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.
Whatever prompted you to look into a new roof, whether wear and tear, a growing family or plans to move, we can survey your Risca home and give you a price in writing. Homes in Wales typically come in at £6,400–£14,000, VAT included, for this kind of work. We also cover Newport, Gwent, Cwmbran and Caerphilly, and the same steps apply wherever you are in Mid Glamorgan.

Building in Risca
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
Valley terraces commonly need repointing, roof repairs, rendering and window replacement, and loft conversions can add useful space. Newer estate homes often take garage conversions, porches and landscaping.
These patterns matter for a new roof: older walls, roofs and floors in Risca can need different materials or extra preparation compared with newer homes.
Planning and building rules in Risca
As Risca is in Wales, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
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.
What happens after you get in touch?
We look at the job
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Written quote
After the survey we send a quote for a new roof that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
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 Risca property.
Finish and handover
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.
What you can expect from us
Common 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 much will a new roof cost in Risca?
As a guide, expect to pay £6,400–£14,000 including VAT for a new roof in Risca. 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 do I know if I need a new roof or just repairs?
A roof needs replacing when problems are widespread, not isolated. Signs include many slipped, cracked or porous tiles, sagging between rafters, daylight or damp in the loft, perished felt that crumbles to the touch and repeated leaks in different places. A few slipped tiles or a loose ridge can usually be repaired. We inspect from outside and inside the loft and tell you honestly which is needed.
How much does a new roof cost?
Re-roofing a typical 3-bed semi costs £6,400–£14,000, including scaffolding, new membrane and battens. As a guide, allow roughly £70–£160 per square metre of roof plus fixed costs for scaffolding and waste. Concrete tiles sit at the lower end and natural slate at the top. Hips, valleys, chimneys and timber repairs add to the price. We confirm a fixed figure after inspecting the roof and loft.
