  • Nooooooooo! Not a pressure washer!!!!!!! LOL!!!

  • This is the worst and most damaging way to clean a roof.

  • Here in Washington state chem alone will not be enough for some roofs...High pressure air or low pressure/high volume (8 GPM) wash is the way to go so long you know what and what not to do, other wise its a filthy yellow and orange mess of dead moss. Granted in this video it looks like he is using low pressure and or low volume, If it were me I wouldn't get nearly as close and also keep a downward angle as to knock the moss off.

  • That's so wrong. That is the epitimy of how not to clean a roof. We use a 12v pump and a bleach based solution, no dead plants for 11 years (since we have been in business) we use LOW pressure not a pressure washer as seen in this video. Sorry for bashing.

  • Pitchwitch recommends around 60 lbs of psi.

  • Very true. By choosing the proper chem all that is needed is a rinse from a garden hose or a gentle rain.

  • That's a fast way to destroy a roof with a pressure washer no matter how low you set it. Try using a 12 volt pump with chemical instead. Just a word of advise from a professional to a professional. 11 years in the roof and exterior cleaning capitol of the country, Florida.
