Why Does Nobody Clean Their Conservatory Roof, and What Difference Does It Actually Make?

The Direct Answer

A conservatory roof gets skipped because it is awkward and slightly unnerving to get up close to, so it simply does not get looked at the way a window or a drive does. That means moss, algae and general grime build up for years rather than months, and because the panels sit at a shallow angle directly above a room you sit in, the dirt you are not cleaning is also the dirt filtering the light into that room every day. Cleaned properly from the ground, the difference in how much light actually gets through is bigger than most people expect.

Why it gets worse than a normal roof

• Shallow pitch means rain does not naturally wash growth away the way it does on a steeper roof.
• Polycarbonate and glass panels show algae and grime far more obviously than tiles do, because you are looking through them, not just at them.
• The box gutter at the top, where the conservatory meets the house, collects leaves and moss that nobody ever checks.
• Most people genuinely never look at it closely enough to notice how bad it has got.

How it is actually cleaned

From the ground on extension poles, never by climbing onto the roof itself, which most conservatory panels are not built to take weight on safely. We work the box gutter first so water has somewhere to go, then the panels, bars and finials, finishing with a squeegee pass so each panel dries clear rather than streaky.

What it actually changes

Light transmission through a genuinely grimy conservatory roof can be noticeably reduced. Customers who have not had it done in years are often surprised by how much brighter the room feels afterwards, which is really just the roof doing the job it was designed to do again.

FAQ: Is it safe for polycarbonate panels?

Yes. Pure water and a soft brush at low pressure is gentle enough for polycarbonate and glass, and nobody stands on the roof itself.

FAQ: How often should it be done?

Once a year keeps most conservatory roofs in good shape. Under trees, we would suggest twice.

FAQ: What does it cost?

From £70, covering the roof, frames and box gutter. Full detail on the conservatory roof cleaning page.
