Commercial flat roofs cover a wide range of buildings — shopfronts, offices, warehouses and industrial units — and downtime matters as much as the finished roof. GRP fibreglass roofing is well suited to commercial buildings because it's low-maintenance once installed and can usually be laid in sections, so parts of the building can stay in use while work continues on the roof.
What's included
- Site survey and written quotation with a clear project timeline
- Work scheduled around trading hours or planned closures where needed
- Sectional deck repairs and GRP installation across large roof areas
- Upstands, rooflight kerbs and plant-room detailing
- Sign-off documentation and guarantee for insurance and lease records
Signs you might need this
- Your commercial roof is leaking or showing signs of ponding water
- You're managing a lease renewal or insurance inspection that flags roof condition
- An existing felt or asphalt roof needs replacing without shutting the building for long
- You want a lower-maintenance roof covering going forward
Working around your business
Commercial jobs are quoted with a schedule that accounts for how your building is used, including access, working hours and any areas that need to stay operational. Larger roofs are typically broken into sections so the building is never left fully exposed overnight.
