Roof Cleaning in Stockton-on-Tees: common questions

How much does roof cleaning cost in Stockton-on-Tees?

For a typical semi, a moss scrape and biocide treatment usually runs £400 to £800. Soft washing a larger detached roof can reach £1,200 or more. Be suspicious of very cheap quotes, they often mean a quick blast with a pressure washer and no treatment, so the moss is back within a year.

Is pressure washing safe for roof tiles?

It's contested. High-pressure washing can strip the granular surface from concrete tiles, force water under the laps and shorten the roof's life. The safer standard is manual moss removal followed by a biocide or soft-wash treatment. If a company leads with pressure washing alone, ask hard questions.

How long does a roof clean last?

A proper scrape plus biocide treatment typically keeps moss at bay for three to five years. The treatment keeps working for months after application, so roofs often look better six months on than they did on the day.
