Roof Cleaning & Moss Removal in Falkirk & Central Scotland
Moss doesn’t just look untidy — it holds water against your tiles, works into the joints, blocks your gutters and valleys, and speeds up wear. F J Allan & Sons clean and treat roofs across Falkirk, Stirling and the Forth Valley, restoring the look of your home and extending the life of your roof.
Our roof cleaning services
Moss removal
Careful hand-scraping and brushing to lift built-up moss without damaging the tiles or coating.
Soft washing
Low-pressure cleaning that removes algae, lichen and dirt without the tile damage high-pressure jets can cause.
Biocide treatment
A treatment that kills off spores and keeps moss and algae from coming straight back.
Gutter & valley clearing
Clearing the debris moss sheds into gutters and valleys — where it causes blockages, overflow and damp.
Why clean your roof?
Moss holds water
Trapped moisture works into tile joints and accelerates frost damage and wear.
It blocks gutters & valleys
Shed moss dams your drainage, so water spills over — a top cause of damp inside.
It restores kerb appeal
A clean roof instantly lifts the look of the whole house — and its value.
Why choose F J Allan?
We clean roofs the safe way — soft washing and careful moss removal, not aggressive jet-washing that strips the tile surface and causes leaks. And because we’re roofers, we spot any slipped tiles or failing pointing while we’re up there. Clear fixed prices, tidy work, fully insured.
What affects the cost of roof cleaning?
Priced on the job:
- Roof size and pitch.
- How much moss/algae there is.
- Access and whether gutters need clearing too.
- Whether you add a biocide treatment to keep it clean longer.
Free look, then a clear fixed price.

What our customers say
Roof cleaning FAQs
Is pressure washing safe for my roof?
High-pressure jetting can strip the protective surface off tiles and force water under them. We use safe soft washing and hand removal instead.
How long before the moss comes back?
A biocide treatment keeps a roof clean for years; without it, moss gradually returns depending on shade and trees.
Will you check my roof while you’re up there?
Yes — we flag any slipped tiles, failed pointing or gutter issues we spot, so small problems get caught early.
How often should a roof be cleaned?
Every few years is plenty for most homes; shaded roofs or those under trees may need it more often.
