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.

We offer a new roof throughout London, from Brent, Islington, Westminster and Bexley to the smaller places in between. Each project starts with a free survey at your home and ends with a written figure, fixed for the work you choose. Because London is in England, we work to the planning system and building standards used there, and guide prices for London run at £9,100–£19,500 including VAT.

How much does a new roof cost in London?

In London, guide figures for a new roof sit at £9,100–£19,500, VAT included. We set them using rates for London, currently about 30% above the national guide. The table shows what pushes a project towards either end of the range; your own price is set after a free survey.

Fibre cement or synthetic slateA lighter, lower-cost alternative to natural slate with a similar appearance.
Dry-fix ridge and vergeMechanically fixed ridges and verges that need far less mortar upkeep.

Homes in London

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.

London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.

Planning and building rules in London

Which rules apply depends on where you live. For London, the answer is England, and the points below reflect that; we verify them with the council before quoting.

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?

  1. 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.

  2. Price and scope agreed

    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.

  3. 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.

  4. On site to finish

    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.

Frequently asked 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.

What happens if it rains during the work?

We strip the roof in sections and only remove as much covering as we can replace or protect the same day. New breathable membrane goes on straight after stripping, which keeps most rain out, and we sheet exposed areas at the end of each day and before forecast showers. If heavy rain or high winds are forecast, we pause work. The house is never left open.

How long will a new roof last?

A well-installed roof lasts for decades. Concrete tiles typically last around 50 years or more, clay tiles longer, and natural slate can last a century with proper upkeep. Lifespan depends on the quality of materials, fixings, ventilation and leadwork, and on how exposed the roof is. Keeping gutters clear and fixing slipped tiles quickly helps it reach its full life.

Can I stay at home during the work?

In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.

How much will a new roof cost in London?
