Chesapeake Hydro-Wash spent a day last week cleaning roofs in Middletown, DE.  Here's the pics from 2 of the houses that needed our non pressure chemical treatment.  We had a third roof scheduled but unfortunately we couldn't complete it because the windows were accidently left open.  We did manage to sign a neighbor up while we were there, so we will be back in Middletown next week to clean two more roofs.
