Tips from the experts at Lantern Superstore
Flat roof extensions have been popular for many years, as they are a smart way to add space and value to your home. Whether it’s a bright open-plan kitchen or a cosy family room, these spaces offer endless practicality and potential. But one common challenge homeowners face – how to bring in more light to a flat roof extension.
At Lantern Superstore, we specialise in flat roof lights and roof lanterns, designed specifically for flat roof properties. Their large glass designs specifically transform darker spaces into bright, welcoming rooms. In this blog, we’ll explore how you can mazimise daylight and make your flat roof extension feel open and airy.

Ways to Bring In More Light
Choose A Roof Lantern For Instant Impact
If you’re serious about bringing natural light in, a roof lantern is one of the most effective ways to do so. Elevated using multiple panes, lanterns allow light to flood in the multiple angles, even during the lower sun of winter months. Plus, they create beautiful architectural feature from both the inside and outside of a flat roof extension.
By choosing a minimal frame design (like our Sovu Roof Lanterns here at Lantern Superstore), you’ll let in as much light as possible and keep the look sleek and contemporary.
Add A Flat Roof Light for Clean, Modern Natural Light
If you prefer a more understated look, or don’t want the height of a roof lantern, flat rooflights are a fantastic alternative. These glass structures sit flush with your roof and offer clear, unobstructed views of the sky. They’re ideal for modern extensions or rooms where you want the clean ceiling line, but still crave natural daylight.
At Lantern Superstore, our flat rooflights are known for flooding a living space with natural light whilst also providing excellent thermal efficiency, so you won’t have to trade warmth for light. You can also create modern designs with multiple rooflights to control light levels around different areas of your flat roof extension.
Maximise Wall Space with Glazing
Don’t stop at the roof to introduce natural light – vertical surfaces are also a great way to encourage direct sunlight into your living space. Adding bifold doors, large windows or sliding glass doors are a great way to use the exisiting space and maximise light coming in from all angles. Large glass panels can make all the difference in your extension – giving it a spacious feel. Plus, many modern design options such as those at UK Doors Online, have multiple choices to make the best use of your existing space.

When designing your new extension, think about the current space, and where the light comes into the area. You can use this to plan where glazed units may be beneficial, making it not only a brighter space, but more cost effective by reducing the need for artificial lighting.
Keep Interiors Light & Reflective
It’s not always about how light enters the space, but how it moves around once it’s in. Reflective surfaces like light-coloured walls, high-gloss kitchen units, and mirrors can bounce natural light deeper into the room. Think of your style and decor choices as part of your lighting opportunities.
Combine Flat Rooflights
Want to take it up a notch? Maximise the light into your flat roof extension by combining multiple flat roof lights and roof lanterns of different shapes and sizes onto your flat or existing roof to create more glass for the light to shine through.
By adding multiple flat roof windows over central spaces, you give both directional and ambient light throughout the day, making your home stunning from every angle. It’s also a clever way to balance statement design with practicality.
Factors to Consider
When making investments to maximise light into your property, it’s important to consider multiple factors that may influence your decision. These factors may require additional steps to be taken before adding home improvement products to a flat roof extension.
Planning Permission
In some instances, planning permission may be required before glazing structures or skylights are added to a new extension.
You should check with the current building regulations and your local authority before purchasing roof lanterns or rooflights, as some may require additional planning permission depending on the size or height of the structures.
Energy Efficiency
Many glass products such as windows, doors or flat roof windows are a great way to add more natural light into a property. However, it’s important to assess how these installations may affect your home’s energy effiency.
Here at Lantern Superstore, we ensure all our products offer excellent energy efficiency, with features such as thermally broken aluminium profile and advanced glazing technologies. By investing in a well-manufactured product, you will not only have one that is built to last, but that will perform well too, keeping your property comfortable all year-round.
Pitched Roof Structure
If you are looking to install roof lanterns or rooflights onto your flat roof extension, you need to assess the structure of your roof. Typically, every building will require a slight pitch angle to allow for rainwater to run off, so this is important to factor into the upstand height of any glazing structures to be installed.
To ensure proper installation, check with the manufacturers guides on upstand sizes on a flat roof.
