Innsworth sits on the flat, low-lying ground on the northern edge of Gloucester, the old ex-RAF village now wrapped around by one of the biggest new garden communities in the county. It's a damp corner. The land barely rises, the brooks that thread through the area keep the ground wet underfoot, and Innsworth holds the distinction of being the largest community inside the Gloucester and Cheltenham Green Belt — which in practice means leafy plots, mature hedgerows and open fields on every side. All that greenery is lovely to live among, but it pumps moss and algae spores into the air and keeps roofs shaded and slow to dry. A roof here will carry more growth than an identical house up on the drier slopes towards Churchdown or the Cotswold edge.
The thing that surprises people most about Innsworth is that the newest roofs aren't exempt. The garden-community estates off Innsworth Lane and Hanbury Road — Whittle Gardens and the rest of the Innsworth–Twigworth development — went up on modern concrete interlocking tile. That tile is textured, which gives airborne spores something to grip, and once a roof is roughly eight to twelve years old the north-facing pitch starts to show the first green-black streaks. Homeowners who've barely had the keys a decade are often startled to see it. In this damp, sheltered basin it comes on quicker than the brochure ever suggested.
Then there's the older Innsworth — the bird-named post-war estate built for the RAF station, with its Rookery Road, Bullfinch Way and the streets around them. A lot of that housing was thrown up fast after the war as prefab and 'no-fines' concrete homes, and those roofs have now had a long, hard life. The tile is more brittle, the ridge bedding older, and decades of damp have left some of them under a thick mat of moss. Different age, different tile, same Innsworth problem — and the same fix: lift the growth off gently, then treat the cause with biocide.
One thing that's very specific to Innsworth is how sharply the estates cluster by age. The post-war RAF housing went up across the same few years; the garden-community phases are going up close together now. So a whole close tends to reach the point where moss is impossible to ignore at roughly the same time — which is why, once we're booked on one house, we'll often end up doing two or three more on the same street that same week. It's also why we don't believe in pressure-blasting concrete tile, new or old. On a young estate roof high pressure can thin the factory coating and bring the green back faster; on an ageing RAF-estate roof it simply takes years off tile that's already near the end. Lifting the moss by hand and treating with biocide is gentler and lasts far longer — which matters whether your roof is forty years old or four.
Each one has its own approach. Method matters more than equipment.
The bulk of Whittle Gardens and the newer phases off Innsworth Lane and Hanbury Road. Modern Marley and Redland-type tile, only a few years old, with a factory colour coating you don't want to strip. We hand-lift any moss and soft-wash — never high pressure — so the coating stays intact and the green doesn't come back faster.
The bird-named streets — Rookery Road, Bullfinch Way and the closes around them — built quickly after the war, with a lot of prefab and 'no-fines' concrete homes. The tile and old ridge bedding are brittle now, so these get hand-scrape and soft-wash only, with extra care at the ridges, hips and valleys where the roof is most tired.
The semis and bungalows that filled in around the village from the sixties onward, towards Longlevens and Longford. Textured concrete tile that mats up heavily in this damp, shaded setting. We remove the moss by hand first, then biocide — expect a noticeable colour shift as the treatment cures over a few weeks.
Out on the village fringes towards Twigworth and Longford you still find older clay-tile cottages and farm buildings. Clay is durable but brittle when wet, so it gets hand-clearing of the laps, a low-pressure rinse and a neutral biocide, keeping everything off any old mortar and leadwork.
From the brand-new garden community to the old RAF estate and the cottages on the fringe — same damp, green-belt setting, slightly different roof on each.
The big new development off Hanbury Road and Innsworth Lane — well over a thousand homes on young concrete tile, with the first phases now reaching the age where the shaded pitches start to green.
Rookery Road, Bullfinch Way, Tern Court, Falcon Close and the streets around them — post-war housing built for the RAF station, much of it prefab or 'no-fines', with roofs that have had a long life and carry heavy moss.
The older spine of the village, around the church and the schools, where established semis and bungalows on sixties-to-eighties concrete tile mat up fast in the damp, sheltered air.
The military housing around Imjin Barracks, home of the Allied Rapid Reaction Corps since 2010 — uniform estate-type roofs that, like the civilian streets, green up together and benefit from the same gentle treatment.
The villages and ribbon housing just west towards the A38 — a mix of older clay-tile cottages and newer estate roofs, all sitting in the same low, damp ground that keeps moss coming back.
The edges where Innsworth runs into Longlevens and across towards Churchdown — established suburban streets on concrete tile, just far enough up off the wettest ground to green a little slower, but still greening.
Innsworth's story is unusual. It was farmland and a parish called Longlevens until the RAF arrived in 1940; the post-war years filled it with quickly-built housing for service families, and the parish was formally renamed Innsworth in 1967. The RAF moved out in 2008, the site became Imjin Barracks for the Allied Rapid Reaction Corps in 2010, and in the years since the Innsworth–Twigworth garden community has wrapped a vast new estate around the old village. The upshot is a place where you can stand on one street looking at brand-new concrete tile and, a few minutes' walk away, post-war prefab roofs that have weathered seventy-odd winters. Both green up — for the same reasons.
People often assume a new-build roof is somehow protected against moss. It isn't. The factory coating on modern interlocking tile slows water absorption, but it does nothing to stop airborne spores landing and taking hold — and the textured surface of estate tile actually gives them more to grip than smooth old slate would. Add Innsworth's damp, low-lying, tree-shaded position inside the green belt, and a roof that looked spotless on completion will usually show its first green streaks on the north pitch somewhere around eight to twelve years in. By the time a whole close was finished together, the whole close tends to need attention together.
The mistake we see most on new estates is someone reaching for a pressure washer, or hiring a firm that does. On young tile that's the worst thing you can do: high pressure thins or strips the very coating that's keeping the tile sound, so the roof not only ages prematurely but greens back faster afterwards, because the roughened surface holds even more moisture. The right approach on a new Innsworth roof is the gentle one — lift any moss by hand, soft-wash, and let an approved biocide kill the spores at the root so the result holds for years rather than a single season.
On the older RAF-estate and prefab-era roofs the logic is the same but the stakes are different. Those roofs are near the end of their natural life, so the goal is to clear the moss without taking years off what's left — again, hand-scrape and soft-wash, never pressure. Whichever side of Innsworth you're on, new tile or old, we survey the actual roof before we quote rather than guessing from the street.
We come out, look at the roof, the access and the gutters, and tell you exactly what's needed and what it costs. No hard sell, no pressure to book on the spot — and on a new garden-community roof we'll explain why soft-washing, not pressure, is the right call for young tile.
Heavy moss is removed by hand from a ladder or tower, gutters cleared at the same time. On Innsworth's damp, thickly mossed concrete tile — new estate and old RAF estate alike — the bulk growth has to be lifted off before the biocide can reach the spores beneath.
An approved biocide is applied at the correct dilution. It kills algae, lichen and remaining moss spores at the root, without high-pressure water touching the tiles — which matters even more in this damp, tree-shaded green-belt setting where regrowth comes back fast.
The biocide keeps working after we've left, preventing regrowth for up to two years. Most customers don't need us back for a top-up before then.
An Innsworth roof clean keeps us on the ladders or tower most of the day regardless, so it makes sense to pull the gutters through while we're up there — and the biocide is what holds the result for two years, which counts for a lot in a spot this damp. You pay for neither; both come as standard.
The free gutter clear is more than a nicety here. On the new garden-community estates the gutters are often choked with builders' grit and washed-down moss long before anyone thinks to look; on the older RAF-estate homes decades of growth have shed straight into them. Either way, a blocked gutter pushes rain down the wall instead of away from the house, soaking render and finding the eaves. We clear what comes off the roof as we go, so you're not left with a clean roof and blocked gutters. And because the biocide carries on working long after we've packed up, most Innsworth customers get two seasons or more before they'd even think about booking us back.
Get my Innsworth quoteInnsworth throws up everything from young interlocking tile on the garden-community estates to tired prefab-era roofs on the old RAF streets, and the careful soft-wash both need takes time rather than brute force — which is part of why we won't quote a flat rate over the phone. Every roof's different. But to be straight with you, most roof cleans are £550–£950. A standard terrace or semi sits in that range; larger, steeper or more difficult roofs (heavy moss, awkward access, big detached houses) go up from there.
What moves the price:
Always included, never an add-on: a free gutter clear while we're up there, and the biocide that keeps moss off for up to two years.

No — and on the newer estates it's exactly why method matters. The interlocking concrete tile on Whittle Gardens and the rest of the garden community is only a few years old, and the factory colour coating on the surface is the thing you don't want to strip. Blasting young tile with high pressure can thin that coating and actually make it green up faster afterwards. We lift any moss by hand and soft-wash, then let the biocide do the work. On the older bird-named RAF estate roofs and the prefab-era homes the same gentle approach protects tile that's already had a long life.
It catches a lot of people out. The garden-community estates off Innsworth Lane and Hanbury Road are surrounded by open fields, mature hedgerows and trees, and the whole area sits low and damp on the northern edge of Gloucester inside the green belt. Modern interlocking concrete tile is textured, so airborne moss and algae spores grip it easily, and once a roof is roughly eight to twelve years old it hits the point where growth on the shaded north pitch becomes obvious. A new estate doesn't escape moss — it just takes a few winters to show, and Innsworth's damp, sheltered setting brings it on quicker than higher, drier ground.
Up to two years, often longer, because the biocide we apply carries on killing fresh spores after we've left. Innsworth is a damp, low-lying, tree-shaded spot north of Gloucester, so roofs here green faster than on open higher ground — and north-facing pitches that get little sun colour up soonest. Pressure-washing on its own buys you about a season; the moss is back the next autumn because the spores are still in the tile. The biocide is the difference between cleaning the surface and treating the cause.
Yes, when applied properly. We use approved biocides at manufacturer-specified dilutions, applied in dry conditions so the active ingredient bonds to the tile rather than running off. Pets are kept indoors during application and for an hour after; planted borders are sheeted and watered down before and after. With so many Innsworth gardens backing onto fields, hedgerows and the brooks that run through the area, we're careful about run-off, and we've never had an issue with ponds or wildlife in years of doing this.
Yes — they're a big part of what we do in Innsworth. The Innsworth–Twigworth garden community is bringing well over a thousand new homes to the area off Innsworth Lane and Hanbury Road, and the first phases are now reaching the age where the original concrete tile starts to green on the shaded pitches. Whole closes were built at the same time, so a row of roofs tends to reach moss age together — which is why, once we're booked on one house, we'll often do two or three more on the same street that same week.
Yes, and these need a careful hand. The bird-named post-war estate — Rookery Road, Bullfinch Way and the streets around them — was built quickly after the war, with a lot of prefab and 'no-fines' concrete homes whose roofs have now had a long life. The tile and any old ridge bedding are more brittle than modern materials, so we hand-scrape and soft-wash rather than pressure-blast, and take extra care at the ridges, hips and valleys. The aim is to clear the moss and protect what's left of the roof's life, not take years off it.
For most Innsworth jobs, no. We work from a ladder or scaffold tower with a long-reach lance, which means no concentrated weight on the tiles and no boot scuffs on the ridges. On the newer two-storey houses on the garden-community estates, or the steeper older roofs, we use a roof ladder hooked over the ridge to spread the load safely. We'll tell you in advance which method we're using on your property and why.
Three reasons that matter, in order. Tile life — moss holds moisture against the surface, accelerating freeze-thaw damage and, on newer estate tile, thinning the protective coating, which shortens the life of a roof you probably haven't long paid for. Gutters and downpipes — moss sheds and washes into the gutters, blocking them and pushing water down the wall instead of away from the house. Kerb appeal and resale — on a tidy new estate a green-streaked roof stands out, and a clean roof is a quiet but real factor when you come to sell. Cleaning costs a fraction of replacing tiles or re-bedding ridges.
No roof stays clear forever — spores are always airborne, and in a damp, tree-shaded spot like Innsworth they're never far away — but treating the cause keeps it clear for years not months: we scrape or soft-wash the moss off, then apply a biocide that carries on killing spores for up to two years. Pressure-washing alone just removes what you can see — it's back next autumn. Biocide, plus a sealant on the right surfaces, is the longest-lasting answer.
On the modern tile across Innsworth, we'd usually advise against it. The concrete tile on the new estates is too young to risk stripping the factory coating, and the older RAF-estate and prefab-era tile is too far through its life to take the punishment. We soft-wash and hand-remove the moss instead, then treat with biocide — gentler on the tile and far longer-lasting. Where a sealant is the right call on a suitable surface, we'll say so. We always tell you the method first.

Blake and Daniel cleaned my patio and path at the front and did a great job. They were friendly and professional and explained well what they were going to do. I also had a bad dark patch which came up really well which others had failed to remove. I would definitely recommend them if like me you have a patio or driveway that badly needs a thorough clean

We had excellent service from start to finish. The guys were very professional, discussed everything over the phone initially then a visit with the drone to allow accurate quarter and expectation management. On the day they were considerate with the neighbours, did a wonderful job with the roof and gutters and cleared up so well that everything looked far better than when they started. Cannot recommend more highly.
