A little help on a metal roof

What would you guys use to get this metal roof clean? Really interested in the area under the tree.


A little hypo with a little extra surfactant.

A bucket truck or lift.

A high volume rinse machine.

Low pressure of course.

Yep, what Tim said. I cleaned one metal roof just like that except I didn’t need the bucket truck. It worked fine.

Rinse, rinse, rinse and then rinse some more.
