Power Washing and Roof Cleaning Forum

The Roof Wizard was contracted to clean this Marriot in Hanover/Whippany, NJ, this past week. The project was a challenge with the hotel being extremely busy and booked out solid every day. The building ranges from 8-11 stories and only a lift could be used on one and half sides. All the other sides are surrounded by the 20,000/SF conference center, which also was booked solid. We softwashed the entire building Monday, Tuesday & Wednesday which put us a day ahead of schedule. The hardest part was dealing with the extreme wind, rain and 48 degree weather on Wednesday. The surface was a Siloxane coated EFIS, which was infested on two sides pretty bad. The hotel management had two other quotes from local pressure washers, who said the project would take a minimum of six days, and they could not assure them that the coating would not be damaged.
