I hope I can describe this properly. I have 16' x 16' picture frame deck . At each end , perpendicular to the main decking , I doubled up 2 x 16' joists together, one for the main decking to land on and one for the deck board that frames the deck . I then put joist tape over both .Now I think water is just going to sit on this tape at the end of the main decking boards and just rot out the ends . I had an idea to drill 1/4" holes straight down between the 2 joists at every deck joint for water to drain ,I' m thinking that would increase the chance of the joists rotting Any thought or advice would be appreciated

So a little over a year ago we tore out our existing wood deck and replaced it with a concrete patio in addition to resetting the patio roof posts according to code. This was the first major project I had paid for as a home owner and probably should have had someone else do the final inspection with me but after a while I started seeing some potential workmanship issues I should have asked about. Below are a couple of pictures showing some examples. Anyway, what I am really concerned about is a huge crack that's shown up on the edge. Is this something that should be popping up this soon? Also, what's the best way of fixing this? Thanks for any input! [url=https://imgur.com/pgkJzKC][/url]
