Professional soft-wash moss and lichen removal. No pressure washing — we protect your tiles while eliminating the growth. Covering Yarm, Eaglescliffe, Kirklevington, Ingleby Barwick and the surrounding area.
Professional soft-wash moss and lichen removal. No pressure washing — we protect your tiles while eliminating the growth. Roof cleaning from £300 depending on size. Free surveys.
Low-pressure application of a proprietary moss-killing solution. Kills moss, lichen and algae at the root without tile damage.
Gentle brushing to remove dead moss after biocide treatment. Never pressure washing.
Manual clearance of accumulated moss from ridges, valleys and gutters where growth is heaviest.
Post-treatment biocide coating that inhibits regrowth for 3–5 years.
Combined gutter clearance as part of the roof clean — dead moss washed into gutters is cleared at the same time.
Annual or biennial maintenance visits to keep the roof clear long-term.
Yarm's housing stock is predominantly Georgian townhouses on the High Street and adjacent streets with clay plain tile and Welsh slate; Victorian semis on the residential fringe; modern detached on the outskirts toward Eaglescliffe. Knowing the specific roof types and their failure patterns is what separates a knowledgeable local roofer from a national firm that sends whoever's nearest.
River Tees on three sides creates higher humidity than inland towns, accelerating moss growth and mortar decay. Conservation area status applies to much of the town centre, restricting material choices on period properties. This directly affects how quickly specific problems develop and which repair approaches last longest in local conditions.
Lead flashing failure on Georgian and Victorian town centre properties; moss accumulation from river humidity on north-facing slopes; clay plain tile slippage on older properties; conservation area material constraints. We attend these jobs regularly across Yarm and carry the most common materials on the vehicle.
Roof cleaning from £300 depending on size. Free surveys. No call-out fee.

Moss and lichen growth rate in Yarm is driven by three factors: slope orientation (north-facing slopes get less UV), shade from trees or adjacent buildings, and local humidity. River tees on three sides creates higher humidity than inland towns, accelerating moss growth and mortar decay — conservation area status applies to much of the town centre. Properties in Yarm that face north or sit in the shade of mature trees accumulate moss significantly faster than equivalent south-facing exposed properties. For these properties, a shorter treatment cycle of 2–3 years is more cost-effective than waiting until growth becomes heavy.
Pressure washing is not a legitimate roof cleaning technique on any Yarm property. It strips the protective aggregate surface from concrete tiles, forces water under tile laps, and often dislodges loose tiles on roofs with advancing nail sickness — a common condition on Yarm's post-war housing stock. We use soft-wash biocide treatment as standard — applied at lower pressure than a garden hose, it kills growth at the root without mechanical damage. The growth dies and detaches naturally over 4–8 weeks.
After soft-wash biocide treatment, an anti-moss inhibitor coating applied to the tile surface significantly extends the period before regrowth establishes. On a standard property in Yarm, treated and then coated, the growth-free period extends from the typical 3–4 years to 5–7 years. For properties in Yarm with persistent heavy growth driven by river tees on three sides creates higher humidity than inland towns, accelerating moss growth and mortar decay — conservation area status applies to much of the town centre, this combined treatment programme is significantly more cost-effective than repeated reactive cleans.
Pressure washing strips the protective surface aggregate from concrete tiles and forces water under tile laps. We use soft-wash biocide treatment — lower pressure than a garden hose — which kills growth at the root without damaging the tile surface.
The biocide kills moss and lichen over 4–8 weeks. The growth turns brown and detaches naturally with rainfall and wind. A follow-up brush clean can be done once the growth is dead if a faster visible result is needed.
