What should Northwood homeowners know?
The Frithwood estate and roads around the station hold Edwardian and interwar detached houses under plain clay tiles, with tile hanging, half-timbered gables and tall chimneys. Northwood Hills, to the south, has 1930s semis with hipped roofs. Modern rebuilds and blocks of flats add large flat roofs.
What goes wrong on Northwood roofs?
Tile hanging and gables. Vertical tile hanging and timbered gables lose tiles and let water in behind the timber.
Steep roofs, old nails. Interwar plain tiles on steep pitches slide once their nails corrode.
Heavy tree cover. Northwood’s mature trees drop leaves into valleys and gutters, causing overflow leaks.
How do we do roof cleaning and moss removal?
We remove moss by hand, soft wash the roof at low pressure and apply an HSE-registered professional biocide, exactly as its label directs. We do not pressure wash tiled or slate roofs. It strips the surface off concrete tiles and brings moss back faster, and on slate it drives water under the laps.

Our process
What you get
- 01
Hand removal
Moss scraped off by hand, working down the roof without walking on fragile tiles.
- 02
Soft wash
Low pressure only, so the tile surface and the laps are untouched.
- 03
Biocide
Kills moss, algae and lichen on contact; the dead growth then weathers away over the following weeks and months.
- 04
Gutters and photos
Gutters cleared of debris and the roof photographed: any slipped tiles noted.
