Roof Moss Removal in Cobham
Moss is the single biggest cause of premature tile failure in Cobham. Once colonies thicken, they hold water against the tile, freeze in winter and crack the surface glaze. Our two-stage removal process strips the moss safely and prevents it returning.
What's included
- Hand-scrape removal — no pressure damage
- DEFRA-approved biocide kills the root, not just the surface
- All moss bagged and removed from site
- Gutter and downpipe clearance included
- 12-month no-moss guarantee
Our process
-
Step 1
Inspection
We assess moss depth, tile condition and any cracked or slipped tiles before quoting.
-
Step 2
Manual scrape
Heavy moss is removed tile-by-tile with plastic scrapers to protect the glaze.
-
Step 3
Biocide soak
A low-pressure biocide application kills remaining spores so regrowth is delayed by years, not months.
-
Step 4
Clear-up
Gutters cleared, downpipes flushed, paths jet-washed and all waste removed.
Frequently asked questions
Does moss damage roof tiles?
Yes. Moss holds moisture against the tile surface. In Cobham's freeze-thaw winters this expands inside micro-cracks and shatters the glaze, shortening tile life by 10–20 years.
Why does my roof get so much moss?
Cobham sits in a damp, sheltered pocket of Surrey with mature tree canopy. North-facing pitches receive less UV, which lets airborne moss spores germinate quickly.
Can I remove moss myself?
We strongly advise against working at height without proper PPE and fall arrest. Domestic pressure washers also damage tile glaze irreversibly.
