Guardian Warm Roof
Conservatory Roof Replacement
The Guardian Warm Roof is the UK’s leading solid conservatory roof replacement system, perfect for homeowners in Essex and Suffolk looking to transform their conservatory into a year-round living space.
Unlike simple cladding systems, the Guardian Warm Roof is a complete replacement roof. It’s lightweight, fully insulated, and designed to weigh no more than a glass roof. Every system is rigorously tested and approved for strength, safety, and thermal performance.
With a Guardian Warm Roof, you’ll enjoy:
- Year-round comfort – warm in winter, cool in summer
- Energy efficiency – reducing heating bills
- Customisation – choose from a range of tile and slate colours, plus options such as Velux windows, rooflights, or integrated downlights
As a Building Regulations–approved roof system, the Guardian Warm Roof ensures compliance, giving you peace of mind. Our expert team handle the entire process, from design to installation, guiding you through every step.



Thermal Lantern Roof Extensions
For homeowners in Essex and Suffolk who want to maximise light while keeping heat under control, a Thermal Lantern Roof is the perfect solution. Its sleek, modern design makes it ideal for new glass extensions, open-plan kitchens, or brightening up darker areas of your home.
With advanced thermal technology, a lantern roof ensures:
- A bright, airy feel without drafts or cold spots
- Warmth in winter and a cooler space in summer
- A stunning architectural feature that adds value to your property
