EPDM Rubber Flat Roofing — Wirral, Liverpool & North West
EPDM is a tough rubber membrane — like a giant seamless waterproof sheet for your roof. No joints, no weak spots. Fits garages, extensions, dormers and commercial buildings. Lasts 40–50 years.
Domestic EPDM Flat Roofing — Plain English
We stand behind every roof we fit — covering both the rubber membrane and the labour on all flat roofing projects.
EPDM replaces old roofing felt. Where felt cracks and leaks within 10–15 years, EPDM lasts 40–50+ years with almost no maintenance. One large seamless sheet — no joints, no weak points, no leaks.
Garage Roof Replacement
Single or double garage EPDM roofs — typically completed in one day. 30-year warranty included.
House Extension Flat Roof
Kitchen extensions, bifold doors, roof lanterns and dormers — detailed perfectly.
Commercial EPDM Roofing — Warehouses, Offices & Schools
EPDM flat roofs on commercial and industrial buildings across the North West and North Wales. No hot works permit, works around your business hours.
Flat Roof Leak Repairs — Fast Response
A leaking flat roof damages ceilings, walls and electrics fast. We find the exact source first and fix it properly. No call-out charge for the initial survey.
