The honest answer is that the cost of a new roof varies considerably depending on size, material, complexity and what is found once the old covering is stripped. That said, there are typical ranges that help you sense-check quotes and budget realistically before you speak to a roofer.
As a rough guide, a new pitched roof in this part of England currently costs anywhere from around £70 to £150 per square metre installed, depending on material and complexity. A straightforward concrete-tiled roof at the lower end of complexity sits towards the lower part of that range; a natural slate roof with lead valleys, a chimney and multiple hips sits towards the upper end or above it. These are installed figures covering labour, materials, fixings and standard flashings, but not scaffolding, skip hire or structural repairs.
For a typical single-storey rear extension roof of around 25 to 40 square metres, total project costs often fall between £3,000 and £7,000 all in. Larger or more complex roofs cost proportionally more. A full re-roof of a detached house with a straightforward hip roof and no complications might run from £8,000 to £15,000 or more depending on size and material.
The tile or slate you choose is one of the biggest single variables in the overall price.
Imported slate from Spain or Brazil is available at a lower material cost than Welsh slate, but the quality is more variable and some imported products have a shorter track record in UK conditions. The difference in longevity over 40 or 50 years can offset the initial saving.
Several factors reliably increase the final cost of a new roof project above the basic per-square-metre estimate.
Roof complexity. A simple gable-ended or mono-pitch roof has no hips, no valleys and fewer junction details. Every hip, valley, dormer, roof light, chimney or abutment wall adds time, additional lead or proprietary flashing material, and extra detailing work. A roof with four hips, two dormers and a chimney will cost materially more per square metre than a plain rectangular slope, even using the same tile.
Access and scaffold requirements. Scaffolding cost on a straightforward single-storey extension is typically £500 to £1,000. On a full two-storey house with complex roof geometry it can reach £2,000 to £3,500 or more. If access to neighbouring land is needed to erect scaffold safely, that adds a negotiation and sometimes a licence cost. Scaffold is not optional on most roof replacements and should be included in any complete quote you receive.
Structural condition. Once a roof is stripped, the full condition of rafters, purlins, ridge board and wall plate becomes visible. Rafter ends at the eaves are a common location for rot because they sit close to the gutter and take any overflow. Replacing a run of rafter feet, sistering additional timber to a weakened rafter, or installing a new ridge board all add cost. A roofer who includes a contingency allowance for structural work is being realistic; one who quotes a fixed price without ever having seen the structure exposed should be questioned on this.
Chimney and flashing work. Repointing a chimney stack or rebuilding a chimney pot is most economically done during a re-roof when the scaffold is already in place. If the lead flashing around the stack needs replacing as well, that adds both material and time. Code 4 lead step and cover flashing on a standard chimney might add £400 to £700 to the overall cost depending on stack size and number of faces.
Waste disposal. Old tiles, broken slates and stripped underlay must be removed from site. A skip large enough for a single-storey re-roof typically costs £200 to £400 depending on local hire rates and tip charges. Confirm whether this is included in the quote or charged separately.
Choosing a simpler roof form for a new extension reduces cost. If you have a choice between a hipped roof and a simple lean-to or gable-ended roof for a garden room or outbuilding, the simpler shape will cost less to cover and less to maintain.
If the existing tiles on a re-roof are in good condition and the failure was in the underlay and battens rather than the covering itself, it is sometimes possible to strip, renew the underlay and battens, and re-lay the original tiles. This does not always work - tiles crack during stripping and stock can be short - but it can significantly reduce material costs on a clay or natural slate roof where the tiles themselves are valuable.
Timing the work during quieter periods rather than in summer, when demand for roofing is high, may also give you more flexibility on price and scheduling.
Any quote for a new roof should specify the tile type and manufacturer, the underlay specification, the batten size and treatment, how flashings will be formed and in what material, whether scaffold and skip are included, and what happens if structural repairs are needed once stripping begins. A quote that lists only a total figure without these details is difficult to compare fairly against others and makes disputes about scope harder to resolve if something unexpected comes up.
Ask for the square metreage being quoted so you can cross-check the rate. If two quotes use the same material and the per-square-metre rates are very different, ask each roofer to explain what accounts for the difference.
