Older housing stock combined with Kent's damp climate means moss and black algae streaks are common on roofs around Rochester. Left untreated, moss can lift tiles and hold moisture against the roof structure, so a roof cleaner will typically look at the extent of growth before recommending a treatment plan.
Most roof cleaners will apply a softwash treatment as standard, reserving manual scraping for patches of thick, established moss that a chemical treatment alone won't shift. This keeps costs down and reduces the risk of dislodging tiles.
Since roof cleaners covering Rochester often also work in Chatham, Strood, New Romney and Longfield, it's worth getting a few quotes to compare pricing and approach. Bark lets you post your job once and hear back from several local professionals.
Bark's data suggests a roof clean in Rochester runs from £400 to £1,000 per job, around £8.50 to £14 per square metre, with the exact price depending on roof size, access, and whether it's a manual scrape and biocide treatment or a full steam clean.
