Roof Lanterns
A made-to-measure aluminium roof lantern for flat roof extensions and garden rooms. Ultra-slim 60mm ridge, self-cleaning glass as standard, available in 5 days.
Design Choices
A roof lantern is more spec-led than a typical window or door, so the key choices are frame finish, glass type, vent control, and how fast the made-to-measure unit needs to be fabricated.
The standard roof-lantern palette covers the most common grey, black, and white routes, with custom colours available when the lantern needs to tie into the roof finish or interior scheme.
Custom RAL colours available to order
Can be matched to the lantern kerb, roof finish, or interior palette
Powder-coated aluminium finish keeps maintenance low
Stock colours support the fastest lead times. Custom RAL colours are confirmed once glazing, vent, and fabrication requirements are signed off.
Roof-lantern glazing is usually chosen around how much daylight, glare control, and insulation the room needs rather than decoration alone.
Clear glazing is the cleanest daylight route and comes with the self-cleaning, argon-filled, warm-edge specification that makes the Maxi lantern range practical in everyday use.
Blue, neutral grey, and bronze tint routes help manage glare and solar gain on brighter roof orientations without losing the clean lantern look.
The lantern can be configured around either double or triple-glazed units depending on thermal targets, opening size, and the wider extension brief.
Self-cleaning glass, argon filling, and warm-edge spacers remain standard across the glazing options rather than premium add-ons.
Vent choice matters most in kitchen extensions and warmer rooms where the lantern is being asked to help with passive cooling as well as daylight.
A manual vent is the simplest route where the lantern is accessible and the client wants fresh air without adding automation.
Electric operation suits higher lanterns and larger kitchen extensions where regular ventilation is wanted without manual reaching.
Rain-sensor control helps protect the room if the vent is left open and the weather turns, which is useful on changeable days and occupied family rooms.
A thermostatically controlled vent opens and closes around room temperature, helping to manage summer heat build-up in glazed extensions.
The lantern is fabricated around the exact roof opening rather than pulled from a fixed stock matrix, so sizing and lead time form part of the design conversation early.
Every Maxi-Hipped lantern is built to the exact roof opening so the final lantern proportions and kerb fit are tuned to the project rather than forced into a stock size.
Express fabrication keeps bespoke sizing commercially realistic on live extension work, helping the lantern stay on programme without dropping to a generic stock unit.
Where the project is being coordinated closely with builders or roof contractors, premium service options such as faster kit supply can also be discussed at survey stage.
Bespoke sizing rather than off-the-shelf retail modules
Fabrication confirmed after survey and opening check
Lead time varies with colour, glazing, and vent specification

If this looks like the right fit, we can survey the opening, confirm the specification, and price it properly for your home with no obligation.
The Maxi-Hipped Roof Lantern is the raised architectural option for flat roof extensions and garden rooms where you want more visual presence than a flush rooflight. Built by our premium aluminium manufacturer using ultra-slim aluminium profiles with a 60mm ridge beam, every lantern is made to your exact dimensions in five days on the express service. Self-cleaning, argon-filled glass and warm-edge spacers come as standard — not as an upgrade.

Core Information
The main performance, specification, and installation details that shape how this aluminium range works in practice.
Best For
Flat roof extensions where a raised lantern form is wanted
Garden rooms and kitchen extensions needing stronger overhead light
Projects where made-to-measure sizing and fast manufacture both matter
Thermally efficient aluminium framing sits behind the hipped lantern design, with the final glass and vent specification selected around orientation, room use, and ventilation needs. That keeps the performance discussion tied to the actual lantern specification rather than placeholder roof-glazing copy.
Hipped roof lanterns can be tailored around colour, glazing, and vent options. Custom exterior colours and optional interior colour packs help the lantern sit cleanly with both the room interior and the external roof finish. Self-cleaning glass and vent upgrades can also be built in at quote stage.
All CII roof lantern installations carry our 10-year installation guarantee, with the full survey, fit, and handover managed by CII.
Roof Lantern Design
This range is built around a more architectural raised lantern form, with the specification tailored to the opening rather than treated as a generic glazed roof add-on.
A raised hipped lantern creates a more architectural roof form for clients who want stronger visual presence from above.
Sizing is built around the project rather than limited to a tight off-the-shelf retail matrix.
Custom exterior colours and interior colour packs give more finish flexibility than a basic stock lantern.
Self-cleaning glass and vent options can be built into the final lantern specification where the room layout calls for them.
