Professional moss removal and roof cleaning in Stivichall. Biocide treatment, soft wash and gutter clearing on 1930s and post-war properties. Free quotes, no call-out fee.
Stivichall's heavy tree canopy accelerating moss growth creates conditions where moss establishes rapidly on north-facing and shaded roof slopes. Moss retains moisture against the tile surface, accelerating freeze-thaw damage to mortar beds, tile faces and ridge pointing. A 20mm moss colony can hold several litres of water per square metre — in winter, that water freezes, expands, and progressively opens every mortar joint it sits against. On CV3's 1930s and post-war properties, neglected moss is one of the primary causes of the repair calls we receive in spring.
We apply a professional-grade biocide to the roof surface using a low-pressure soft wash system. The biocide kills existing moss, lichen and algae at the root. The dead growth then weathers off naturally over the following 3–6 months — we do not use high-pressure washing, which damages tile surfaces and forces water under the tile course. On Stivichall's 1930s and post-war properties, biocide treatment lasts 3–5 years before re-treatment is needed.
Moss debris washed off by rain after treatment blocks gutters and valleys. We include a gutter and valley clear as part of every moss treatment in CV3 — clearing the outlets before treatment and returning to clear debris as the dead moss comes away. Properties in Stivichall with heavy tree cover may need an additional clear 3–4 months after treatment as the bulk of moss debris comes down with autumn rainfall.
On north-facing or tree-shaded slopes in Stivichall, moss re-establishes within 3–5 years of biocide treatment. Properties with southern aspect and good air circulation can go 5–7 years. Annual visual inspection — checking whether green is returning at ridge level — is the simplest maintenance trigger. We offer annual gutter and valley clears with a moss growth check included at no extra cost.

Stivichall’s 1930s and post-war properties creates specific conditions that affect moss treatment and removal work in CV3. The heavy tree canopy accelerating moss growth on all slopes means heaviest moss accumulation of any Coventry suburb due to tree cover — patterns we see repeatedly across Stivichall properties and that require a different approach to the same service in a more sheltered location.
The dominant property type across CV3 is 1930s and post-war properties. For biocide treatment and soft wash, this means working with materials, mortar and fixing systems that are specific to the era and construction method of Stivichall’s housing stock. We carry the tile profiles, lead codes and mortar specifications most commonly required across CV3 in stock, and we assess each property individually rather than applying a uniform approach.
We cover Stivichall and all of CV3 within our standard service window — free surveys within 2–3 working days, emergency call-outs within 2–4 hours. Written condition report and itemised quote provided before any work is agreed. All moss treatment and removal work in CV3 carries a 10-year written workmanship guarantee and is backed by £5m public liability insurance. Call 0247 798 1271 to book a free survey.
The most frequent question we receive from Stivichall homeowners asking about moss treatment and removal is how to distinguish a repair that will hold from one that is masking a deeper problem. Our surveys are designed to answer this honestly: we assess the full roof condition, not just the visible presenting issue, and give you a written report covering current condition, remaining service life, and the full range of options at each maintenance threshold.
Biocide moss treatment on a standard semi in Stivichall costs £150–£300 depending on roof size and moss coverage. Full soft wash with gutter clearing runs £200–£600. We quote before work starts.
No. High-pressure washing damages the tile surface and can force water under the tile course. We use low-pressure soft wash only across all CV3 properties — it removes moss effectively without tile damage.
Biocide treatment typically lasts 3–5 years on CV3 properties. North-facing and tree-shaded slopes in Stivichall re-establish moss faster than open-aspect properties.
Dead moss washes into gutters over the months after treatment. We include a gutter clear in every moss treatment quote for Stivichall to manage this — and recommend an additional clear 3–4 months later if heavy moss coverage was present.
Yes. We work around solar panels on CV3 properties using careful low-pressure application. We do not treat the panels themselves — only the tile surfaces around them.
Yes. After biocide treatment we can apply a long-life zinc or copper strip at the ridge, which leaches a mild fungicide every time it rains and inhibits moss regrowth significantly across Stivichall roofs.
Spring and autumn are ideal — temperatures above 5°C and some moisture for the biocide to activate. Avoid treatment immediately before heavy rain. We can treat year-round across CV3 excluding frost conditions.
