Roof Care & Maintenance
Roof cleaning that protects the roof, not just its appearance
A wet, sheltered climate grows moss extremely well. Removing it matters — but the method matters more. We do not put a pressure washer on a slate or tile roof, and we will explain why before we start.

Roof Cleaning: the short answer
Roof cleaning removes moss, algae, lichen and debris from a roof covering and its drainage. Done correctly it protects the covering and restores drainage; done with a high-pressure lance it strips surface material, drives water under the units and can take years off the roof's life.
Who this is for
- Owners with visible moss growth, particularly on north-facing slopes
- Anyone with gutters repeatedly blocked by moss debris
- Sellers preparing a property for market
- Landlords and property managers on a maintenance cycle
Signs you need this work
Thick moss between and over units
Growth that holds water against the covering and lifts the tail of slates and tiles.
Moss fragments in gutters and downpipes
The first practical consequence — drainage blocks and water backs up.
Dark algae staining
Cosmetic on its own but usually a sign of persistent damp on that slope.
Lichen crusting on slates
Slow to remove and easily damaged by aggressive cleaning.
What causes it
Shade and shelter
North-facing slopes and roofs under trees stay wet long enough for moss to establish.
High rainfall
This region provides ideal growing conditions for most of the year.
Overhanging vegetation
Trees drop debris and keep the covering damp. Cutting back is often the most effective single fix.
Rough surfaces
Weathered concrete tiles and textured coverings hold spores far more readily than smooth slate.
Keeping it right afterwards
- Cut back overhanging branches — the single most effective preventative step
- Clear gutters twice a year to stop debris bridging back onto the roof
- Expect to repeat cleaning every four to six years in a shaded, wet position
- Have the roof inspected at the same time so defects are caught early
Helpful roofing advice
Independent guidance from our advice centre — what the symptoms may mean and what your options are, before you commit to any work.
How it works
Our process, step by step
Assess the covering
Some coverings tolerate cleaning well; brittle or delaminating ones do not, and we will say so.
Protect the site
Drainage, planting and access routes covered before work starts.
Manual and low-pressure removal
Scraping and soft washing rather than a high-pressure lance.
Clear the drainage
Gutters, valleys, outlets and downpipes flushed and checked.
Biocide treatment
An optional treatment that slows regrowth for several years.
Inspect while up there
Any defect exposed by the clean is photographed and reported to you.
Why it matters
What you get from doing it properly
Drainage actually restored
The point of a clean is working gutters and valleys, not just a tidier roof.
No pressure washing damage
We will not use a method that shortens the life of your covering.
Defects reported
You get a photographic note of anything found while the roof is accessible.
Common questions

Work that often goes with this
Moss Removal
Moss removal is the targeted stripping of moss growth from a roof covering and its drainage using manual scraping and low-pressure soft washing, followed by an optional biocide treatment to slow regrowth. It is carried out to restore drainage and prevent water being held against the covering.
Gutter Cleaning
Gutter cleaning clears leaves, moss and silt from gutters, hoppers, outlets and downpipes so rainwater leaves the building rather than overflowing down the wall. It is the cheapest preventative maintenance available and prevents damp, pointing erosion and fascia rot.
Preventative Roof Maintenance
Preventative roof maintenance is a scheduled programme of inspection, drainage clearance and minor repair that catches defects while they are still cheap. It is the difference between a fifty-pound repair and a five-thousand-pound one, and it is the single best-value service on this list.
Roof Surveys & Condition Reports
A roof survey is a documented assessment of a roof's condition, remaining service life and defects, delivered as a written report with photographs and prioritised recommendations. It is used for property purchases, planned maintenance budgeting, insurance, dilapidations and settling disagreements about whether a roof needs replacing.
