Hello recently came about about a pretty big issue. I am in Central Cali, specifically Monterey County. As I’ve done many pressure washing and soft washing jobs, I’ve came to realize whenever I do any sort of Concrete Tile Roof shingles, they tend not to change color or clean at all! (Regular asphalt shingles clean just fine) I’ve only hit it with about a 5-6% mix to not cause a lot of damage to the surrounding plants.
I have a few things in mind I’d like to try.
- I will do a light brushing removing all loose and dry algae off the roof, then I will try and hit it with a soft wash.
- I’ve also seen many YouTube pressure washers say that LA’s totally awesome detergent works as an amazing roof cleaning surfactant. So I will be giving that a try.
Any pressure washers in Cali experiencing the same issue I’m facing? If so, how do you go about cleanings roofs without pressure? Thank you for reading!
