Are Roof Lanterns Expensive Compared to Skylights?
If you’re looking to bring more natural light into your home, you’ve probably come across two popular options: roof lanterns and skylights. Both are designed to brighten your space from above, but one of the biggest deciding factors for homeowners is cost.
So, are roof lanterns expensive compared to skylights? In most cases, yes – roof lanterns are typically more expensive. But the reasons why (and whether they’re worth it) are just as important as the price itself.
In this guide, we’ll break down the cost differences, what affects pricing, and how to decide which option is right for your home.
The Key Difference in Cost
At a basic level, skylights are generally the more budget-friendly option.
- Basic skylights can start from as little as £250–£500 for simple units
- Roof lanterns typically start from around £600–£1,100+ (supply only)
- Full installed roof lantern costs average around £2,250, with some projects reaching £5,000+ depending on size and materials
That’s a noticeable difference, but it’s not just about price. It’s about what you’re actually getting.
Why Are Roof Lanterns More Expensive?
The higher cost of roof lanterns comes down to their design, structure, and overall impact.
1. More Complex Design
A skylight is typically a flat window that sits flush within the roof. It’s simple, compact, and relatively easy to install.
A roof lantern, on the other hand, is a three-dimensional structure that sits above the roofline. It often includes:
- Multiple glass panels
- A full frame system
- Ridge bars and glazing bars
- A pitched design
This added complexity naturally increases manufacturing and installation costs.
2. Larger Size and Coverage
Roof lanterns are usually much larger than standard skylights. They’re designed to act as a central feature, often placed over:
- Kitchen islands
- Dining areas
- Open-plan extensions
Because they cover more surface area and use more materials, the price increases accordingly.
3. More Structural Work
Installing a skylight is often a relatively straightforward process, especially if it fits between existing roof joists.
Roof lanterns usually require:
- Structural alterations
- A built-up kerb or upstand
- Additional support
This adds to both labour time and overall installation cost.
4. Premium Materials and Finishes
Roof lanterns are often seen as a feature product, so they’re typically made with higher-end materials such as aluminium or timber.
They also tend to include:
- Advanced glazing
- Slim sightlines
- Design-led finishes
All of which contribute to a higher price point.
Are Skylights Always Cheaper?
In most cases, yes – but there are exceptions.
While basic skylights are very affordable, costs can rise depending on specification:
- Electric opening skylights
- Integrated blinds
- Rain sensors or smart features
- Bespoke sizing
Higher-end skylights can run into the thousands, narrowing the price gap between the two options.
So while skylights are generally cheaper, premium versions can approach roof lantern pricing.
What You Get for the Extra Cost
The real question isn’t just “which is cheaper?” – it’s “what do you get for your money?”
Roof Lanterns:
- Create a strong architectural feature
- Add height and visual impact
- Flood larger spaces with light
- Enhance the overall design of a room
They’re often used to make a statement and elevate the feel of a space.
Skylights:
- Provide a clean, minimal look
- Sit flush with the roofline
- Deliver practical, targeted light
- Work well in smaller or modern spaces
They’re more subtle and functional rather than design-led.
Cost vs Value: Which Is Better?
While roof lanterns are more expensive upfront, they can offer greater value in certain situations.
When a Skylight Is Better Value:
- You’re working with a tighter budget
- You want a simple, minimal finish
- The space is smaller or doesn’t need a feature
- You just need additional daylight
When a Roof Lantern Is Worth the Cost:
- You want to create a focal point
- You’re designing a large extension
- You want to enhance property appeal
- You’re aiming for a premium finish
In these cases, the extra cost often translates into a more noticeable transformation.
Do Roof Lanterns Add More Value to a Home?
This is where roof lanterns can justify their price. Because they’re a design feature as well as a functional one, they can:
- Make spaces feel larger and brighter
- Improve the overall look of an extension
- Increase buyer appeal
While skylights improve light levels, roof lanterns tend to have a bigger visual impact – which can influence perceived value.
Running Costs and Efficiency
Another factor to consider is long-term performance. Both skylights and roof lanterns are available with high-performance glazing, but:
- Larger roof lanterns may allow more heat loss if poorly specified
- High-quality units can be very energy efficient
- Proper installation is key for both
The cost difference here comes down to specification rather than product type.
The Bottom Line
So, are roof lanterns expensive compared to skylights? Yes – in most cases, roof lanterns cost more. But that higher price reflects:
- A larger, more complex structure
- Greater design impact
- Increased material and installation requirements
Choosing between a roof lantern and a skylight isn’t just about budget, it’s about what you want your space to feel like. Skylights are the more affordable, practical option, while roof lanterns sit at the premium end of the market but offer better aesthetics and design impact.
Ultimately, both options have their place – and the right choice comes down to your priorities, your space, and how you want your home to look and feel.
