Bungalow, back end south facing. I was unhappily on the roof about 5

I'd read that stringing a length of copper wire over the ridge kills
moss, so I did it. The moss returned on the back end of the roof, never
mind and ******** to it, I'm not going up there again. Since Autumn
chunks of moss have been falling down almost every day. Maybe the copper
wire takes time to work?

Yeah, I've heard that too - from enough "different" sources (possibly
here) that I was tempted when I was last up on the roof.

Wasnt there a contributor on here when usenet was still in short trousers
who manufactured shaped copper sheets for the the ridge as part of a
business? Scottish based ISTR
The components were a lot more substantial than a thin bit of wire.

Wonder if this is them.
