Growth on roof
Discussion
For those that get growth on their roof - how often do you have it removed?
Talking some minor moss and the occasional grass / weed?
I presume it comes from bird droppings / on the wind.
We had it cleaned (not chemical just removed by hand / scraper) in march and we have had re-growth in the last couple of months.
Every house on the street seems to suffer from it. They are late 1800s.
The roof is very high so its not cheap to have done.

Fair amount of moss on my roof - has not changed in quantity in the 10 years I have been here, have not done anything with it, I just get the gutters cleaned a little more regularly. The only tile that came off in the last storm looked good and solid (and in bits).
I have had a few offers of people to come and jet wash it, spray loads on it etc - but if the quantity of moss is not increasing..

Lots of moss on my roof - i leave it be, can't do any harm can it? I wonder what the U value is
Neighbours (detached) had their roof pressure washed this year in the heatwave. I thought they were bonkers. Waste of water, money, and whilst it did look good I doubt it'll last long.
Depending on the tile type, jet washing makes them porous. Crazy thing to do imo.Neighbours (detached) had their roof pressure washed this year in the heatwave. I thought they were bonkers. Waste of water, money, and whilst it did look good I doubt it'll last long.
Unless the moss is literally blocking gutters or lifting slates leave it alone and ponder how lucky you are that your life is so free of care that you can invent things to worry about. The shower of snake oil vendors who want to jet wash, scrape or paint your roof should be invited to go forth and multiply.
We have quite a bit of moss and in the five years we have been here I don't think it's increased, but it's quite healthy looking.
Bungalow so gutter clearing is easier, but very frequent as the gutters fill after a heavy rain. I would like to remove it but don't want jet washing or walking on roof . The roof is very steep.

I pull out grass and small trees out of the gutters when removng acres of pine needles, typically every other year rather than annually, but the moss doesn't appear to do any harm.
Removed it once, manaually, back to full strength two years later. Were now on our 8th winter and it seems no worse than year 4,5 or 6.
