Aluminium Roof Lanterns in Surrey
Bespoke aluminium roof lanterns that flood your home with natural light. Designed to impress and built to last, installed by Surrey's trusted glazing specialists at Ensure Windows.
An Architectural Feature That Transforms Your Home
A roof lantern is a raised glazed structure installed into a flat or low-pitch roof, designed to draw natural light deep into a room while creating a dramatic architectural centrepiece. Unlike flat rooflights, a lantern rises above the roof plane, creating internal height and a beautiful visual feature from both inside and outside the home.
Our aluminium roof lanterns are manufactured using slim thermally broken frames, allowing for maximum glazing area and outstanding views of the sky. They are available in any RAL colour, any size, and a range of pitch angles to suit your roof and aesthetic preference.
Whether you are building a new kitchen extension in Caterham, adding an orangery in Redhill, or brightening a dark hallway in Coulsdon, an Ensure Windows roof lantern will transform your space in a way that no other glazing solution can.
Six Reasons Surrey Homeowners Love Roof Lanterns
Flood Rooms with Daylight
A roof lantern can increase natural light in a room by up to 40%, dramatically improving ambiance and reducing artificial lighting costs throughout the day.
Adds Property Value
A quality aluminium roof lantern is a desirable architectural feature that adds kerb appeal and tangible value to your home in Surrey's competitive property market.
Year-Round Thermal Comfort
Thermally broken aluminium frames and high-performance glazing units keep heat in during winter and prevent overheating in summer, unlike older-style skylights.
Stunning Focal Point
A beautifully designed roof lantern instantly becomes the centrepiece of any room — an architectural statement that creates a sense of space and drama.
Self-Cleaning Glass Option
Optionally specify self-cleaning glass which uses UV light and rain to break down and wash away dirt — keeping your lantern crystal clear with minimal effort.
Fully Bespoke Sizes
Every roof lantern we install is manufactured to your exact roof opening dimensions. From compact 1m x 1m units to expansive 4m x 2m statement pieces.
Where Can a Roof Lantern Be Installed?
Kitchen Extensions
The single most popular location for roof lanterns. A lantern over your kitchen-diner extension creates a naturally lit, warm social space that becomes the heart of the home.
Orangeries
An orangery without a roof lantern is just a room. Adding a lantern introduces the architectural drama and natural light that defines a true orangery and sets it apart.
Flat Roof Extensions
Flat roofs can feel dark and enclosed. A roof lantern solves this completely, drawing natural light deep into the space without taking up any wall area.
Hallways & Landings
Dark interior hallways and landings are transformed by a well-placed roof lantern — brightening the entire central core of your home naturally and beautifully.

Pitch Angle Guide
The pitch angle of your roof lantern affects both the internal volume and the external profile. We recommend angles based on your room size and aesthetic preference.
Sleek, minimal profile. Suits contemporary flat-roof extensions perfectly. Maximum external discretion.
The most common pitch. Excellent balance of internal height, external aesthetics, and drainage performance.
