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.
Every house in Swanley is a little different, so we never price a new roof from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in the South East should budget £7,800–£17,000 including VAT, with work typically taking 1–2 weeks on site, plus scaffolding time.

What should you budget for a new roof in Swanley?
No two jobs cost exactly the same, but the ranges below give a fair picture of a new roof in Swanley. 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 Swanley |
|---|---|---|
| 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
- Breathable membrane and new treated battens
- New tiles or slates, or sound originals refitted where suitable
- Waste removal by skip and a clean site on completion
Local housing and a new roof
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.
With that background in mind, here is how we typically handle a new roof for homes in Swanley, from the first visit to the finished result.
Permissions for a new roof in Swanley
Planning law differs across the UK. For a home in Swanley, it is the England rules below that count, and we check them with the council ahead of any 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
A visit to your home
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.
Quote in writing
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
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 Swanley property.
The work itself
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
Questions about a new roof in Swanley
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.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
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.
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.
How much will a new roof cost in Swanley?
As a guide, expect to pay £7,800–£17,000 including VAT for a new roof in Swanley. That range is adjusted for the South East, which runs about 12% above 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.
