"I recently had to carry out some repairs to my roof and got in contact with FixAroof. They provided a great level of service. Chris was very professional, responding to all of my question in a timely manner. I would definitely recommend as both Chris and his team have done an excellent job."
Nikesh Depala Customer
"From start to finish, I was very impressed with Chris and his team. I was looking for a contractor to waterproof a garage roof which was no longer watertight. His quote was very competitive; his attitude was friendly and professional; he explained the whole process involved for the works; he was easy to get hold of; his workmanship was of a high quality with careful attention to detail; he is fully insured; he completed the works within the stated timeframe. I would be happy to use him again and I would highly recommend him to anyone looking for a reliable roofing contractor."

Common Questions

Everything you need to know about working with us.

Many single-storey extensions and loft conversions fall under Permitted Development rights. However, larger extensions, properties in conservation areas, or flats will require full planning permission. We assist with architectural drawings and planning applications as part of our comprehensive service.
A standard single-storey rear extension typically takes 10-14 weeks from breaking ground to final handover. Complex double-storey extensions or projects requiring significant structural steelwork may take 16-24 weeks. We provide a detailed timeline prior to contract signing.
Yes. We carry comprehensive public liability and employer's liability insurance. All structural work is guaranteed, and we work alongside independent Building Control inspectors to ensure all work meets or exceeds UK Building Regulations.
We use a transparent, staged payment structure. Payments are tied to specific, verifiable project milestones (e.g., groundworks complete, steel installed, watertight). You only pay for work that has been completed and signed off.
