Soft wash
Surface-correct method
Soft-wash roof cleaning — the only method we'll use on a tile roof.
High-pressure 'roof blasting' looks dramatic on social media. It also strips tile coatings, snaps ridge mortar and voids most manufacturer warranties. We don't do it.
Instead, every roof we clean is treated with a low-pressure soft-wash system using a roof-specific biocide. The biocide kills moss, algae and lichen at the spore level, then weather over the following weeks does the rest of the work — gently and without trauma to the tiles or mortar.
Where moss is heavy, we scrape and remove the bulk by hand before treatment, working from a properly secured ladder or access platform. All loose moss is bagged, gutters are cleared of debris, and the property is left tidy.
We work on concrete tile, clay tile, slate and metal roofs across Hampshire and the south coast — for homeowners selling, homeowners staying, and landlords preparing properties for the next tenant.

Why an untreated roof costs you twice.
Moss isn't just cosmetic. Once established on a tiled roof, it damages tiles, blocks drainage and shortens the working life of the entire roof structure.
Tiles crack from the inside
Moss holds water against the tile surface. In winter, that water freezes, expands and splits tiles from underneath. Replacement tiles are often discontinued.
Gutters and downpipes block
Loose moss falls into gutters, blocking them. Overflowing gutters then soak the fascia, soffits and exterior walls — leading to rot and damp.
Insurance claims get harder
Visible heavy moss is increasingly flagged by buildings insurance surveyors as a maintenance issue, which can affect claims for storm damage.
A clear, methodical system — built around your time and your property.
Inspection
We assess the surface, age, material and condition on site or from your photos — and quote in writing.
Preparation
Plants, drains and fragile fixtures are covered. Loose debris is cleared before cleaning begins.
Treatment
The correct chemistry and pressure for the surface — biocides, detergents or pure cleaning where appropriate.
Verification
A controlled rinse, inspection in natural light, and a walk-around with you to check every metre.
Completion
Site left spotless. Aftercare advice and a clear written invoice.
The benefits you'll actually notice — and the ones that pay for themselves.
No tile damage
Soft-wash is the manufacturer-approved approach. We never blast tiles or stand on coated surfaces with hard-soled boots.
Years added to the roof
Removing moss and stopping regrowth genuinely extends roof life — often by 5–10 years compared to leaving it untreated.
Cleaner exterior all round
No more green streaks down the gables, no more moss falling onto driveways and patios with every breeze.
Gutters stay clearer for longer
Less moss on the roof means less debris in the gutters, which means fewer blockages and less damp risk.
Treatment keeps working
Biocide continues to act for months after the visit, suppressing regrowth even after the visible moss is gone.
Better insulation efficiency
Wet, moss-covered tiles transfer heat differently. A dry, clean roof maintains insulation performance — especially relevant after recent winters.
Soft-wash roof cleaning, explained in plain English.
There's a lot of bad information online about roof cleaning. Here's exactly what we do, what we don't, and why it matters.
Why we never pressure-wash a tile roof
Concrete roof tiles have a factory-applied coloured slurry coat on the top surface. High-pressure water strips that coating in seconds, exposing the porous concrete beneath. Within months, the bare concrete absorbs water, freeze-thaw damage accelerates, and the tiles deteriorate faster than they ever would have with moss left alone. The 'clean' look lasts a season; the damage lasts decades.
How soft-wash actually works
We apply a roof-safe biocide (typically benzalkonium-chloride based, sometimes combined with a quaternary ammonium compound) using a low-pressure pump at less than 1 bar. The chemistry kills the cell walls of moss, algae and lichen. Over the following 4–12 weeks, dead growth releases its grip on the tile and is washed off naturally by rain. The roof gets progressively cleaner without anyone walking on it.
Heavy moss removal
Where moss is more than a few millimetres thick, we mechanically remove the bulk before treatment — gently scraping from a roof ladder or scaffold tower. Loose moss is bagged for disposal, never blown into the garden. Gutters are then fully cleared as part of the same visit.
Residential vs commercial roofs
Domestic pitched roofs are quoted per square metre after a quick survey or photos. Larger commercial or barn-conversion roofs are quoted on-site.
