Glass, solid and hybrid roof pricing, plus the structural checks that decide whether your frames can take the load.
Replacing a polycarbonate roof is one of the highest-impact improvements you can make to an older conservatory, but the quotes vary enormously — usually because people are being quoted for three genuinely different products.
This guide separates those products, then explains the structural survey that has to happen before any of them can be priced properly.
A replacement glass roof keeps the light and adds modern solar-control performance. A solid, insulated roof turns the space into a room you can use all year but reduces overhead light. A hybrid combines insulated panels with glazed sections or a roof lantern.
Cost rises broadly in that order, but the deciding factor is usually how you want to use the room rather than the headline price.
The bigger the span, the more structural support is needed. A solid roof is heavier than polycarbonate, so the existing frames and base have to be assessed before anyone commits to a price — that assessment is part of our survey, not an optional extra.
A plastered and skimmed internal ceiling with downlights costs more than a pre-finished panel ceiling, and it is often the difference between two quotes. Decide which you want before you compare figures.
We'll assess the frames and base, then quote glass, solid and hybrid options side by side.
Often yes, but it must be checked. We survey the frames, base and span before quoting a solid roof, and we will tell you if reinforcement is needed.
Replacing like-for-like glazing usually does not, but changing to a solid roof can bring building control into play. We advise on this at survey stage.
A solid insulated roof or modern solar-control glass both make a substantial difference compared with old polycarbonate.
