OK, I don't remember. Just sold a roof cleaning with copper gutters. Should I do anything extra?
Thanks for calling today Mike! Like we suggested, you can use a gutter cane you can buy for 20 dollars at Lowes. Art Oliveri uses these. Next, use big sponges to plug the gutter downspouts, then turn on the gutter cane's water supply. This will cause the gutters to flood and spill over, diluting any chemical that gets into them enough to be rendered harmless, and watering the outside of the copper gutters, at the same time, during the roof cleaning chemical application.
