A pyramid rooflight is a raised, four-sided glazed unit, also known as a roof lantern or pyramid light, that adds height and architectural impact while flooding a room with daylight. Unlike a flat skylight, it rises into a pyramid shape that becomes a striking overhead feature. GLRE’s pyramid rooflight is a pre-assembled unit from £1,406.40 including VAT, engineered to mount directly onto flat roofs with a 5 to 15 degree pitch. This guide explains what pyramid rooflights are, how they differ from flat glass, where they work best, the sizes available and what to look for before you buy.
A pyramid rooflight is a fixed glazed unit with four sloping glass faces that meet at a central point, forming a pyramid. Its architectural design adds height and maximises light transmission, creating a stunning visual impact from both inside and outside the building. It mounts directly onto a flat roof with a gentle 5 to 15 degree pitch.
The terms pyramid rooflight, roof lantern, lantern rooflight and pyramid light are often used to describe the same product, which is why you will see GLRE list this unit under both “pyramid rooflights” and “roof lanterns”. Whichever term you use, the defining feature is the raised, contemporary pyramid form that elevates a space rather than sitting flush with the roofline.
The main difference is profile and effect. A flat glass rooflight sits low and flat for a minimal, modern sightline, while a pyramid rooflight rises into a raised lantern that adds volume, height and a clear architectural focal point overhead.
You would choose a flat glass rooflight when you want the cleanest, most understated look at a lower starting price, which suits contemporary extensions and simple flat roofs. You would choose a pyramid rooflight, or roof lantern, when you want a showpiece that draws the eye upward, adds a sense of grandeur and suits period or feature-led interiors. Both use the same quality glazing and enhanced options, so the decision comes down to the look and the impact you want.
Pyramid rooflights and roof lanterns work anywhere a raised glazed feature can lift a space, both in homes and in commercial buildings. Because they add height as well as light, they are popular where an overhead centrepiece is wanted.
GLRE pyramid rooflights are available in five standard sizes, from 900 x 900mm up to 2000 x 1000mm, and a bespoke made-to-measure service covers dimensions beyond the standard range. The table below shows each size and a suggested application.
| Size (mm) | Suggested Application |
|---|---|
| 900 x 900 | Hallways, entrance porches and compact rooms |
| 1000 x 1000 | Home offices, snugs and smaller kitchens |
| 1500 x 1000 | Kitchen-diners and mid-sized extensions |
| 1500 x 1500 | Open-plan living areas and feature entrance halls |
| 2000 x 1000 | Large extensions and commercial reception spaces |
As with any rooflight, fitting a pyramid rooflight into a flat roof usually needs to comply with the relevant Building Regulations, even where planning permission is not required. Because a lantern is a raised unit, structure is an especially important consideration. Official guidance is set out in the Approved Documents on GOV.UK.
Requirements vary by project, so confirm the details with your builder, architect or local building control before you order.
A pyramid rooflight is supplied pre-assembled and mounts onto an upstand on your flat roof, following the same core method as a flat glass unit but with extra attention to pitch. GLRE does not build upstands but can recommend a local contractor. The typical steps are below.
GLRE offers the same two enhanced protection upgrades on pyramid rooflights as on its flat glass rooflights, added as optional extras when you order.
Before ordering aluminium and glass roof lanterns, work through a short checklist so the unit suits your opening, your roof and your budget.
