How the calculator works
The calculator estimates the area of your roof from your property type and bedrooms, applies a typical installed price per square metre for your chosen roof material, then adds scaffolding and — if you need it — the cost of stripping and disposing of the old roof. It's a quick way to get into the right ballpark before a roofer measures up. For an exact price, request your free survey and fixed quote.
This roof replacement calculator gives a budgeting range, not a fixed price. Your real figure depends on a measured survey.
What each question means
- Property type & bedrooms — together these estimate how big your roof is.
- Roof type — tiles, slate or flat roof; this sets the price per square metre.
- Storeys / access — taller and harder-to-reach roofs need more scaffolding.
- Strip the old roof? — a full re-roof usually means removing the old covering first.
- Known issues? — leaks, sagging or storm damage may mean extra repairs your roofer will confirm.
