I’m finding that a metal roof is about twice the cost of asphalt-based roof. And i’m not all that convinced that metal roofing is as trouble free as it might seem. sure the metal will hold up, but the installation has potential issues (seams and protrusions). And i have read about sand filters that are essentially live filters that utilize bacteria to clean the water. They seem to be used mostly when people want potable water, and they appear to me to require some care and monitoring. More involved than i am willing to get.
Thanks for the link, talaki34. Some good info there!
