Conservatory Roof Replacement
Swapping an old polycarbonate roof for glass or a solid tiled roof — often the single biggest comfort upgrade available
Pros
- Often transforms a conservatory from a room that’s unusable for months of the year into one used year-round
- A glass roof upgrade keeps natural light while cutting solar heat gain significantly versus old polycarbonate
- A tiled roof conversion can bring the room close to the rest of the house’s thermal performance
Cons
- A solid tiled roof conversion is a bigger structural job — the existing wall plate and frame need checking, and sometimes reinforcing, to take the extra weight
- Not always cost-effective on a very old or poorly built base frame — sometimes a full conservatory replacement works out better value than repeatedly upgrading an ageing structure
About Conservatory Roof Replacement
A large share of conservatories built in the 1990s and 2000s used polycarbonate roofing, which is cheap and lightweight but performs poorly thermally — these rooms are notorious for being unusably hot in summer and cold in winter. There are two common upgrade routes: replacing the polycarbonate with modern high-performance glass, which keeps the light and the open conservatory feel with meaningfully better solar control and insulation than old polycarbonate, but is still a glazed roof; or converting to a solid tiled roof, which effectively turns the roof into an insulated, tiled structure like the rest of the house — the bigger thermal improvement of the two, but it loses the airy glass-roof feel and is the more expensive, more involved option, since the existing frame usually needs checking for load capacity first.

Frequently asked questions
Will a roof replacement need Building Regulations sign-off?
Often yes, particularly for a tiled conversion, since it changes the structure and thermal performance of the room. A FENSA- or Certass-registered installer can self-certify glazing-related compliance as part of the job, rather than needing a separate council building control application.
Are you a conservatory installer yourselves?
No — Compare Conservatories is an independent comparison and information service. We recommend always checking an installer’s FENSA or Certass registration directly before any glazing work begins.
Is all the pricing on this site guaranteed?
No — costs mentioned are typical UK trade-source ranges, not fixed quotes. Always get itemised quotes from more than one registered installer before committing.
What happens after I request a quote?
A partner installer reviews your details and gets in touch to arrange a proper site survey — there’s no obligation to proceed with any quote.
