Indicative market range — UK planning-data pipeline in development

Data refreshed September 2026

The short answer: a typical roof replacement in London costs around £10,200, with half of all projects landing between £6,500 and £16,500. If a quote falls well outside that range, it isn't automatically wrong — but it deserves an explanation you can understand.

How to use this roof replacement range

The middle half of the published sample spans £6,500 to £16,500. That is a 98% spread around the median, so the details of your scope matter more than the label on the project.

What this project can cover

A roof replacement generally covers removal, the new roof covering, underlayment, flashing, and installation; access and scaffolding can materially change the total.

What may sit outside it

Rotten decking, structural repairs, insulation, gutters, solar removal, and interior water damage may be separate line items.

Use your quote to test the range

  • Ask for the roof area, material grade, and expected service life.
  • Get a per-unit price for replacement decking.
  • Confirm who handles permits, disposal, and weather protection.

This guide is an indicative market benchmark, not a sample of permit filings. Use it as an early planning range and replace it with local quotes as your scope becomes clear.

Before you spend on a roof replacement

💸 What drives the cost

  • Roof area, pitch and access (scaffolding can be 10–20% of the job)
  • Material: asphalt/felt shingle vs tile vs slate vs metal spans a 3–4× price range
  • Deck condition: rotten boards or joists discovered after strip-off drive most overruns

✂️ How to spend less

  • Quote in the off-season (late autumn/winter where climate allows)
  • Replace when 20–30% worn rather than after leaks — water damage repair costs more than the roof
  • Ask for a per-board price for deck repairs up front, so discoveries aren't priced under duress

🚩 Red flags when hiring

  • Storm-chaser door knockers offering to "handle your insurance claim"
  • No fall-protection/scaffold plan — it signals an uninsured crew

Questions people ask

How much does a roof replacement cost in London?

Our indicative market range for London puts the median around £10,200, with typical projects falling between £6,500 and £16,500. This is market guidance, not filing-derived data, and is labelled as such.

Are these figures quotes?

No. These are indicative market ranges, not contractor quotes. Treat the range as planning guidance and a sanity-check against the quotes you receive.

Why is the range so wide?

Because identical-sounding projects legitimately differ in size, specification and site conditions. That is why we publish the 25th percentile, median and 75th percentile instead of a single misleading "average" — you can see where a quote sits in the real distribution.
