Yesterday we cleaned a 10,000 sqft metal roof in Clearwater Florida.

The home owner was amazed at how well it turned out & how quickly we were able to get it done.

I laid down our cleaning solution & set up 3 pressure washers around the house.To rinse it off. We did not use high pressure though what we did was set up a ball valve on the end of the hose to give us just enough pressure to rinse without causing tiger stripes.

That's the same way we rinse flat work after we clean it.

Looks like metal roof cleaning is back on our list.

The pictures don't show how dirty it was. I'll post the video later.It has more detail.
