A flat roof replacement strips the old covering from a low-pitched roof and lays a new waterproof system, usually EPDM rubber, GRP fibreglass or torch-on felt, over a sound deck with correct falls, upstands, trims and outlets so rainwater drains away.
If you live in Strabane and are weighing up a new flat roof, the starting point is a visit to measure up and talk through what you want, which costs nothing. We cover homes across BT82, and a typical project of this kind in Northern Ireland lands somewhere in the £1,700–£3,900 bracket, including VAT. The exact figure depends on size, access and the finish you choose.

What are homes like around Strabane?
Tyrone is largely rural, with detached houses and bungalows on individual plots across the countryside, many finished in render or roughcast. Omagh, Dungannon, Cookstown and Strabane have Victorian terraced streets, post-war estates and newer developments, and stone farmhouses survive in older rural areas.
Wet and fairly cool, with upland exposure in the Sperrins and frost common through the winter months.
Knowing the typical building types in County Tyrone helps, but a survey of your own home in Strabane is what decides the right approach to a new flat roof.
Do you need permission in Strabane?
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Strabane comes under Northern Ireland, covered below, and we raise any questions with the council before your quote is finalised.
In Northern Ireland, re-roofing with similar materials does not usually need planning permission outside listed buildings and conservation areas.
Significant re-roofing should be checked with building control under the Building Regulations (Northern Ireland). Bats are protected across the UK; if they roost under roof tiles, soffits or fascias, work stops and a licensed ecologist advises before it restarts.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Survey and measure
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new flat roof so the price reflects your home.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Strabane property.
Build and hand over
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
Why homeowners choose us
Common questions
Do I need planning permission in Strabane?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Strabane is in Northern Ireland, so Northern Ireland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Is a flat roof suitable for a roof terrace?
A flat roof can only be used as a terrace if it is designed for it, with joists strong enough for people and furniture, a hard-wearing surface, safe edge protection and correct drainage. Using a standard extension roof as a terrace can damage it and may need planning permission and building regulations approval. We can advise on what a conversion would involve.
Can you repair my flat roof instead of replacing it?
A flat roof can often be repaired if the damage is limited to a small split, a failed joint or a loose upstand and the rest of the covering is sound. If the deck is soft, the covering is blistered or cracked across the roof, or leaks keep returning, replacement is usually better value. We assess the whole roof and give you an honest recommendation.
How long does a flat roof replacement take?
Replacing a typical extension or garage flat roof usually takes one to three days. Stripping and any deck repairs come first, then insulation where agreed, the new membrane and the trims and outlets. GRP needs dry weather and time to cure, and we plan around the forecast. Larger roofs or roofs with many rooflights take longer. We confirm timing with your quote.
How much will a new flat roof cost in Strabane?
As a guide, expect to pay £1,700–£3,900 including VAT for a new flat roof in Strabane. That range is adjusted for Northern Ireland, which runs about 14% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
