This was awesome! I loved every minute of it. These are the types of things that I enjoy learning about because as you say the smallest thing will go wrong and you’ll have one hell of a time trying to figure out how to fix it lol.
The bend in the flashing makes total sense. Those are the small things that people don’t think about much but if you want it done right you have to put in the effort to do it. I would have definitely done what you did and put the upgraded aluminum on it. Might be overkill but some of the stuff at the store pre-designed for this gives you about the amount of money you spent on it which isn’t a lot.
Thanks for stopping in @cmplxty.
Having done hundreds of roofs while in business, I learned early on that product and addressing even the smallest of issues is the only way to roll.
A few extra bucks spent on items that will last longer seems like the right move. It makes no sense to me to install a shingle with a thirty-year life span and then use an inferior flashing.
Have a great weekend!
