📞 Call Now: 0124 235 2251Cheltenham's tree-lined avenues, valley position and frequent rainfall create ideal moss growth conditions. The north-facing slopes of Regency terraces, Victorian suburbs and hillside properties in Leckhampton and Prestbury are the most affected. We treat the cause, not just the symptoms.
Professional-grade biocide applied by low-pressure spray. Kills moss, lichen and algae at the root. Moss dies back over 4–8 weeks and washes off naturally in rainfall. Lowest risk method for clay tiles and natural slate. Annual treatment from £150 for a standard semi.
Get a Quote →Where moss mat growth is already thick, biocide alone is insufficient. We use soft bristle brushes and low-pressure water to physically remove accumulated moss before applying biocide treatment. Safe for clay, concrete, slate and stone tile. From £250.
Get a Quote →Moss mat in valleys and gutters blocks drainage and backs water under tiles. We clear valleys completely as part of every moss treatment and include a gutter flush as standard. A valley blockage left until winter causes more damage than the moss treatment costs.
Get a Quote →Properties in high-growth zones — wooded boundaries in Prestbury and Leckhampton, north-facing Regency terraces, Severn Vale adjacent in Gloucester — benefit from annual scheduled treatment rather than reactive calls. Fixed annual pricing, scheduled each spring. Call us to set up.
Enquire →Lichen is harder to remove than moss and requires specialist biocide formulations. We treat lichen with appropriate products and physical removal where needed. Lichen removal is slower — full clearance takes 2-3 treatment cycles. From £200 for a standard semi.

Book Free Survey →Professional roof moss removal in Cheltenham costs £250–£700 for a typical semi, including scraping, biocide treatment and gutter clearance. Cheltenham's damp Severn Vale climate makes north-facing roofs particularly prone to moss. Free quotes and no call-out fee. Call 0124 235 2251 to arrange a survey.
Cheltenham's geography and tree coverage create a moss-friendly microclimate that is more aggressive than in many comparable towns.
Cheltenham's famous tree-lined avenues — Pittville, Montpellier, Bayshill — keep north-facing roofs in shade for long parts of the day, retaining moisture and providing the ideal moss growth environment. Properties on these streets need more frequent treatment.
Cheltenham sits at the foot of the Cotswold escarpment in a valley position that channels moisture from the west. Ambient humidity is higher than on the surrounding high ground, extending the damp periods that moss requires to grow.
Prestbury, Leckhampton Hill and the rural fringe properties have woodland boundaries that create persistent shade and leaf fall. Leaf matter in valleys and gutters extends moisture retention and provides organic matter that feeds moss growth.
Clay peg tiles, natural Welsh slate and Cotswold stone tiles on Cheltenham's older housing stock are significantly more porous and textured than modern concrete tiles. This texture provides better moss anchoring and higher moisture retention.
Cheltenham's damp, tree-shaded position makes it prime moss country, especially on north-facing slopes near the town's mature canopy. But moss is often a symptom, and how you remove it matters as much as whether you should.
When it is not the answer: If the tiles beneath the moss are sound, you need cleaning and treatment, not a new roof — and moss should never be pressure-washed, which strips the protective surface off tiles and shortens their life. Anyone jet-washing your roof is doing harm. Read the full guide.
We cover all of Cheltenham and a 15-mile radius across Gloucestershire. No call-out surcharge for any location within our service area. Call 0124 235 2251 to arrange a free survey.
We assess how heavy the growth is, check the tiles underneath for damage the moss may be hiding, and clear the valleys and gutters the moss has been feeding.
A fixed price for careful manual removal plus a biocide treatment, with any minor tile repairs found underneath quoted separately.
We pick a dry spell so the biocide can work; the job is usually a day or less.
We remove moss by hand and soft brush — never pressure-washing — then apply a biocide that continues killing spores for months. Zinc or copper strips can be fitted at the ridge to inhibit regrowth.
We bag and remove all the shed moss, clear the gutters and valleys it blocked, and leave the roof draining freely.
| Job | Typical duration |
|---|---|
| Moss removal (average house) | Half to 1 day |
| Removal + biocide treatment | 1 day |
| Add ridge zinc/copper strips | +2–3 hours |
| Heavy growth, large/steep roof | 1–2 days |
We treat in dry weather so the biocide isn't washed off before it works, and avoid removal in frost when tiles are most brittle.
Moss removal is worked from a roof ladder or tower on most Cheltenham houses; scaffold is only needed on steep or three-storey roofs. Scaffold is specified for: steep pitches, three-storey terraces, or where safe standing time is needed across a large roof - always itemised in your written quote, never a hidden extra, and we arrange it.
Cheltenham's Regency terraces in Montpellier and Lansdown have railings, lightwells and shared party walls that limit rear access, so pavement scaffold and skip space usually need a permit. Pavement scaffold and skip permits go through Cheltenham Borough Council; allow a few working days on streets like Montpellier Street, the Suffolks, the terraces off St Paul's Road where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Moss removal (average house) | £300–£600 | Manual soft removal |
| Removal + biocide treatment | £450–£800 | Long-acting spore treatment |
| Biocide treatment only | £250–£450 | Where growth is light |
| Ridge zinc/copper strips | £150–£400 | Inhibits regrowth |
| Gutter clear (with the job) | from £60 | Clears shed moss |
Worked example: Soft-brush moss removal, a full biocide treatment and a gutter clear on a north-facing 1930s semi roof in Benhall: around £520.
No deposit — moss removal is invoiced on completion. Any tile repairs found underneath are quoted and agreed before we carry them out.
The workmanship carries our written guarantee; the biocide treatment keeps working on spores for months after application, and fitted zinc strips inhibit regrowth for years.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Moss removal is external and low-impact, but it's messy on the ground below — we sheet the area, bag the moss and leave your borders and patio clean. You do not need to stay home for external work - we just need power and access agreed in advance.
Cheltenham's shaded, damp conditions mean moss returns, so we treat in a dry window and can fit zinc strips to slow regrowth for years. Cheltenham's sheltered vale position brings damp Cotswold-edge autumns and heavy leaf fall from the town's many mature trees, which keeps north-facing slopes slow to dry.
"Annual moss treatment on our Regency terrace on Montpellier. The north slope was growing a thick mat every two years. Since I started the annual biocide programme the valleys have stayed clear all year. Worth every penny."
"Had physical removal and biocide on our Victorian semi in Prestbury — the north slope backing onto the woodland had about 25mm of moss mat. Completely cleared, valleys flushed, and biocide applied. The difference is remarkable."
"Set up an annual treatment plan for our Leckhampton property. The wooded garden means the north slope grows moss faster than anywhere else. First year saw them do the full removal — subsequent years are the annual biocide top-up. Far cheaper than fixing a leak."
A standard 3-bed semi costs £250–600 for a full moss scrape and biocide treatment. Valley clearing as part of the same visit is usually £80–150 extra. All quotes are free.
Yes. Moss retains moisture against tile surfaces, accelerating frost damage on clay tiles and mortar failure in ridges. Cheltenham's escarpment moisture and mature tree cover means moss growth is faster than most Midlands towns.
A single treatment keeps regrowth suppressed for 3–5 years. North-facing slopes near the Cotswold fringe will see faster regrowth and benefit from a 3-year programme.
North-facing wooded or valley locations: every 2–3 years. South-facing exposed roofs: every 3–5 years. Properties near Leckhampton Hill or Regency tree-lined streets need more frequent treatment.
Physical scraping done incorrectly can damage clay peg tiles and Welsh slate. We use soft bristle brushes only. Biocide treatment alone is always our preferred first approach where moss is not yet a thick mat.
No. Pressure washing dislodges granules from concrete tiles and can crack clay tiles and slate. The correct method is dry scraping then biocide treatment.
Yes if left untreated. Moss mat raises tile edges disrupting lap, allowing water past the waterproofing. It blocks valleys and gutters. Left 5+ years it causes measurable structural damage.
We survey moss and lichen growth for free across Cheltenham and provide a written treatment recommendation before any commitment.
0124 235 2251Moss thrives on Cheltenham roofs because of the town's damp Severn Vale setting and heavy tree canopy. North-facing slopes that never dry out, and roofs shaded by the mature limes and chestnuts of Pittville, the Park, Tivoli and Lansdown, hold the moisture that moss needs. The porous concrete tiles of the post-war estates — Hester's Way, Benhall, Springbank — are especially prone, their rougher surface giving moss a foothold that smooth Welsh slate resists for longer.
The single most important thing to know about roof moss is how it should not be removed. Pressure washing a tiled roof is actively damaging: it strips the protective surface off concrete tiles, forces water under the laps, and dramatically shortens the roof's life. We never pressure wash tiled roofs. Instead we soft-wash and hand-scrape the moss, then apply a biocide that kills the spores and slows regrowth — the method that clears the roof without wrecking it. Any Cheltenham firm offering to jet-wash your tiles is telling you they don't understand roofs.
Because of the local damp and canopy, Cheltenham roofs regrow moss on a predictable cycle, and north-facing and tree-shaded roofs benefit from treatment every few years rather than a one-off. We can advise on a sensible interval for your specific roof and aspect, and combine moss treatment with a gutter clear, since the moss and debris that come off the roof are exactly what block the gutters below.
NFRC maintenance guidance and tile manufacturers advise against high-pressure washing of tiled roofs, because it erodes the tile surface and drives water under the covering. Soft-washing and biocide treatment are the recognised methods for removing moss without damaging the roof.
