Here is a Slate Tile Roof we did in the Avila section of  North Tampa using a Lift.
Slate Tile Roofs can not be walked on, if they are thin.
They require only shingle roof strength chemical unlike regular tile roofs. Surfactants can dull or cloud slate tile roofs, we did not use any on this North Tampa roof cleaning

This 10,000 Sq Ft Slate Tile Roof home in the Avila section of Tampa belongs to a Famous ex Baseball Player.
To respect his privacy, his name will not be revealed.
