Wow, so this is possibly about SYP?! I've been watching this item, because I'd never heard of "Life Pine". If Mr. Clark is correct about this being PT SYP (Pressure-Treated, Southern Yellow Pine), I'd be very, very wary.
Being a conservative guy, I often advise Clients that, "For any product that doesn't have a 30-year track record,
you are the "guinea pig"! Look at how quickly stories arose about plastic decking, and now cement siding. Anyhow --- for
SPT on a
ROOF? Sorry, but not a chance! I've had my fill of PT SYP on decks (
lucky to squeeze-out a 10-year life!), shed frames, etc. If the cedar is too expensive, I'd see a few options:
1. Go for 45-year asphalt-fiberglass shingles.
2. Go for cheaper shingles, or even roll-roofing,
plan on cedar in, say, 15 years, and save-up for it.
3. Look at metals, if that would fit the Design of the building.
Best of luck to you.

Subject: Cedar Roof Shingles vs. Life Pine
I looked online and there is very little information of value. (Check out the insulation value comparison to Cedar)
Note that the "50 yr warranty" is similar to standard asphalt shingle warranties - material replacement only for 15 years, then pro-rated.
This appears to be PT SYP. One would expect similar lifetime to SYP decking, maybe. It won't rot or be eaten by insects because it appears to be treated.
