Roof Cleaning in Henley‑on‑Thames

Henley‑on‑Thames is renowned for its riverside setting, mature woodland and period architecture. While that makes for a stunning place to live, the combination of high humidity from the Thames, sheltering tree canopies and older roofing materials creates ideal conditions for moss, algae and lichen to take hold — particularly on north‑facing slopes and shaded sections.

Untreated moss roots work underneath tile edges, gradually lifting them and allowing water to penetrate. During colder months, trapped moisture freezes and expands, cracking tiles and accelerating deterioration. A professional roof clean removes this growth safely, and a biocide treatment helps prevent it returning for years.

After cleaning your roof we apply a professional‑grade biocide that penetrates the tile surface, killing moss and algae spores at root level. The treatment continues working for months after application, significantly slowing regrowth and keeping your roof looking cleaner for far longer than washing alone.

For Henley properties surrounded by mature gardens, overhanging oaks and riverside vegetation, this treatment is particularly valuable. It means you can typically go two to five years between cleans rather than seeing rapid regrowth within months. The biocide is safe for surrounding plants and guttering when applied by a trained professional.
