Moss growth and hopefully refresh what was originally a turf-brown appearance. The back of the house is not too bad because it faces SSW and gets the sun most of the day. Gutters and facias have been kept clean, but the roof has never been done in 35 yrs. I made contact with a guy today. He seems to have a fairly pro set-up. Initially want to get an idea of costs.What are you wishing to clean off the roof tiles specifically
Ok.... but ... what keeps so many of these guys in business, if it's strongly recommended against. The guy I've contacted can't come to look at the job till next week as he is too busy.Don't allow anyone to powerhose your roof, it causes a lot of damage and blasts gaps between tiles which will then leak, despite it being a very popular service any decent roofer will warn against it.
Re-pointed.The tiles going down the sides of the roof all had to be recemented (is that even a word!?)
That's the word I wanted lol thanks

Nothing exposed to the sun will retain its original colouring. I've never seen anyone recommend surface treatments like you see applied to driveways, likely because the slope means only a thin coat is possible and that would wear and look terrible pretty soon.Have I any options available to 'brighten up' the roof. (apart from renewing the tiles.)
Spray paint roof tiles - with the shade of original brown colourOk.. let's say we Brush/Scrape all the debris/moss from the tiles and then spray with one of the multitude of 'treatments ' available. I'm still left with
tiles that are nowhere near their original brown colour, in fact are almost black now. Have I any options available to 'brighten up' the roof. (apart from renewing the tiles.)
Painting would be difficult, expensive, and wouldn't last. They'd need to be very clean to ensure proper adhesion of a paint and then weathering and UV will attack and degrade it. Peeling paint after a couple of year would look far worse.Spray paint roof tiles - with the shade of original brown colour

heavy moss growth is best scraped off by hand, if you have overlapping tiles then the grove will need to be scraped clean as well.
Alternatively you could have it sprayed with moss killer, it'll die and fall off over time but they can clog gutters so these need to be kept clear.
