If you are planning a gable roof project, the first question is almost always the same. How much is this going to cost? A gable roof in the UK typically costs between 5,000 and 14,000 pounds, but that range hides a lot of detail. Size, material, region, pitch and the condition of your existing structure can all move the final price by thousands of pounds in either direction.
This guide breaks the cost down properly, so you go into any quote already knowing roughly what to expect.
What is a gable roof, quickly
A gable roof has two sloped sides that meet at a central ridge, with a triangular wall, called the gable end, at each end of the building. It is the most common roof shape in the UK, found on everything from Victorian terraces to modern new builds. Its simple triangular shape is also part of why it tends to cost less than more complex roof designs such as hip roofs.
Average cost by roof size
Cost scales mainly with the surface area being covered. As a rough guide for a straightforward re-roof using standard concrete tiles, here is what UK homeowners typically pay.

| Roof size | Typical cost range |
|---|---|
| Small, up to 40 square metres | 4,500 to 6,500 pounds |
| Medium, 40 to 70 square metres | 6,500 to 9,500 pounds |
| Large, 70 square metres or more | 9,500 to 14,000 pounds or more |
These figures assume a like for like replacement on an accessible roof. New build gable roofs, loft conversions that extend the roof, or any project needing structural work, will usually sit above these ranges.
Cost by material
Material choice is often the single biggest factor in your final price, and it also determines how long the roof will last before you need to think about this again.
| Material | Cost per square metre | Typical lifespan |
|---|---|---|
| Concrete tile | 45 to 65 pounds | 40 to 60 years |
| Natural slate | 90 to 140 pounds | 80 to 100 years or more |
| Composite tile | 60 to 90 pounds | 50 years |
| Metal sheet | 50 to 80 pounds | 40 to 70 years |
Natural slate costs the most upfront, sometimes more than double the price of concrete tile. But once you divide the cost by its expected lifespan, slate often works out as one of the cheapest options per year of use. Concrete tile remains the most common choice in the UK simply because it balances cost and performance well for most homeowners.

Regional cost variation
Labour typically makes up 40 to 50 percent of a roofing quote, and labour rates vary a fair amount across the UK. The same size and material of roof can cost noticeably different amounts depending on where you live.
- London and the South East. Typically 15 to 25 percent above the national average, driven mainly by higher labour and access costs in dense urban areas.
- Midlands and North West. Generally closest to the national average figures quoted above.
- North East, Scotland and Wales. Often 10 to 15 percent below the national average.

What can push a quote higher
Beyond size, material and region, several other factors commonly increase the price beyond the ranges above.
- Steep pitch or difficult access. A steeper roof, or a property that needs extra scaffolding to reach safely, adds labour time and equipment cost.
- Hidden structural damage. Rotten timber or joist damage is often only discovered once the old roof covering is stripped away. A good roofer will flag this as a possible extra cost before starting work.
- Insulation upgrades. Bringing loft insulation up to current Building Regulations Part L standards during a re-roof is common, and adds to material and labour cost.
- Extra roof features. Chimneys, valleys, skylights or dormer windows built into the gable all add complexity and cost.
New roof versus repair
Not every roofing job needs a full replacement. As a general rule, if repair costs are creeping close to 30 to 40 percent of what a full re-roof would cost, or your roof is already past around 80 percent of its material’s expected lifespan, full replacement usually offers better long term value than another round of patch repairs. Our guide on how long a gable roof should last goes into this in more detail, including the warning signs worth watching for.
How to read a quote properly
A clear, trustworthy quote should separate out labour, materials, scaffolding, waste removal and VAT as individual line items. If a quote arrives as a single lump sum with no breakdown, it is reasonable to ask for an itemised version before you agree to anything. This also makes it much easier to compare multiple quotes fairly, since a cheaper headline price sometimes hides missing items like scaffolding or waste removal that another roofer has already included. For a full walkthrough of what to look for, read our guide on reading a roofing quote.
Ways to manage the cost
- Get at least three quotes so you have a genuine basis for comparison, not just one number to trust blindly.
- Time non-urgent work for late autumn or winter, when some roofers offer lower prices during quieter months.
- Ask whether reusing sound existing timber, where safe to do so, could reduce material cost.
- Check whether your home insurance covers any portion of the work, particularly if storm or wind damage caused the need for repair.
Frequently asked questions
How much does a gable roof cost on average in the UK?
Most homeowners pay between 5,000 and 12,000 pounds for a standard gable roof replacement, depending mainly on size and material. Larger roofs, premium materials like natural slate, or properties needing structural repair can push this higher.
Is a gable roof cheaper than a hip roof?
Generally yes. A gable roof is simpler to frame than a hip roof, which typically makes it around 10 to 15 percent less expensive for a comparable size and material. See our gable versus hip roof comparison for a fuller breakdown.
How long does a gable roof replacement take?
A typical residential gable roof takes 5 to 10 working days from strip out to final inspection, weather permitting. Larger or more complex roofs can take longer.
Do I need planning permission for a new gable roof?
A like for like replacement usually does not need planning permission. Changes to the roof shape, height, or the addition of dormers or extensions, often do. Always check with your local council before starting significant structural changes.
