What gets cleaned

The roof is the bit you look at

No one sits in a conservatory looking at the frames. They sit under the roof and look up through it. So the roof decides if the room feels clean or tired.

The roof, from the ground

Glass or polycarbonate, cleaned with a pole from outside. No one walks on it. The roof will not take a person’s weight. The panels crack long before they look like they will.

Frames, bars and finials

The green shows most on the white glazing bars between the panels. We do the ridge, finials and cresting too. Those are the fiddly bits at the top that get missed.

The little gutters round it

These gutters are shallow and block fast. When they are full, they tip water straight down the frame. That is how the green streaks start.

Pure water, so it dries clean

The water has nothing in it, so it dries off the glass without spots. That counts most on a roof. You can never reach up and wipe it after.

Worth knowing

Why conservatory roofs go green

It is not really dirt. The roof is nearly flat and stays damp. Nothing brushes it, and in winter it hardly ever dries out. Algae love that.

It starts in the channels

On a plastic roof, the green grows inside the flutes. It also grows along the joins, where water sits longest. That is why it looks like stripes, not patches.

Shade makes it faster

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

You notice it from inside

From the garden, a roof can look fine. Sit under it on a bright day and each streak shows against the sky. That is when most people ring.

Once or twice a year is plenty

This is not a four-weekly job. Most need doing once a year, or twice if in shade. Few jobs outside make a bigger change you can see.

One honest limit

Cleaning is cleaning. A polycarbonate roof that has gone cloudy or yellow from years of sun cannot be washed back. Nor can algae that has got inside the flutes, where the panel is sealed. Washing the outside will not fix either — only a new panel will. I will tell you when I look, not take your money and let you down.

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.
