Our lantern roof conservatory replacement service works across domestic and commercial properties. We combine Guardian's industry-leading warm roof technology with professional installation expertise to create stunning rooms that add genuine value.
Lantern roofs are traditionally fitted to orangeries and serve as premium conservatory roof replacement options. The design features large glazed panels that slope upwards to form a raised central structure, creating architectural interest that floods rooms with natural light.
Lantern conservatory roofs add height and visual impact while maintaining structural integrity. This elevated design has grown significantly in popularity over the past decade, particularly in larger conservatories and orangery-style extensions where homeowners prioritise natural light and architectural impact.
Aluminium frames allow for larger panes of glass due to their strength and slim sightlines. We install modern systems that combine traditional aesthetics with contemporary materials and excellent insulation for year round comfort.


Lantern roofs allow generous levels of natural light to enter the room. The elevated central structure captures light from above whilst surrounding roof slopes gather illumination from multiple angles, creating a bright and open living space.
The design creates an airy atmosphere that makes rooms feel more spacious. This transforms dark conservatories into stunning living areas. We help you maximise natural light through careful planning of glazing positions whilst controlling heat and glare through advanced technology.
