If you're researching conservatory roof options, you've probably come across three main choices: polycarbonate, glass, and a solid tiled system. Each has a different balance of cost, comfort and lifespan, and the right choice depends on what you actually want from the room.
We've created a useful comparison chart that you can use to gain further information from.
Polycarbonate roofs
Polycarbonate is typically the cheapest option upfront, which makes it a common choice on lower-cost conservatories. The trade-off is performance, polycarbonate offers the weakest insulation of the three, meaning the room runs hot in summer and cold in winter, and rain noise is noticeably louder than other materials. Most polycarbonate roofs need replacing again within 10 to 15 years.
Glass roofs
Glass is a step up in appearance and insulation compared to polycarbonate, and lets in excellent natural light. It still struggles with temperature extremes, though, particularly solar gain in summer, and while it lasts longer than polycarbonate (typically 20 to 25 years), it doesn't solve the comfort problem that drives most people to consider a roof replacement in the first place.
Tiled, solid conservatory roofs
A solid, insulated roof such as the Guardian Warm Roof system takes a completely different approach. Instead of maximising light at the expense of temperature control, it prioritises insulation, with a U-value of just 0.18 W/m.K compared to roughly 1.8 W/m.K for polycarbonate and 1.0 W/m.K for glass. The result is a room that stays comfortable in both summer and winter, with rain noise reduced to near-silent and a lifespan of 40 years or more.
Which option is right for you?
If budget is the only consideration and you're happy to replace the roof again within a decade or so, polycarbonate remains the cheapest route. If natural light is your absolute priority and you can live with the temperature swings, glass is a reasonable middle ground. But if you want your conservatory to actually function as a usable room all year round, without the recurring cost of replacing a failing roof every decade, a tiled solid roof is the option that solves the problem rather than managing it.
Roof shape also plays a part in which system suits your conservatory best. See how your conservatory's roof type affects a tiled roof replacement, or find out more about the Guardian Warm Roof system we install across Leicester and Leicestershire.
