Louise24 October 2025When we first started our building work, I was terrified. It’s such a huge investment, and there’s so much that can go wrong. We met with eight different suppliers, and when we came across Warm Roof, I immediately liked them. I hesitated because they were a smaller company so decided to go with Anglian Home instead. Even though I’d read plenty of negative reviews, I assumed a big company would be the safer choice. The sales rep was great on his house visit - but after that, comms went downhill fast. I decided to trust my gut and go with Warm Roof. Shaun was patient and responsive, answering all my (many!) questions. The installation team was fantastic, even making a last-minute change when I changed my mind, something they had every right to refuse. But Shaun went above and beyond to make sure I was completely happy. And I am! The finished result is absolutely perfect. The difference in the warmth of our house is incredible, far beyond what we expected.Posted on Trustatrader
Anna1 October 2025Warm Roof Division have just finished replacing our glass roof to a solid Leka system. Could not be happier with the result. Every single member of the team is professional, thorough, friendly and just lovely to have on site throughout the project. Thanks Shaun, Dan, Dave and the whole team - the work has entirely changed how we'll use that part of the house and we're delighted.Posted on Trustatrader

Jennifer10 March 2025This company provides an excellent product. They are excellent communicators. Each of trades needed to install the roof arrived promptly each day and worked hard to complete the work. It was excellently project managed to bring in each trade at the appropriate time and they all kept the area very tidy. Even the man clearing the rubbish at the end was methodical. I have no hesitation in recommending this company and the service they provide. A really good team and nice people.Posted on Trustatrader

Jim9 August 2024From the initial consultation visit to clearance of site, this project was exemplary. The whole team were friendly, courteous and considerate. Little touches like an on-site Portaloo were very much appreciated. The work undertaken was very high quality and we have been left with an excellent conservatory replacement with a solid roof. We were amazed at what they achieved in a short period of time. I would highly recommend them - one of the best experiences we've when renovating our house.VerifiedPosted on Whichtrustedtraders12 June 2024Endorsement Reference A glass conservatory roof replaced by a fully insulated tile effect roof. The experience was excellent from start to finish. It was well coordinated, communication was excellent. All members of the team were polite, friendly and professional.VerifiedPosted on Whichtrustedtraders12 June 2024Endorsement Reference Warm roof division replaced the glass roof of our conservatory with a tiled one with insulated ceiling. plastering and lighting. Through every step they were excellent - the initial consultation/quote was clear and thorough, with no hard sales technique or pressure. We were kept updated throughout the process which was subject to late changes due to weather. The previous roof leaked and we were worried this might continue. Initially it did, but Shaun and his team were very thorough in finding the cause and reassured us they wouldn't rest until it did. They thoroughly checked and replaced some work, but eventually discovered it was down to very porous house bricks. They then covered the rear of the house with sealant which seems to have solved the problem (it has remained dry through several very heavy downpours that would previously have caused a leak). I cannot recommend them enough.VerifiedPosted on Whichtrustedtraders

Martin Wright31 January 2024Having our conservatory roof replaced was the best money spent , its now a room of our house and it really works ! the room is now warm and usable in the winter , we rarely have the heating on now , Shaun and all the guys who worked on our roof were spot on and would totally recommend using Warm Roof , Martin WrightPosted on YellMohammedP-3817 June 2022Absolute Gem of a CompanyI've Got nothing but absolute total respect for Sean, Emma and their family run company. Right from the start when Sean came from warm roof division to give a quote there was no pushy sales tactics. He explained everything professionaly and was very respectful of my time and left me to have a good think about it. The quote was halfway between local builders and the very top companies for Supalite conservatory roof tiles installation. After the job was completed I'm now soo happy I've got a conservatory roof that not only looks fantastic, but will last a long time. It's also cool in the melting summer we're having and most probably will keep the warmth in the winter. I thoroughly recommend Warm Roof Division, you won't be disappointed if you choose them for your conservatory roof tiling.Posted on YellMariaT-18111 September 2021Very very pleased with end result.Shaun, Adam and the team delivered an excellent service and were very good at keeping me updated with the progress.A very big Thank YouPosted on Yell
