Upgrading your conservatory roof is one of the smartest ways to make your home more comfortable and energy-efficient. But how much does a conservatory roof replacement actually cost in 2025 — and is it worth the investment?
In this article, we’ll break down the real costs, factors that affect pricing, and the long-term benefits of replacing your conservatory roof.
Why Replace a Conservatory Roof?
Many older conservatories were built with basic polycarbonate or single-glass roofing. While affordable, these roofs often:
-
Lose heat quickly in the winter
-
Overheat in the summer
-
Suffer from condensation or leaks
-
Have a shorter lifespan compared to modern options
A new conservatory roof solves these issues, giving you a room that’s comfortable all year round.
