What is considered soft washing psi? PSI under 100? What is the average psi coming from a residential faucet? In some cases, we may have to wash/rinse the surface, but should a customer ask I would like to be able to tell them what soft washing consists of. Thanks, Mark
I know this may not be answerable, but do you think the psi of a hard rain is? I guess I am trying to figure out an acceptable or safe psi to rinse a roof should it be needed. If I advertise soft wash, I want to be sure I am using softwash psi. The asphalt tech bulletin says no high pressure sytems are to be used. That is too general and vague. I need more specifics. Thanks, Mark
I called the pitchwitch company today just to see what its psi is...They said 500. I cant believe guys get away with calling it low pressure. Yeah, maybe for a pressure washer its low, but for a roof, no way Jose!

We never use that kind of pressure for roof cleaning in tampa I have seen roofing shingles damaged by a garden hose with a jet tip.
500 PSI with the pitch witch, 800 PSI with the surface cleaner-on-a-rope-on-a-roof that the franchise guys use.... Imagine a one inch square on your foot, with 500 lbs on it!!
That's scary!
Consider a 12v pump (Fatboy in my case, might upgrade this year) at 60 PSI at ground level. Now push that through 200' of hose, mostly coiled. Now push that head 1 story, no make that 2 stories. Now let the chem rain down on the roof like you're watering a fragile flower garden.
