Boy, the gutter industry is shady! I am hearing from some people that a surface tension based, clog-free gutter system works fine for ceramic tile roofs and from others that the tile roof causes rivers of water that run over the edge of the gutter and will not allow the system to work properly. Don't know who to believe!! Anyone got any thoughts on this?

Is there anyone that sells flip clean gutters in your area as I have them on my house and they are wonderful, you can clean all your gutters in about five minutes.
