   I assume you are NOT setting the posts on top of the roofing, but on the deck. When I have done things like that I've had a sheet metal shop make up flashing boots for posts... a 4x4 "chimney" several inches tall that the post fits thru... and a flange at the bottom that matches the roof pitch. Same as a standard galv+rubber pipe boot, only it's made for the roof pitch and made for the 4x4.

   No matter what you do it's still a questionable detail.

   Thanks for your reply, David. I have attached the posts to the top of the porch roof sheathing (and into the rafter below) and am now ready to flash and roof with archetectural asphalt shingles. I have saw kerfs angled upwards in the posts about 4" up from the bottom which can receive the upper edge of the flashing or "boot" that you recommend. I could deteach them to slip a boot on at this point if I have to.Wondering if rubber roofing technology is appropriate here just to seal around the post--not for the whole roof?

   My point of view is slanted towards custom sheet metal because for a long time I had access to a mechanic who did great work and did it immediately. A handful of boots like that would be same day or next day, 26 gauge galv and immaculately made. If I was going to kerf the posts he'd bend some counterflashing to go with it.

   I do just like you said. But sounds like you need practice to tighten up your oorners
