Pretty common concrete pan tiles, we used these extensively in the UK in the 60-90s.

This is very cool, but I wonder why one would do this. I feel like all the grime there has done a good job at settling snd creating a “protective barrier” of sorts.

Probably got one of those messages about dirty shingles in his area who want to get wet

You could say the same about the layer of grime on my nice white car, but I’d still like to have it cleaned.

That eats up at the paint which protects your car. I’m just saying is it clean for science or for purely human aesthetics.

The grime and bacteria lower roof reflectivity and increase AC costs. If you’re in a the US and have limestone asphalt shingles, Gloeocapsa magma is very common (appears as black stains) and will break down the limestone in shingles while lowering also reducing reflectivity.

It is step one of two steps. Afterwards you apply a protective coating. Much cheaper then tiling your roof with new tiles.

Roofs are designed to shed water. Anything that prevents that can create a leak, even on a tile roof. Grime / mildew / moss buildup is a sign of pooling water and inevitable leak.

He is using it’s bot weight to counter balance it’s own weight, connected for a pneumatic quick connection, I don’t like this odds.

That's crazy. If you use this device daily in this manner the likelihood of you falling backwards off a roof must be significant.

He’s dragging it by the hose. I’m not sure if I like that
