Great tips above, especially about inspecting closely—been there, done that, haha. A few quick points I'd add:
- Check if your area has any reclaimed building material stores. I've found some surprisingly good-quality metal sheets there, usually from demo projects.
- Consider coated or galvanized sheets if you're aiming for longevity and less maintenance (rust is sneaky).
- Ask suppliers about recycled content and sustainability certifications...good roofing can also be green roofing.
Good luck—hope you dodge the warped-sheet curse!
Solid points mentioned already, but I'd be cautious about reclaimed sheets. I once inspected a roof made from salvaged metal—looked great at first glance, but underneath the coating, corrosion had already started creeping in. If you do go reclaimed, inspect extra carefully and maybe even bring along a magnet to check for hidden rust patches. Sometimes paying a bit more upfront saves headaches down the road... learned that lesson the hard way.
Good advice on reclaimed sheets—I've had similar experiences myself. A few years back, I helped a friend install some salvaged metal roofing that looked pristine at first glance. Within a year, we noticed bubbling paint and rust streaks appearing along the edges. Turns out moisture had gotten trapped beneath the coating, causing corrosion from the inside out. Your magnet tip is clever; wish we'd thought of that earlier.
Still, reclaimed materials can be viable if you're thorough with inspections and selective about your sources. I've seen some excellent quality reclaimed sheets from reputable salvage yards or demolition projects where the metal was properly stored and treated. But you're right—it's definitely a gamble, and sometimes paying extra for new materials is worth the peace of mind.

Couldn't agree more with this. I've had good results with reclaimed sheets, but it really comes down to doing your homework beforehand. One trick that's worked for me is checking the underside closely for any discoloration or uneven textures—usually a sign moisture's been hiding there. Takes extra time, sure, but worth it to avoid headaches later... Glad I'm not the only one who's learned this the hard way!

Haha, isn't that the truth? Ever had one of those "great deals" turn into a weekend-long nightmare? Been there, done that. Another thing I've learned (the hard way, of course) is to double-check around any old screw holes or edges for rust. Even if the sheet looks good overall, those sneaky rust spots can spread faster than you'd think. Also, anyone else notice reclaimed sheets sometimes have weird sizing? Like they're just slightly off standard dimensions... makes fitting them a bit of a puzzle. Still doable, but definitely something to keep in mind before you commit.
