One of the first questions homeowners ask when they suspect their roof is failing is: how much is this going to cost me? It's a fair question, and the honest answer is: it depends — mostly on the size of your roof. A small terrace and a large detached house can vary by tens of thousands of pounds for the same material. This guide breaks down what a new roof really costs in Hampshire in 2026, how house size and material choice change the figure, and what you should expect to get for your money when you ask CMW Repairs for a quote.

Typical New Roof Costs in Hampshire (2026)

The table below gives realistic 2026 price ranges for the most common roof types. The lower end reflects smaller mid-terrace properties with straightforward roofs; the upper end reflects larger detached or four-bedroom homes with complex pitches, multiple elevations, dormers, or chimney stacks. Larger houses with very complex roofs can exceed these figures. All ranges include materials, labour, scaffolding, waste disposal and VAT.

Roof Type Typical Cost Range (Supply & Fit) Expected Lifespan
Concrete interlocking tiles £8,000 – £18,000 30–50 years
Clay plain tiles £12,000 – £25,000 60–100 years
Natural Welsh slate £18,000 – £40,000+ 75–100+ years
Fibre cement slate (artificial) £10,000 – £20,000 30–40 years
GRP fibreglass flat roof £2,500 – £8,000+ 25–50+ years
Felt flat roof (torch-on) £1,500 – £4,500 10–15 years

These are guidelines, not guarantees. The biggest single factor driving price is the roof area — a larger house simply needs more material, more labour days and more scaffolding. To give a real-world example, a natural Welsh slate re-roof we recently quoted on a larger Hampshire home came in at around £38,000. The same material on a small terrace might be closer to £18,000. Material costs have also risen sharply in recent years, so any prices you find in older articles are almost certainly out of date. The only way to get an accurate figure is a proper site visit and written quote.

Why House Size Makes Such a Big Difference

Roofing is priced by area (in square metres) plus fixed costs for scaffolding and waste. A three-bedroom mid-terrace might have a roof of 70–90 m², whereas a four-bedroom detached house with a hipped or L-shaped roof can easily exceed 180–220 m² once you include the garage and any extensions. That means more tiles or slates, more battens, more felt, more lead flashing, more ridge tiles — and several more days of labour for a team of roofers.

Complexity matters just as much as raw size. A simple gable-to-gable pitched roof is quick to strip and cover. A roof with valleys, hips, dormers, multiple chimney stacks, abutments against neighbouring properties or Velux openings takes significantly longer because each junction needs careful lead work and detail. Two houses the same size can easily be £3,000–£6,000 apart on price once complexity is factored in.

Concrete Tiles: The Most Common Choice in Hampshire

The majority of homes built in Southampton, Eastleigh, and across Hampshire from the 1960s onwards were roofed with concrete interlocking tiles. They're robust, widely available, and the most cost-effective option for a full re-roof. A typical three-bedroom semi-detached house in concrete tile sits around £10,000–£14,000 in 2026; a larger four-bedroom detached with a more complex roof can comfortably reach £16,000–£18,000 or more. Prices include all materials, labour, scaffolding, and licensed disposal of old tiles.

Concrete tiles have a lifespan of around 30 to 50 years, so if your home was built in the 1970s or 80s, there's a good chance you're approaching the end of the original roof's life.

Clay and Natural Slate: Premium Options Worth the Investment

If your property is older — particularly a Victorian or Edwardian home in areas like Shirley, Portswood, or Winchester — you may have original clay or slate tiles. These premium materials cost significantly more to replace like-for-like, but the lifespan justifies the investment. Natural Welsh slate, fitted properly, can last well over a century.

Slate is the most expensive pitched-roof option, and prices scale quickly with size. A small terraced house in natural Welsh slate might start around £18,000–£22,000, a standard semi-detached often lands in the £25,000–£32,000 range, and a larger detached house with complex elevations can push past £38,000 — we recently quoted one at exactly that figure. The material itself is a significant part of the cost, and labour is slower than tile work because slates are lighter, nailed individually and require careful sorting.

Clay tiles are also popular in conservation areas where planning requirements restrict what you can use. We always recommend checking with your local council if you're unsure whether permitted development rules apply to your roof.

Artificial fibre cement slate is a cost-effective middle ground. It looks similar to natural slate, costs roughly half as much, and still offers a 30 to 40-year lifespan. For many Hampshire homeowners, it's the right balance between aesthetics and budget.

Flat Roofs: GRP vs Felt

Extensions, garage roofs, and bay window tops are the most common places you'll find flat roofing in Hampshire homes. Flat roof prices depend heavily on surface area — a small porch or bay is a fraction of the cost of a full extension roof. We've covered the material choice in more detail in our GRP vs felt flat roof comparison, but in short: GRP fibreglass costs more upfront but lasts two to three times longer than traditional felt and requires virtually no maintenance. Over a 20-year period, it almost always works out cheaper.

What Affects the Final Price?

The figures above are starting points. Here are the key factors that push a quote higher or lower:

  • Roof size (the biggest factor): Roofing is priced per square metre, so a larger house simply needs more of everything. Doubling the roof area can easily double the total price.
  • Roof complexity and pitch: Valleys, hips, dormers, multiple pitches and steep angles all take longer to fit safely, and often require more lead work at junctions.
  • Scaffolding: Almost all full re-roofs require scaffolding for safety compliance. For a typical Hampshire home this usually adds £1,500 to £3,000 depending on the building's height, footprint and access.
  • Condition of the roof deck: If the sarking felt or battens underneath are rotten or damaged, they need replacing. This adds cost but is essential — skipping it is a false economy.
  • Chimney stacks: Any chimneys that pass through the roof need their flashing inspected or replaced. Lead flashing work adds to the overall cost but prevents water ingress at one of the most vulnerable points.
  • Access and location: Properties on busy roads, with restricted access, or in conservation areas may require additional planning or logistics costs.
  • Waste disposal: Old tiles are heavy. Responsible disposal of the old roof material is included in every CMW quote and handled by licensed waste carriers.

What's Included in a CMW Quote?

When you ask CMW Repairs for a roofing quote, we visit the property, inspect the roof (including the loft if accessible), and provide a written, itemised quote that covers:

  • Full strip of the existing roof covering
  • Inspection and replacement of any damaged battens or deck boards
  • New breathable roofing felt or membrane
  • Supply and installation of your chosen tile or slate
  • Ridge tiles, verge work, and hip tiles where applicable
  • Lead or code 4 flashing around any chimneys, valleys, or abutments
  • Scaffolding erection and dismantling
  • Full clean-up and licensed waste disposal
  • 15-year workmanship guarantee

There are no hidden extras. If we discover additional problems once work is underway — rotten timbers, for example — we'll always discuss them with you before proceeding and provide a revised cost in writing.

Should You Get Multiple Quotes?

Yes. We'd always recommend getting at least two or three quotes from local roofers for a significant job like a full re-roof. Be cautious of quotes that are significantly cheaper than others — they may be cutting corners on materials, skipping scaffolding (which is both dangerous and illegal), or not including waste disposal.

Look for roofers who are members of Checkatrade or MyBuilder with verified reviews, carry public liability insurance (ask to see the certificate), and provide a written guarantee on their workmanship.
