Roof Lanterns & Skylights

Learn more about roof lanterns & skylights

Roof lanterns and skylights maximise natural light entering a room while preventing heat loss across open-plan living areas. 

A roof lantern is a glazed, raised structure fitted over an opening in a flat roof to bring natural light down into the space below. They rise in a pitched or pyramid shape, so daylight enters from several angles throughout the day. Skylights, or flat rooflights, are flush roof windows that sit level with the roof. 

Typical uses

• Flat roof extensions: Flooding ground-floor kitchen extensions, dining spaces, and garden rooms with natural sunlight.

• Property renovations: Replacing outdated flat roof lights to boost energy efficiency and refresh internal aesthetics.

• Commercial and office spaces: Illuminating internal corridors, reception areas, and meeting rooms lacking side windows.

• Conservatories and sunrooms: Creating architectural ceiling features.

How to choose the right roof lanterns & skylights

• Measuring internal vs. external dimensions: Always confirm whether your chosen roof light measures to the external weathered kerb size or the internal plasterboard opening to avoid miscalculating dimensions.

• Thermal efficiency and solar control: Choose self-cleaning, solar-reflective glass for south-facing extensions to prevent summer overheating. Ensure overall U-values satisfy Part L building regulations for domestic additions.

• Frame material and longevity: Select powder-coated aluminium frames for superior strength, slim profiles, and low maintenance over traditional PVCu alternatives.

Before you order

• Take accurate measurements of the opening width, length and the kerb height the lantern will sit on, and double-check against the product specifications.

• Confirm the roof type and that the structural opening is correctly framed and loadbearing for the unit you're fitting.

• Plan the upstand or kerb detail and the flashing, as weatherproofing around the perimeter is where most leaks start.

• Check the fixing method and that the opening aligns with the rafters or trusses so the lantern is fully supported.
