Tiled vs glass vs polycarbonate conservatory roofs: an honest comparison
Polycarbonate (£3,000–£6,500) is the budget refresh for fair-weather rooms. Glass (£6,000–£12,000) keeps the light while fixing most comfort problems. Tiled solid roofs (£8,000–£14,000) cost most but turn the conservatory into a genuine year-round room. The right choice depends on how you use the space, not on the sales pitch.
The three-way choice in one paragraph
Every conservatory roof replacement on Teesside comes down to the same three options. Polycarbonate is the cheap refresh: it stops leaks and brightens the room but barely improves comfort. Modern glass is the middle way: a sealed-unit roof that keeps the sky view while cutting heat loss, glare and noise dramatically. A tiled solid roof is the transformation: the conservatory stops being a conservatory and becomes a room. None is universally best, and anyone who tells you otherwise before asking how you use the room is selling, not advising.
Head to head
| Polycarbonate | Glass | Tiled solid | |
|---|---|---|---|
| Typical cost | £3,000–£6,500 | £6,000–£12,000 | £8,000–£14,000 |
| Winter warmth | Poor to fair | Good | Excellent |
| Summer heat control | Fair (with tints) | Good (solar glass) | Excellent |
| Overhead light | High | Highest | None (unless roof windows added) |
| Rain noise | Loud | Quiet | Silent |
| Typical lifespan | 10–15 years | 20–30 years | 30+ years |
| Feel of the room | Conservatory | Conservatory, improved | Extension |
Choose polycarbonate when
The budget is the deciding factor, the conservatory is genuinely a fair-weather room, or the plan is to sell in the next few years and you want leaks fixed and the roof presentable without major spend. Modern multiwall panels in opal or bronze tints are a real improvement on the yellowed sheet they replace; just go in clear-eyed about what they cannot do in January.
Choose glass when
The overhead light and the view of the sky are the reason you have a conservatory at all. Today's solar-control, self-cleaning sealed units fix most of what was wrong with old glass roofs: winter heat loss drops by well over half, the summer greenhouse effect is largely reflected away, and rain noise falls to a murmur. North-facing conservatories and shaded plots especially suit glass, where a solid roof would leave the room gloomy.
Choose a tiled roof when
You want the room every day, not every so often. A solid insulated roof is the only option that makes a conservatory behave like the rest of the house: hold heat through a Teesside winter, stay bearable in a heatwave, and silence the rain. It is also the only upgrade estate agents consistently treat as added living space. Roof windows at £500 to £900 each claw back overhead light where you want it, and a white vaulted ceiling keeps the room bright.
The questions to settle it
Three questions resolve nearly every case. How many months a year do you want to use the room? If the answer is twelve, rule out polycarbonate. Is overhead light a must-have or a nice-to-have? If must-have, choose glass; if negotiable, a tiled roof with roof windows usually wins on comfort. And what is the honest budget? Stretching to a solid roof is worth it for daily use, but a well-specified glass roof beats a solid roof bought with corners cut.
