Polycarbonate vs glass
Polycarbonate panels are softer than glass and scratch easily. They're cleaned with a soft-bristle pure-water brush, worked along the corrugations of the panel and rinsed top-down — never with stiff brushes, pads, or pressure.

The service, in plain EnglishConservatory roof cleaning,
Conservatory roof cleaning,
done properly —
end to end.
No jargon, no upsell. Just what you're actually buying, when it's worth doing, and why a professional makes the difference.
What it is
Specialist exterior cleaning of conservatory roofs — glass or polycarbonate — including the panels, glazing bars, ridge, finials, fascia trims, hidden mini-gutters and side glass. Cleaned with a soft pure-water reach-and-pole system from ground level.
Who it's for
Homeowners across Fareham, Gosport, Portchester, Whiteley, Cosham, Havant and Leigh Park whose conservatories are darker than they used to be, who can see green algae on the panels, or who haven't had the roof touched since installation.
When you need it
Once a year is right for most conservatories. South-facing roofs and those near mature trees pick up algae and leaf-mulch faster. Always worth doing in spring so you get the summer with full natural light back.
Why professional matters
A neglected conservatory roof loses light dramatically — the room feels darker, damper and colder. A proper exterior clean restores up to 90% of the original light transmission and rinses the hidden mini-gutters that block invisibly from below.
What happens if you leave itSmall problem now.
Small problem now.
Expensive problem later.
Green algae blocking the light
Algae and lichen on polycarbonate panels can cut light transmission noticeably — the conservatory feels gloomy long before you realise why.
Blocked hidden mini-gutters
The small gutters along the conservatory eaves block invisibly from below. Overflow tracks down the side glass and onto the framework, accelerating staining and damp.
DIY damage to polycarbonate
Bristle brushes, pressure washers and harsh chemicals can permanently scratch or craze polycarbonate panels. The damage isn't reversible.
Lost resale appeal
A dirty conservatory roof is one of the first things buyers see from upstairs windows on a viewing. It reads as 'neglected extension', not 'extra room'.
How the job runsA clear, repeatable
A clear, repeatable
5-step process.
- 01
Site check & quote
Quick visit (or photos for straightforward roofs). Panels counted, framework inspected, hidden gutter run noted.
- 02
Protect surroundings
Side glass, garden, decking and patio furniture protected as needed. Pets brought inside.
- 03
Soft pure-water clean — panels
Each panel washed with a soft-bristle brush and deionised water. Polycarbonate cleaned along the corrugations, not across them, to avoid micro-scratching.
- 04
Frames, finials & mini-gutters
Glazing bars, ridge, finials and the hidden mini-gutter run all cleaned and flushed. Side glass cleaned to finish.
- 05
Walk-around + light-check
Final inspection from inside the conservatory so you can see the difference in light immediately.
What you actually getConcrete outcomes.
Concrete outcomes.
No fluffy promises.
Light restored
Properly cleaned panels and frames let visibly more light into the conservatory — the easiest 'wow' upgrade to a tired-looking extension.
No scratching
Soft brush + pure water means polycarbonate isn't damaged the way DIY brushes and pressure washers will damage it.
Hidden gutters cleared
The eaves mini-gutter is cleared and flushed at the same time — solving overflow problems most people don't even know they have.
Full framework cleaned
Glazing bars, ridge, finials and trims are all detailed — not just the panels. The whole roof reads as cared-for.
Frees up resale value
A bright, cared-for conservatory is a usable room. A dim, mossy one is a project. Cleaning costs a fraction of what 'project' takes off the asking price.
Annual round-up
Easy to book in alongside an external window clean once a year — usually less hassle than chasing it as a one-off.
Method, materials & detailThe proper standard —
The proper standard —
explained.
Conservatory roofs are a different animal to standard glazing. The panels are fragile, the bars trap dirt, and there's a whole hidden mini-gutter that nobody ever sees. Here's how the job is done properly.
Glazing bars and ridge detail
The aluminium or UPVC bars between panels are where most of the moss and algae actually grows. They're agitated and flushed independently from the panels. The ridge and any finials are detailed by hand.
Eaves mini-gutters
The narrow gutter that runs along the conservatory eaves blocks invisibly with grit and leaf fragments. It's cleared and flushed on every roof clean. This is often the single biggest contributor to visible side-glass staining.
Frames, fascia trims and side glass
External UPVC frame trims and the side glass below the roof are washed at the same time, so the whole structure looks consistent.
What we don't do (yet)
Pitched main-roof cleaning isn't offered — the equipment for safe domestic main-roof work isn't in place. Render, patio and driveway softwashing is offered separately and is covered by a 12-month guarantee.
