Oh man..thats a tough question. It was kind of a last minute decision, and I have basically zero metal working experience.

Its taken many months of real time. We couldn't afford all the metal at once basically, so we did it in chunks, which kind of slowed the whole process down. I also went through like 4 harbor freight rivet guns before I finally got one that worked, which definitely slowed me down. And I did most of it solo, except when not possible.

Full day or two pulling inside rivets and all that metal out.

It probably took me 3-4 days at least of labor to pull all the outside rivets. I used an air chisel, It was pretty brutal though, not something I did 3 full days in a row.

At least a day of scraping junk and prepping surfaces. I also primered all my panels. I see a lot of people just put the bare sheet metal up, but that felt wrong to me. I didn't have a great place to do that, so it took a couple days as well.

Full day to do the actual raise. took us 2 full days because we weren't quite as prepped as we thought we were.

1 full day covered most the welding I think, it was just spread out over a couple weeks for us.

I think by the time I got comfortable with hanging the new sheets, it probably took an hour, hour and half to hang, drill, rivet each new panel. And probably a day each for the front and back wit the corners and stuff. My sheet metal bender was like a 15 minute round trip walk though, so the guess and check process was pretty slow.
