There is an ongoing argument as to whether or not one should pressure wash a roof for mildew and moss removal. After spending many years trying different methods including many different moss control agents, zinc strips and pressure washing, it is the opinion of LL Supreme Green Home Services that pressure washing wins by a mile! A pressure washing PROFESSIONAL, that knows how to properly use his/her machine, wand and correct tips, can pressure wash a roof with as little as 500 psi (pounds per square inch) pressure. That amount of pressure does absolutely no damage to any roof including asphalt. There will be no damage whatsoever to asphalt shingles nor does it remove any granules from shingles. If it did, we would find granules in the eavestroughs along with all the moss and mildew etc. that we have already displaced. Moss control agents can take weeks and they tend to look patchy. Zinc strips depend on the rain to wash the zinc evenly and consistently down the roof, and that just does not happen. Rain finds its own way down a roof. Because of this, Zinc strips tend to leave lines on your roof as well as leaving a lot of moss.

The only way to make a roof look like new again, is to use a pressure washer with the correct low psi and a 45 degree fan tip. Pressure washing the correct way, is by far the best and most cost effective solution.
