Moss, algae, and general grime build up quickly on conservatory roofs — especially on polycarbonate panels which can turn green within a season. Our specialist clean removes all build-up and restores full light transmission.
We clean both glass and polycarbonate roof types, and include the frames and guttering as standard.
Why conservatory roofs go green so fast
A conservatory roof is flat-ish, shaded for part of the day and rarely rained-on hard enough to self-clean — perfect conditions for moss and algae. Polycarbonate roofs are the worst for it and can turn visibly green within a single season, especially on the damp, tree-shaded plots common around the villages here. The result is a dim, dirty room below and a tired-looking roof from the garden.
Glass and polycarbonate — handled differently
We clean both, with the method matched to the material: a gentle approach for polycarbonate (which scratches more easily) and a streak-free finish on glass. Either way the aim is the same — clear the growth, restore the light, and leave the room below noticeably brighter.
What's included
Every conservatory roof clean covers the roof panels, the frames and cappings, and the external gutters around the conservatory as standard — not just the glass. We clear the gutter runs while we're there because a blocked conservatory gutter overflows straight down the wall.
How often should it be done?
Once a year keeps most conservatory roofs clear. Shaded or damp positions — under trees, north-facing, or in the lower, damper spots near the rivers — green up faster and may benefit from a more frequent clean. We'll give you an honest recommendation for yours.
