Zone 5 – Ohio, ground snow load 20psf…

Looking at roofing options for my remodel.  I got a quote from a pro on standing seam metal; it was about $40k which is substantially too rich for my budget.  Asphalt shingles are obviously the low-cost default, but if there were a better option that I could afford, I’d prefer something else.  Due to the complexity of my roof (a couple dormers, areas with different pitches), I don’t feel that I could adequately do standing-seam metal myself — if it were a simple roof, I’d just order pre-cut panels and do that.  Structurally, I don’t think the roof can support any kinds of tiles (also not common in my area).

I recently came across the idea of metal shingles (also mentioned in a couple articles here, namely https://www.greenbuildingadvisor.com/article/choosing-a-metal-roof).  This seems to be the best of both worlds — the shingle form factor means they’d be easier to self-install, while offering the durability and reduced environmental impact of metal.

The first company I ran across was Reinke Shakes — but these are a through-fastened shingle that requires Grace Ultra under the entire roof, which makes me dubious on the long-term durability.  They do, however, sell direct.  There’s also a number of nicer-looking, interlocking / concealed-fastener products, such as Permalock, Interlock, and ATAS International — but I haven’t found pricing or indeed even a way to buy these, other than “here’s a referral to a roofing contractor.”

Other than the general debate of asphalt vs. metal, I’m wondering if anyone (A) has specific experience with or recommendation of any of these brands, and (B) knows how / where to buy these without starting a fake roofing company.
