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.
If you are planning a new roof anywhere in West Glamorgan, including Swansea, Neath, Briton Ferry and Gorseinon, we can visit, measure up and talk through the options. The planning and building regulations we work to are those for Wales, and we check them for your address before quoting. Prices remain guide figures for Wales, at £6,400–£14,000 including VAT, until the survey is done.

Housing across West Glamorgan
Swansea's Victorian terraces climb its hillsides, its centre was largely rebuilt after wartime bombing, and Neath and Port Talbot have industrial terraces and post-war estates. Gower villages have stone cottages, and Pennant sandstone is common in older walls. Newer estates have grown on the edges of the main towns.
Hillside terraces often need repointing, rendering, roof repairs and window replacement, and loft conversions can work well. Gower stone cottages call for lime-based repairs, and estate homes commonly take extensions and driveways.
Swansea Bay and Gower face wet westerly weather and salt, and steep streets can affect access and scaffolding.
Planning and building rules in West Glamorgan
Which rules apply depends on where you live. For West Glamorgan, the answer is Wales, and the points below reflect that; we verify them with the council before quoting.
Re-roofing with similar materials does not usually need planning permission in Wales, except on listed buildings or where a conservation area restricts materials.
Building Regulations in Wales apply to major re-roofing, including insulation upgrades. 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.
How does the job run?
Survey and measure
A free survey comes first. It gives us what we need to price a new roof properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new roof.
Booking the work
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 West Glamorgan property.
Build and hand over
Our trades complete a new roof while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
What you can expect from us
Frequently asked questions
How much will a new roof cost in West Glamorgan?
As a guide, expect to pay £6,400–£14,000 including VAT for a new roof in West Glamorgan. That range is adjusted for Wales, which runs about 8% 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.
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.
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.
What happens if it rains during the work?
We strip the roof in sections and only remove as much covering as we can replace or protect the same day. New breathable membrane goes on straight after stripping, which keeps most rain out, and we sheet exposed areas at the end of each day and before forecast showers. If heavy rain or high winds are forecast, we pause work. The house is never left open.
Do you cover Swansea, Neath and Briton Ferry?
Yes. As well as West Glamorgan, we cover Swansea, Neath and Briton Ferry and the rest of West Glamorgan. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
