Warm roof systems from Range Windows revolutionize conservatory living, turning an uncomfortable space into a comfortable, energy-efficient room you can enjoy every day of the year.
Advanced Insulation Technology
Multiple layers of high-performance insulation boards sandwiched between internal and external structural panels achieve U-values as low as 0.15 W/m²K.
Exceptional Acoustic Performance
Dense insulation layers significantly reduce external noise from rain, hail, and traffic, creating a peaceful indoor environment.
Quick Installation
Our experienced installers can typically complete a warm roof installation in just 2-3 days with minimal disruption to your daily routine.
A warm roof system replaces a conservatory's existing glass or polycarbonate roof with a fully insulated solid roof structure, achieving U-values as low as 0.15 W/m²K. It includes an internal plastered ceiling that gives the room a genuine house extension feel, making your conservatory warm in winter, cool in summer, and quiet year-round.
Warm roof installation in Sunderland typically costs between £8,000 and £15,000 depending on the size of the conservatory, the roof pitch, and the chosen external finish (tiles, slate, or flat roof covering). Range Windows provides free home surveys and no-obligation quotes across Tyne and Wear, with finance options available.
A typical warm roof installation takes 2 to 3 days, depending on the size and complexity of the conservatory. Our experienced installation team work efficiently to minimise disruption, and most projects are completed with the conservatory habitable again within the same week.
The majority of conservatories in Sunderland and across Tyne and Wear are suitable for a warm roof upgrade. Our surveyor will assess the existing frame, foundations, and structural walls to confirm suitability before any work is committed to. In some cases, minor structural reinforcement may be recommended.
In most cases, replacing a conservatory roof with a warm roof system falls within permitted development rights and does not require planning permission, provided the conservatory itself was built under permitted development. Properties in conservation areas or listed buildings should check with Sunderland City Council before proceeding.
Glass and polycarbonate conservatory roofs are notoriously uncomfortable — too hot in summer, too cold in winter, and very noisy in heavy rain. A warm roof solves all three problems: it insulates to 0.15 W/m²K for year-round comfort, dramatically reduces noise, and creates a plastered internal ceiling that makes the conservatory feel like a genuine room rather than a temporary extension.

Fantastic experience with Lee from Range Windows. Prompt efficient service, windows swiftly measured up and date of installation agreed. Call on the day of installation to confirm the time and Lee arrived as agreed. Fab installation and exceptionally happy with the product. Will definitely recommend.

Had a new door fitted by Range Windows and Doors today, door looks amazing and service was brilliant. Everything was all cleaned up after the job was finished too which was a bonus. Highly recommended.

Definitely recommend this company! Service is 5 star, they try to help any way they can. Fitting me in to fit a low profile door so my wheelchair could get in my new home. The door is easy to work, draft free and feels very secure and solid. A very caring genuine company which is hard to find nowadays.

Adam and Brad came early, on time and got to work straight away. They worked hard, fitting 3 new bedroom windows then a back door — all finished in the day. Every item was installed well. They cleaned up everything inside and out, taking all rubbish away with them. Thank you for your good work.

Within a day Adam came to the house for a free quote — no pressure, no rush. Very professional and we chose this company just from how Adam represented them. Lee measured everything up within days, giving honest advice where other companies were saying to replace everything. Outstanding service.

I couldn't recommend these guys enough! Service was spot on start to finish. Lee and the guys are so knowledgeable about their products, even dropping off brochures so I could make a decision in my own time. No pressured sales, just down to earth people. Adam and Brad fitted the door — so professional.
