What gets cleaned

The roof is the bit you actually look at

Nobody sits in a conservatory admiring the window frames. They sit under the roof, looking up through it — which is why the roof is the part that decides whether the room feels clean or tired.

The roof, from the ground

Glass or polycarbonate, cleaned with a pole from outside. Nobody walks on it — a conservatory roof will not take a person’s weight, and the panels crack long before they look like they will.

Frames, bars and finials

The white glazing bars between the panels are where the green really shows. Ridge, finials and cresting too — the fiddly bits at the top that get skipped.

The little gutters round it

Conservatory gutters are shallow and block quickly. They tip water straight down the frame if they are full, which is how the green streaks start in the first place.

Pure water, so it dries clean

The water has nothing dissolved in it, so it dries off the glass without spotting. That matters most on a roof, because it is the one surface you can never reach up and buff afterwards.

Worth knowing

Why conservatory roofs go green

It is not really dirt. A conservatory roof is a flat-ish surface that stays damp, gets almost no traffic and rarely dries out fully in winter — which is close to ideal for algae.

It starts in the channels

On a polycarbonate roof the green grows inside the flutes and along the joins where water sits longest. That is why it looks like stripes rather than patches.

Shade makes it faster

A roof under a tree or on the north side of the house stays wet for days after rain. Same conservatory, same age, twice the green.

You notice it from inside

From the garden a roof can look fine. Sit underneath on a bright day and every streak shows against the sky, which is when most people ring.

Once or twice a year is plenty

This is not a four-weekly job. A conservatory usually wants doing once a year, twice if it is shaded, and it makes a bigger visible difference than almost anything else outside.

One honest limit

Cleaning is cleaning. If a polycarbonate roof has gone cloudy or yellowed from years of sun, or algae has got inside the flutes where the panel is sealed, washing the outside will not fix that — nothing will, short of replacing the panel. I will say so when I look rather than take the money and leave you disappointed.

What customers say

Real reviews, not stock quotes

These are about window, gutter and UPVC work rather than conservatories specifically — but they are real, they are recent, and they are all on the Facebook page in the customer’s own words.

Questions

Before you ask

Do you clean the conservatory roof?
Yes — roof, frames and glass. The roof is the part that makes the difference, so leaving it out would rather miss the point. It is all done from the ground with a water-fed pole.
Do you walk on the roof?
Never. A conservatory roof will not take a person’s weight and the panels give way with very little warning. Everything is reached from the ground on a pole, which is safer for me and considerably safer for your roof.
Will it get rid of the green completely?
Off the surface, yes — the glazing bars and the outside of the panels come up properly. If algae has got inside a sealed polycarbonate flute, that is behind the plastic and cannot be washed out. I will tell you which one you have got when I look.
How often should a conservatory be cleaned?
Once a year for most, twice if it sits in shade or under a tree. It is not a job that needs doing on a round — it is a job worth doing properly when it needs it.
Do you clean the inside of the roof too?
The inside is a different job and depends entirely on the ceiling height and what is underneath. Ask when I am there and I will tell you honestly whether it is worth doing.
What about the gutters around the conservatory?
Worth doing at the same time. They are shallow, they block fast, and when they overflow they run straight down the frames — which is a large part of why the green comes back so quickly.
