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

Joan and Christopher Gilligan

Grantchester. Cambridgeshire

Thank you Evoseal, we are very pleased with the work carried out and your work force were, without doubt, the best workers we have ever experienced. Please pass on our thanks. My spouse was working away in his study, which is upstairs and overlooks the roof, and was able to have his usual Zoom and conference calls without being aware of the lads working away in front of him. So, thanks again to your efficient team.

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.

Pat Hawtin

Dear Darren, I am sending you this thank you for an excellent job on replacing my faulty flat roof. The work was carried out in a very professional and friendly manner, and I would have no hesitation in recommending your company 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.
