Okay. I've heard tile can be a pain—knew about some of them but not all of what you said. It's probably a good thing there aren't a whole lot of them around because moss and lichen like shingle roofs plenty. :)

Yeah, basically all the grit that's on the shingle ends up, eventually, in the gutter.

I'm liking the idea of this steel roof. If it's raining at night, we can still hear it on our roof as it is, so I wonder what it would be like with a steel one. I know what you mean, though. It is a cool sound.
