When should a flat roof in Dungannon be replaced?
Exposure matters too. Wind lifts tired edges, and repeated wetting and drying works at old joints, so roofs in exposed spots can wear faster than the same roof somewhere sheltered. Wherever your property is in Dungannon, a survey tells you whether the roof has years left or needs replacing now.
Dungannon's flat roofs are mostly on low-rise post-war blocks of flats, with plenty on shops with flat-roofed rear stores below flats too. 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 replacement cost in Dungannon?
Guide price in Dungannon: £2,450–£4,300 for a 20 m² extension roof in EPDM with a new deck and insulation, including VAT at Northern Ireland rates. The fixed price comes after a free survey for new and replacement roofs.

Which system should I replace my flat roof with?
The right system depends on the roof's size, shape, use and number of details, so no single material suits every roof. These are the usual starting points:
- EPDM rubber suits simple, rectangular roofs, where one sheet can often cover the area with few or no joins.
- GRP fibreglass suits roofs with many corners, rooflights or edges, and gives a rigid surface for occasional maintenance traffic.
- Torch-on felt is a layered, hard-wearing system that keeps the cost down on larger or plain roofs.
- Liquid-applied systems handle awkward details and can overlay a sound existing surface.
- Single-ply and mastic asphalt are more usual on commercial roofs, blocks and terraces.
We recommend a system at survey and explain why. Our EPDM vs GRP vs felt guide sets out the trade-offs if you want to compare first.

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.

Flat roof replacement in Dungannon: questions
Do you cover Dungannon?

How much does a flat roof replacement cost in Dungannon?
£2,450–£4,300 for a 20 m² extension roof in EPDM with a new deck and insulation, at Northern Ireland guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can you replace just part of a flat roof?
Sometimes, if the rest is sound and dry. Renovating more than half of a roof over a heated room usually brings the whole roof under the insulation rules, so a full replacement can make more sense.
Do I need to be at home while the roof is replaced?
Not for most of the job, as long as the team can reach the roof and there is room for a skip. We ask you to be there at the start to agree the plan and at the end to look over the finished roof.
