A roof replacement, or re-roof, strips the old tiles or slates, battens and felt from a pitched roof and replaces them with a new breathable membrane, battens and covering, repairing timbers and renewing ridges, valleys and flashings at the same time.
Anyone planning a new roof in Carrickfergus wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £6,000–£13,000 including VAT for Northern Ireland up front, explain that work normally takes 1–2 weeks on site, plus scaffolding time, and confirm both in writing after a free survey of your property.

Local housing and a new roof
Belfast has long rows of red-brick Victorian terraces, Edwardian villas in the north and south of the city and large post-war estates, while towns such as Ballymena, Antrim, Larne and Carrickfergus mix terraces, semis and newer developments. Dark basalt appears in older rural buildings, and pebbledash or roughcast is a very common finish.
Terraces suit loft conversions and rear extensions, and many need window and roof renewal. Pebbledashed homes commonly need re-rendering, and detached rural houses often take extensions, porches and driveways.
None of this holds for every street in Carrickfergus, which is why we look at your actual house before pricing a new roof rather than assuming from its age alone.
Do you need permission in Carrickfergus?
Which rules apply depends on where you live. For Carrickfergus, the answer is Northern Ireland, and the points below reflect that; we verify them with the council before quoting.
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.
What happens after you get in touch?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new roof, and photograph or measure anything the quote needs to reflect.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new roof are in place before the first day on site.
Finish and handover
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.

Roof replacement in Carrickfergus: questions
How long does a roof replacement take?
Re-roofing a typical semi-detached house takes around one to two weeks once scaffolding is up, depending on the roof's size, complexity and the weather. Smaller terraced roofs can take a few days. Scaffolding usually goes up a day or two before work starts and comes down once everything is inspected. We give you a programme and keep the roof weathertight overnight.
How long will a new roof last?
A well-installed roof lasts for decades. Concrete tiles typically last around 50 years or more, clay tiles longer, and natural slate can last a century with proper upkeep. Lifespan depends on the quality of materials, fixings, ventilation and leadwork, and on how exposed the roof is. Keeping gutters clear and fixing slipped tiles quickly helps it reach its full life.
Will my loft insulation and ventilation be improved?
Re-roofing is a good time to improve loft ventilation and insulation. A breathable membrane and eaves or ridge vents keep air moving and reduce condensation in the loft. Building regulations may require insulation upgrades when a large part of the roof is renewed. We check your current insulation and ventilation and include any required improvements in the quote.
Do I need planning permission in Carrickfergus?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Carrickfergus 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.
How much will a new roof cost in Carrickfergus?
As a guide, expect to pay £6,000–£13,000 including VAT for a new roof in Carrickfergus. 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.
