Howdy - just a quick question for anyone who has any experience with powerhosing a roof. I just got a call from my Dad there who had the roof of his house powerhosed to remove all the moss on it. The guys did a great job, only thing is water leaked into the kitchen, hall and one of the bedrooms. They said this was normal and it was no big deal. They said it wouldn't happen with rain, and that it was a result of the power of the hosing.
Is this normal?
