Free gutter clearance and free biocide on every Highnam roof clean. Ageing Maidenhall and Oakridge tile, and heritage roofs near the Court, handled correctly.
Highnam sits on low, flat ground three miles west of Gloucester, pinned between the River Severn on its Gloucester side and the River Leadon to the north, with Alney Island and the floodplain just across the water. It's the kind of geography that holds damp. The vale floods — the Severn put a lot of this low ground under water in both 1947 and 2007 — and even in a dry summer that flat, wet basin keeps the air sitting heavy with moisture. Moisture is exactly what moss, lichen and gloeocapsa algae feed on, so a Highnam roof tends to carry more growth than an identical house up on the drier slopes towards the A40 or out past Newent.
Then there's the tree cover, which is what really sets Highnam apart. The village is ringed by woodland — RSPB Highnam Woods on the western edge and Lassington Wood to the east — and the parish is dotted with mature trees and hedgerow. All that canopy throws shade across roofs that would otherwise dry out in the sun, and every autumn it drops a steady fall of leaves and debris onto the tiles and into the gutters. Shade keeps a pitch permanently damp; leaf-litter feeds the moss and clogs the drainage. North-facing slopes under the tree line are usually the worst, going green years before the south-facing side of the same house.
Most of the village's housing is the kind of roof that suffers most in those conditions: concrete interlocking tile. Maidenhall — the core estate, started in the late 1930s and built out through the 1940s, 50s and into the 60s — and the 1970s Oakridge ring are mostly textured concrete tile, and textured tile gives spores something to grip. By the time someone calls us, a north-facing Maidenhall roof is often a thick mat of moss sitting in the laps, with the gutters behind it choked with washed-down growth and leaf-mould off the surrounding trees.
One thing that's specific to Highnam is how tightly the estates were built within a few years of each other. Maidenhall went up across the same post-war decades, and Oakridge a little later, so a whole road of roofs reaches the point where the 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 that's already several decades old: the surface coating has thinned with age, and hammering it with high pressure takes years off the tile to buy you one clean season. Lifting the moss by hand and then treating with biocide is gentler on the tile and lasts far longer, which matters when the roof still has plenty of life left in it.
Each one has its own approach. Method matters more than equipment.
The bulk of the village. Maidenhall was built across the late 1940s, 50s and 60s, so much of its Marley and Redland concrete tile is now decades old — textured, moss-gripping, and with a surface coating that has thinned with age. We lift the moss off by hand, then biocide. No high pressure on tile this old. Expect a noticeable colour shift as the treatment cures over a few weeks.
The Oakridge loop and the streets around it are a little younger but the same textured concrete tile, and the same heavy north-facing growth under the village tree cover. Standard bulk-removal-then-biocide treatment, with the gutters pulled through at the same time — they fill fast here with leaf-mould off the surrounding woodland.
Brimsome Meadow, Poppy Field and the other newer pockets named after the old farmland — smoother, younger concrete tile from the more recent builds. Younger doesn't mean immune: in this damp, shaded basin even fresh tile greens on the north side. These take bulk-off-then-biocide, and on the right surfaces a sealant to slow regrowth.
The older properties around Highnam Court, Church Lane and the farmhouses out towards Lassington and Over — hand-made clay, stone and slate, often a century or more old and brittle when wet. These are scraped by hand, never pressured, working off a roof ladder, with everything kept clear of lime mortar and old leadwork.
From the post-war Maidenhall core to the newer field-named closes and the hamlets in the parish — same Severn-Leadon damp, slightly different roof on each.
The village's core estate, started in the late 1930s and built out into the 1960s — almost all concrete interlocking tile, much of it now well into its second life and carrying heavy moss on the shaded, north-facing pitches.
The 1970s ring of housing wrapped around the village, with its all-weather footpath loop — settled streets of textured concrete tile that mat up fast under the surrounding tree cover and damp basin air.
The newer developments named after the original farmland — Brimsome Meadow, Poppy Field, Stoney Field, Long Field and the rest — younger, smoother tile that's still greening on the north side, so worth treating before the moss takes proper hold.
The older heart of the village around the green and the lane up to Holy Innocents Church and Highnam Court — a mix of period cottages and heritage clay, stone and slate that gets careful hand-scraping rather than pressure.
The hamlet to the east of the village, beside Lassington Wood — scattered houses and farmhouses under heavy tree cover, where shade and leaf-fall keep roofs damp and gutters blocked most of the year.
The hamlet on the Gloucester side of the parish by Telford's Over Bridge and the A40 gateway, close to the Severn and Alney Island — low, damp ground that grows roof moss readily, on a mix of older and modern tile.
Most of Highnam is post-war and modern estate tile, but the village has a remarkable heritage core, and the roofs there need a completely different hand. Highnam Court is a Grade I house with origins in the seventeenth century, set in Grade I registered gardens that Thomas Gambier Parry laid out after he bought the estate in 1837 — including one of the country's earliest pinetums — now opened to the public. Around it stands a cluster of estate buildings Parry put up: the church, the lodge, the rectory and the old schoolhouse, several of them listed in their own right.
The jewel is Holy Innocents Church. Built between 1849 and 1851 to Henry Woodyer's Gothic Revival design as Parry's memorial to his first wife and the children he lost young, it carries an interior frescoed by Parry himself in his own "spirit fresco" technique, and John Betjeman called it "the most complete Victorian church in this country." It is Grade I listed. We're not roofing contractors and we don't touch the church — but it tells you the kind of fabric that turns up on the older properties nearby: old clay, stone and slate on structures that have stayed watertight for well over a century by being left alone, not blasted.
On any heritage roof in the village we hand-scrape only, never pressure, because force cracks old tile and drives water into a structure that has earned the right to be treated gently. For listed buildings, cleaning sits in a careful zone: straightforward removal of biological growth normally doesn't need listed-building consent, because you're not altering the fabric, but anything that touches mortar, lead or the original tile-fixing usually does. We'll tell you upfront if a job crosses that line so you can speak to Forest of Dean District Council's conservation team before booking. We keep biocide off lime mortar by sheeting and rinsing the edges, and where old lead has weathered to a soft grey patina we'll usually recommend leaving it rather than scrubbing it back to bright metal — which is exactly the kind of thing heritage officers, reasonably, don't want to see.
At quote stage we check whether your property looks listed and glance at the Historic England map before the survey. It costs us five minutes and can save you a planning headache.
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 the older properties near the Court and church we flag anything that touches listed-building rules first.
Heavy moss is removed by hand from a ladder or tower, gutters cleared at the same time. On Highnam's damp, thickly mossed concrete tile — and on fragile heritage clay alike — the bulk growth has to be lifted off before the biocide can reach the spores beneath, and the leaf-litter off the surrounding woods comes out of the gutters with it.
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 shaded, high-humidity river basin 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.
A Highnam 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 basin this damp and tree-shaded. You pay for neither; both come as standard.
The free gutter clear is more than a nicety here. Highnam is ringed by woodland, and every autumn that canopy drops leaves and debris straight into the gutters; add the moss that washes down off the roof and a gutter blocks quickly, pushing water down the wall instead of away from the house — which matters on low ground that already deals with plenty of water. 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 Highnam customers get two seasons or more before they'd even think about booking us back — in a microclimate this damp, that's the part that earns its keep.
Get my Highnam quoteHighnam runs from big, mossy concrete-tile semis and detached homes on Maidenhall and Oakridge through to the occasional brittle heritage roof near the Court — and the fragile ones take careful hand-scraping rather than fast pressure, 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 semi or detached 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.

Highnam sits in a low, damp basin between the Severn and the Leadon, three miles west of Gloucester, with RSPB Highnam Woods on one side and Lassington Wood on the other. Low ground keeps the air humid, the surrounding woodland throws shade and sheds leaves onto the roofs every autumn, and the heavy tree cover keeps north-facing pitches from ever properly drying out. Humidity, shade and leaf-fall are exactly what moss, lichen and algae feed on, so a Highnam roof tends to carry heavier growth than a house on the open, drier ground up towards the A40 or out past Newent.
No. The textured concrete interlocking tile on Maidenhall and Oakridge — much of it now several decades old — has a surface coating that thins with age, so we don't hammer it with high pressure. We lift the moss off by hand from a ladder or tower, then treat with biocide. That's gentler on tile that still has plenty of life left, and the biocide is what actually stops the moss returning, not the force of the water.
Up to two years, often longer, because the biocide carries on killing fresh spores after we've left. Highnam is a damp, tree-shaded village in a river basin, so it sits at the wetter end of the county and north-facing pitches under the woodland canopy may colour up sooner than open south-facing ones. 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. Highnam backs onto Severn and Leadon floodplain and two woodland nature reserves, so we're particularly careful about run-off, and we've never had an issue with ponds or wildlife in years of doing this.
Possibly. Highnam Court is a Grade I 17th-century house with Grade I listed gardens, and Holy Innocents Church — Henry Woodyer's 1849–51 Gothic Revival church, which Betjeman called the most complete Victorian church in the country — is also Grade I, along with the cluster of estate buildings Thomas Gambier Parry put up around it. Roofs on or near those have old clay, stone or slate on fragile structures, and on those we hand-scrape only, never pressure, and keep biocide off lime mortar and old leadwork. Straightforward moss removal usually doesn't need listed-building consent because you're not altering the fabric; anything touching mortar, lead or the original fixings does, and we'll flag it before we start so you can check with Forest of Dean District Council first.
It does. Highnam sits on low ground between the Severn and the Leadon, with Alney Island and the floodplain on its Gloucester side — the same Severn that flooded badly across the vale in 1947 and 2007. Even in a dry year that low, wet ground keeps humidity high, and high humidity is what moss, lichen and algae live on. Add the shade and leaf-fall from Highnam Woods and Lassington Wood and you have a microclimate that grows roof moss fast. It doesn't change how we clean, but it does mean the free biocide treatment earns its keep here.
For most 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 standard two-storey semis and detached homes across Maidenhall and Oakridge that's usually all it takes. On steeper or older roofs — including the heritage clay and stone around the Court and church — 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 and why.
Three reasons that matter, in order. Tile life — moss holds moisture against the surface, accelerating freeze-thaw damage and shortening the life of the roof, which on an ageing Maidenhall concrete tile brings forward an expensive re-roof. Gutters and downpipes — moss and leaf-litter off the surrounding woodland wash into the gutters and block them, pushing water down the wall instead of away from the house, which matters on low-lying ground that already deals with plenty of water. Insurance and resale — some insurers query roofs visibly covered in growth, and a clean roof is a quiet but real factor in kerb appeal in a sought-after village like Highnam. Cleaning costs a fraction of replacing tiles or repointing ridges.
No roof stays clear forever — spores are always airborne, and in a tree-ringed, damp village like Highnam 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, on the right surfaces, a sealant) is the longest-lasting answer.
Depends on the tile, and in Highnam the honest answer is usually no. Most village roofs are ageing concrete interlocking tile on Maidenhall and Oakridge whose surface coating has thinned with age — blasting it with high pressure strips the tile and buys you one season. The old clay, stone and slate on the heritage buildings around the Court and church should never be pressure-washed at all. On both we lift the moss by hand and treat with biocide. 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.
