Home›Roof Cleaning & Moss Removal›St John’s
Between the canal mists and the shade of the oaks, roofs in St John’s can disappear under a green blanket. We scrape the moss off by hand, clean the tiles by the gentlest effective method and leave the gutters clear of every fallen clump.
A furry green roof might look quaint on a postcard, but up close the moss is quietly working against you. Each clump behaves like a bath sponge, holding the tile underneath damp for days, swells until it nudges the overlap upwards, and eventually tumbles into the gutter where it sets like papier-mache around the outlet. In a hard frost the water it traps expands, which is unkind to older tiles. Our roof cleaning St John’s service takes that growth off with care, and since the village has everything from century-old clay to modern concrete, we pick the technique to suit whichever tiles you actually have.
Hand scraping comes first on almost every job. The blades we use are shaped to the curve and nib of common tile profiles, so they slide along the courses and peel the moss away rather than prising anything up. After that the surface is either rinsed at low pressure or treated with roof steam, which uses heat to soften organic film and is the kinder option on fragile tiles. For owners who want the result to last, a biocidal solution can be misted over the clean slopes to hold back the next generation of moss, algae and lichen. The visit ends at gutter level, emptying every channel the fallen moss has landed in.
St John’s sits in a hollow of the Woking landscape where trees, water and heathland soils meet. The Basingstoke Canal runs through the village and along the flight of locks just outside the centre, and on still mornings the damp air lingers over the roofs nearest the water. Mature oaks around St John’s Lye and the pine woods on the slopes up to Hook Heath shade many roofs for much of the day, so they dry slowly after rain and stay cool, exactly the conditions moss and algae prefer.
Roofs here come in many forms. Victorian and Edwardian cottages in the older streets often wear handmade clay or Welsh slate, materials that call for a light touch, and some have valleys and dormers where debris and moss gather. Interwar and post-war homes commonly have concrete interlocking tiles, which can carry thick moss in their channels but tolerate a low-pressure wash well. The larger detached houses around Hook Heath tend to have big, complex roofs with multiple hips and valleys and plenty of overhanging trees.
Because of the shade and moisture, moss tends to return faster here than on an exposed roof, which is why many St John’s customers choose the biocide treatment after cleaning. It works gradually and helps keep the roof cleaner for longer. Our moss removal teams cover all of GU21 in and around St John’s, together with Knaphill, Goldsworth Park and Hook Heath next door.
We read the roof first; the tools come out afterwards.
Tile material, age and roof pitch are noted, any cracked or slipped tiles are photographed for you, and we explain the cleaning approach we think suits the roof best.
Shaped blades travel along each course by hand, lifting thick cushions from tile faces and joints while keeping water and grit from being pushed beneath the overlaps.
Leftover algae, lichen and thin green film are dealt with by roof steaming or a soft, low-pressure rinse, the choice depending on how old and delicate the tiles are.
If ordered, a biocide is misted over the slopes, then every gutter and downpipe is emptied of fallen moss and the paths, beds and lawn are cleaned up.

Some green is unavoidable in a village this leafy. It is worth booking a clean once you notice any of the following:
Any dry spell will do for the work, but late spring and early autumn are ideal, since tiles dry quickly and a biocide has weeks to act before winter. Unsure if yours has reached that point? Send a couple of pictures and you will get a straight answer.
Every roof gets its own figure once we have seen it, either on site or in decent photographs. We weigh up:
Pictures of the front and rear pitches, taken from ground level, are usually plenty for us to propose a technique and fix a price.
Over time it can. Cushions keep tiles constantly wet, nudge the overlaps apart as they swell and drop into gutters, where they cause blockages. Frost then works on that trapped moisture and can flake older tiles. Taking the moss off keeps the roof drier, the gutters clearer and the house looking cared for.
Moist air drifts off the Basingstoke Canal, and many nearby houses also sit beneath oaks and other mature trees. Between them, those two factors keep tiles cool and damp for long stretches, which moss loves. Applying a biocide once the roof is clean noticeably slows the comeback.
No. Moss is always scraped by hand to begin with, after which the tiles get whichever suits them better: steam or a soft rinse. Steam is particularly good for aged clay and slate, because it relies on heat to loosen growth rather than force.
Shade, nearby trees and whether a biocide was used all play a part. A sunny, open roof can stay clear for several years. Shaded roofs in St John’s may show a little fresh growth sooner, though the treatment holds it back considerably compared with an untreated roof.
We do, on every roof clean. Scraping sends a surprising amount of moss downwards, so each run is emptied and every downpipe tested before we pack the van. That clear-out is built into the price rather than charged as an extra.
Of course. Garages, sheds and garden rooms frequently have the worst moss on the whole plot, because they tend to sit under trees. They can be added to the same visit, with the technique adjusted for tiles, slate or felt as each one requires.
