Roof lanterns: transform your extension from ordinary to extraordinary

You’ve built that dream extension. New kitchen, bigger living space, the works. But something’s off. Despite the spotlights and fancy lighting, it still feels… flat. Closed in. Like you’re sitting in an expensive box rather than the bright, airy space you imagined.

Your neighbours’ extensions? They’ve got that wow factor yours lacks. That flood of natural light that makes everything feel bigger, brighter, more alive. You’re starting to wonder if you’ve wasted thousands on a space that’ll never feel quite right.

Here’s what’s missing: A roof lantern. These architectural showstoppers don’t just add light – they completely transform how a room feels. From our budget-friendly Korniche 4 Pane (from £565.11) to the premium Brett Martin 6 Pane (from £1,004.78), we’ve got the perfect solution to turn your expensive box into the stunning space you actually wanted.

No more extension regret. Just pure, natural light streaming in from above.

What are roof lanterns and how do they work?

Think of glass roof lanterns as skylights on steroids. Where traditional flat skylights sit flush with your roof, these architectural features rise above it – creating a striking pyramid or ridge structure that captures natural daylight from multiple angles.

The anatomy of contemporary roof lanterns

At their core, modern lantern roof lights combine:

  • High-performance glazing (usually 4 or 6 panes) forming the sides
  • A central ridge or apex creates that signature raised profile
  • Thermally broken aluminium frames hold everything together
  • Double glazing as standard for year-round comfort

Our Korniche roof lanterns showcase this innovative design perfectly – slim aluminium frames that maximise glass area whilst delivering peace of mind through incredible structural strength.

How they actually work

Contemporary roof lanterns don’t just let light in from above. The angled glass roof panels catch sunlight throughout the day, funnelling more natural light into dining rooms, kitchens, and living spaces from sunrise to sunset.

Morning sun hits the east-facing panes. Midday brightness floods through the top. Evening rays catch the western glazing options. You get 360-degree illumination that transforms throughout the day.

The raised design also creates what architects call the “lantern effect” – warm air rises into the peaked space, drawing cooler air from below. Natural ventilation without opening a single window (though many models include vents for summer).

Beyond basic rooflights

Unlike flush lantern rooflights on flat roofs that can look like an afterthought, the perfect roof lantern makes a statement. They add height to rooms with low ceilings, create focal points in large spaces, and turn ordinary extensions into something extraordinary.

Whether you choose our Brett Martin 4 pane for compact spaces or the impressive 6 pane option for grand designs (up to 4000mm long), you’re not just adding a window – you’re adding architecture.

Innovative roof lantern ideas

Ready to maximise daylight in ways you hadn’t imagined? Modern roof lanterns have evolved beyond basic glass boxes. Today’s smart engineering delivers solutions that would’ve seemed impossible just a few years ago.

The minimalist marvel

Our Korniche range strips frames down to near-invisibility. More glass, less aluminium – that’s the secret. These contemporary designs use reinforced corners and hidden fixings to create an almost floating glass effect. Perfect for modern extensions where stunning aesthetics matter as much as function.

Pair one with a zinc or sedum new roof for that architectural magazine look. The contrast between natural materials and crisp glazing never fails to impress.

The self-cleaning solution

Tired of staring up at bird droppings and grime? Self-cleaning glass changes everything. The coating breaks down dirt at a molecular level, then rain washes it away. Key features include:

  • UV-activated cleaning action
  • Reduced maintenance (clean once a year, not monthly)
  • Clearer views year-round
  • Works even in light drizzle

Our Brett Martin range offers self-cleaning glass options across all sizes – and at a fantastic price compared to retrofitting later.

The custom creation

Standard sizes don’t fit? No problem. We offer bespoke sizes in both kit form and fully assembled options. Whether you’re working with an awkward roof angle or need something massive for a grand design, we’ll configure the perfect solution.

Glass options include:

  • Solar control for south-facing installations
  • Triple glazing for extreme insulation
  • Privacy glass for overlooked properties
  • Tinted options for excessive sun

The smart home integration

Imagine roof lanterns that respond to weather, temperature, and time of day. Electric opening vents, rain sensors, integrated blinds – the possibilities keep expanding. Some customers even link theirs to Alexa or Google Home for voice-controlled ventilation.

Pro tip: If you’re building a new roof or extension, consider wiring for future upgrades. Even basic models can be retrofitted with smart features later.

Types of roof lanterns

The market offers more variety than ever, but choosing the right type doesn’t have to be complicated. Let’s break down what actually matters for UK homes.

Two-wall lanterns

Perfect for corner installations where your extension meets the house. These clever designs sit against existing walls, creating dramatic height without dominating the exterior. Our Korniche models feature clean lines that blend seamlessly with both traditional and modern properties. Living rooms benefit massively from this style – natural light floods in without compromising wall space for furniture.

Traditional pyramid style glass roof lanterns

The classic choice. Four glass panels meeting at a central point create timeless elegance. Available in standard sizes or custom-made to fit your exact requirements. Most popular in white, grey, or black, though RAL colour matching means you can perfectly coordinate with windows and doors.

The unique features of pyramid lanterns include:

  • Symmetrical light distribution
  • Suits square or rectangular openings
  • Works brilliantly on flat rooflight applications
  • Maximum headroom in the centre

Contemporary ridge lanterns

Long, lean, and utterly modern. These run the length of your room, perfect for kitchen islands or dining areas. The Brett Martin 6 pane stretches up to 4000mm – that’s serious coverage. In winter, the extended glazing captures every bit of low sun, reducing heating bills whilst brightening those dark months.

Cost considerations

Our range starts at £565.11 for the Korniche 4 pane – exceptional value for aluminium construction with impressive U values. The premium Brett Martin 6 pane tops out at £1,004.78, still thousands less than comparable products on the market.

What affects pricing?

  • Size: Bigger costs more, obviously
  • Glazing upgrades: Self-cleaning or solar control glass adds 15-20%
  • Colour options: Standard colours included, RAL colours extra
  • Installation complexity: Flat roofs are the simplest to install

Most customers spend between £700-£1,200 for a quality lantern that’ll last decades. Compare that to the £3,000+ some companies charge for identical performance. Request a free quote through our configurator – prices update instantly as you adjust options.

Installation costs

DIY installation? Budget £200-£300 for materials and tools. A professional install typically runs £400-£800, depending on access and complexity. Our expert team can recommend trusted installers who know our products inside out.

Benefits that actually matter

Some of the benefits include:

Year-round comfort

Forget old-school conservatories that freeze in winter and cook in summer. Modern roof lanterns maintain comfortable temperatures all year. Thermally broken frames stop heat escaping, whilst solar coatings prevent overheating. You get complete peace of mind knowing your energy bills won’t spiral.

Property value boost

Estate agents consistently report that quality roof lanterns add 5-7% to property values. Unlike conservatories that can date quickly, these architectural features age gracefully. The clean, contemporary look appeals to future buyers as much as current owners.

Planning permission? usually not

Most aluminium roof lanterns count as permitted development. You can install without planning permission if:

  • The lantern doesn’t exceed the highest part of the roof
  • It projects less than 150mm from the existing roof plane
  • Your property isn’t listed or in a conservation area

The perfect fit for modern living

Open-plan living rooms flow better with overhead lighting. Kitchen diners feel more spacious. Even small extensions transform into bright, usable spaces. The psychological benefits – reduced SAD symptoms, better mood, increased productivity – make the investment worthwhile beyond mere aesthetics.

Installation tips

Getting your roof lantern installed properly makes all the difference between years of trouble-free enjoyment and endless headaches. Here’s what you need to know.

  • Preparation is everything: Before any glass touches your roof, ensure your opening is perfectly square and level. Even a 10mm discrepancy can cause fitting nightmares later. Most installers use a laser level for accuracy – worth borrowing one if you’re going DIY. The substrate must be solid too; any flex in the roof structure will stress the frames over time.
  • Double glazing considerations: Glass roof lanterns are made with double glazing for thermal efficiency, which means they’re heavier than you’d expect. A typical 2m x 2m unit weighs around 150kg. Plan your lifting strategy carefully – you’ll need at least two people, preferably three. Consider hiring a glass lifter for larger units; at £50-£80 per day, it’s cheaper than a bad back or broken lantern.
  • Frame installation precision: Slimline roof lanterns feature ultra-slim aluminium frame construction, which looks stunning but requires precise installation. These frames have less margin for error than chunkier alternatives. Use the provided packers to ensure perfect alignment – never force frames into position. The thermal breaks in modern aluminium are engineered to tight tolerances; forcing them risks compromising the insulation properties.
  • Weatherproofing done right: Skip the silicone gun – proper installation uses the manufacturer’s flashing kit and specified sealants. Apply primer to all surfaces before the membrane, even if it seems unnecessary. The £20 you save skipping this step isn’t worth a callback for leaks. Pay special attention to the upstand height; most require 150mm minimum for warranty compliance.
  • The unexpected bonus: Here’s something installers rarely mention: roof lanterns can enhance the ambiance of a room during rain. That gentle patter on glass creates an incredibly soothing atmosphere. Position seating areas underneath to maximise this effect – many customers say it’s their favourite feature.
  • Final checks: Once installed, run water over every joint and seal. Check internal frames for any signs of moisture after 24 hours. Test any opening vents operate smoothly. Document everything with photos for warranty purposes. Most importantly, don’t rush the final silicone beading – neat lines make the difference between professional and amateur results.

FAQs

Are roof lanterns a good idea?

They flood rooms with natural light, add serious wow factor, and typically increase property values by 5-7%. Unlike conservatories, they maintain comfortable temperatures year-round thanks to modern glazing and thermal breaks. For flat-roofed extensions, especially, they’re transformative.

Usually not. Roof lanterns fall under permitted development rights in most cases. However, you’ll need permission if your property is listed, in a conservation area, or if the lantern exceeds the highest part of your existing roof. When in doubt, a quick call to your local planning office clarifies everything.

Not typically. Standard skylights and roof lanterns are generally permitted development. The key rules: they mustn’t project more than 150mm from the roof slope and can’t be higher than the existing roof. The same exceptions apply – listed buildings and conservation areas need permission.

Not when properly installed. Modern roof lanterns come with comprehensive flashing kits and weatherproof seals. Our Korniche and Brett Martin ranges include 10-year warranties against leaks. The horror stories you might’ve heard? They’re usually from cheap imports or cowboy installations. Stick with quality products and proper installation – no leaks, guaranteed.

100% yes. Beyond the obvious benefits (natural light, reduced electricity bills, aesthetic appeal), they solve real problems. Dark extensions become bright living spaces. Gloomy kitchens transform into the heart of the home. The £700-£1,200 investment pays for itself through energy savings and property value increases.
