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.
For a homeowner in Tonbridge, planning a new roof tends to begin with two questions: what will it cost, and how disruptive will it be? Our guide range is £7,800–£17,000 including VAT, and a typical job runs to 1–2 weeks on site, plus scaffolding time. Both numbers firm up once we have seen the property, measured up and agreed exactly what is included.

How much does a new roof cost in Tonbridge?
No two jobs cost exactly the same, but the ranges below give a fair picture of a new roof in Tonbridge. Pricing for the South East runs about 12% above the national guide, and the overall guide is £7,800–£17,000 with VAT included. We'll confirm your figure after surveying the property for free.
| Type of job | What it usually involves | Guide in Tonbridge |
|---|---|---|
| Terraced house or bungalow | A smaller pitched roof re-covered in concrete or clay tiles, including scaffolding. | £5,600–£11,000 |
| Typical semi-detached | A 3-bed semi re-roofed in concrete or clay tiles with new membrane, battens and leadwork. | £7,800–£17,000 |
| Detached or natural slate | Larger or more complex roofs, or any roof finished in natural slate. | £13,500–£28,000 |
The main things that change the figure:
- 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
What’s included?
- 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
- New tiles or slates, or sound originals refitted where suitable
- Ridges, hips and verges dry-fixed or bedded, with new leadwork
- Waste removal by skip and a clean site on completion
Building in Tonbridge
Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.
Victorian terraces suit loft rooms and rear extensions; weatherboarded and timber-framed buildings may need cladding repairs and lime work. Newer estate homes often take garage conversions, porches and landscaping.
That variety is why a guide price for a new roof in Tonbridge is only a starting point; the survey shows what your particular property needs.
Planning and building rules in Tonbridge
Tonbridge is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
Re-roofing a house with similar materials does not usually need planning permission in England. Listed buildings and conservation areas may need consent if the covering changes.
Replacing more than a quarter of a roof’s covering counts as renovation under Building Regulations, so the work is notified and the roof insulation may need upgrading. 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.
The four stages
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.
Your fixed price
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.
Dates and permissions
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
The work itself
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.
How we work
Questions about a new roof in Tonbridge
Do I need planning permission in Tonbridge?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Tonbridge is in England, so England'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 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 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.
Can my old tiles or slates be reused?
Old tiles or slates can sometimes be reused if they are sound, which can help keep the look of a period house. Many older concrete tiles and some slates are porous, cracked or have failing fixing nibs, so they would not last. Reclaimed slates or tiles can make up shortfalls. We check a sample during the survey and explain the cost difference.
Can you combine a new roof with other work?
Yes. Because we manage several trades under one contract, we can plan a new roof alongside other work on your Tonbridge home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
