Roof moss removal in Teesside

What proper moss removal looks like

Done properly, moss removal is a hands-on job, not a jet wash. The bulk growth is removed by hand using profiled scrapers matched to your tile shape, working down the roof so nothing is forced under the laps. What the scraper leaves, the spores and root threads invisible from the ground, is killed with a biocide treatment that keeps working for months. Gutters are cleared of everything the roof sheds, and every bag of moss leaves the site with the team.

The result is not just cosmetic. Moss holds moisture against the tile face, and on Teesside's freeze-thaw winters that moisture is what spalls and cracks tiles. Removing it properly adds years to the covering, clearing it wrongly (pressure washer, wire brush on a pole) takes years off.

How established is yours?

Light growth: scattered clumps on the north slope, green film elsewhere, a straightforward scrape and treat, bottom of the price range. Established growth: moss cushions across multiple slopes, lichen colonies, gutters already blocking, a longer day and more biocide, middle of the range. Neglected: moss thick enough to lift tiles, downpipes overflowing, the survey will also check for tiles already damaged by the growth itself, and quote any replacements separately and visibly.

What happens on the day

Access equipment goes up first, roof ladders and harnesses as standard, towers where the roof needs them. The scrape takes most of the day on a semi. Biocide is sprayed once the bulk is off, and the team clears gutters and tidies before leaving. You do not need to be home, just outside access and a tap.

Keeping it off

Biocide keeps working after the team leaves, typically two to four years of clear roof on an open plot, less under heavy tree cover. Some owners book a biocide retreatment every few years as cheap prevention; others add sealing to slow regrowth further. The moss removal guide covers the whole decision.
