Roof has rough cast concrete tiles I bet. The wavy Marley Modern ones seem the worst for moss growth.
Kill the moss which causes the problem on the north side mostly with Tide washing powder in punctured plastic bags catapulted or poked up with a long pole to the ridge tiles. They will slowly leach out the bio-detergent and bleach which will kill the moss if you get them a couple of feet apart along the top of the roof.
Galvanised chicken wire rolls in the gutters will keep the leaves out for a while.
You can get long poles with a bend on the end that you can couple to a hose or power washer to wash out the gutters from ground level.
