Does anybody know if installing these at the ridge top of a roof will prevent streaking? I know the roof has to be cleaned first. But could they work to prevent it from re-occuring?
I googled it and saw alot of information saying they do work.
I saw alot of different p.w.'ing companies all with the same information saying they dont work.
Can anyone else shed some light on this subject?
I was asked about it recently by a potential customer. She found it online.
Thanks
