What is a roof light?
What is a roof light – and do you need one? Discover more about roof lights and the different styles available.
Roof lights are great. As well as acting as the focal point of a space, roof lights flood the room with daylight. And with designs to suit every taste and budget, it's never been easier to reap their benefits.
But we know what you're thinking – what
is
a roof light, exactly? Is it the same as a skylight? Or a loft window? Who came up with all these names?
Let's start by clearing up this common source of confusion.
Is there a difference between a roof light and a skylight?
In short, yes – but it's not that big of a fuss.
In the spirit of the "po-tay-toe, pot-ah-toe" debate, the term "skylight" is typically used for angled installations. It can also be used for flat-roof styles – though the appearance does tend to change dramatically depending on the application.
Even so, any term is OK to use. "Roof window", "roof light", "skylight" and "loft window" are equally common. Sure, there are a few subtle differences between them. But unless you're making an enquiry to a specialist, these terms are recognisable enough that you won't have to worry about which is technically correct.
Types of roof lights
Roof lights come in several styles. Beyond aesthetics, there are benefits specific to each style, as well as important considerations around installing and using their features.
Here's a quick guide to the different types of common roof lights.
Flat roof lights
As the name suggests, these units typically sit flush to a level roof space, using a kerb system to ensure water doesn't pool on the glass.
This type of roof light is available in a variety of designs to bring light and style, regardless of room or home size. It's usually sealed, making it ideal for bringing natural light to spaces where ventilation isn't a priority (think hallways, corridors and corner spaces).
It's also possible to host flat window lights on pitched roofs. These are most common in attic bedrooms.
Framed and frameless window styles
Flat roof lights often come with the option of having a visible or integrated frame. These are, respectively, known as "framed" or "frameless" designs.
Expansion of natural light is celebrated in frameless designs, where the illusion of a pure-glass ceiling offers a touch of modern elegance. By contrast, framed window lights offer striking statement lines, providing extra depth to the feature.
Both choices are ideal for large home spaces where the light is both functional and transformative. Examples include living and dining areas.
Opening roof lights
These roof lights open and close like a horizontal window. This is the style most will think of when picturing roof window lights.
These adjustable units are an excellent solution for places where air circulation is essential, such as bathrooms and kitchens. The mechanism can be manual or automatic, depending on the user's needs – and how hard it is to reach.
Walkable roof lights
Are you planning to use your roof as an outdoor space? If you're including a roof light, it's vital that the structure is sturdy enough to walk on.
This is not a design style in and of itself. However, it's hugely important to select the right materials for the purpose. That's why companies often sell pre-built options as "walk-on roof lights" or "walkable roof lights".
Pyramid or lantern ceiling lights
These types rise up from the roof space, where multiple panes taper into points.
Commonly found in museums, libraries and orangeries, this style is all about grandeur – a far cry from the modern chic offered by seamless flat styles.
The number of bars tends to impact the end result. A rule of thumb is that the panes will need at least three bars to support the angled structure. At that number, they will still maximise light – but with a design subtle enough that it won't cause distraction in a minimalist home.
What are the benefits of roof lights?
Roof lights allow a significant amount of natural light into the room, instantly creating a brighter and more inviting environment. Through careful positioning, this sleek feature can successfully elevate dark corners, invite the outside world in, and guide the eye through the space.
Beyond making an architectural statement, good-quality window installations tend to be low-maintenance and highly energy-efficient. High-quality installations carry a long lifespan, so be sure to choose reputable providers that offer generous warranties and aftercare.
With the proper installation management, roof lights can enhance the home and add long-term value to the property price. With plenty of sizes, shapes, designs and price options, it won't be difficult to find inspiration for your space.
Roof light installation considerations
When planning a roof light for your home, be sure to think about:
- Purpose and placement: what do you want to achieve with your roof light?
- Glazing options: for example, do you need thermal or UV coatings?
- Quality of materials: because here in the UK, we get every type of weather!
- Ease of installation: you want a trouble-free installation that's simple to maintain.
- Style: do you want an eye-catching statement or a subtle feature?
Are roof lights a security risk?
As with any window in the home, roof and skylights do provide another entry point for sneaky intruders. It's not a cause for concern, though – most good ceiling windows will come with secure locking mechanisms.
At Calder Windows, we believe the security of our clients isn't just a nice-to-have – it's vital. We never cut corners and only ever work with trusted, high-quality suppliers for our lockable components.
Do I need planning permission for a roof light?
Permission is not generally required for roof lights or lanterns – provided they don't exceed rules on projection, height and glazing.
Homeowners should check with their local council, seek technical guidance on the
government planning portal and engage the expertise of a professional installer.
Some roof lights can be bought as DIY packs. But with a qualified installer, you'll make sure your dazzling new feature lasts as long as possible.
