What is a Flat Roof Extension?

Many homes and commercial properties have flat roof extensions. Flat roof extensions are a durable option and are an efficient way to increase space in your home at a lower cost. Extensions, in general, are a great way to add property value and are one of the best ways to improve living space without having to move homes.

A symbol in big cities such as New York, flat roofs rose to popularity. Providing additional space to hang out laundry and socialise with friends. By the 1920s, flat roofs became well-established in the world of architecture.

Flat roof extensions don’t have to be designed on a large scale – you can design your extension to suit your needs and requirements. Maybe you want to extend your kitchen area or create another room to be able to socialise in. The flat roof extension cost varies depending on the size of your project and the materials used.

Flat roof extensions allow faster installation and easy maintenance. You can create a modern and stylish appearance to your extension by adding a roof light, which you can also find on pitched roof extensions too.

Flat roof lights open up your space and allow light to flood into your room, which is ideal if you want exposure to natural light. Restec liquid waterproofing systems provide peace of mind that your flat roof extension will remain completely waterproof.
