Pitched Roof Extensions
Ultraroof Extension
Using the ultimate in lightweight tiled roof solutions, an Ultraroof Extension uses brick or super insulated columns to create a stylish new space. With Ultraroof, you benefit from a vaulted plastered ceiling on the inside which adds to the dynamic feel of the new room. On the outside, it is finished with authentic and bespoke lightweight tiles which are available in three colour matches to compliment your home. You can also create a feature by inserting full length glazing panels which will flood the new room with natural light and warmth from the sun.
Livinroof Extension
If you love the idea of having bi-fold doors, the Livinroof Extension can make your dream a reality. Right now, a Livinroof Extension is the most versatile product on the market and that is because it can be constructed in almost any shape or size – so the design options are endless. With the ‘hybrid’ roof design, you can add shaped glass into the stylish grey solid roof and this is enormously beneficial if you need to add more light into the property. The Livinroof is also extremely well insulated so you can always enjoy the new room no matter what the weather is like outside.
Flat Roof Extensions
Ultrasky Flat Skylight
If you are having a flat roof extension, the Ultrasky Flat Skylight is a great option if you need to let some light in. Customers really like its distinctive frameless edge-to-edge design, and you have the option of blue glass too.
What this Ultrasky Flat Skylight does is allow a huge amount of light into the room which is a huge positive. The fully insulated frame with ‘Warm Frame’ technology and high-performance noise reducing glass means the Ultrasky Flat Skylight reduces outside noise, offers a solid thermal efficiency and is available in sizes up to 1.4m x 2m.
Ultrasky Lantern Extensions
With a flat roof extension, you can also choose to have an Ultrasky Lantern. These offer an alternative, but equally stylish option, and allows you to enjoy lots more sky. With slimline bars and fewer of them compared to other lanterns, you will be adding a light and airy solution to your home extension. Whether you are considering a small lantern roof extension or something much larger, the benefits an Ultrasky Lantern can bring to an extension, is incredible. They are a new, versatile and stunning way to improve your home and are available in sizes up to 5.8m x 4m.

Frequently Asked Questions About Extensions
Do I need planning permission for an extension?
Many home extensions fall within Permitted Development Rights and do not require planning permission. However, this depends on the size, design and location of the extension. If planning permission is required, our team can advise you on the process and help ensure your project meets all relevant regulations.
Are glass roof extensions energy efficient?
Yes. Modern glass roof extensions use high-performance glazing designed to retain heat during winter while helping to reduce solar gain in the summer. Combined with thermally efficient frames and roofing systems, they provide a comfortable living space throughout the year.
What is the difference between a glass roof extension and a solid roof extension?
Glass roof extensions maximise natural light and create a strong connection with the garden, making them ideal for bright, open-plan living spaces. Solid roof extensions offer a more traditional room-like feel with enhanced insulation and are often chosen for kitchen and family room extensions.
Can I have bi-fold or sliding doors in my extension?
Absolutely. Aluminium bi-fold doors and sliding patio doors are among the most popular choices for modern extensions. They allow large glazed openings that flood your home with natural light while creating a seamless transition between your indoor and outdoor spaces.
How long does an extension project take?
The timescale varies depending on the size and complexity of the project. Following your consultation and survey, we will provide a clear project schedule so you know exactly what to expect throughout the installation process.
Do extensions add value to a property?
A well-designed extension can significantly increase both the usable living space and the value of your home. Popular projects such as kitchen extensions, open-plan living areas and garden-facing extensions are particularly attractive to prospective buyers.
What type of extension is best for my home?
The best option depends on how you want to use the space. Glass roof extensions are ideal for maximising natural light, while solid roof extensions provide excellent thermal performance. Aluminium extensions offer a contemporary appearance with slim sightlines and large areas of glazing. Our team can help you choose the right solution for your property and lifestyle.
Can I visit a showroom before deciding?
Yes. Hadleigh Glass has showrooms across Suffolk and Essex where you can view extension styles, roofing systems, glazing options and aluminium doors in person. Visiting a showroom is a great way to explore ideas and discuss your project with our experienced team.
How much does an extension cost?
The cost of an extension depends on factors such as size, design, roofing system, glazing options and site requirements. Every project is unique, which is why we provide a tailored quotation based on your specific requirements. Contact our team to find out more.
