Roof Cleaning & Moss Removal

Roof Cleaning Explained

Is Moss Actually Bad for a Roof?

Moss is not only a cosmetic problem. It holds water against the tile, which accelerates frost damage over winter, and thick growth at the tile laps physically pushes tiles apart and breaks the weather seal between them. Washed off by heavy rain, it blocks gutters and downpipes and sends water down the wall instead. Riverstone Roofing Ltd removes moss and algae by hand scraping and controlled soft washing rather than high-pressure jetting, which strips the surface off concrete tiles and can force water under the laps. We clear the gutters and downpipes as part of the job, check the ridges and flashings while we are up there, and tell you about anything that needs attention rather than quietly leaving it. Roof cleaning is quoted free and in writing with a fixed price. Fully insured, rated 10/10 on Checkatrade, working across Lincolnshire, Cambridgeshire and Norfolk.

The Service

Restore Your Roof,
Protect Your Tiles

Moss, algae and lichen don’t just make a roof look tired — they hold moisture against the tiles, block gutters and valleys, and in winter that trapped water can freeze and crack tiles. Left for years, a mossy roof can take real damage.

Our gentle soft-wash approach safely removes moss and growth without the high-pressure blasting that damages tiles, then treats the roof with a biocide to keep it cleaner for longer — restoring its appearance and protecting your investment.

Gentle Soft-Wash, No Damage

Low-pressure cleaning that won’t crack tiles or strip their surface.

Biocide Treatment

Kills off remaining spores so your roof stays cleaner for much longer.

Why It Matters

What Does Moss
Actually Do to a Roof?

Moss is not purely a cosmetic problem. Left long enough it shortens the life of the covering underneath, and this is how.

It holds water against the tileMoss keeps the surface permanently damp, which is what accelerates frost damage over winter.
It blocks gutters and downpipesHeavy rain washes moss off the roof and into the gutters, where it causes overflows down the wall below.
It lifts tiles apartThick growth at the tile laps physically pushes tiles apart and breaks the weather seal between them.
It causes frost damageWater trapped in and under the moss freezes, expands and spalls the surface off concrete tiles.
It restricts ventilationGrowth across eaves and ridge vents cuts the airflow into the roof space that keeps the timbers dry.
It makes the roof unsafe to walk onA heavily mossed roof is slippery, which makes every other repair harder and more expensive to carry out.
It erodes the tile surfaceRoots work into the porous surface of concrete tiles and break it down over time.
It costs you on a surveyNot structural, but a badly mossed roof looks neglected and is routinely flagged in home buyer reports.
