A full roof replacement in Kent costs £4,800-£7,500 for a 3-bed semi in concrete tile, or £6,500-£10,000 in clay plain tile. Cost drivers are chimney count, roof complexity, scaffold access and deck condition. Upgrading to clay adds around £2,000 but doubles the roof's service life.
The most common question we get before any survey is: how much is this going to cost me? It's a fair question, and the honest answer is that it depends — but not in an evasive way. Roof replacement costs in Kent vary based on five factors that are all measurable before work begins: property size, roof pitch, tile material, scaffold requirements, and whether there are complicating features like chimneys, dormers or conservation area requirements.
This guide gives you realistic 2025 price ranges for the most common scenarios we encounter across Ashford, Folkestone, Canterbury, Maidstone and the surrounding Kent towns.
These are the ranges we quote in practice across our east Kent coverage area. All prices include scaffold, strip and disposal of old materials, new underlay, new battens, new tiles and ridge. They assume standard access and no structural repairs.
| Property Type | Tile Spec | Typical Cost |
|---|---|---|
| 2-bed terrace / flat | Concrete interlocking | £3,500 – £5,500 |
| 3-bed semi-detached | Concrete interlocking | £4,500 – £7,000 |
| 3-bed semi-detached | Clay tile | £5,500 – £8,500 |
| 4-bed detached | Concrete interlocking | £7,000 – £11,000 |
| 4-bed detached | Clay tile | £9,000 – £14,000 |
| Period / conservation property | Clay plain tile or natural slate | £8,000 – £18,000+ |
The wide ranges reflect real variation in roof complexity. A straightforward rectangular pitch on a 1960s Bockhanger semi costs less to strip and re-tile than a 1930s semi with a hipped section, a chimney stack and a valley between two rear dormers. Both are 3-bed semis on paper.

Book Free SurveyEach chimney stack adds £500–£1,500 to a re-roof cost, depending on its size and condition. The lead flashing at the junction between the chimney and the roof slope must be stripped and replaced as part of a proper re-roof — it cannot be left on a new tile surface. If the chimney itself needs repointing or has structural issues, those are separate costs identified at survey.
A hip — where a sloping plane meets another rather than terminating in a gable end — adds complexity and waste to the tiling operation. Hipped roofs typically add 15–25% to the tile cost versus a straightforward gable-ended roof of the same footprint.
Properties in Canterbury's city centre conservation area, Tenterden's High Street conservation area, or the Wye valley conservation zones are required to use appropriate traditional materials on visible slopes. Reclaimed or reproduction clay plain tiles, natural Welsh slate or approved modern clay can add £1,500–£4,000 to material costs compared with standard concrete interlocking tile. We handle material sourcing and advise on planning requirements.
A full re-roof should always include new battens and underlay — the secondary waterproofing layer under the tiles. Some roofers quote to re-tile only (cheaper on paper but not a proper re-roof). If existing battens are rotten or the felt underlay has perished, cutting this corner leaves you with a new tile surface on a degraded structure underneath. All our re-roof quotes include full batten and underlay replacement as standard.
Standard scaffold for a 3-bed semi runs £600–£1,000 and is included in our quotes. Unusual access situations — properties backing onto roads requiring a traffic management permit, listed buildings needing specialist scaffold, cliff-top properties in Folkestone — add cost that is assessed at survey.
Not every deteriorating roof needs full replacement. The decision comes down to the tile's remaining lifespan and the extent of any underlying damage.
Repair makes sense when: the tile system is less than 25 years old, fewer than 10-15% of tiles have slipped or cracked, the battens and underlay are sound, and the failures are localised (one valley, one chimney flashing, a section of ridge).
Replacement makes sense when: the tile system is concrete interlocking from the 1960s-80s and nail sickness is systemic across the roof, the underlay has perished and is no longer providing secondary waterproofing, or repair costs in the last 3-5 years are approaching 30-40% of replacement cost. At that point you're spending money deferring an inevitable job.
On the Bockhanger, Stanhope and Kingsnorth estates in Ashford, and on equivalent 1960s-80s estates across east Kent, we regularly survey roofs where the homeowner has been patching for years at costs that would have funded half the re-roof. A proper survey tells you which side of this line you're on.

Book Free SurveyIn practical terms, yes — but probably not as a direct return on cost. A new roof removes a negotiating point for buyers and satisfies mortgage lenders who would otherwise require work before releasing funds. For properties where the existing roof is in poor condition, a re-roof often makes the sale possible at all. For properties where the roof is borderline, it removes uncertainty. The 10-year guarantee we provide on all re-roof work also transfers to a new owner, which is a tangible asset in a sale.
Whether the investment makes more sense before or after a sale depends on your position. It's worth taking advice from your estate agent alongside getting a roofing quote — they'll tell you what the roof condition is likely to cost you on the asking price or in buyer negotiations.
Phone quotes and online calculators give you a range. An accurate quote requires a physical survey: measuring the roof area, assessing the pitch, checking the tile condition from the roof surface (not just the ground), inspecting the valley, chimney flashings and ridge, and looking at the underlay condition where accessible. This takes 30-60 minutes and is the only way to give you a number you can rely on.

Ashford's housing stock spans five decades of construction: Victorian and Edwardian terraces in Newtown and the older town streets, 1930s semis in Kennington and Willesborough, post-war and 1960s estates at Bockhanger, Stanhope and Park Farm, and more recent development across the southern suburbs.
Each era presents different characteristics. Victorian clay tile on period properties requires matching reclaimed material and lime mortar at any repointing work. 1960s concrete interlocking tile on the estates is now 50-65 years old with corroded nail fixings on most unmodified properties. Understanding which housing era a property belongs to is the starting point for any assessment.
These estates are Ashford's highest-volume source of roofing work. The 1960s-70s concrete interlocking tile stock is now 50-65 years old. Nail sickness is present on the majority of unmodified properties. If you live in one of these areas and have not had roofing work in the last 15 years, a free assessment is worthwhile.
The Victorian terraces in Ashford's Newtown area and the older streets around the town centre require period-appropriate specification: reclaimed or reproduction clay tile, lime mortar at chimney repointing, and conservation-aware approach to any work on visible elevations.

We are a family-run roofing business based in Ashford, covering the town and the surrounding Kent area. We have been working on roofs in this area since 2003. Every job is carried out by our own employed team — we do not subcontract labour. The people who quote are the people who work.
We are registered with the National Federation of Roofing Contractors (NFRC). Our registration can be verified at nfrc.co.uk. We carry £5m public liability insurance on every job. Our insurance certificate is available on request before any work starts. All re-roofing work carries a written 10-year workmanship guarantee. Lead flashing work is guaranteed for 10 years. The guarantee is transferable to a new owner if the property is sold.
We cover Ashford and a broad area of the surrounding Kent countryside: Folkestone, Hythe, Canterbury, Maidstone, Tenterden, and the villages across the Weald and Romney Marsh. Emergency cover is available 24 hours a day, 7 days a week. Call 01233 877 146 for any roofing emergency. For non-urgent work, we aim to survey within 5-7 working days and have the quote in writing within 48 hours of the survey.
We do not charge for call-outs or surveys. Every job gets a written quote before a single tile is moved. The quoted price is the price on the invoice unless we identify and agree additional scope with you during the work. For re-roofing projects where deck condition is unknown before stripping, we include a clear provisional allowance for batten replacement rather than presenting you with a surprise on invoice.

£4,800-£7,500 for a 3-bed semi in concrete tile, or £6,500-£10,000 in clay plain tile. A 4-bed detached runs £7,500-£12,000.
Chimney count, roof complexity (valleys, dormers, hips), scaffold access difficulty, and deck condition discovered on stripping are the main cost drivers.
Clay adds around £2,000 to a semi but doubles service life to 80-100+ years. For long-term owners the lifecycle cost strongly favours clay; for short-term owners it may not.
3-5 working days for a standard 3-bed semi, 5-7 days for a larger detached, and 7-10 days for complex period properties with multiple chimney stacks.
