Hi,
I guess by tarping my
Boler over the last few winters I've invited some mold to grow on the roof, nothing too serious but lots of small dots of black all over the roof. Ok I guess it is alot.
So my plan was to put some degreaser spray on the roof, let it settle in then pressure wash it off. Hopefully that will do the trick.
Has anyone else had this issue and what have you done to get rid of it.
Cheers
