A local neighborhood’s covenants forbids metal (standing seam) roofs. If I decide to build there, I’m looking for longevity and recycling and trying to anticipate life cylcle costs.

On the one hand, I’m thinking of the GAF Timberline “cool roof” asphalt shingle with a “limited lifetime” warranty. Locally prices run about $160/sq.

But I’ve also found these: “Stone Coated Metal Shingles.” There are several mfgs online. But I haven’t found local contractors who have used them or who know about them. They seem to run between $250 — $300/sq.

I wonder if anyone here is familiar with the product. Here is one:

And the mfg’s product “comparison”:

I’d appreciate opinions re the live cycle cost you’d anticipate, as well as any issues I should anticipate in installing them (in addition to the up-charge contractors will want for an unfamiliar product).

Thanks for your opinions!
