5 good reasons to choose the ultraframe conservatory glass roof replacement:
Thermally-Efficient Glass Roof
Our conservatory glass roof replacements are installed with chambered top caps as standard, providing structural strength and ensuring warmth even in the harshest weather conditions. The chambered structure of the Ultraframe conservatory glass roof also adds an extra layer of security, as these caps cannot be removed (unlike the traditional single-skin caps).
When you choose the Ultraframe Glass Roof for your home or business in Southeast England, you are investing in an energy-efficient, robust, and highly secure glass roof built and installed to the highest industry standards.
Improved Ventilation (without moisture buildup)
The Ultraframe Glass Roof also comes (as standard) with trickle vents, which provide a controlled, continuous flow of air to prevent moisture buildup and help regulate the temperature. This feature is especially important during the summer months when overheating is a potential concern.
Our approved Ultra installers will gladly answer any questions about how trickle vents work and guide you through the options for your new conservatory glass roof in Southeast England. Enjoy improved ventilation without sacrificing the comfort or temperature of your conservatory or commercial extension.
Secure & Leak-Proof Glass Roof
The built-in patented Speedlock system ensures your conservatory glass roof clicks into place easily and is adjustable to accommodate slight pitch variations. With the Speedlock system, every glazing bar fits snugly, attaching to the ridge to ensure no structural problems with your glass conservatory roof later.
Additionally, there are three layers of storm shield protection in the Speedlock hood, ensuring your conservatory glass roof replacement remains highly secure and leak-proof for years to come.
Our approved Ultraframe installers in your area fit durable glass conservatory roofs for both homes and commercial buildings across Southeast England.
Keeping the Glass in Place
The robust glazing stops, which come as standard with your glass conservatory roof, effortlessly hold the glass in place. You don’t need to worry about glazing panels readjusting and causing issues in your roof later down the line – the glazing stops provide a sturdier and stronger glass roof than any other conservatory glass roof on the market.
Our approved Ultra installers will guide you through everything you need to know about the Ultraframe glass roof and where we operate in Southeast England.
Bespoke Conservatory Glass Roofs
Add a touch of style with a decorative cornice to hide any unsightly guttering and a range of painted aluminium or foiled colours.

All of these details will be discussed in more detail during the conservatory glass roof design phase; you can even add timber finishes, super-insulated columns and pelmets to personalise your conservatory glass roof further.
Conservatory Glass Roof FAQs:
Natural Light, Comfort & Energy Efficiency
A conservatory glass roof is a modern roofing solution that uses high-performance glazed panels instead of polycarbonate. Glass roofs allow maximum natural light, improved insulation and a stylish finish that blends seamlessly with your home.
Glass roofs provide year-round comfort, better energy efficiency and clearer views. With modern coatings, they can reduce glare, block excess solar heat, and keep warmth inside during colder months. They also offer a quieter solution compared to older polycarbonate roofs.
Yes — our glass roofs are designed with double or triple glazing, low-E coatings and warm-edge spacers. They deliver excellent U-values, reducing heat loss while maintaining natural light, making your conservatory more energy-efficient and comfortable.
Yes — solar control glass helps manage heat by reflecting excess sunlight and reducing glare. This ensures your conservatory stays cooler in summer while still letting in natural light. We’ll recommend the best option based on your home’s orientation.
Many of our glass roofs come with self-cleaning glass, which uses a special coating that breaks down dirt and allows rainwater to wash it away. This keeps your roof cleaner for longer with minimal maintenance.
In most cases, replacing or upgrading a conservatory roof does not require planning permission as long as the structure remains the same. Exceptions may apply for listed buildings or conservation areas. We’ll confirm requirements during your survey.
The cost depends on size, glazing type, and specification. While glass roofs are more premium than polycarbonate, they offer long-term value through better comfort, durability and energy savings. We provide free, no-obligation quotes and offer finance options (subject to status).
Most glass conservatory roof installations take around 3–5 days, depending on the size and complexity of the project. We’ll confirm an accurate timeline during your quotation and aim to minimise disruption to your home.
Yes — upgrading to a high-performance glass roof can boost your home’s value, kerb appeal and usability. Buyers see it as a premium feature, particularly when it transforms a conservatory into a comfortable, year-round living space.
All installations include a 10-year insurance-backed guarantee, plus manufacturer warranties on frames and glazing. Installations are also FENSA-registered where applicable, ensuring compliance with Building Regulations.
