The first step in any successful roof repair is cleaning the roof. With a clean roof, whatever is done to fix the roof has a better chance of working as there is less to impede "stuff" from sticking. This works for whatever material is used. A clean surface (even if not doing roofs) is imperative to having a successful outcome.

This is my first piece of cleaning. It all pretty much was the same process. Started off by wetting the roof a little. As can be seen in the top photo, the end of the hose has a "firefighter type nozzle" in that can make a fine mist vs a steady stream. Unsure what it's called. Used this to make a fine mist and hung it from my hand so nozzle was couple inches from the roof top.

|Clean and dry, ready!|
The last picture shows just after prepped for painting, but shows the clean roof that is dry. Still looks like there's some dirt and stuff on there, and this is about a week after the cleaning. Am sure there is some dirt hiding in the crevices, but it still looked relatively clean.
