Common Signs
- Standing water (ponding) that doesn't drain away after rain
- Visible cracks, blisters or splits in the roof covering
- Bubbling or lifting at the edges or seams
- Damp patches on ceilings directly below the flat roof
- Vegetation or moss growth on the roof surface
What May Cause This
- Inadequate falls (slope) causing water to pool instead of draining
- UV and weather degradation of the roof membrane over time
- Poor original installation or ageing materials (felt, GRP, EPDM)
- Blocked outlets or gutters preventing proper drainage
- Foot traffic or debris damaging the surface

Frequently Asked Questions
How long do flat roofs typically last?
This depends heavily on the material used and quality of installation — some modern flat roof systems are designed to last significantly longer than traditional felt. A roofing professional can advise based on your specific roof.
Is ponding water always a problem?
A small amount of temporary ponding after heavy rain isn't unusual, but water that sits for more than 48 hours can indicate a drainage or falls issue worth having checked.
Can a flat roof be repaired, or does it need full replacement?
That depends on the extent and cause of the damage. Some issues can be repaired locally, while more extensive or repeated problems may point towards a fuller replacement — a roofing professional would need to assess this in person.
