I have a slate roof job coming up and have never cleaned one of these, can you advise on process, strength, special considerations needed! Also I assume rinsing is going to be needed am I correct? How many applications do you think it will take?
Gregg a 4% mix will clean that up just fine. Do not rinse and use a light amount of soap. Let the rain rinse the roof. ;Look up slate roof cleaning pitman nj. There are before and after pics of a roof we did last year. Also call if you have questions.
