Wire brush, not jet wash.. we cover Winchester.

Yes this can be a problem if it's bad enough it will need removing. The best way is to scrape off and then spray with a moss prevention - I use a SKYVAC system, this saves the need for scaffolding in most cases.

Hi there, yes moss on any roof can most definitely be a problem as it acts like a sponge and soaks up water, adding weight to your roof and restricting the water flow down off your roof. I would have it scraped off and have moss prevention sprayed over your entire roof. It's not only the problems I mentioned above, but when moss does come off your roof, it blocks your guttering, restricting the rainwater from getting to your downpipes which is another problem. I did a roof in Edinburgh last year, we scraped the moss off the front and back of a 3 bedroom house and it filled 8 builders' waste bags full, the weight of which was incredible as the moss was full of water, which made it easier to scrape off. If the moss is dry then the weight is no issue but still a problem. I would get 3 quotes before you hire anyone, make sure they're going to hand scrape it off, clean your gutters and apply an antifungal prevention spray to your roof. Also, I might add if your roof is in an area that doesn't get much sun, moss removal would be something I would have done at least once a year. Good luck.

Hi yes, moss can be a problem if it’s built up for some time. It would need to be scraped or wire brushed off. Then I would put a strip of copper along the ridge to prevent it from coming back. You don’t need scaffolding as we do it on roof ladders hope this helps.
