Guardian Warm Roof Plymouth

The Guardian Warm Roof System has been specifically designed to weigh no more than a glazed roof. Its structural performance is fully tested and approved by industry experts. Unlike some conversion systems, which only overclad the existing roof that was never designed to carry additional weight in the first place, the Guardian roof has been engineered to replace the entire existing roof.

Contemporary conservatories have reinforcing posts to take the weight of glazed roofs. However, those built before 1996 may not have sufficient support. The Guardian survey will determine the suitability and, where required, will provide a structural solution to support the Guardian Warm Roof for your Plymouth conservatory.

The Guardian Warm Roof System has been subjected to independent thermal analysis that takes into account the entire roof assembly, including cold bridging, to give a true U-value, as required by Building Regulations. Cold bridging has a major impact on U-value and, if not taken into account, will reduce thermal performance.

Many roof conversions state similar U-values or better. However, unless the entire assembly has been thermally tested, these are only theoretical. If in doubt, ask!

The Guardian Warm Roof is a ventilated roof system. Slots in the ring and ridge beams let air flow freely through the roof, allowing any moisture to exit. With many unproven roof conversions, moisture can form inside the roof, which causes staining and mould growth to the internal plasterboard. In turn, this leads to deterioration or even failure of the roof components.

After months of testing the Guardian Warm Roof with various UK materials, a superior lightweight aluminium frame was chosen due to its high-performance structural properties.

Many roof systems use timber, which weighs significantly more, putting additional stress on the existing conservatory walls. Additionally, timber is also prone to shrinkage and is often cut to size on-site. In contrast, the Guardian Warm Roof structural frame is manufactured and preassembled under quality controlled factory conditions.

A Guardian Warm Roof is typically priced in the mid-to-upper range of conservatory roof replacements in the UK, due to the fact that it’s a full insulated structural upgrade rather than just swapping panels.

Guardian Warm Roof prices can vary significantly, based on:

• Size & shape (Victorian, Edwardian, Lean to, etc.).
• Structural upgrades to support the heavier roof if you have an older conservatory.
• Tile choice & extras (e.g., skylights, bespoke finishes).
• Building Regulations approval.

Yes. Building Regulations consent is a legal requirement when converting a conservatory roof to a solid insulated roof system. As Guardian Certified Installers, we are able to access and partner with the LABC (Local Authority Building Control) Authority Scheme to manage this approval for you, so you’ll have nothing to worry about.

Thanks to the high-performance insulation and with building approval, the Guardian Warm Roof System may allow for the wall between your house and conservatory to be removed, providing the flexibility to extend and enlarge an existing kitchen, living room, or bedroom. Please let us know if that’s something you would like to consider.

The main disadvantages of a warm roof on a conservatory are as follows:

• Higher upfront cost – More expensive than replacing like-for-like polycarbonate or glass roofs due to added structure, insulation, and plastered ceiling.
• Loss of natural light – A solid tiled roof blocks most overhead daylight, so the room can feel darker, unless you add roof windows.
• Building Regulations – You’ll need Building Regulations approval because it effectively turns the conservatory into a permanent extension. However, we can get this for you.
• Less ‘conservatory feel’ – You lose the open, garden-room aesthetic; it becomes more like a standard room.

In short - you gain year-round usability and insulation, but trade off light, cost, and the traditional conservatory character.
