Moss and biological growth on Poets Corner roofs is accelerated by local conditions. We use low-pressure soft washing with professional biocide — safe for tiles, mortar and lead. No high-pressure damage.
Flat roof failure on rear extensions is dominant — 40-60 year old felt comprehensively at end of life. Moss growth on Poets Corner roofs is faster than most inland areas due to local conditions. Central Hove, coastal salt exposure, south-facing extensions receive maximum UV Soft-wash treatment kills moss at the root and includes a post-treatment biocide to prevent regrowth for 3-5 years. Edwardian terraces (1900-1920s), clay tile pitched, 1960s-80s flat-roofed rear extensions
High-pressure washing is the fastest method but also the most damaging. It forces water under tiles, dislodges mortar on ridges and hips, fractures the surface of older concrete tiles, and strips the protective patina from lead. On Poets Corner's older properties — particularly the Edwardian terraces (1900-1920s). — this can cause more damage than the moss itself.
Low-pressure application of professional biocide solution to all biological growth. Dwell time of 15-30 minutes. Low-pressure rinse to remove dead growth — no mechanical stress on tiles or mortar. Post-treatment biocide application to bare surfaces to prevent regrowth. Written roof condition report on completion.
Central Hove, coastal salt exposure, south-facing extensions receive maximum UV On the most exposed north-facing slopes in Poets Corner, biocide treatment typically needs renewing every 3-4 years. South-facing slopes with good drainage need treatment every 5-6 years. We advise on a realistic maintenance schedule during the free survey.

“North-facing slope was black with moss. Treated professionally and it looks like a different roof. The condition report flagged two tiles I wasn't aware of — they fixed those at the same time.”
“Previous roofer had high-pressure washed and cracked two tiles. These used soft wash, no damage, thorough result.”
“Had the roof treated and biocide applied. Two years later and there's no sign of regrowth. Worth every penny.”
Hove neighbourhood with Edwardian (1900-1920s) housing. The dominant roofing maintenance issue in Poets Corner: flat roof replacement on 1960s-80s rear kitchen extensions.
Almost every Poets Corner property has a rear kitchen extension with a flat roof. The vast majority of these were built or re-roofed in the 1960s-80s and are now 40-60 years old. GRP is the correct replacement specification for these south-facing Hove positions.
Every job follows the same clear process — no surprises, no hidden costs, full communication throughout.
We assess moss coverage, identify any underlying tile or mortar issues that the treatment will expose, and quote for the cleaning and post-treatment.
Professional biocide solution applied at low pressure to all biological growth. Dwell time allows the biocide to penetrate and kill growth at the root.
Dead growth rinsed clear at low pressure — no mechanical stress on tiles or mortar. Valleys and gutters cleared of all shed debris during the cleaning process.
Post-treatment biocide applied to bare surfaces to prevent regrowth for 3-5 years. More durable than the pre-rinse application alone.
Every moss removal job includes a written condition report documenting tile, mortar, lead and guttering condition found during the cleaning process.

A full property soft-wash treatment in Poets Corner costs £300-£800 depending on roof size and access. Single slope treatments start from £150. All treatments include post-treatment biocide and a written roof condition report.
Soft-wash treatment is safe for all tile types including clay, concrete, slate and fibreglass. We do not use high-pressure washing which can fracture older tiles and dislodge mortar.
Biocide treatment prevents significant regrowth for 3-5 years on most Poets Corner properties. North-facing slopes and properties near trees may need retreatment after 3 years. South-facing slopes with good drainage typically last 5-6 years between treatments.
Moss retains moisture against tile surfaces, accelerating frost damage and tile deterioration. It blocks valleys and gutters, causing overflow and potential water ingress. In Poets Corner's conditions moss grows faster than inland — it warrants periodic treatment rather than waiting for visible damage.
Consumer biocide products are available but less effective than professional-grade solutions. Application without access equipment risks injury. The roof condition report included with professional treatment is also valuable — often the first indication of issues that would otherwise go unnoticed.
Yes. Every moss removal treatment includes clearing all valleys and guttering of debris shed during the cleaning process. We leave the drainage system clear on completion.
