"How much will a new roof cost?" is almost always the first question Bath homeowners ask us — and rightly so. It's one of the largest investments you'll make in your property. The honest answer is that costs vary considerably, but this guide gives you realistic, Bath-specific price ranges based on over 35 years of working on everything from Victorian terraces to Grade I listed Georgian townhouses.
What Affects the Cost of a New Roof?
Several factors combine to determine the final price. Understanding them helps you assess quotes accurately and avoid surprises once work begins.
- Roof size — measured in square metres; the single biggest driver of cost
- Pitch and complexity — steeper roofs and those with multiple valleys, dormers, or hips require more labour and scaffolding
- Materials — natural Welsh slate costs roughly twice as much as concrete tile but is often required in conservation areas and around listed buildings
- Scaffolding and access — a tall or awkward roof adds significantly to the overall cost
- Condition of existing timbers — rotten or undersized timbers must be replaced before new coverings are laid
- Heritage and conservation requirements — Bath & North East Somerset Council may specify materials, especially on listed buildings and in conservation areas
- Disposal of old materials — skip hire and tipping fees are usually included in a good quote, but worth confirming
New Roof Costs in Bath by Material
These are installed costs per square metre, including labour, materials, fixings, and underlays. Scaffold, disposal, and any timber repairs are typically quoted separately.
| Material | Cost per m² | Notes |
|---|---|---|
| Welsh / natural slate | £80–£120 | Most common in Bath conservation areas; long lifespan (80–100+ years) |
| Fibre cement / artificial slate | £50–£75 | Good alternative where natural slate isn't required; 30–50 year life |
| Clay plain tiles | £70–£100 | Traditional appearance; often required on Victorian and Edwardian properties |
| Concrete interlocking tiles | £45–£65 | Cost-effective; typically suitable on non-heritage properties |
| EPDM rubber (flat roof) | £50–£80 | Durable, low-maintenance; 20–30 year life with good installation |
| GRP fibreglass (flat roof) | £60–£90 | Seamless, very strong; popular for extensions and dormers |
Typical Total Replacement Costs in Bath
The figures below are for a complete strip and re-roof using natural slate — the most common material on Bath's period housing stock — including scaffold but excluding any timber repairs.
- Small terraced house (40–60 m²): £6,000–£12,000
- Mid-terrace or semi-detached (60–90 m²): £10,000–£20,000
- Detached house (90–130 m²): £15,000–£30,000
- Large detached or heritage property (130 m²+): £25,000–£50,000+
Costs in Bath consistently sit at the higher end of UK national averages. This reflects the prevalence of natural slate, the complexity of Georgian and Victorian roof structures, and the skilled labour required to work sympathetically on historic buildings. A quote that looks much cheaper than these ranges almost always means inferior materials, underqualified labour, or hidden extras.
Additional Costs to Factor In
A thorough quote should itemise these separately so you can compare like for like:
- Scaffolding: £800–£2,500 depending on height, access, and duration
- Rotten or undersized timbers: £500–£3,000+ depending on extent — only visible once the old covering is stripped
- Chimney repairs and lead flashings: £500–£2,000 per chimney
- Lead valleys and abutments: £300–£1,000
- Guttering: often replaced at the same time; guttering replacement typically adds £800–£2,500 for a standard house
- Disposal and skips: usually included, but confirm with your contractor
Repair vs. Full Replacement — Which Do You Need?
Not every failing roof needs a full replacement. Sometimes roof repairs in Bath are all that's needed — replacing a run of broken slates, re-pointing a ridge, or fixing failed flashing can add years to an existing roof for a fraction of the cost.
Signs you may need a full replacement rather than a repair:
- The roof is 40–60+ years old and nearing end of life
- More than 20–25% of tiles or slates are broken, missing, or slipping
- There are widespread leaks or damp patches in multiple rooms
- Significant sagging or movement in the roof structure
- Your roofer has advised against further patch repairs
If you're unsure, we offer free inspections and will always give you an honest assessment — even if that means telling you a repair is all you need right now.
Do You Need Planning Permission for a New Roof in Bath?
In most cases, no — replacing a roof with the same or similar materials is covered by permitted development rights. However, there are important exceptions in Bath:
- Listed buildings always require Listed Building Consent for any roofing work, including like-for-like replacements
- Conservation area properties may need approval if you're changing the roof's appearance — for example, switching from natural slate to concrete tile
- Article 4 Directions apply to many streets across Bath and remove some permitted development rights that would otherwise apply
Bath & North East Somerset Council has some of the strictest planning policies for heritage properties in England. We'll always advise you on what permissions you need before any work starts, and we have extensive experience working within these constraints — including liaising directly with the Council's conservation officers.

How to Get a Fair Quote
Getting multiple quotes is always sensible for a job of this size. Here's what to look for:
- Get at least three written quotes — verbal estimates are not sufficient
- Ensure each quote specifies the same materials (natural vs. artificial slate makes a big cost difference)
- Confirm what's included: disposal, scaffolding, valley lead, and any timber work
- Ask about workmanship guarantees — a reputable roofer will offer 10+ years
- Check the contractor is fully insured and ideally registered with the NFRC (National Federation of Roofing Contractors)
- Be cautious of quotes significantly below the others — quality materials and skilled labour aren't cheap, and a cut-price job often costs more to put right
