About that scheduling.....In the marketing it says that surfaces stay clean for three to five yrs...,does this just apply to shingle roofs? What i am trying to understand is that if they normally have to pressure wash twice for the year and i ofter softwash once a year at a price 30% percent more than pw, then what's the point in them giving me the job. I was selling it on the fact that it last 4 too 5 times longer...
I am confused.
