Available in uPVC, aluminium, and timber finishes, our installations comply with FENSA standards and come with comprehensive guarantees.
Conservatory Roofs
Guardian Warm Roofs transform conservatories into year-round living spaces with superior insulation and durability. Our installations replace outdated glass or polycarbonate roofs with lightweight, thermally-efficient composite systems. This upgrade improves comfort levels while preserving structural integrity and design aesthetics.

Engineered for maximum security and minimal maintenance, our composite doors feature reinforced frames and multi-point locking systems. Available in various styles and finishes, they provide enhanced thermal performance while complementing both modern and traditional property designs.
Carports
Custom-designed carports protect vehicles from weather damage while adding architectural interest to properties. Constructed using durable aluminium and glass elements, our solutions offer sleek aesthetics combined with functional protection for multiple vehicle types.

We went with Siesta as my sister used Siesta and said they were fantastic. We had a new guardian roof fitted and it made a huge difference to the conservatory.
