Cleaning Seneca Fiberglass Roof

[Madjack06]

Wonder what you use to clean your roof. I have black spots (mold) and would like to get it clean before the bad weather starts here in VA. Many thanks, John

We use a mild mixture of Simple Green and warm water.... then a soft bristled brush on a broomstick. Blow dry with a leaf blower all around the AC units and vents before you fix any seals.

I do my regularly and just use a car wash with a wax in it. For anything stubborn I just hit it with Simple Green and a brush.
