Why Choose Fibreglass Flat Roofing?

The EVOSEAL Superdeck600 Fibreglass Flat Roofing System has been designed with durability & longevity in mind. With its 100% seamless, leak proof surface our Flat Roofing System will withstand all British weathers, keeping your property protected from the elements 24 hours a day, 365 days a year.


Our GRP (Glass-fibre Reinforced Polyester) Flat Roofs are suitable for all residential, commercial and new build installations of any shape and size. The stylish, yet sympathetic finish blends in with all surroundings, making it an attractive addition to any style or type of property.


The extremely strong & durable surface can be walked across without fear of damaging, making it also ideal for covering balconies, terraces & high foot traffic walkways. And unlike many of its competitors our Fibreglass Flat Roofing System is blister, crack & split resistant, it is also bird peck proof, doesn’t perish and is maintenance free.

Our Flat Roof Fitters


All our Flat Roof installations are carried out by our own directly employed skilled fitters who will provide you with a polite and courteous on-site service from start to finish. Our fitters are also happy to talk you through your installation as it happens if you wish.

The EVOSEAL Guarantee


You can also take comfort in the knowledge that we only use roofing materials that have been approved by the BBA (British Board of Agreement standards). Using BBA approved materials enables us to offer our unique 'Lifetime Guarantee', so no matter how long you own the property you will always be covered. EVOSEAL guarantees are transferable should you decide to sell the property and are Insurance Backed for absolute peace of mind.

We are delighted with our new garage roof. Since you installed it there has been lots of rain but the garage has been completely dry unlike before, it looks excellent too. I would recommend Evoseal for any flat roof.

Chris Holliehead
Melton Mowbray

Thank you so much Evoseal for the fantastic job you did on my mums garage in Melton Mowbray. Not only a good job but the fitters even cleaned up after themselves! 

Worth every penny... I would recommend to everyone. Thanks guys

Wayne & Anne Aspinall

Evoseal did a great job replacing our flat roof. They were reliable, hard working and tidy. Despite bad weather they got the job done and we are very pleased with the roof. We would highly recommend Evoseal.

Garry & Val Atkins

Fantastic flat roof job by Evoseal. I would happily recommend the company to others. How refreshing to have a team of two fitters who were very professional, and polite. They completed the job on time despite some inclement weather, both were so helpful and took great pride in their work. Well done Evoseal.

Mr & Mrs Blackman

The roofers were exceptionally polite and left the site clean and tidy both days. The weather was very hot but they did not complain once. Our new roof looks very good and has been commented on by our neighbours and visitors. Thank you Evoseal.

Brian Highe

Thank you to you and your team for a first class job on our dormer roof. I would recommend you to all new customers. Thank you once again for a great job.
