Conservatory roof cleaning — exterior only, done properly.
From inside it looks dull. From outside it's properly grim — moss, lichen and road dust caked across every panel. We treat the surface, flush the drainage channels and bring the finials back. Glass or polycarbonate.

A clean conservatory roof transforms the room underneath it. Where you had a dim, greenish space, you get a bright room flooded with daylight. That's the actual result people notice most — the roof itself looks better too, but the change to the room is what makes people ring us back every year.
How we clean conservatory roofs
We use a ladderless pole system with pure water. No one stands on your conservatory roof, so there's zero risk of cracking a panel or damaging the framework. Conservatory roofs are walked on at your peril — even reinforced glass can scratch, and polycarbonate doesn't take foot pressure well.
Our soft-wash solution lifts algae, moss, lichen and bird mess off the polycarbonate or glass panels, then the purified water rinses it spotless and dries without leaving marks. That matters on horizontal glass where every rain mark would otherwise show.
We clean the aluminium glazing bars and the frames at the same time. For UPVC frames that have gone grey or green, we can restore them to their original white finish as part of the job. Drainage channels and end-caps get flushed too — these block with moss and leaves over the years and that's how water finds its way down the inside of the conservatory wall.
How often should you clean a conservatory roof?
Once a year is enough for most conservatories. If yours sits under overhanging trees or on the north side of the house, twice a year keeps on top of it. We can set up a recurring booking so you don't have to remember.

Will window cleaners clean my conservatory roof?
We will. Many window cleaners won't because it requires specialist pole equipment and takes longer than standard window cleaning. We include it as a core service.
How much does conservatory roof cleaning cost?
Our conservatory roof cleans range from £5 to £10 per pane. The final price depends on the size of the conservatory and how much build-up there is. We'll give you a fixed price upfront after a free site visit.
Will the cleaning damage polycarbonate or glass panels?
No. We use a soft brush head on a carbon-fibre pole with a non-abrasive cleaning solution and pure-water rinse — no jet washing, no harsh chemicals. The same method is manufacturer-friendly for both glass and polycarbonate.
