Soft wash biocide treatment — no high-pressure washing. Covering all SO51 postcodes. Free quotes.
Romsey's position in the Test Valley watermeadows creates the most challenging moss growth conditions of any location we cover. Properties near the Winding Hill and the river watermeadows are almost permanently damp on north-facing slopes — moss grows back faster than anywhere else in Hampshire. The Victorian stock in the town centre with its lime mortar and clay tile is particularly susceptible. We treat in Romsey every season and understand the specific conditions in this Test Valley location.

Request Free QuoteMoss thrives in persistent moisture. In Test Valley watermeadow position — the most persistently humid location in our coverage area, north-facing slopes and valley areas remain damp for extended periods — ideal conditions for rapid moss establishment. The Georgian and Victorian town centre stock with 1930s to 1960s suburban expansion at Cupernham and North Baddesley means that Welsh slate and clay tile on period town centre properties, concrete interlocking on suburban stock roofs are the primary substrate across Romsey. Concrete interlocking tile is more susceptible to surface moss growth than clay or slate — the surface texture retains moisture better and provides better anchorage for moss roots.
We use soft wash biocide application — low-pressure delivery of moss-killing solution that kills growth at the root without the surface damage that high-pressure washing causes. On concrete tile roofs across Romsey, high-pressure washing strips the tile surface and erodes pointing. Dead moss weathers away over 3 to 6 months after treatment, leaving a biocide residue that suppresses regrowth for 2 to 4 years in Test Valley watermeadow position — the most persistently humid location in our coverage area.
Valley blockage is the most urgent moss-related issue in Romsey. Debris accumulating in valleys — moss growth, leaf fall, lichen material — blocks the drainage channel and causes water to back up under the tile covering. In Test Valley watermeadow position — the most persistently humid location in our coverage area, a blocked valley in October typically causes a visible damp patch before Christmas. We carry out valley clearing as a standalone service or as part of a full roof treatment, with inspection of tile condition included.
