Company Details

My 26 year old flat office roof was deteriorating badly and was beginning to leak. I had researched potential roofing companies thoroughly and decided on a Fibreglass warm roof from Diamond Flat Roofing. What a decision! The team arrived promptly on the Monday morning and worked nonstop for two and a half days. Their work was first class and the finished roof is magnificent. No more worries when it rains. I would have no hesitation whatsoever in recommending DFR Ltd to my family and friends.

What an amazing and professional roofing company. In 2021 I had a cowboy builder that destroyed my single storey extension roof which leaked continuously and unsafe. Alistair and his team were great with communication and very detailed in their work. Arriving on site for 0730 and working all day. Highly recommended

Great service good advice.

First class experience throughout. We were advised on the choice of roof and the pros and cons of cold vs warm roof. Installed as promised with beautiful parapet roof. All done promptly and as promised. Will be approaching them to quote for another job shortly 👌

We have just had our roof’s refurbished by Al and his team. The work they carried out is excellent. This was after having other , so called, professional roofers carrying out botched repairs work. Al identified the problems and gave us recommendations and we chose a Polyroof system, with an independent 20 year guarantee, which covers both labour and materials, should there be any issues in the future ( which we don’t expect because Al and his team have carried out an excellent job) We have peace of mind that our roof’s are now water tight We highly recommend Al and his team, thank you guys for a great job, which was professional from start to finish.

Diamond Fibreglass recently completed my flat fibreglass roof. Alastair and his team were very professional from start to finish, friendly, hard working with an excellent end result. I can definitely recommend Diamond Fibreglass.

The response, speed and professionalism of Diamond Fibreglass has been exceptional. A great repair to a victorian Bay window flat roof

Fabulous job done for my flat fibreglass roof, from design to finish, with high quality, expertise workmanship, efficient work process and value for money. I’m very happy to recommend Diamond Fibreglass.

Ali and team, I want to express my satisfaction with all aspects of the job. The quality of the workmanship and materials, quickness of the time frame in which you did the job, the cleanliness of the whole operation from start to finish and the friendliness and courtesy of the crew was exceptional. Thank you for a great job, would highly recommend.

100% recommend Diamond Fiberglass. Experts in their feild and instantly put your mind at rest. Excellent craftmanship and all comes with a polite smile. I wouldnt go anywhere else. Thanks Diamond fiberglass team

THEY FLOODED MY CUSTOMERS EXTENSION! Be sure to read there 200 pages of terms and conditions before committing. They took my waterproof sheets off the roof that were on for two weeks without any issues and put their covers on which had knife cuts in and NOT WATERPROOF. They state it’s customer’s responsibility to ensure it’s watertight and after THEY flooded half the house the director Alister says ‘these things happen’ and check our terms and conditions. Costing a lot of time and money to put their incompetence right. Don’t bother with this one, nothing but grief

Al and his team were brilliant. I had a new extension built only four years ago with a flat roof. The flat roof had problems from the start. Al sorted out why it was leaking, the mould problem because of the condensation and the rotting boards, They were very professional and kept me informed the whole time explaining everything as they went along which was excellent. I now have a beautiful new roof which is perfect and looks amazing. I would recommend them to anyone including family and friends.

Ali and team fixed our flat roof/ coping stones that were leaking into a bedroom. They offered a range of solutions and once we'd agreed to move forward the job was done to a great standard with no fuss or mess. We were very impressed with the team who were polite and turned up when they promised too. Roof repair looks good and has worked a treat. I would thoroughly recommend Diamond Fibreglass.

After having a bodged rubber roof done 3months ago , diamond was recommended to me to redo roof properly. , can I say they were absolutely top drawer on time , professional , courteous , knew what they were doing. , looks amazing , how different two companies can be , love it , no really love it , thanks a million

Fantastic service from start to end, the guys have done an amazing job on the roof and were extremely proffesional and thorough. Highly recommended!

Brilliant service and finished job. Very polite and carefull workmen who left the premises clean and tidy.

Alistair and his team replaced my flat roof for me over my garage, utility, porch and bay window. The job had its challenges, with part of the wooden joists being rotten. The job became longer due to the wood work needing to be replaced. This was no problem to them. They also insulated my roof in all areas apart from above the garage, where previously there hadn’t been any. Great friendly, professional team who were also very polite and courteous to my neighbours. Would highly recommend.

Just had my lounge extension roof replaced .Excellent end result from the Diamond Team. Can't fault the workmanship,visually improved and now have peace of mind for some years to come.Would definitely recommend them to others. J. v. Birmingham.

Wanted a long term fix for my leaky kitchen roof so didn't want to go down the felt road. They removed the old felt then repaired the rotten wood underneath and then applied their fibreglass roof system. Very polite and friendly. They also cleaned up before they left. Over the moon with the result and have piece of mind that its not been botched with the old roof left rotting underneath like some other companies would do!! Highly recommend.

Brilliant job from this company. Quality of work was excellent and the guys were polite, professional, clean and tidy. Managed to fit us in early which was great. Would highly recommend and can’t wait to have them back next year to do our balcony roof.
