Reading this makes me feel a little better about my own struggles with flashing. I went into my first roof repair thinking Z-flashing would be this magic fix, but man... lining everything up while balancing on a ladder was not as easy as the YouTube videos made it look. Ended up with a tiny leak near the edge that took forever to track down—turned out I’d missed a spot with the sealant. Lesson learned.
I totally get what you mean about needing three hands. Sometimes I felt like I needed an extra person just to hold things in place while I worked the drill. But when it finally came together, it was super satisfying, and it’s held up through some crazy storms since then.
Don’t get discouraged if it doesn’t go perfectly the first time. I definitely had to redo a section, but it was worth it in the long run. It’s one of those things where you get better (and faster) the more you mess with it.
I get the satisfaction part, but honestly, I’ve seen a lot of DIY flashing jobs that end up causing more headaches down the line. Sometimes it’s not just about getting better with practice—if the metal sheets or flashing aren’t sized right from the start, you’re fighting an uphill battle. I’d argue it’s worth spending extra time planning and measuring before you even get on the ladder. That’s saved a lot of folks I know from having to redo sections later.
You nailed it—flashing’s one of those spots where even a tiny mistake can mean water sneaking in and ruining your day. I’ve seen some wild stuff over the years… one guy tried to “make it work” with leftover siding and a roll of duct tape. Didn’t end well for his living room.
Honestly, I’m with you about planning and measuring—nothing kills your momentum faster than realizing your metal sheets are too short halfway through. I always tell folks, measure twice, curse once. If you’re buying from a big box store, double-check their stock sizes because they don’t always match what you need for valleys or tricky corners. Some local suppliers will custom-cut, which saves a lot of headaches, especially if your roof’s got weird angles.
I get the DIY urge, but if you’re not 100% sure on the sizing or layout, it’s worth grabbing a second opinion before you break out the snips. Redoing flashing is way less fun than getting it right the first time.

That one always gets a laugh—been there myself. You’re spot on about custom cuts, especially for oddball roofs. Sometimes the local yard costs a bit more, but it’s worth it when everything actually fits. Nothing worse than redoing flashing after a rain.
You nailed it about the local yard being worth the extra bucks sometimes. I’ve tried ordering online to save, but ended up with panels that were slightly off—nothing like trying to force a square peg in a round hole. For weird roof angles or older houses, those precise custom cuts really do make life easier. Plus, if something goes wrong, it’s a lot less hassle to deal with someone local than trying to ship stuff back and forth. That said, I still check the big box stores for standard sizes when I’m working on sheds or simple garages... sometimes you luck out there too.
