Self-cleaning glass roof lanterns
Self-cleaning glass has a thin coating on the outer surface that does two things: daylight helps it break down organic dirt, and rain then spreads into a sheet rather than droplets, carrying the loosened dirt away. It is standard on most lantern ranges and is especially useful on glass you cannot easily reach.

In short: A coated outer pane that breaks down dirt in daylight and lets rain wash it away. Guide prices start from £1,295 including VAT, supply only.
How well does self-cleaning glass work?
It reduces cleaning rather than ending it. It works best on glass that sees daylight and regular rain, which a sloping lantern does. Heavy deposits, bird droppings and sap still need a gentle rinse with clean water now and then.
Never use abrasive pads, harsh chemicals or silicone-based products on the coated surface: they can damage the coating. The care guide that comes with your lantern lists what is safe.
Which tint should I choose?
Self-cleaning glass usually comes in clear, blue or neutral tints. Blue and neutral tints also reduce solar heat gain. Clear lets the most light through. Our glass guide compares them.
What does it cost?
On most ranges self-cleaning glass is included as standard, so guide prices below already include it.

Self-cleaning glass roof lanterns: common questions
Do I still need to clean self-cleaning glass?
Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
