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 Mitcham 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 London should budget £9,100–£19,500 including VAT, with work typically taking 1–2 weeks on site, plus scaffolding time.

Roof replacement prices in Mitcham
Here is how the guide price for a new roof breaks down in Mitcham. We start from national figures and adjust for London, which comes out about 30% above the national guide. The resulting range, VAT included, is £9,100–£19,500, and a survey, at no cost to you, firms it up.
| Type of job | What it usually involves | Guide in Mitcham |
|---|---|---|
| Terraced house or bungalow | A smaller pitched roof re-covered in concrete or clay tiles, including scaffolding. | £6,500–£13,000 |
| Typical semi-detached | A 3-bed semi re-roofed in concrete or clay tiles with new membrane, battens and leadwork. | £9,100–£19,500 |
| Detached or natural slate | Larger or more complex roofs, or any roof finished in natural slate. | £15,500–£32,500 |
The main things that change the figure:
- Roof area, pitch and the number of hips, valleys and dormers
- Condition of rafters, fascias and other timbers
- 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
- Repairs or replacement of damaged rafters and fascia boards
- 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
What are homes like around Mitcham?
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
If your house in Mitcham fits one of these patterns, it helps us anticipate what a new roof will involve, though we always confirm the details on site.
Permissions for a new roof in Mitcham
Homes in Mitcham come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
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
Free site survey
First, someone visits your home in Mitcham to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Your fixed price
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.
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 Mitcham property.
Finish and handover
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.
How we work
Roof replacement in Mitcham: questions
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 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 long will a new roof take?
On a typical home, allow 1–2 weeks on site, plus scaffolding time. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
How much will a new roof cost in Mitcham?
As a guide, expect to pay £9,100–£19,500 including VAT for a new roof in Mitcham. That range is adjusted for London, which runs about 30% 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.
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.
