I’ve done 4 one-story roofs and 1 two-story roof so I guess I’m a novice when it comes to that. I’ve never done a tile or brick roof though. I’ve been in business for 4 months with a few commercial contracts under my belt and tons of residential driveways and house washes. I’m not new to pressure cleaning because I had a business 5 years ago but shot it down due to me not having the proper knowledge to run it.
