Guardian Warm Roofs –
The Ultimate Conservatory Roof Upgrade
Upgrade Your Conservatory into a Year-Round Living Space
The Roof is a fully insulated, tiled conservatory roof system designed to replace old glass or polycarbonate roofs and transform your conservatory into an extension-like room you can enjoy in every season. It solves the classic conservatory problem of being too hot in summer and too cold in winter by providing a comfortable, consistent indoor temperature all year round. Homeowners report that with a Guardian Warm Roof, their conservatory becomes an integral part of the home, quiet, cosy in winter, and pleasantly cool in summer.
Beyond comfort, the Guardian roof dramatically improves your conservatory’s appearance and value, blending in with your home’s architecture so it looks like a natural extension of the house rather than an add-on.
Engineered for Performance
The Warm Roof system is a lightweight yet robust construction that’s been purpose-built for conservatories. Each roof is custom-manufactured to fit any conservatory shape and is assembled using a strong but lightweight aluminum frame. This clever design ensures the new solid roof often weighs no more than the original glazed roof, so in most cases, the existing conservatory structure can support it without extra reinforcement.
It was the first replacement conservatory roof approved by the LABC (Local Authority Building Control), meaning it meets building regulations and has been independently tested for structural and thermal performance. Every Roof installed by an approved installer comes with a comprehensive 10-year guarantee, giving you peace of mind about its quality and durability.
Energy Efficiency & Insulation
High-Performance Thermal Insulation
The Guardian Warm Roof is built as a “warm roof” system with multiple layers of insulation that dramatically improve thermal performance. The roof’s composition includes a pre-engineered frame, two layers of rigid insulating board, insulated internal plasterboard, exterior-grade plywood, and a ventilated waterproof membrane, all finished with your choice of tiles.
This advanced design achieves an impressive U-value as low as 0.18 W/m²K (0.15 W/m²K in Scottish installations), far outperforming typical glass or polycarbonate roofs. (For context, lower U-values mean better insulation and less heat loss.) In practical terms, the Guardian roof keeps the heat inside during winter and prevents intense sun from overheating the space in summer. Homeowners often find they no longer need to crank up the heating, resulting in lower energy bills over the life of the roof.
The system is designed to meet or exceed the latest building regulation targets for insulation, so you can be confident your conservatory will be energy-efficient and cost-effective to run.
Year-Round Comfort & Quiet
With a Guardian Warm Roof, your conservatory maintains a comfortable ambient temperature all year round, effectively turning it into a true living room rather than a seasonal space. The superior insulation not only stabilizes the temperature but also dampens noise from rain and outside elements.
Unlike old polycarbonate roofs that rattle and amplify rain noise, the solid tiled Guardian roof greatly reduces noise by up to 30 decibels in many cases. This means you can relax, watch TV, or entertain in your conservatory without the distraction of heavy rain drumming overhead.
The roof system is also fully ventilated and condensation-resistant by design, with built-in air flow channels to dispel moisture. This eliminates the cold draughts and condensation issues that plague poorly insulated roofs. In short, Guardian’s efficient insulation ensures your conservatory is warm and cosy in winter, cool and airy in summer, and quiet and dry through any weather – providing comfort and enjoyment 365 days a year.
Conservatory Styles & Compatibility
Built to Fit Any Conservatory Style
One of the major advantages of the this system is its versatility, it can be tailor-made to replace the roof on virtually any conservatory type or shape. Whether you have a classic Victorian, a spacious Edwardian, a Lean-to sunroom, a lofty Gable-End design, a P-shaped/combination layout, or even a custom bespoke conservatory, the Guardian system can be adapted to fit perfectly.
The replacement roof is custom fabricated to match your conservatory’s exact dimensions and configuration, ensuring a precise fit and an efficient installation. Even unusual or non-standard designs can be accommodated, the Guardian roof’s modular construction makes it flexible for L-shapes, T-shapes, or any unique layout.
Seamless Integration
Guardian Warm Roof conversions are designed to work with your existing conservatory framework, so you typically retain your original windows, doors, and base while simply swapping out the roof. This means you can upgrade to a solid roof without the cost or hassle of rebuilding the entire structure.
The result is a conservatory that not only looks brand new but also functions like a conventional home extension. With building control approval, some homeowners even choose to open up the wall between the house and conservatory after installing a Guardian roof, effectively uniting the spaces into one large room.
Even if you keep the rooms separate, the finished look, inside and out, will make your conservatory feel like a natural part of your home. Importantly, the Guardian roof’s external profile and pitch can be configured to match your house roof line, maintaining your home’s character.
Customization Options
Tailored Exterior Finishes – Tiles, Slates & Colors
The system offers a wide range of finishing options so you can personalize the look to suit your home’s style. You can choose from different lightweight roofing materials that replicate the appearance of traditional tiles or slates, including:
