Roof cleaning in Cheltenham: a low-pressure clean or a manual moss scrape, finished with a biocide treatment. Most roof cleans are £550–£950, including a free gutter clear and a 2-year moss-free guarantee.
Free gutter clearance and free biocide on every Cheltenham roof clean. Conservation-area work handled correctly.
Cheltenham sits in a basin with the Cotswold escarpment to the north and east, and the prevailing south-westerly weather pushes damp Severn-valley air up against Cleeve Hill. The result, for a roof, is a microclimate that holds moisture for longer than open ground a few miles east. Add to that the town's mature tree cover — Pittville Park, the Promenade chestnuts, Lansdown's wooded plots — and you get north-facing pitches that barely see direct sun from October to April. That's prime conditions for moss, lichen and gloeocapsa algae to colonise tiles.
You see this most clearly on the Regency villas around Montpellier and Lansdown. Welsh slate roofs that look black at street level are often a quarter-inch of green moss between the courses by the time someone calls us. The slates underneath are usually fine — Welsh slate is the most durable roofing material ever made — but the moss has been holding water against the laps for a decade, and the lead flashings around the chimneys have started weeping rust stains down the gable. None of that is structural; all of it is fixable with a careful clean and biocide treatment.
The post-war stock — Charlton Kings, Hatherley, Up Hatherley, Benhall — is mostly concrete interlocking tile with the occasional plain clay roof on older streets. These respond well to our hand-scrape and biocide method too, but they often come with thicker moss because the tiles are textured, which gives the spores more to grip. We deal with the bulk by hand from a tower or roof ladder before the biocide goes on. The same picture extends north to Tewkesbury and east to Pershore — same Severn Vale moisture, same post-war estate stock, same approach.
Each one has its own approach. Method matters more than equipment.
Common around Montpellier, Lansdown, Tivoli, Park. Slates last a century or more; the issue is moss in the laps and rust running off lead flashings. Method: hand-clear the laps, low-pressure rinse, biocide. Slate gets the gentlest end of our toolkit.
Found in Prestbury, Charlton Kings, Battledown, Cleeve Hill. Beautiful but porous. Stone tiles get hand-scrape and a neutral biocide rather than pressure — pitting is irreversible. There's no shortcut here.
The bulk of Hatherley, Up Hatherley, Benhall, Warden Hill. Marley/Redland tiles, often heavily mossed because the texture grips spores. Manual moss removal by hand first, then biocide. Expect a noticeable colour shift after biocide cures over a few weeks.
Older streets near the town centre and parts of Pittville. Brittle when wet — we don't walk these without a roof ladder hooked over the ridge. Hand-scrape and biocide, with extra care around hipped junctions and valleys where tiles are bedded.
Large parts of central Cheltenham sit inside conservation areas, and a meaningful number of properties around the Promenade, Imperial Square, Suffolks and Pittville are Grade II listed. For listed buildings, "cleaning" sits in a slightly grey zone — straightforward cleaning of biological growth normally doesn't need listed-building consent, because you're not altering the fabric of the building. Anything that touches mortar, lead, or original slate-fixing methods does need consent, and we'll tell you upfront if a job crosses that line so you can speak to Cheltenham Borough Council before booking.
In conservation areas without listed status, the practical issue is method rather than permission. We don't use sodium hypochlorite at concentrations that strip patina, and we keep biocide off lime mortar by sheeting and rinsing edges. On a Regency property where the lead flashings are original, we'll often recommend leaving the lead alone and letting it weather rather than scrubbing it back to bright metal — patina is part of the look, and aggressive cleaning of lead is something the heritage officers reasonably get twitchy about.
Quote-stage we'll always note if your property looks listed in the title, and we'll check the Historic England map before the survey. It costs us five minutes; it can save you a planning headache.
From Regency slate in the conservation areas to post-war concrete tile on the estates — same basin damp, a different roof in each. Same pricing across the town, no extra travel charge.
Regency and early Victorian villas and terraces around Pittville Park, much of it in a conservation area. Mostly Welsh slate, often on shallow pitches behind parapets, so access is by tower and roof ladder and the method is hand-clearing and a low-pressure rinse at most.
An old village core of Cotswold stone and clay around the church and High Street, ringed by inter-war and post-war semis in concrete tile. The stone roofs get a hand scrape only; the newer tile can take a low-pressure clean.
Victorian villas in Welsh slate alongside large post-war estates in concrete interlocking tile, with mature trees on many plots. Shaded north-facing pitches here are usually the ones carrying the heaviest moss.
Victorian and Edwardian houses in slate and clay below Leckhampton Hill, with inter-war and later semis further out. Tree cover off the hill keeps a lot of these roofs damp through the winter.
Mostly estate housing from the 1970s onwards, almost all concrete interlocking tile. Straightforward access in most cases, but the textured tiles hold thick moss once it takes hold.
Inter-war and post-war semis and bungalows, largely concrete interlocking tile with some older clay. Mostly ladder or tower work from the front, with gutters cleared on the same visit.
Post-war housing from the 1950s onwards, mostly semis and terraces in concrete tile. Long runs of terraced roofs are cleaned from a tower or ladder rather than by walking the tiles.
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.
Heavy moss is removed by hand from a ladder or tower, gutters cleared at the same time. On Cheltenham's thickly mossed concrete tile especially, 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.
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 Cheltenham 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. You pay for neither; both come as standard.
Get my Cheltenham quoteMost roof cleans in Cheltenham cost £550–£950, including moss removal, a biocide treatment and a free gutter clear. Larger, steeper or harder-to-reach roofs cost more. Cheltenham throws up more fragile slate and Cotswold-stone roofs than most of the county, and those take careful hand-scraping rather than fast pressure — which is part of why we won't quote a flat rate over the phone.
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.
How we quote: a free no-obligation survey, a written price the same day, no deposit, pay only when it's done. See our full roof cleaning cost guide → Also worth reading: is roof cleaning safe?, why clean your roof?, how to get rid of roof moss for good and the best time of year to clean a roof.
No. Welsh slate, Cotswold stone and old clay tiles get hand-scrape and biocide only — pressure on those will damage the surface. Modern interlocking concrete tiles can take a low-pressure clean where it's the right tool. The biocide is what stops the moss coming back, regardless of which method we use to remove the bulk.
Up to two years, often longer, because the biocide we apply keeps killing fresh spores after we've left site. Cheltenham's damp microclimate and mature tree cover do mean north-facing pitches in shaded plots may green up sooner than south-facing ones. Pressure-washing on its own gives you a clean roof for about a season — the moss is back the following autumn because the underlying spores are still on the tiles. A proper biocide treatment is the difference between scraping 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. We've never had an issue with garden ponds or wildlife in years of doing this.
For most jobs, no. We work from a ladder or scaffold tower with a long-reach lance, which means no concentrated weight loading on tiles and no boot scuffs on ridges. On steeper or more complex roofs — including a lot of the taller Regency town houses — we use a roof ladder hooked over the ridge to distribute 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 and slate life — moss holds moisture against the surface, accelerating freeze-thaw damage and shortening the working life of the roof, which on a Welsh slate Regency villa is a significant lifetime cost. Gutters and downpipes — moss sheds and washes into the gutters, blocking them and pushing water down the wall instead of away from the house, which on rendered or stone facades shows up fast. Insurance and resale — some insurers query roofs visibly covered in growth, and a clean roof is a quiet but real factor in kerb appeal when selling, especially in conservation areas where buyers are paying a premium for character. The cost of cleaning is a fraction of replacing tiles or repointing ridges.

Yes. On those roofs the method is what matters. Welsh slate gets the moss cleared from the laps by hand and, at most, a low-pressure rinse; Cotswold stone and old clay get a manual moss scrape only, never pressure. A low-pressure clean is kept for modern concrete tile where it's the right tool. Every roof finishes with a biocide treatment, we keep it off lime mortar, and we leave original lead flashings to weather rather than scrubbing them back. If you're unsure whether your house is listed, or what you can do to it, check with Cheltenham Borough Council's conservation officer before booking. We'll tell you at the survey which method we'd use and why.
No roof stays clear forever — spores are always airborne — but treating the cause keeps it clear for years not months: we scrape it off by hand or clean it away at low pressure, 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.
Spring (March–May) and early autumn are ideal — dry enough for the biocide to bond, and it sets the roof up before the damp months when moss grows fastest. We clean year-round, though; the biocide works whenever it's applied in dry conditions.
Depends on the tile. Modern interlocking concrete tiles can take a controlled low-pressure wash where it's the right tool; Welsh slate, Cotswold stone and old clay should never be pressure-washed — it strips the surface, cracks tiles and forces water underneath. On those we hand-scrape 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.

Really impressed with Aquapro Roof cleaning. Very professional guys that done such a good job, that it looks like I’ve had a new roof installed, (after 40yrs of dirt and moss). Blake talked me through everything in detail, and answered any questions I had. Showed me the end result with his drone footage and left house clean and tidy. Highly recommended.
