After power washing siding why marks left.
It can cause water to build up in your walls or attic.
After borrowing a power washer we tested it on the backside of the house with no problems.

Your best bet is to hire a professional to pressure wash your siding but you can also do a quick cleaning yourself.
A good amount of pressure is needed at least 2000 psi and a volume of 3 4 gallons per minute gpm output.
High pressure will damage and even chip concrete.
A commercial pressure washer which is what most people would rent over the weekend to tackle this chore can blast water up to 3300 psi.
This happens due to age and sun exposure.
Fortunately most of the danger is confined to the siding or other objects that are in the way of the pressurized spray.

The good news is you can clean your siding and roofing to look just as nice as the day they were installed.
I d say this happens on around 10 of my siding cleanings depending on the level of experience of the guy doing the rinsing.
