High cost plus a dearth of design choices will still keep "normal" folks from buying this roof, the virtue signallers will buy it just as they bought a Prius to sit in the garage alongside the H2. It's a limited application roof, so if I have a standout Tudor style home with a chic correct slate roof for 545k and then down the street is another Tudor with a blaugh ugly Tesla roof for 526K, I'm buying the correct roof and I'll find other ways to prove my "environmental sensitivity" other than coming home to a blaugh ugly, frikin 5k per month Tudor, with a fat, bulky, gray, fake lookin' and fake it is, gawd dam where'd you get those fat ass ugly shingles, roof!!?!???!??.....
now.....a bunch of gov't subsidized Leviitt tract houses in the flatlands of Iowa?!?!?!?
yeah, they'll all be virtue signalling, gov't subsidized, blaugh ugly roof domiciles,.....
plus strip malls, empire zones, special economic zones and anywhere else that tax exemptions, rebates, subsidies, etc. are a better concern than aesthetics,....
you know, like she sheds,.....
