Ensuring your peace of mind
Will my conservatory be able to take the weight of the Guardian Warm Roof?
The Guardian Warm Roof System has been specifically designed to weigh no more than a glazed roof and is fully tested and approved by industry experts for it’s structural performance. The Guardian roof is designed and engineered to replace the entire existing roof. Some conversion systems only overclad the existing roof which was never designed to carry additional weight.
Conservatories have reinforcing posts to take the weight of glazed roofs. Conservatories 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.
Why is the Guardian Warm Roof structural frame made from aluminium?
After months of testing the Guardian Warm Roof with various 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. Timber is also prone to shrinkage and is often cut to size on-site unlike the Guardian Warm Roof structural frame which is manufactured and preassembled under quality controlled factory conditions
How can Guardian guarantee the thermal performance of the warm roof system?
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, but these are theoretical unless the entire assembly has been thermally tested. If in doubt, ask.
I’ve read reports of condensation and mould with these types of roof – how is Guardian different?
The Guardian Warm Roof is a ventilated roof system. Slots in the ring and ridge beams allow air to flow freely through the roof allowing any moisture to exit. With many unproven roof conversions, moisture can form inside the roof causing staining and mould growth to the internal plasterboard, leading to deterioration or even failure of the roof components.
Will I need to apply for Building Regulations approval for the new roof?
Yes. Building Regulations consent is a legal requirement when converting a conservatory roof to a solid insulated roof system. All Guardian Certified Installers are able to access and partner with the LABC (Local Authority Building Control) Authority Scheme to manage this approval for you.
Due to the high-performance insulation and with building approval, the Guardian Warm Roof System, may allow the removal of the wall between the house and conservatory, providing the flexibility to extend and enlarge an existing kitchen, living room or bedroom.
System benefits
Rapid installation
Installed by one of our Guardian Certified Installers, the whole conservatory roof installation only takes a few days and is completed with minimum disruption to your home.
Reduces noise & sun glare
Your new room will be quiet and comfortable all year round as any rain / weather noise will be eliminated. The Guardian roof also significantly reduces sun glare, which in turn prevents sun bleaching to fixtures and fittings, removing the need to fit blinds to the windows of your conservatory.
Engineered for quality
Each Guardian roof is engineered precisely to your individual requirements and pre-assembled under controlled factory conditions to ensure the highest quality before delivery to site.
Temperature control
A Guardian Warm Roof regulates the temperature of your conservatory to ensure it’s a pleasant temperature whatever the season. The high-performance insulation guarantees lifetime thermal performance, ensuring your room is economical to heat.
Superior energy efficiency
It has been independently proven that a Guardian Warm Roof can save you money on your energy bills, using high performance insulation that achieves a superior U-value of only 0.15 W/m2K.
Complete peace of mind
The Guardian Warm Roof was the first LABC partnered conservatory solid roof system. For peace of mind, all of our Guardian Certified Installers are able to access and partner with the LABC Authority Scheme to maintain building control compliance.
“With Building Control approval, internal dividing doors or walls can be removed to provide an open-plan living space.”
