Soft wash biocide treatment — no high-pressure washing. Covering all SO53 postcodes. Free quotes.
Tell us the job in 30 seconds. No pushy sales, no call-out fee.
Chandler's Ford's large 1930s detacheds in Hiltingbury and around Merdon Avenue have substantial roof areas with multiple valleys and mature garden trees. Autumn leaf fall from the mature oak and beech trees that characterise these gardens blocks valleys within days. The complex multi-valley roofs on the larger Hiltingbury properties require careful physical clearance before treatment — blocked valleys on a multi-valley roof can cause ingress at several points simultaneously.

Request Free QuoteMoss thrives in persistent moisture. In well-drained elevated ground north of Southampton with mature tree canopy, north-facing slopes and valley areas remain damp for extended periods — ideal conditions for rapid moss establishment. The 1930s to 1960s detacheds and semis with large properties in Hiltingbury and around Merdon Avenue means that clay plain tile on 1930s Hiltingbury detacheds, concrete interlocking on 1960s Fryern Hill stock roofs are the primary substrate across Chandler's Ford. 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 Chandler's Ford, 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 well-drained elevated ground north of Southampton with mature tree canopy.
Valley blockage is the most urgent moss-related issue in Chandler's Ford. 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 well-drained elevated ground north of Southampton with mature tree canopy, 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.
