Home›Roof Cleaning & Moss Removal›Merrow
Green cushions on the back slope, crusty lichen freckling the ridge, a roof gone almost black with algae – Merrow roofs get scraped clean by hand, finished with steam or a soft rinse matched to the tiles, and the gutters emptied before we go.
Left alone, roof moss behaves like a wet bath mat draped over your tiles. It keeps the surface damp for weeks, creeps under the bottom edge of each course, nudges tiles upwards as it thickens, and every so often lets go in clumps that land straight in the gutter. Winter after winter, the trapped water freezes and expands, and the face of clay and concrete tiles slowly spalls away. Booking roof cleaning in Merrow breaks that pattern and makes the house look years younger from the road.
The first stage is always manual moss removal. Our tile scrapers are made to measure for the profiles found locally, so they slide between courses and peel growth off without prising or snapping anything. Next comes the finishing clean, and the tiles decide which: roof steam cleaning for softer or older coverings, or a low-pressure wash for sturdy modern tiles, either of which shifts leftover algae, lichen crusts and grime. For a longer-lasting finish, a biocidal treatment goes on afterwards to discourage fresh growth for longer. Finally, because scraped moss inevitably finds its way into the guttering, each gutter is emptied, each downpipe checked, and the paths and borders swept.
Moss needs three things – shade, damp and shelter from drying winds – and the lower slopes of the North Downs give Merrow plenty of each. Houses climbing towards Merrow Downs, and those around Merrow Woods and Boxgrove, are often hemmed in by tall beech, oak and yew. A rear roof slope there can go from a sprinkling of green to deep, spongy mounds within a few years, while the sunny front looks almost untouched.
What sits on the roof varies with the age of the house. Interwar properties strung along Epsom Road and gathered near St John’s Church commonly wear plain clay tiles, which harbour lichen and let moss root into the narrow gaps between courses. Bushy Hill and the post-war roads nearby are mostly concrete interlocking tiles, with a coarse face that gives algae and moss an easy grip. Larger homes up by Guildford Golf Club add dormers, hips and valleys where wind-blown debris gathers and moss gets a head start. Scraping, steaming or rinsing is chosen roof by roof, never by habit.
We clean and de-moss roofs right across Merrow’s GU1 and GU4 postcodes. A quick self-check: go into the back garden and look at the slope you rarely see. If that side is furred with green and the gutters keep filling with little moss pellets, the roof is ready for attention.
Because tiles differ so much, we decide the method after looking at your roof, not before.
We work out what the covering is, roughly how old, how sound the tiles look and how deep the growth goes. Those answers settle whether steam or a soft rinse follows the scraping.
Fitted scrapers peel moss from each row in turn. Loose growth is bagged or brushed down as the work progresses, keeping it out of the garden and away from the downpipes.
Remaining algae, lichen crusts and grime are lifted with roof steam or a low-pressure rinse. We keep the flow gentle so ridge mortar, lead flashing and tile faces come through unharmed.
An optional biocidal coat goes on to discourage fresh growth. The guttering is then emptied of the inevitable moss crumbs, downpipes are tested and the ground is swept clean.

A soft old clay tile and a hard modern concrete one do not want the same treatment. Around Merrow we regularly work on:
Before anything starts, we tell you which approach your roof is getting and why, so there are no surprises.
No two roofs are alike, so each gets its own quote. These are the details that move it:
Pictures of the roof from the back garden and from the road usually give us enough to fix a figure.
Yes, provided the method respects the tile. Many 1920s and 1930s Merrow homes have softer clay coverings, so we rely on hand scraping followed by steam or a very gentle rinse. Aggressive high-pressure jetting, which can strip the fired surface, is something we avoid entirely.
Usually it is the slope facing north or the one shaded by trees from the Downs or next door’s garden. It stays damp after rain and rarely sees direct sun, which is perfect for moss. The opposite slope dries quickly in the wind and sunshine, so growth struggles there.
It varies with shade, overhanging branches and whether the biocidal coat was added. Treated roofs keep moss, algae and lichen away for noticeably longer, because the treatment discourages spores from settling. A roof under heavy tree cover will always regrow sooner than an open, sunny one.
No – emptying them is part of the job. Scraping always sends crumbs of moss into the gutter, so once the roof is done we clear every run and test the downpipes. Otherwise the next storm would simply wash it all into the outlets and block them.
Normally, yes. We plan our access so no weight goes on glass or a lightweight flat roof, and we cover or shield what is below to catch falling debris. Plenty of Merrow houses have rear extensions or conservatories, so this is a familiar set-up for us.
Steam uses heat to soften stubborn lichen and grime at very low pressure, which suits older or more delicate tiles. A low-pressure rinse with cold water is ideal for washing loosened growth off tougher concrete tiles. We choose after seeing your roof and explain the reasoning.
