Only thing that I could say is leave half of the top end or atleast a few inches so you can put I bit of cutting on the end thats overlapped. Instead of having a straight seam on the corner that leads to the material behind it. Same reason why you leave a bit of material on the flat section.
@@cw7700 like, the two rectangles that he folds down, he goes and cuts them flush where the back is. He should leave one of the sides there and fold it around the corner so he has a nailing spot on both sides to keep the two sides tight against the wall. And he's able to some good caulking from the top of the flashing, down to where a pinhole would be, and under the one side of the flashing that's sitting. Caulking isn't exposed to uv rays so it'll definitely last 20+ years if it's a good quality caulking Don't get me wrong he did a great job but it's just the tiny details and reassurance with caulking that make it stand out compared to the thousands of other people who do it like that
@@cw7700 He's saying that you should have left an ear on the topmost vertical portion of your corner cut on the left side to fold over at a 90° underneath the right side when folded over providing an overlap instead of an open cut with nothing bridging the gap in between the two intersecting sides.
Ya gotta put a return on the apron upstands so you can caulk and seal. So water has no way of working through. Under flashing won’t stop the water after a couple months. All joins must be lapped by adjacent materials.
Upstand/stop end. Just leave extra 100mm on that plain of the flashing, score the underside, to allow it to bend, bend it, then cut to the required height. You leave a bit to go around the vertical leg too. To seal it all off. But my explanation would probably confuse you.
@@oldsharke2840 well this video is not in Poland, and can you send a link that shows in the rules and regulations that if you use sealant in Poland your not a roofer ? I'll wait for the link you provide, cheers
@@NightlifeReALIty it is compliant in the uk and until I get called back to see a water leak I’ll continue to do it like this, been ok for the last 20 years
