We have a lot of moss on our roof. Does anyone have some good ideas for killing it and keeping it from growing back?

Call a roofer unless you're *really* a DIY kind of person.
Get a Galvanized flashing installed that hangs out under the ridge.
Somehow, the Galvanized stuff eliminates the moss/mildew by magic. (Look around your pipe vents,,,, no mildew under them, huh?)
Go for it.
Asphalt or composite roof tiles can easily get moss growing between them. This is a page about removing moss from asphalt roof tiles.
