nice pictures, I'm guessing you have some olly screws holding those rafters down on the plates. But I don't see how the plates are secure on those posts . I think I see one peg in the bottom of one brace's tenon but not the top. If you get one of those hurricanes, what's keeping the entire roof system (with the plates) from sailing away?
There are tenons on the top of those posts and braces aren't there?
