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.
If you have a new roof on your list for a property in Greenwich, we can help from the first measurements to the final clean-up. For a typical home, plan for 1–2 weeks on site, plus scaffolding time, though larger or more complex jobs take longer. We cover postcodes SE3, SE7, SE10 and SE12 and nearby Blackheath, Canary Wharf and Blackwall, and every quote we send is fixed for the scope described in it.

What should you budget for a new roof in Greenwich?
No two jobs cost exactly the same, but the ranges below give a fair picture of a new roof in Greenwich. Pricing for London runs about 30% above the national guide, and the overall guide is £9,100–£19,500 with VAT included. We'll confirm your figure after surveying the property for free.
| Type of job | What it usually involves | Guide in Greenwich |
|---|---|---|
| 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 |
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
- Condition of rafters, fascias and other timbers
- Chimneys, leadwork and roof windows to rework
What’s included?
- Survey of the covering, timbers, chimneys and loft ventilation
- Stripping old tiles or slates, battens and felt in stages
- 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
- Waste removal by skip and a clean site on completion
What are homes like around Greenwich?
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.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
Building traditions across London also raise conservation and planning questions, so we check those for a new roof in Greenwich at the survey stage.
Planning and building rules in Greenwich
Greenwich 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.
How does the job run?
Survey and measure
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new roof.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Finish and handover
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.

Frequently asked questions
How much does a new roof cost?
Re-roofing a typical 3-bed semi costs £9,100–£19,500, 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.
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.
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.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
