Sedgefield Premium Flat Roofing Solutions: Roof Assured Sika Sarnafil

We provide solutions for all of your flat roofing needs, whether it's a leaking roof, home improvement or a simple need for some professional advice. Our products are suitable for new build, refurbishments, and contemporary or heritage properties.

Installations include garages porches and bay windows, balconies and roof terraces, conservatories and orangeries, home extensions and home office buildings. Sarnafil single ply flat roof applications offer additional benefits when compared to other flat roofing systems. This is because your roof becomes virtually maintenance free in the same way that other PVC extension features do, such as windows, conservatories and rooflines.

Sarnafil single ply roofs have a longer life span, over 50 years and counting and are more aesthetically pleasing than other flat roofing products. Sarnafil can also be integrated with improved thermal insulation. This upgraded system ensures that porches and dormers will reduce the loss of valuable heat through traditional non-insulated roofs, saving money and reducing carbon emissions.

In addition, Sarnafil can be applied in almost any temperature and weather conditions and is an incredibly robust system that is designed to absorb the ever changing UK temperatures.

Add these benefits to a 15 year comprehensive insurance-backed guarantee, and the peace of mind that our Quality Assured Registered Installers will prepare and fit your new roofing system and you can rest assured that you, along with thousands of others, who have chosen Roof Assured, you will be a happy customer.

Home Extensions and Orangeries in Sedgefield

Sarnafil single ply flat roofs are becoming more and more popular amongst home owners across the country, especially with new home glazed extensions. Many home owners with existing extensions have also chosen to invest in the same long-term flat roof solution, eliminating the need for periodic maintenance.

Glazed extensions and the orangery style conservatory are now becoming a popular alternative to traditional extensions or conservatories. These styles can add a contemporary edge to your property, inviting more natural light, whilst also giving extending views across the garden.

Dormers, Porches and Bay Windows

Dormers and porches are an impressive feature on any home, and give real aesthetical appeal to the outside of your home.

Roof Assured by Sarnafil offer a contemporary solution for your dormers, porches and bay windows. For home owners, especially those that possess Victorian and Edwardian houses, we understand the importance of maintaining the traditional look of your roof so it complements the rest of the building. Sarnafil single ply system does just that, creating a genuine lead simulation with intricate detailing.

Garages, Balconies and Roof Terraces

Garages have become an essential part of our home, acting as a storage unit that houses everything from our vehicles, to our treasured golf clubs and garden equipment. Yet so often, garage roofs are left with inadequate roofing materials, poor drainage and are often neglected. This can lead to leaks in the roof, which in turn, can damage those all-important possessions.

Sarnafil single ply applications can transform failing roofs, into high performing systems, that offer you the customer, a guaranteed peace of mind. Your roof will look more aesthetically pleasing than traditional roofing materials such as felt based roofs that support moss and bacterial growth. Every roof can be seen as a 'life time investment' which offers real 'value for money'.

Roof terraces and balconies are the perfect solution for utilising redundant roof space, and turning this into a usable addition to your home. Transforming unused flat roofing space, into an impressive terraces or roof top garden can really increase its value and appeal.

"We approached Conservatory and Window World and from the outset felt completely comfortable with the way in which they conducted their business, there was no sales pressure and it was obvious they wanted to ensure we were going to get exactly what we wanted which was so refreshing after our previous disaster.
Not only did we go with the extension but we also had the garage roof insulated and recovered in Sarnafil and all of the roofline done in UPVC.
During the construction we had very few issues and ones we did were done in order to give us what we wanted (how many builders would be so accommodating).
We cannot praise to highly the way CWW conducted themselves during the whole process and would have no hesitation in recommending them to anyone who may be considering a similar project."
