfect, the Simpson catalog! i should have thought of that! ha
Then i can plan the details before driving into town (about an hour and half from here).
I like the metal standoff and was thinking of putting washers between vertical joints? or maybe a piece of roofing felt, but i don't know if that would help or hurt. Now i'm thinking maybe a shingle would be better?
(not pressure treated but it will be under the roof and i'm painting the facing/undersides before fastening anything together.)
Thanks for your help
