One of the major home improvement trends of 2026 has been the increased demand for natural light in living spaces.
It’s no surprise either, with multiple recent studies confirming that increased exposure to natural light can improve the quality of your sleep, boost productivity and improve your mood in general.
So, what’s the best way to add valuable light to your home at an affordable price? Truth be told, you can’t really go wrong with either a flat roof light or a roof lantern.
A flat roof light is installed onto a flat or low pitched roof, usually in a rectangular or square configuration. It’s predominantly made using glass, and therefore it can attract light from above. Roof lanterns on the other hand look far more dramatic, acting as a mini glass structure that protrudes outwards, attracting light from all angles.
Both options have their advantages. Below, we’ll explore them in more detail, looking at their construction, benefits, and which might be best suited to your home, depending on your priorities such as budget, light, and property type.
Introducing flat roofing systems
Flat roofs are carefully engineered, slightly sloped roofing systems perfect for single storey extensions, garden rooms or garages. They’re rectangular in shape, essentially a window coming out of your roof.
At DNA Window Solutions, we use EPDM rubber or GRP fibreglass, materials that are strong, weather-resistant and long-lasting. They provide excellent insulation, keeping your home warm in winter, cool in summer and helping to reduce energy bills.
You can add flat glass rooflights to bring in natural light while keeping a clean, contemporary look.
What are the benefits of flat roofing systems?
Flat roofs are practical, versatile and durable.
Cost-effective
A budget-friendly option compared with pitched roofs or roof lanterns.
Modern, clean lines
Smooth, minimalist design that complements contemporary homes.
Versatile
Ideal for extensions, garages, or garden rooms tailored to your specific needs.

Good insulation when installed properly to reduce heat loss, keeping energy bills down.

Introducing roof lanterns
A roof lantern is a glazed, pitched structure sitting above a flat roof. Unlike flat glass rooflights, it allows sunlight from multiple angles, filling rooms with natural daylight and adding height for a spacious feel.
Our lanterns are customisable in size, colour and glazing, with thermal breaks and high-performance glass to maintain energy efficiency while protecting from heat loss and UV rays. Perfect for kitchens, open-plan living spaces or garden rooms, they act as a stylish architectural statement.

Roof lanterns combine style, light and comfort.

Elevated glazing lets sunlight flood in, brightening your home.

Available in a variety of sizes, colours and glazing types to suit your home and specific conditions.
