Glass or Polycarbonate — Does Conservatory Roof Cleaning Differ?

The Direct Answer

Glass and polycarbonate conservatory roofs both get cleaned from the ground with poles and pure water, but the approach is not identical. Polycarbonate scratches more easily than glass, so it needs a gentler brush and more careful technique, while glass can take a slightly firmer pure water rinse and dries completely clear with less risk of marking the surface.

Why polycarbonate needs the gentler touch

• It scratches more easily than glass under an abrasive brush or the wrong technique.
• Those scratches are permanent and actually make future grime stick more easily, compounding the problem.
• A soft brush and controlled pressure avoids this entirely, so the roof stays clear rather than getting scuffed over repeated cleans.

Why glass is more straightforward

Glass takes pure water the same way a window does, rinsing to a completely clear finish without the scratch risk polycarbonate carries. The main extra consideration is the pitch and height of a conservatory roof compared to a standard window, which is why it still gets the pole treatment rather than a squeegee.

What's identical either way

Nobody stands on the roof, whichever material it is — most conservatory roofing isn't built to take that weight safely. The box gutter gets cleared first in both cases, since that's where everything that comes off the roof ends up.
