Damp conditions encourage moss and algae to spread across roof tiles, and once established it can hold moisture against the surface. A roof cleaner uses a softwash treatment to deal with this at the root rather than just blasting the surface clean, which tends to give more lasting results.
Expect £400 to £1,000 per job, roughly £8.50 to £14 per square metre, depending on the size of the roof and how straightforward access is. A single storey property is usually quicker and cheaper to treat than a taller one.
