A More Affordable Way to Replace Your Conservatory Roof

25th September 2026

Replacing an old conservatory roof can make a huge difference to how often you use the space, but it doesn't always need to mean investing in a traditional solid or tiled replacement roof.

EYG's Thermo Roof offers a more affordable alternative, using lightweight insulated PVC roof panels with optional glass sections to help create a more comfortable conservatory while retaining plenty of natural light.

For one EYG customer, replacing their old fully glazed conservatory roof with a Thermo Roof transformed a room they had found practically unusable into a space they could enjoy throughout the year.

An alternative to a traditional replacement conservatory roof

The homeowners had previously chosen a fully glazed roof for their conservatory, but soon found that the room became unbearably hot during warmer weather.

During the colder months, they faced the opposite problem. The conservatory was difficult to keep warm and condensation regularly formed inside.

Rather than replacing the entire conservatory or choosing a more substantial traditional solid roof system, they contacted EYG to explore their conservatory roof replacement options.

They chose our Thermo Roof, an insulated conservatory roof system which combines lightweight PVC roof panels with strategically positioned glass sections.

This allows homeowners to improve the thermal performance of their conservatory without completely losing the bright, open feel that made them choose a conservatory in the first place.

A more affordable conservatory roof replacement

Traditional tiled and solid conservatory roof replacements can provide excellent thermal performance, but they can also represent a significant investment.

The EYG Thermo Roof provides another option for homeowners who want to improve an existing conservatory without moving to a full traditional replacement roof.

Its lightweight insulated PVC panels can replace large areas of existing glazing, helping reduce heat transfer through the roof while existing or new glass sections can be incorporated into the design to maintain natural light.

That makes the Thermo Roof particularly suited to homeowners whose main priority is making an existing conservatory more comfortable and usable without unnecessarily replacing the complete structure.

From an uncomfortable conservatory to a usable living space

Before the Thermo Roof was installed, the homeowners said the temperature inside their conservatory made it difficult to use for large parts of the year.

During summer, the glazed roof allowed the room to become extremely warm.

In winter, they experienced cold temperatures and significant condensation.

The difference following the replacement roof installation was immediately noticeable.

“We’ve been thrilled with this new roof. It was unbearable in the conservatory in summer before we had it changed as it was so hot. However, with the new roof in place, we’ve been able to sit comfortably in the room, have our meals in here, and enjoy the space,” said the customer.

“The other problem with the old glazed roof was the condensation which built up in the winter months. We’d find a puddle on the floor in the mornings, and it was so cold that we needed the heater on full 24 hours a day, and it still wasn’t warm enough.”

Insulated conservatory roof panels with natural light

One of the biggest advantages of the Thermo Roof is the ability to combine insulated roof panels with glass.

Many homeowners enjoy the amount of daylight a traditional conservatory provides and understandably don't want to lose that completely when replacing the roof.

With a Thermo Roof, the balance of PVC panels and glazing can be incorporated into the roof design, giving homeowners the benefits of additional insulation while maintaining natural light.

The specialist insulated panels used within the Thermo Roof have a U-value of 0.65, helping reduce heat transfer through the roof compared with traditional glazed sections.

The lightweight panels are also made from 100% recyclable material and are designed to help reduce some of the condensation issues commonly associated with older conservatory roofs.

Making more of an existing conservatory

John Waugh, Domestic Sales and Marketing Director at EYG, said:

“Conservatories remain a very popular home improvement, but the roof can make a huge difference to how comfortable the room feels throughout the year.

“For homeowners who already have a good conservatory structure, completely replacing it isn't always necessary.

“Our Thermo Roof gives customers another option. Insulated panels can replace much of the existing glazed roof while glass sections can still be incorporated where customers want to retain natural light.

“It provides a more affordable alternative to a traditional replacement roof for customers who simply want to make better use of the conservatory they already have.

“We are delighted that the customer is happy with the result and can now enjoy much more use from their conservatory.”

Installed in just three days

Replacing a conservatory roof doesn't necessarily mean weeks of disruption either.

For this project, the EYG installation team removed and disposed of the customer's existing glazed roof and completed the Thermo Roof installation in just three days.

The homeowners were particularly impressed with the installation team.

“The fitters were here at 8.30am every morning and they worked solidly to get the job done, hardly taking a break, other than the odd cup of tea.

“It was all done quickly and to a high quality. One said he had been fitting for EYG for 30 years, so that was very reassuring to hear too.

“We have all our windows and doors from EYG, and we are very happy with them. When we had the conservatory built, we went with another firm as they were cheaper, but we’ve ended up having to come to EYG to make it as we want it to be in the end.”

Is your conservatory too hot in summer and too cold in winter?

If an older glass or polycarbonate conservatory roof is making your conservatory difficult to use, replacing the roof could dramatically change how you use the room.

A Thermo Roof offers an affordable way to upgrade an existing conservatory using insulated conservatory roof panels combined with glass, helping improve year-round comfort without automatically moving to a traditional tiled or solid replacement roof.

EYG Thermo Roofs also come with a 10-year warranty, giving you additional peace of mind.
