At Roofing Ninjas Ltd, we are experienced GRP flat roofing installers, working across Liverpool and surrounding areas including Kirkby, Maghull, Aintree, Fazakerley, West Derby, Walton, Orrell Park, Bootle, Huyton, and Childwall.
Fibreglass (GRP) is a tough, seamless, and modern flat roofing solution, ideal for dormers, extensions, bay windows, garages, and more. We use high-quality resins, matting, and edge trims to deliver a clean, watertight finish with no joins, no leaks, and a 20–30 year life expectancy when installed correctly.
✅ Full GRP flat roof installations
✅ Garage, dormer & extension roofing
✅ Correct edge trims, expansion joints & detail work
✅ OSB reboarding & furring installation
✅ Proper substrate prep & moisture control
✅ Colour-matched topcoats available
✅ 20-year workmanship guarantee available
Many roofers offer fibreglass without proper training — we don’t cut corners. Our GRP roofs are fully built to specification, with the correct laminates, fall angles, trims, and topcoats to withstand the UK climate for decades.
Check out our gallery to see examples of our GRP work across Liverpool — clean, detailed, and built to last.

Joanne - Image 1 "Roofing Ninjas were great - very professional and hardworking guys - they did an excellent job replacing my entire roof including a large flat roof extension- they worked through the very hot weather we have experienced lately- they went above and beyond repairing additional problems like broken flags caused by the skip supplier- I would recommend them completely."

"Phil and his team of Ninja roofers recently completed extensive renovations to my rooves. One a flat lean-to workshop, a porch garage , a bay and the main roof. Each came with a detailed understanding of what work needed to be done, a drone view of the roof and a timescale that fitted well, a date was agreed and work began. I have seldom seen a team work so well and efficiently, the scaffolding, skip and supplies all arrived before the work was to start. An early rise in the morning and the team sprung in to action. Each activity taking place as planned, completed and confirmed with me. The quality of work was excellent but one item was not right to Phil. He spoke to me and said it would be better this way. He redid the porch roof ridge tiles and he was right, it looked much better. Now our house has the best roof on the estate and I was approached for details just as Phil left. I have no concerns with recommending The Roofing Ninjas. Thanks Phil and team for a job well done."

"Phil gave us a really fair quote for a new roof. Roof looks brilliant and Phil has been really good at keeping us updated with progress and has suggested some other fixes. He’s going to be doing some further work for me given how pleased we are with the initial job. Highly recommend."

"An excellent company would strongly recommend them, competitive pricing, I always say people buy from people, I felt I received an honest review of the problem (one company said I had to replace it all!!) They turned up on time and I am very pleased with the job, they even went the extra mile and fixed a few slates whilst doing the guttering at no extra cost."
