The service
Give your roof attention before moss takes over
A moss-covered roof dominates the look of an otherwise well-kept property. Loose clumps also fall into gutters and onto paths below. Roof cleaning tackles the organic growth itself. LBS uses softwashing and biocide treatments, planned around your particular roof.
This service is for domestic and commercial owners who want to improve their roof without jumping straight to replacement. Visible moss, repeated debris in gutters and widespread green or black staining are all good reasons to enquire. If you know of leaks or broken tiles, mention them at the start, as those need repair rather than cleaning.
Professional judgement matters because roofs differ in material, age, pitch and condition. A good plan considers the roof and surrounding property, and sets realistic expectations about weathering and how older materials look after treatment.
Based in Bromley, LBS works across the surrounding area with owner Leon Smith as your direct contact. Roof cleaning starts from £599, with a free, clear quote before work begins and the price as quoted. LBS has £5 million public liability insurance, and a moss-free guarantee is available.
If it's left
Why roof moss deserves more than a glance
Moss doesn't automatically mean a roof is failing, but heavy growth creates real maintenance problems. Knowing what they are helps you choose cleaning for the right reasons.
Moisture held against tiles
Moss acts like a sponge, keeping parts of the roof damp for longer. On weathered materials, repeated wetting and freezing speeds up deterioration.
Blocked gutters
Clumps loosen in wet or windy weather and wash into gutters, blocking outlets and causing overflow down your walls.
Defects hidden beneath growth
A dense covering makes the roof hard to assess. Removing it can reveal slipped or damaged tiles that need attention before they let water in.
Unnecessary replacement
A dirty roof looks more worn than it is. Replacing a serviceable roof because of its appearance is a very expensive mistake.
Common mistakes
- Treating roof tiles like patio slabs. Aggressive pressure washing can damage tiles and force water under them.
- Climbing onto a mossy roof without proper access. Moss makes surfaces slippery and some materials are fragile.
- Assuming cleaning will fix a leak, when the cause may be tiles, flashing or joints.
- Expecting every roof to change colour instantly and evenly. Biocide treatments keep working after the visit.
- Forgetting the gutters. Moss from the roof ends up there, so it's worth discussing both together.

What you get
Why homeowners choose LBS
Simple to arrange
Discuss your roof directly with Leon, who quotes and does the work, so nothing gets lost between salesperson and crew.
No roof climbing for you
A roof isn't a place for DIY. Leon handles access and works with the roofing material in mind.
Protect the roof you have
Removing moss reduces trapped moisture and keeps debris out of gutters, helping your existing roof stay in good order.
A fraction of replacement cost
Roof cleaning starts from £599, quoted before work begins, which is a small outlay compared with re-roofing.
Results customers notice
Anna Dodd said, “Our roof looks brand new!” and “The price was exactly as quoted.” Her neighbours noticed the difference too.
Insured, with a guarantee available
LBS has £5 million public liability insurance, and a moss-free guarantee is available. Ask Leon for the details when quoting.
In detail
Roof cleaning informed by materials, growth and surroundings
Concrete tiles, clay tiles and slate
Concrete and clay tiles both develop moss and staining, but their surfaces and weathering differ. Age, earlier damage and individual components matter alongside the material itself.
If you're unsure what covers your roof, say so when enquiring. Leon will advise on suitability rather than treating every covering the same way.
Softwashing and biocide treatments
LBS roof cleaning uses softwashing and biocide treatments rather than blasting the roof like a driveway. Softwashing uses low pressure, so tiles and their weatherproofing are respected.
Biocide treatment acts on biological growth, and visible improvement continues over the following weeks as dead growth weathers away. Leon will explain what to expect for your roof.
Shade, trees and recurring growth
Moss favours damp, shaded conditions. North-facing slopes, nearby trees and sheltered areas stay wet longer, which is why growth often concentrates on one side of a building.
Cleaning doesn't move the trees or change the roof's orientation, so future growth depends partly on those conditions. Ask about follow-up care and the moss-free guarantee available.
Homes and commercial properties
For homeowners, a clean roof lifts the whole look of the property without changing its character. Murat Ertekin wrote, “For any roof cleaning I highly recommend these guys.”
Roofing companies trust LBS too: Sam Nicholas, from a roofing firm, said they have used Leon numerous times and their clients are always delighted with the results. Commercial jobs are planned around the building layout and site access.
Signs your roof needs cleaning
Thick cushions of moss along the tile edges, green or black streaks running down the slope and clumps of moss collecting in your gutters or on the ground are the most common signs. Lichen, which looks like flat grey or yellow patches, can also build up on older tiles and dull the whole roof.
If your gutters keep blocking even after clearing, moss washing off the roof is often the reason. Treating the roof as well as clearing the gutters deals with the source rather than the symptom.
Many homeowners also choose roof cleaning before selling, because a roof covered in moss is one of the first things buyers notice from the street. A cleaner roof, paired with clean driveways and paths, gives the whole property a cared-for look in listing photos and viewings.
