Professional roof moss removal and biocide treatment across Cheltenham and Gloucestershire. Soft wash methods that protect clay tiles and natural slate. Annual treatment plans for properties in high-growth zones. Free condition surveys.
Cheltenham'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 →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.
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.
"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.
