In the UK home improvement market, the terms rooflights and skylights are often used interchangeably. Homeowners, builders, and even some designers commonly mix them up because both serve a similar purpose — bringing natural light into a room from above. However, there are important differences in design, structure, installation, and typical use cases.
At Rooflights and Skylights UK, we specialize in premium-grade glazing options for roofs, and we know how confusing these terms can be. This guide breaks down the distinctions clearly so you can choose the right option for your home, extension, loft conversion, or renovation project.
We’ll also explore where Roof Lanterns and Framed Skylights fit into the picture, and how each type enhances natural lighting, ventilation, and the overall look of UK homes.
What Are Rooflights?
Rooflights are flat or slightly pitched glazed panels installed on flat roofs or low-pitch roofs. They sit flush against the roof surface and are designed to maximize natural light without interrupting the roofline.
Key Features of Rooflights
- Typically frameless or minimal-framed
- Sleek, modern, low-profile appearance
- Ideal for contemporary extensions
- Excellent for flat roofs (common in UK rear extensions)
- High thermal efficiency and weather resistance
- Often installed in single-storey kitchen-diner extensions
- Available as fixed or opening models
Rooflights are extremely popular in the UK because they offer a clean architectural look that fits modern home designs. When homeowners want a “glass roof look” or a flat, uninterrupted glazing panel, rooflights are usually the first choice.
What Are Skylights?
Skylights are roof windows designed primarily for pitched roofs. Unlike rooflights, which sit flush with the roof, skylights are built into the roof structure and include visible frames — this is where Framed Skylights come in.
Key Features of Skylights
- Designed for pitched roofs
- Include a visible frame
- Can open manually or electrically
- Ventilation-friendly
- Suit lofts, attics, and upper-storey rooms
- Typically smaller than flat rooflights
- Great for homes with sloped roofing
Skylights bring daylight, airflow, and sky views into sloped-roof areas where traditional windows aren’t effective.
Rooflights vs Skylights: What’s the Real Difference?
While both provide natural light from above, there are clear distinctions that determine which one is more suitable for your home.
Below is the most straightforward comparison:
| Feature | Rooflights | Skylights |
|---|---|---|
| Best Roof Type | Flat or low-pitch roofs | Pitched roofs |
| Appearance | Sleek, minimal, flush | Framed, traditional roof window |
| Ventilation | Available but less common | Common and widely used |
| Frame Visibility | Often hidden | Fully visible (Framed Skylights) |
| Use Case | Extensions, kitchens, flat roofs | Lofts, upper floors, attics |
| Aesthetic | Modern, clean | Classic roof window look |
Both options serve the same purpose — more daylight — but their design differences impact how they integrate into a property.
So Which One Should UK Homeowners Choose?
The choice depends completely on your roof type and the overall aesthetic you want to achieve.
Choose Rooflights If:
- Your home has a flat roof
- You’re building a side or rear extension
- You want a modern, seamless appearance
- You prefer larger glazing areas
- You want to highlight open-plan spaces
This is why rooflights are popular for kitchen-diner extensions across the UK. They create a bright, open, luxurious feel and allow sunlight to reach deeper into the room.
At Rooflights and Skylights, our flat rooflight designs are crafted for maximum clarity, durability, and insulation — perfect for homeowners who want performance and style.
Choose Skylights If:
- You have a pitched or sloped roof
- You’re converting a loft or attic
- You want better ventilation
- You like the traditional framed look
- You need a compact daylight solution
Skylights — especially Framed Skylights — are excellent for sloped roofing setups found in semi-detached homes, terraced houses, and older builds.
Where Roof Lanterns Fit Into the Picture
Roof Lanterns are often considered a third option, especially for homeowners wanting a dramatic architectural feature.
Roof Lanterns are raised, multi-panelled glass structures that sit above a flat roof. They are more three-dimensional than rooflights and add height, depth, and visual character to a room.
Benefits of Roof Lanterns
- Bring in the most amount of natural light
- Create a luxurious, high-end look
- Add vertical height to the ceiling
- Perfect for large open-plan extensions
- Ideal for kitchen-diners and living spaces
Roof Lanterns act like a centrepiece, transforming the room and making it feel brighter and more spacious. At Rooflights and Skylights, we offer high-quality Roof Lanterns designed with toughened glass and insulated frames for year-round comfort.
