I currently have joined under flashings and window flashings on the house. I'm about to replace the windows and thought to replace all the sheets at the same time.
How do I best join a window flashing with an under flashing without having to call the sheet metal worker?
Picture of how it looks today.
If you're planning to make your own window sills with an upturn, you can make a lock seam, which is simple.
Otherwise, you can cut the sheets so you can hook them at the bottom and just overlap them by a couple of centimeters. With a bead of sealant, it will be at least as tight as a lock seam.
As for the rest, I have the latter on my house façade without sealant. Made in the '70s by a house factory without any love, it's on the list to redo but I'll probably postpone it until I repaint.
Bumping up this thread a bit. The windows are replaced, and all old metal sheets removed. How can I solve this best? If I use flashing that fits in the window's groove, it won't align with the nail battens. If I use a separate sheet behind the panel, that sheet and the sheet under the window won't align. The distance that differs between the nail batten and the groove in the window is about 20mm.
Tips???
