When is a repair the right answer in Bangor?
Landlords and managing agents in Bangor need a repair done properly once, rather than a quick fix that brings tenants back on the phone a month later. We trace the leak to its source and confirm the price in writing, so the repair can be approved and booked without guesswork.
Around Bangor, flat roofs are common on shops with flat-roofed rear stores below flats and on newer estates where the first extension roofs are now being replaced. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a flat roof repair cost in Bangor?
Guide price in Bangor: £130–£440 for a localised patch repair, including VAT at Northern Ireland rates. We confirm the price once we've traced the leak or seen the damage.

| Upstand or flashing repair | £220–£570 |

Why does a flat roof leak in one place but drip somewhere else?
Because water rarely comes through the ceiling directly below the hole. It gets in at one point, runs along the deck, a joist or the top of the insulation, and drips wherever it finds a low spot or a gap in the ceiling.
That is why a patch over the damp patch so often fails. Before we repair anything, we work back from the stain to the likely entry point and check the usual weak spots: upstands where the roof meets a wall, flashings and cavity trays above them, laps and seams, outlets and gutters, drip trims, rooflight kerbs, and any fixings or cables that pass through the covering. The fault is frequently at an edge or a wall rather than in the middle of the roof.
Sometimes the cause isn't the roof at all. Defective pointing, a failed cavity tray or a cracked coping above the roof can let water in behind the upstand, and condensation in a cold roof can look exactly like a leak. Our guide to flat roof leaks covers these causes. If the path can't be found by inspection, a leak tracing survey is the next step.
What's included?
- Inspection of the whole roof, not just the wet patch
- Upstands, flashings, laps and seams made good
- Fixed price confirmed in writing before work starts
- Repairs with materials compatible with your roof system
Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.
