Tiverton’s Exe Valley rainfall above Devon average combined with mature tree canopy accelerates moss on estate housing. Moss holds moisture against the tile surface, accelerates freeze-thaw damage and can lift tiles over time. Left untreated, it shortens the life of the roof covering. We carry out roof moss removal across Tiverton with low-pressure treatment protecting concrete interlocking tile surfaces. Call 01392 759 295.
Moss removal in Tiverton requires the correct approach to avoid damaging the tile surface. High-pressure washing strips the weathered surface of clay and concrete tiles, accelerating erosion and shortening the tile’s remaining life. We use low-pressure biocide application followed by gentle brushing where necessary. The biocide continues working for months after application, killing residual spores and slowing re-establishment significantly.
After treatment, we carry out a tile condition assessment as part of every Tiverton moss removal visit. Moss growth can conceal cracked tiles, deteriorated ridge mortar and blocked valleys. Identifying these secondary issues at the time of moss treatment prevents them becoming emergency repairs in the following autumn and winter — when Topsham’s — when Tiverton’s weather puts the most stress on compromised areas.
Tiverton’s Exe Valley position produces above-average annual rainfall and persistent winter dampness that creates favourable conditions for moss growth on north and west-facing roof slopes across the town. The Exe Vale and Westexe estate housing, which carries large areas of concrete interlocking tile on shallow-pitched roofs, is particularly susceptible — the shallow pitch reduces run-off rate, keeping the tile surface damp for longer after rainfall events. On these properties, moss removal on a 3-yearly cycle is more cost-effective than the single treatment that some contractors offer, which allows re-establishment before the biocide has fully completed its residual action.
The concrete interlocking tile on Tiverton’s post-war estate housing is the most common surface we treat for moss across the town. Concrete tile’s texture and porosity make it hospitable to moss spores, and the shallow pitch of many estate roofs extends the period of surface moisture after rainfall events. We use a biocide formulated for concrete tile surfaces at the correct dilution rate for the expected re-establishment rate in Tiverton’s climate. Application by low-pressure spray without mechanical brushing is appropriate on sound concrete tile — the abrasive action of brushing is not required and slightly accelerates surface erosion.
Moss removal visits on Tiverton’s estate housing frequently reveal underlying condition issues that have been concealed by the moss growth. On nail-sick roofs, slipped tiles may be held partially in position by the adjacent moss mat and become apparent only when the moss is cleared. Ridge mortar in early stages of failure is concealed beneath moss growth on exposed ridgelines. We carry out a systematic condition check during every Tiverton treatment visit and provide a written condition report. This allows early identification of repair needs that, if left, would become more expensive problems within 1–2 years.

“North-facing rear slope cleared of moss. They explained why high-pressure washing wasn’t suitable. Good professional approach.”
“Moss treatment on our post-war semi. Biocide applied after clearing. Re-growth has been much slower than after previous treatments.”
From £200–£600 depending on property size and extent of moss growth. Free survey. Call 01392 759 295.
High pressure strips the weathered surface of clay and concrete tiles, accelerates surface erosion and forces water under tiles. We use low-pressure biocide treatment that is effective without damaging the tile.
Every 3–5 years for most Tiverton properties. North-facing slopes and those with tree overhang may need attention more frequently due to exe valley rainfall above devon average combined with mature tree canopy accelerates moss on estate housing.
Yes — biocide continues killing residual spores for several months after application. This significantly slows re-establishment compared to mechanical removal alone.
Tile condition, ridge mortar state, valley debris accumulation, and flashing condition. Moss growth often conceals secondary issues that are better addressed at the time of treatment.
Yes — the biocide we use treats moss, algae and lichen. All three are present on Tiverton properties due to the exe valley rainfall above devon average combined with mature tree canopy accelerates moss on estate housing.
