What the job involves
Flat roof repair depends heavily on which system the existing covering is. EPDM rubber splits and punctures can be patched with a bonded EPDM patch and primer. GRP fibreglass hairline cracks need a local gel coat repair. Felt roofs with pooling water usually can’t be repaired in a way that lasts more than a year.
A good flat-roof repair starts with identifying the system and its age. On ageing felt, the honest answer is often “this needs replacing” rather than patching.
Belfast — local context
Traditional material: Welsh slate and Bangor-quarried blue-black slate.
Northern Irish planning law and Building Regulations differ from those applying in England and Wales; homeowners should confirm local requirements with the Department for Communities or their district council before starting work.
What changes the price
- Flat roof system — EPDM is cheapest to patch, GRP is middle, felt depends on age.
- Size of the affected area.
- Whether the deck underneath needs checking for water damage.
- Whether pooling water (standing puddles) is part of the picture — that’s a drainage issue, not a covering one.
Timeline: Usually same-day for a localised patch.

Is it worth repairing an old felt roof?
If the felt is 15+ years old and pooling water is visible, repair is a short-term patch at best. Honest roofers will quote a replacement at the same time as the repair and let you choose based on budget and timeline.
Can I repair a GRP flat roof myself?
For a small hairline crack, in theory yes — there are consumer-grade GRP repair kits. But GRP is sensitive to temperature and humidity during the cure, and a bad repair is worse than the original crack. I’d use a professional for anything bigger than a few centimetres.
