Softwash Ranger was contracted to clean the roof of a well known chain restaurant. The roof was a Duro last membrane roof. The roof was dirty and greasy from the environment and mostly from the grease from the kitchen duct work. The company that cleans the ducts and grease traps cleans them on the roof but does not clean up after themselves. They have left a couple of years worth of grease on the roof membrane. We saw this as an opportunity to show the power of softwashing . We used a 2 percent mix with plenty of green wash and Terra wash in it And some elbow grease. We were able to give them a clean roof and we are looking forward to doing more work for them.
