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.
Planning a new roof for a home in Caerphilly means making a handful of decisions about materials, layout, finish and timing. We help you work through them at a free survey, then confirm in writing what it will cost for the options you pick. Most projects of this type need 1–2 weeks on site, plus scaffolding time, and we cover every CF83 address as well as the rest of Mid Glamorgan.

What should you budget for a new roof in Caerphilly?
What should you budget for a new roof in Caerphilly? Use the figures below as a starting point. Prices in Wales sit about 8% below the national guide, so the range here is £6,400–£14,000 including VAT. Your fixed price comes in writing once we've surveyed the property, at no charge.
| Type of job | What it usually involves | Guide in Caerphilly |
|---|---|---|
| Terraced house or bungalow | A smaller pitched roof re-covered in concrete or clay tiles, including scaffolding. | £4,600–£9,200 |
| Typical semi-detached | A 3-bed semi re-roofed in concrete or clay tiles with new membrane, battens and leadwork. | £6,400–£14,000 |
| Detached or natural slate | Larger or more complex roofs, or any roof finished in natural slate. | £11,000–£23,000 |
Your price depends mostly on:
- Roof area, pitch and the number of hips, valleys and dormers
- Covering material: concrete tile, clay tile or natural slate
- Chimneys, leadwork and roof windows to rework
- Scaffolding, access and the height of the house
Scope of the work
- Survey of the covering, timbers, chimneys and loft ventilation
- Scaffolding with edge protection, erected and removed
- Stripping old tiles or slates, battens and felt in stages
- Breathable membrane and new treated battens
- New tiles or slates, or sound originals refitted where suitable
- Ridges, hips and verges dry-fixed or bedded, with new leadwork
Building in Caerphilly
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.
Whatever era your Caerphilly home dates from, we plan a new roof around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Caerphilly
The notes below cover Wales, which is where Caerphilly sits. Rules change and every property is different, so we speak to the council before pricing your job.
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?
Free site survey
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 roof so the price reflects your home.
Written quote
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
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 Caerphilly property.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
What you can expect from us
Common questions
Do you cover Risca, Pontypridd and Gelligaer?
Yes. As well as Caerphilly, we cover Risca, Pontypridd and Gelligaer and the rest of Mid 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.
Do I need planning permission to replace my roof?
Planning permission is not usually needed to re-roof in similar materials, but it depends on the change, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. Changing the roof shape, height or covering material can need permission. Listed buildings need consent for re-roofing. We check the position for your home before quoting.
Which postcodes in Caerphilly do you cover?
We cover CF83, along with the rest of Mid Glamorgan. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
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.
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.
