The best conservatory roof depends on how you use the room. Glass with a solar control coating gives the most light, an insulated solid roof gives the best temperature control for year-round use, and polycarbonate suits a budget or occasional-use space. A solid roof with a central lantern balances light and warmth.
How do the main roof types compare?
| Roof | Best for | Watch for |
|---|---|---|
| Glass | Light, a clear view of the sky | Heat gain unless solar control glass is used |
| Polycarbonate | A low-cost, light roof | Noise in rain and weaker insulation |
| Solid insulated | Year-round comfort | Needs Building Regulations approval and a strong frame |
| Solid with lantern | Light with better insulation | Higher cost, closer to an orangery |
Can I change the roof later?
Often yes, if the frame and base can carry the new roof. Solid roofs are much heavier than glass, so the structure needs a check, and the change generally needs Building Regulations approval.
What decides the choice?
Use matters most: a dining room or home office needs temperature control, while a sun room used in summer can stay with glass. Orientation is the second factor, as south-facing rooms overheat without solar control.
