Moss thrives on shaded, damp roof slopes, and once it's established it can hold water against tiles long after the rest of the roof has dried out. A roof cleaner covering Sandy will usually assess this before recommending either a softwash or a more thorough moss removal, depending on how far the growth has spread and how exposed the affected slopes are to shade.
Roof cleaners quoting for Sandy jobs typically also serve Luton, Flitwick, Kempston and Henlow, which can be useful if you're comparing prices with a neighbour or friend living in one of those towns.
Ask each roof cleaner whether their quote covers a full steam clean or a manual scrape and treatment, since this changes both price and how long the results last before moss starts to return. Neither approach is wrong, but the price and finish can differ quite a bit.
Bark's data suggests a typical job costs between £400 and £1,000, roughly £8.50 to £14 per square metre. The exact figure depends on roof size, access, and whether it's a manual scrape and biocide treatment or a full steam clean.
