Flat roofing


We have a dedicated flat roofing team at Longworth. This means that not only are we more specialised, we can also be more competitive when it comes to providing a first-rate design and construction service.

This ‘best price’ also comes with the added security that your installation will be carried out by a well-established and secure company. Work with us and you get the best of both worlds.
