Metal Roof

[Kory]

I am cleaning a restaurant roof that is panted metal. Roof has bird crap, pollin, fall out and minor grease. I plan on going with clorine & shooting it from the ground with a soap nozzle ( Shoots 20-25 Feet) then spray it clean.
If anyone has any suggestions or have done this and can give any advice I would appreciate it. I use a skid unit 3500 psi 8 gpm hot water if that helps.

I would not use a strong chlorine mix.It will prematurely rust the screws holding the panels down ands cause fading of the color.

I have used a truck soap mix on metal roofs. Keep it diluted and throw in some wax and they turn out nice.
