Scraping moss off roofs is something we have done a lot of.
On this job we were working all the way along a mossy church roof wire brushing all of the moss off (and after that was done it was all cleared out of the gutters, bagged, and taken off site).
This job was the same – a very heavily mossed roof that needed cleaned down.
Looking along the roof – you can clearly see the moss.
This pictures shows the cleaned versus the not yet cleaned parts of the pitch.
Another shot that shows cleaned areas and non cleaned.
Looking back along the pitches after they had been fully cleaned all the way along.
Piles of removed moss at the bottom of one of the pitches. This was all bagged and taken away.
