How Much Does a New Roof Cost in Exeter in 2026?

Replacing a roof is a major investment, so it is understandable that cost is one of the first things homeowners want to know.

The difficulty is that there is no fixed price that applies to every property. A straightforward roof replacement on a small terraced house will cost considerably less than work on a large detached property with several roof sections, chimneys or restricted access.

As a rough national guide, 2026 estimates place the average roof replacement at around £8,000, with wider figures ranging from approximately £4,000 to £19,000. Gable, hip and flat roofs each have different typical price ranges. These figures should only be treated as a starting point, as an accurate price requires a proper inspection of the property.

At KG Roofing SW Ltd, we provide clear, no-obligation quotations for new roofs and roof replacements across Exeter and the surrounding areas. This guide explains what is likely to affect your quote and what you should expect to be included.

Typical New Roof Prices in 2026

Published national figures provide the following broad estimates:

Type of roof	Typical national price range
Gable roof replacement	£7,000 to £16,250
Hip roof replacement	£9,250 to £18,000
Flat roof replacement	£2,800 to £7,500
New roof structure	£6,500 to £20,000 or more

These are general estimates rather than prices for a specific Exeter property. The final cost will depend on the roof’s size, shape, condition, materials and accessibility.

A smaller and relatively simple roof may sit towards the lower end of the range. Larger roofs, natural slate finishes, extensive timber repairs or complicated access can push the price higher.

What Affects the Cost of a New Roof in Exeter?

Two properties may look similar from the road but require very different levels of work. Several factors need to be considered before a reliable quotation can be prepared.

The Size and Shape of the Roof

A larger roof requires more materials and more time to complete.

The shape also matters. A simple roof with two straightforward slopes is generally quicker to work on than one with multiple sections, valleys, dormers or extensions. Chimneys, roof windows and solar panels can also increase the amount of labour involved.

Your Choice of Roofing Material

Concrete tiles, clay tiles and natural slate all vary in price, appearance and weight.

The right choice will depend on your property, budget and the finish you want to achieve. In some cases, matching the existing roofs nearby may also be important, particularly on terraced homes or properties in visually sensitive parts of Exeter.

KG Roofing installs pitched slate and tile roofs as well as modern flat roofing systems, including felt, EPDM rubber and GRP fibreglass. You can learn more about our new roofs and roof installation services before arranging a quotation.

The Condition Beneath the Existing Roof

It is not always possible to see the full condition of a roof from outside.

Once the old tiles or covering have been removed, damaged battens, boards or structural timber may be discovered. Some roofs only need a new covering and underlay, while others require more extensive work before the new materials can be installed safely.

A good roofing quotation should explain how unexpected defects will be handled, rather than leaving you uncertain once the project has started.

Scaffolding and Access

Safe access is an important part of any roof replacement.

The cost can vary depending on the height of the building, whether the property is detached or terraced, how close it is to the road and whether there is clear access around the house.

Homes on narrow streets, properties with conservatories and buildings with limited rear access may require a more carefully planned scaffolding arrangement.

Chimneys, Leadwork and Roof Details

Chimneys and the areas where different parts of a roof meet need to be properly sealed against rain.

If lead flashing, chimney pointing or valley sections need replacing, this will add to the overall cost. However, dealing with these areas during the roof replacement is usually more sensible than leaving worn materials in place around a brand-new roof.

Insulation and Ventilation

A roof replacement is a good opportunity to check whether the roof space is properly insulated and ventilated.

Poor airflow can allow moisture to build up, while inadequate insulation may contribute to unnecessary heat loss. These issues should be considered as part of the complete roofing system rather than treated as an afterthought.

Can the Roof Be Repaired Instead?

Not every leaking or damaged roof needs to be completely replaced.

A targeted repair may be enough where the main roof is still in reasonable condition and the problem is limited to an area such as:

• A small number of broken or slipped tiles
• Damaged ridge tiles
• Worn lead flashing
• A localised flat roof leak
• Minor storm damage
• A problem around a chimney or roof junction

A full replacement may be more cost-effective where leaks keep returning, large sections have deteriorated or repeated repairs are no longer providing a lasting solution.

Our approach is to assess the condition of the roof and explain the practical options. Where a professional repair is likely to give the roof several more years of reliable service, replacement may not be necessary.

What Should a New Roof Quote Include?

When comparing roofing quotes, it is important to look beyond the final figure.

A detailed quotation should make it clear what work is being carried out and what materials are being used. Depending on the project, it may include:

• Scaffolding and safe access
• Removal of the existing roof covering
• Disposal of old roofing materials
• New underlay, battens, tiles or slate
• Repairs to damaged timber
• Ridge tiles, valleys and leadwork
• Guttering, fascias or soffits where required
• Labour and expected timescales
• Any applicable workmanship guarantee

A lower quote is not always better value if key parts of the work have been left out. Clear pricing helps you compare quotations fairly and reduces the risk of unexpected additions later.

Will Planning Permission Be Required?

Replacing a roof with a similar design and finish will not normally involve the same planning process as changing its shape or adding a large roof extension. However, additional restrictions can apply to listed buildings and homes within conservation areas.

Exeter City Council advises homeowners to seek appropriate guidance where work may affect a listed property or conservation area. Roof alterations, roof lights and changes to the shape or appearance of a roof may require additional consideration or consent.

This is particularly worth checking if you own an older or historic property and plan to change the roofing material, roofline or external appearance.

How Long Does a Roof Replacement Take?

Many standard domestic roof replacements can be completed within several days to around a week, although larger or more complicated projects may take longer. Published cost guidance also estimates that many replacements take up to a week, depending on the roof’s size and complexity.

The weather can affect the schedule, especially during periods of heavy rain or strong winds. Before work begins, your roofer should provide a realistic timeframe and explain how the property will be protected throughout the project.

Is a New Roof Worth the Cost?

A new roof is a significant expense, but continuing to repair a badly deteriorated roof can become costly and disruptive.

A properly installed replacement provides dependable weather protection, improves the appearance of the property and gives you greater confidence during periods of heavy rain and wind. It also gives the roofer an opportunity to address worn underlay, damaged timber, poor ventilation and other issues hidden beneath the existing covering.

The key is establishing whether replacement is genuinely needed and making sure the proposed work suits the property.
