Does your conservatory feel like an icebox in winter and a greenhouse in summer?
You’re not alone.
Thousands of homeowners across East Anglia and the UK are turning to conservatory roof conversion to transform their underused extensions into comfortable, year-round living spaces.
But the benefits go far beyond comfort.
A conservatory roof conversion can result in significant financial benefits - from energy bill reductions to added property value.
In this article, we’ll show you exactly how much you could save, what kind of return you can expect, and why converting your roof is one of the smartest home improvements you can make.
Most older conservatories were built with either glass or polycarbonate roofing.
These materials were quick and affordable to install, but they have one major drawback - they’re terrible insulators.
A typical polycarbonate roof has a U-value of around 1.6 W/m²K to 2.4 W/m²K, compared to a modern Guardian Warm Roof, which achieves a U-value as low as 0.15 W/m²K
What does that mean in practical terms?
U-values measure how well a material prevents heat from escaping. The lower the U-value, the better the insulation.
If your conservatory has a roof with a high U-value, it means it's not retaining heat effectively. This can leave the room freezing in winter and unbearably hot in summer
Because your conservatory lets heat escape so easily, you may find yourself cranking up the heating in the adjacent room to compensate. Or maybe you’ve tried to heat the conservatory itself with electric heaters — a notoriously expensive solution.
In the summer, fans or even portable air conditioning units are often needed just to make the room bearable.
The result? Increased energy bills, wasted electricity, and a space that’s rarely used.
A well-insulated solid conservatory roof can help contain warmth during the colder months and deflect excessive heat in summer - meaning lower energy bills and a room you’ll actually want to spend time in.
The average conservatory roof conversion cost typically falls between £7,000 and £20,000, depending on the style and size of the conservatory.
That’s a significant investment, and for many homeowners, it’s important to understand how that figure translates into long-term value.
Switching to a Guardian Warm Roof can lead to energy bill savings of around £200 per year for a typical UK home.
Over a 25-year lifespan, that adds up to £5,000 in savings—and that's before factoring in ongoing rises in gas and electricity prices.
Another important consideration is maintenance.
Polycarbonate and glass roofs often require cleaning, resealing, or even panel replacement. Solid roof systems, like the Guardian Warm Roof, are engineered to last, cutting down your future maintenance costs dramatically.
So when you ask yourself if the conservatory roof conversion cost is worth it, it’s critical to look beyond the invoice. This is an investment that saves you money every single month and protects you from rising energy costs in the future.
A well-maintained conservatory can certainly add value to your property — but only if it’s fit for purpose.
A draughty, noisy conservatory that’s only usable during certain seasons is unlikely to excite potential buyers - but a solid roof conservatory can add a five figure sum to your property value!
It’s not just about numbers.
A conservatory roof conversion can make your home more appealing to a broader range of buyers.
Families may see it as an ideal playroom or second lounge. Remote workers might envision a peaceful home office. Retirees could see it as a sun-filled reading room or hobby space. What was once a seasonal room becomes an integral part of the home.
And importantly, a solid roof helps the conservatory blend visually with the rest of the house, giving your property a more cohesive and contemporary aesthetic.
We’ve already covered how the average conservatory roof conversion cost falls between between £7,000 and £20,000,, depending on the project’s scale and specifications. But what exactly drives those numbers?
Here’s a closer look at the key elements that determine pricing — and how Projects4Roofing ensures you get maximum value for your investment.
In short - yes!
One of the biggest benefits of conservatory roof conversion is the dramatic improvement in thermal performance.
If your current conservatory is only usable for three or four months of the year due to extreme temperatures, a solid insulated roof could change that completely.
The Guardian Warm Roof system, for example, includes layers of insulation, breathable membranes, and internal plasterboard finishes — all designed to create a thermally efficient barrier between your living space and the outside elements
With a U-value of just 0.15 W/m²K, the roof traps heat inside during winter and reflects solar radiation in the summer. This means you can enjoy your conservatory in January without plugging in multiple electric heaters, and still feel comfortable in July without resorting to noisy fans.
What’s more, insulating your conservatory roof helps regulate temperatures in adjacent rooms, too. If your conservatory shares a wall with a kitchen or lounge, improving the conservatory roof insulation reduces the overall strain on your heating and cooling systems, further cutting your energy usage.
The bottom line? If you’ve been wondering, “Does putting a roof on a conservatory make it warmer?”, the answer is a resounding yes.
And not just warmer in winter, but more stable, consistent, and comfortable all year long.
