Modern Flat Roof Extension

What is a flat roof extension?

Depending on your specific improvement project, you can choose from several square or rectangular sizes to suit your individual project. Designed to deliver striking uninterrupted sightlines that bathe the space in warm natural light, our Flat Skylight is at the cutting-edge of chic architectural design. Sitting flush (flat) to the internal plasterboard, our fixed skylights unite a fantastic frameless appearance from the interior and a fashionable, streamlined look on the outside. Traditionally styled homes in Kent can benefit too, with an elegant pitched lantern roof option tailored to your needs. Offering the widest range of bespoke design options, achieve the look you’ve always dreamt of with a FineLine Windows flat roof extension.

A made to measure modern flat roof extension in Gillingham, Chatham, Ashford, and Rochester

Modern flat roof extensions are perfect for new kitchen extensions, whilst beautifully updating existing extension spaces. No matter the project, our in-depth design process will guide you through each step so you’re fully informed of the exceptional design choices that can be achieved.

Custom-made in a variety of stunning colour choices and finishes, for a really state-of-the-art look, take your new flat roof extension to the next level with an extended internal plastered soffit system*, a modern overhang on the roof to shelter the doors and level external flooring options to harmoniously unite inside and outside spaces like no other. Able to accommodate extra large rooflights up to 23m², turn those ‘Grand Design’ dreams into a reality with FineLine Windows.

*Available in small, medium, or large, a soffit is a horizontal architectural feature built lower than the area around it. Its purpose is to conceal light fittings and speakers, adding stylish character to any extension.

The most robust & thermally-sound flat roof extension around

Incredibly durable, long-lasting and energy efficient, our flat roof extensions never fail to add contemporary character. Able to notably reduce energy bills, depending on the amount of glazing used, you can look forward to exceptional U-values as low as 0.14W/m2K. Thanks to its advanced thermally broken aluminium sections, a FineLine modern flat roof extension allows you to achieve traditional orangery aesthetics that can be used all year round, regardless of the season or the weather.

Another unique feature means it can span up to 5.8m above slimline bi-fold doors or sliding doors without costly and unattractive extra support. It also has a pre-manufactured ‘fall’ system to ensure water drains away efficiently.

'Fast-fit' flat roof designs to complement any home in Kent

A popular enhancement for homeowners that need more natural light and privacy, sophisticated, made-to-measure ‘edge-to-edge' flat skylights are a must within modern buildings across Kent and the Home Counties. Or if you’re lucky enough to live in a heritage, period, or more traditionally styled property, a gorgeous pitched lantern roof extension is sure to add unmatched grandeur.

With limitless designs and finishing touches available, we can work with your personal requirements to build a captivating flat roof extension solution that exceeds all expectations.
