I've been contemplating the remaining lifespan of this multilayer roof that's been failing some of the carpentry on my mother's roof and wondering about going solar with the next roofing. I wonder how robust these things are for standing on and how they cut around the gas flues and plumbing ventilation pipes and what not. Maybe they deliver blank tiles with no cells on them to cut into odd shapes and what not. If the price difference is close I'd go this route easily.
