About our Lantern Roofs

Let the natural light come pouring into your home with an Atlas lantern roof – our lantern roofs can be installed on virtually any flat roof and can turn even the darkest room into a light and bright space that would be perfect for relaxing or entertaining.

Conservatories and orangeries have long been the preferred option for adding natural light to your home, but now lantern roofs will give you a whole new range of possibilities when it comes to transforming your home. High-grade aluminum is combined with PVC and precision engineering to create a wonderful product that can transform your existing flat roof.

Contemporary living all year round

Our beautiful range of Atlas lantern roofs will mean your existing room can boast more light and a feeling of space. Precise advance engineering means no clunky bars or unsightly ridges, we can create an elegant and stylish roof that will look simply stunning. Strong and light 40mm rafters are all that you will see when you look up at your beautiful new roof.

We offer a range of colours, finishes and designs so you can pick a look that suits your style and is in keeping with your home. Whether you want something clean and modern such as white, grey or black, a more traditional wood effect – including Irish oak, golden oak, rosewood or mahogany or some quaint English style with chartwell or cream, we have something to suit your style and taste.

Secure and Energy Efficient

We understand that as well as being an addition to your home that looks great, you also want to know that your new lantern roof is secure and energy efficient.

Our lantern roof is the UK’s most thermally efficient lantern roof system so you simply couldn’t get better. We use advanced double glazing technology to ensure that you don’t lose heat through your new roof in the winter months and can keep your energy bills low. A high acoustic performance also ensures that unwanted outside noise is reduced.

We also realise that security is important which is why our lantern roofs are the UK’s strongest, ensuring your home is safe and secure.

We recently decided to replace our front door, and could not be happier with the result! Thanks so much to Kate, for her time and understanding. Cannot say enough good things about the installation, and Cameron was tidy and efficient. It's been a pleasure to work with Three Counties recently, doors and windows. Many thanks!

Excellent service!! We had 21 windows and 3 doors installed and very happy with it all. The process from start to finish was stress free and Ron and Lee who installed the windows and doors were great. Would definitely recommend!

Just had my tatty old windows replaced by Three Counties, and it’s been a highly professional job from start to finish. Communication from the administration team was prompt and courteous at all times, and installation ended up being much quicker than advertised projections. Installation was without issue and the lads who did the work were amenable to my requirements and did an excellent job. Very happy with the entire process. Three Counties were recommended to me by friends and I can certainly now recommend them to others.

Bought two new windows and a new front door from Three Counties, was very impressed with the attitude of all staff, who were friendly and informative. Price was good, and installation completed without a hitch - very happy with the final product, and would definitely use again.

We have just had all our windows (18) replaced, french doors (20 and side panels (2) by Three Counties. We could not be more pleased with their workmanship and the finished product. They left the property incredibly clean after each day, and this despite the messy nature of ripping out old windows and frames. We were kept informed at each stage and a minor snagging issue was resolved promptly and efficiently after installation. A first class service. We would not hesitate to recommend Three Counties.

Three Counties have now installed several windows and doors on our house and they're always my go-to company. I used another before I discovered them and they let me down, but I absolutely cannot fault Three Counties. From the moment you contact them they're courteous and professional, and they keep in touch with timescales and installation times. Friendly installers too, who go above and beyond. You'd think all this great service would cost more but they beat other companies on price. Highly recommended and trusted, I'd never go anywhere else now.
