BEFORE AND AFTER PICTURES OF ROOF CLEANING SOFT WASH. EACH SIDE I TOOK A PICTURE OF 3 PHASES (BEFORE, DURING, AND AFTER ) ITS A CHEMICAL PROCESS THAT KILLS BLACK ALGAE AND MOSS ON THE ASPHALT SHINGLES. THIS MAY TAKE A FEW COATS. AND AS YOU CAN SEE, THE REULTS ARE AMAZING !! (THE BROWN DOES WASH AWAY )
