Let the light back into your conservatory

A conservatory lives or dies by its light, and the roof is where that light gets lost. Sitting flat to the sky, conservatory roofs collect everything that falls on them — algae, moss, leaf debris and a green film that builds up in the glazing bars until the room underneath feels permanently dim and a bit sorry for itself.

It's also the part nobody can easily reach, so it tends to get ignored for years. Cleaning the roof properly — panels, bars, finials and the valleys where debris gathers — is often the single thing that makes a conservatory feel like a room you want to sit in again.

What conservatory roof cleaning covers

• Roof panels cleaned — glass or polycarbonate
• Glazing bars cleared of the green build-up between panels
• Finials and the roof ridge cleaned
• Valleys and gutters around the roof cleared of debris
• Frames and visible trims wiped down

How we clean a conservatory roof

1. Assess the roof

   We check whether it's glass or polycarbonate and look over the bars, finials and valleys so we treat each part correctly.

2. Clear the loose debris

   Leaves and moss are cleared from the panels, valleys and gutters first, before any washing begins.

3. Clean panels and bars

   Panels are washed and the glazing bars worked along with a soft brush — that green line between the panels is where most of the grime hides.

4. Rinse and finish

   The whole roof is rinsed down, including finials and ridge, so it dries evenly and clear.

The room you'd forgotten you had

Because the roof is out of sight and out of reach, its decline is gradual — you don't notice the room getting darker until it's a space you avoid. Clearing years of green film off the panels and bars can transform how much daylight comes through, which changes how warm and usable the whole conservatory feels. It also stops moss and debris trapping moisture against the seals and valleys, where it slowly does damage.
