I'm afraid that in my location by the time the roof pays off, the roof will be so badly polluted with pollen, moss, and residue from air pollution applied by the rain, that the fall in efficiency will render the entire system inoperable.

- expertentipp 3y agoDepends from the flora in the region. Once lived in a city district with trees producing sticky syrup (maple?) and yellow powder (birch?). This mixture was penetrating every aperture in e.g. a car. Went to car wash, the next day car was sticky again. Spruce and pine pollen result in a moss-like layer on the roof quite quickly.
