1. Glass Roof Extensions
glass roof extension is a bold choice that turns your space into a light-filled haven. Whether it’s a full glass roof or a partially glazed ceiling, this solution creates a sense of openness and drama.
Advantages of a Glass Roof:
- Floods the space with natural light, even on overcast days.
- Perfect for connecting with nature, offering clear views of the sky and surroundings.
- Adds a luxurious, architectural element to your extension.
Considerations:
- To manage heat and privacy, consider triple-glazed units with integrated blinds or solar-control coatings.
- Glass roofs are more challenging to clean and maintain compared to opaque roofs. Choose easy clean glass, which uses UV light to help break down dirt allowing rainwater to rinse it away.
Pitched Rooflights
For extensions with a sloping or vaulted ceiling, pitched rooflights are a fantastic way to maximise natural light. Installed at the same angle as the roof, these rooflights make the most of the vertical height and allow sunlight to flood the space from above.
Why Pitched Rooflights?
- They emphasise height and volume, creating a more spacious feel.
- Positioned strategically, they can direct light deep into the room.
- Available in a variety of sizes and styles to suit modern and traditional aesthetics.
- The Roof Maker Luxlite® offers a completely frameless view from the inside as the thermally broken aluminium frame is only visible externally once the rooflight fitted. Learn more about the benefits of a framed rooflight in our blog post ‘Know the difference: Frameless Views vs Frameless Rooflights’.
Considerations:
- Some properties and projects aren’t suitable for a pitched roof, always discuss your options with an expert.
- A pitched roof is often more costly than a flat roof, it’s important to create a clear budget before you start any project.

3. Flat Rooflights
Flat rooflights are ideal for single-story or low-pitch extensions (usually between 0-15 degrees), offering a sleek and contemporary way to let in light. These are especially popular in open plan kitchen-diner extensions, where overhead lighting can transform the ambiance, but wall space may be limited for traditional windows.
Benefits of Flat Rooflights:
- Easy to integrate into flat roof designs for a clean, minimalist look. They often work beautifully over central spaces like dining areas, creating a light-filled focal point for gatherings.
- Many flat rooflights include glazing options such as solar glass to prevent heat gain and remote-controlled blinds.
- Options are varied and aside from a standard fixed flat skylight; choices include roof lanterns, opening flat rooflights, access rooflights, circular flat skylights, walk on rooflights and modular skylights which cover larger areas than traditional flat rooflights.
Considerations:
- A flat roof has a shorter lifespan compared to a pitched roof, most last between 15-30 years depending on weather conditions and maintenance.
- A flat roof extension will need regular maintenance and an inspection at least every autumn and spring to remove debris and ensure water doesn’t pool.


4. Glass Link Extensions
A glass link extension is the ultimate way to connect two parts of your property while maintaining a sleek, modern design. These fully glazed walkways or walls can transform how different parts of your home interact.
Why Choose a Glass Link Extension?
- They offer a seamless, contemporary aesthetic that bridges old and new elements.
- Creates an architectural feature while allowing light to flow between spaces.
- Can double as a unique transition area with garden views.
- Glass links are perfect for homes with outbuildings, barns, or annexes, tying them together in a visually stunning way.
Considerations:
- Heat Loss and Energy Efficiency, some people have found underfloor heating a great way to help offset any heat loss.
- Large expanses of glass require regular cleaning to maintain their sleek appearance. It is recommended to budget for professional cleaners on a regular basis.
- Some people find the openness equals a lack of privacy, most opt for blinds and clever landscaping to assist with this.
5. Bifold Doors
Bifold doors are a quintessential feature of modern extensions, blurring the line between indoor and outdoor spaces. These doors fold neatly to the side, opening up the entire wall to your garden or patio. Opt for floor-to-ceiling bifold doors with slim frames to maximise light and enhance the contemporary aesthetic.
Why Bifolds are a Must-Have:
- They provide uninterrupted views when closed and full access when open.
- Perfect for creating a seamless flow between your extension and outdoor areas.
- Available in various materials like aluminium, timber, and uPVC to suit your style.
Considerations:
- Despite advancements in glazing technology, bifold doors can still result in greater heat loss compared to solid walls or smaller windows. Choose triple glazing and thermally broken aluminium frames to help with any heat loss. Roof Maker’s Thermfold Bifold Door system offers both of these options.
- Fitting is best left to the professionals due to all the moving parts and needing perfect alignment, this can incur extra costs compared to other solutions mentioned.


The glazing options you choose for your extension can make all the difference in how the space feels and functions. From pitched and flat rooflights to bifold doors, glass roofs, and glass link extensions, each solution brings its own set of benefits and style. Whatever you choose, invest in high-quality materials and finishes to ensure your extension is as durable as it is beautiful.
