Value for money: 11/10
Professionalism: 10/10

William and his team are now our first call for any roofing and guttering work. Star find!
William replaced the fascias, soffits and guttering at the front of my property and did a great job.

He was professional, reliable and knowledgeable and kept us up-to-date throughout the job. I will definitely use him again and would recommend him to anyone looking for an excellent roofer.
William came and gave us a very thorough quotation, viewing the roof from the ground, inside the attic and looking at areas of the house where we’d had a leak.

We discussed options and his advice was very practical and honest. He was prompt in replying to messages and on time for the job. He provided updates as the job progressed, including photos.

I appreciated how he explained problems and what he was doing very clearly.
Superb job from start to finish.

After accepting the quote, the works were completed within a couple of days. Everywhere was left clean and tidy with all old materials taken away. Extremely happy with the end result and the price. I wouldn't hesitate to recommend the team to friends and family. Thank you!
William and his team did a fab job when my roof needed repairing. For me, the best part was that he kept me informed all the way through the job (took approximately half a day), and that always gave me comfort that everything was being done to a high standard.

Finally, all of Williams's work come with a 10 year guarantee :) - I would hire William again and surely recommend him to friends and family.
William was friendly and professional, responded quickly and spotted that there was a further problem with the roof and recommended a solution.

He kept me well informed and took photos to help explain what needed to be done. He was able to schedule the work the following week and arranged extra help to complete it earlier than expected and before the weather turned bad. All work was completed to my satisfaction and everything was left tidy. Great job, I would use again.
William went over and beyond to make sure that my elderly grandparents were taken care of, and his transparency is legendary.

He called us at least once a week to make sure we were okay during the lockdown, asking whether the leak was causing any further issues, and volunteering to come over to put in intermediary measures if required.
William provided an honest and reliable quote for our gutter replacement.
He provided suggestions to improve the flow of rainwater by adding an additional downpipe. He attended the property on time and completed the job in a timely manner. To date, following the rain, the guttering is performing to a high standard with no leaks.
From the quote to the completion of the roof, A** service and communication.
Friendly, professional and prompt.

William communicated well and explained about work and cost. Job was done within a very reasonable time frame of assessment to completion. I was safe in the knowledge there was a ten year guarantee for the work completed done and I'm confident that William and his team did a fantastic job. Would recommend to others.

High performance felt flat roofing: The benefits

High performance felt roofing is one of the most popular flat roofing materials and it has been used for over 50 years in the roofing industry. It is commonly used on garage roofs and is the top choice for people who are looking for inexpensive and lightweight roofing.

Cost-effective: Felt roofing is more affordable to install and cheaper to maintain than other flat roofing materials such as EPDM rubber and GRP fibreglass roofing.
Lightweight & flexible: Felt is very lightweight, so it is ideal for smaller structures as well as larger ones. It can be used on roofs of any shape or size.
Easily repairable: If your felt roofing becomes worn or damaged, it is really quick and easy to repair.
Great performance: Felt roofing can provide weathertight and durable roofing systems when installed correctly. We used the best tried and tested products.
Quick installation: The latest three-layer felt roofing is quick and efficient to install with a torch-on system.
