The Ultraroof system seamlessly blends the robust thermal performance of a solid extension with the bright, airy feel of a traditional conservatory.

Many homeowners continually struggle with the classic UK weather dilemma: traditional polycarbonate conservatory roofs are far too freezing in the winter and unbearably hot in the summer. Conversely, completely solid timber-and-slate roofs are incredibly heavy and can frequently plunge the adjoining living room into darkness.

Ultraroof elegantly resolves this issue. Engineered by conservatory specialists Ultraframe, it represents the most advanced lightweight tiled roofing system available. It provides the highly authentic exterior aesthetic of a traditional extension, whilst delivering incredible, modern thermal performance.

2. What Exactly is Ultraroof?

Ultraroof is a precision-engineered, pre-manufactured solid roof. Unlike a traditional extension roof that requires complex timber cutting and battening on site, the Ultraroof is perfectly fabricated to your exact dimensions in the factory.

This intelligent design ensures that the entire structure can be made watertight in approximately 6 hours, meaning significantly less mess and disruption at your home.

3. Authentic Tiled Finishes & Colours

The exterior of the roof can be beautifully tailored to match your existing property roofline using authentic lightweight polymer tiles. Whether you reside in a heritage property in Winchester or a modern new build in Basingstoke, you can perfectly blend your new extension with the existing architecture.

5. Key Structural Benefits & Specifications

When searching for lightweight tiled conservatory roof replacements in Hampshire, performance is critical. Because the Ultraroof was explicitly designed by conservatory specialists, it addresses every common failure point of traditional roofing methods.

Feature Technical Benefit
The Lightest System Weighing only 38kg/m², it is the lightest tiled conservatory roof on the market. This guarantees it can safely sit on your existing uPVC window frames without requiring new brick pillars or foundations.
Unrivalled Strength Utilising NASA satellite data for wind and snow loads, the fully insulated 380mm structural beam can span up to 4 metres completely unsupported. This is perfect for homeowners wanting expansive bi-fold doors.
Thermal Efficiency It represents a true “warm roof” system with absolutely no cold bridging. It achieves an Ultraroof thermal efficiency U-Value of 0.15 W/(m²K) as standard, with the option to reduce this to an incredible 0.12 W/(m²K).
Fire Safety Unlike cheaper alternatives, the complete, assembled Ultraroof structure was rigorously fire tested by Warringtonfire, officially achieving a B-roof rating according to EN 13501-5: 2016.

6. Ultraroof for New Extensions

While exceptionally popular for upgrading old conservatories, the Ultraroof is actively becoming the preferred choice for brand new home extensions across Andover and Salisbury.

Because the Ultraroof never requires an unsightly internal tie bar, you are guaranteed a beautifully uninterrupted, plastered vaulted ceiling.

Internally, the roof delivers a stunning sense of height and drama. The system includes an insulated internal pelmet as standard, providing the perfect architectural housing for modern recessed downlighters or hidden speakers. Furthermore, by seamlessly inserting full-length performance glass panels exactly where you want them, you can flood the new extension with natural light without the glare.

7. Frequently Asked Questions

Yes. If you are changing a translucent glass or polycarbonate roof to a solid tiled roof, Building Regulations approval is legally required to ensure structural safety. However, the Ultraroof system has been pre-approved by the MFA and Stroma, meaning the compliance process is highly streamlined. KJM Group securely handles this certification for you.

Not necessarily. Because the Ultraroof is incredibly lightweight (38kg/m²), it is specifically designed to sit safely upon most existing high-quality uPVC or aluminium window frames. Our expert surveyors will carefully assess the structural strength of your current frames to ensure they are fully capable of supporting the new roof.

The most important advice is to absolutely avoid “conservatory insulation companies” who simply staple foil and plasterboard directly beneath your old polycarbonate roof. This “wrap-over” method frequently traps condensation, causes severe structural stress, and poses a major fire risk. The only safe, compliant way to insulate is to physically remove the old roof entirely and replace it with a structurally tested solid roof like the Ultraroof.
