Roof Repair Costs UK — Tile Replacement, Ridge Tiles, Lead Flashing and Flat Roof Repair Pricing Guide (2026)

UK Roof Repair Costs at a Glance (2026)

The table below covers the most common roof repair types. All prices are guide figures for a typical domestic property in England and Wales; London and the South East typically run 20–35% higher. Scotland and Northern Ireland can be 10–15% lower.

Single Tile Replacement: £80–£200

Replacing one or two broken, slipped, or missing tiles is the most common domestic roofing call-out. The price range is wide because the biggest variable is access. A single-storey extension with safe ladder access at £80–£100 is a fundamentally different job to the same tile repair on a third-floor dormer where a scaffold tower is required.

The tile itself costs £2–£50 depending on type — concrete interlocking tiles are cheap and widely available, but matching an unusual profile or a discontinued concrete tile can mean sourcing a reclaimed tile at a premium. Natural Welsh slate is more expensive still. Always check whether a matching tile is available before quoting a repair, or qualify your quote accordingly.

Most roofers charge a minimum call-out of £80–£120 for small repairs regardless of the work involved. This covers travel, van, insurance, and the time involved in getting onto a roof safely. Do not be apologetic about this — explain it as part of your professional service. Clients who balk at a minimum call-out charge are often the same clients who later question every line of a larger invoice.

When you attend a single-tile call-out, always inspect the surrounding area. A client who calls about one broken tile may have five more that are cracked or near-failure. Flagging this, photographing the evidence, and offering a preventative repair at the same visit is good practice — and good business.

Ridge Tile Repointing and Replacement: £300–£1,000

Ridge tile failure is one of the most common roofing problems in the UK. Mortar-bedded ridge tiles are exposed to severe thermal cycling and wind uplift; mortar cracks, the tiles loosen, and in high winds they can become a hazard. A 10-metre ridge on a standard semi-detached house is the most common reference point for pricing.

Mortar repointing only (£300–£500 for 10m)

If the ridge tiles are otherwise sound and sitting correctly, raking out and repointing the mortar beds can extend the life of the ridge by 5–10 years. The mortar used should be a semi-dry sand-cement mix (approximately 3:1 sharp sand to cement) with the joints finished flush to prevent water sitting on the surface. Lime-modified mortars are appropriate for period properties. This work requires scaffolding or a properly footed ladder at the ridge — never allow work from an unfooted ladder at ridge height.

Full ridge tile replacement (£500–£700 for 10m)

Where the existing ridge tiles are cracked, heavily weathered, or mismatched, stripping and relaying with new tiles and fresh mortar beds is the correct approach. Supply and fix for new concrete half-round or angular ridge tiles on a 10m ridge typically falls in this range.

Dry-fix ridge system (£700–£1,000 for 10m)

Dry-fix ridge is now the specification recommended by most tile manufacturers and increasingly expected by building inspectors on full re-roofs. A mechanically fixed ridge with a continuous support tray and ventilated ridge terminal eliminates mortar — removing the primary failure mode. It costs more to install but is effectively maintenance-free. On new-build and full re-roof projects, always specify dry-fix unless there is a specific heritage reason to use mortar bedding.

Lead Flashing Repair and Replacement: £200–£600

Lead flashings seal the junction between a roof covering and a vertical surface — chimney stacks, parapet walls, dormers, and abutments where a lean-to roof meets a main house wall. When lead fails, water enters the building at that junction; the resulting damp can penetrate into the ceiling below, the wall structure, and in the case of chimneys, into the fireside plasterwork.

The £200–£600 range covers individual flashings. A simple abutment step flashing on a porch or flat-roof lean-to sits at the lower end. A complete chimney flashing package — front apron, back gutter, two sets of soakers and stepped flashings — on a wide double chimney stack is at the upper end or beyond.

Common lead flashing repairs

• Chimney front apron: £80–£150. The lead sheet that covers the junction between the front face of the chimney and the roof tiles below it. A common failure point — the lead cracks through thermal fatigue or has been patched with mastic sealant (a temporary fix that lasts two to three years at best).
• Stepped flashing (per metre run): £40–£80. Lead stepped and cut into courses of brickwork along the side of a chimney or dormer, covering the soakers below. Should be Code 4 minimum, with lead wedged and pointed into the mortar joint.
• Back gutter: £100–£200. The lead-lined gutter behind a chimney stack that collects water running down the back of the chimney. Often the most heavily loaded and first to fail. Must have adequate fall and be Code 5 lead.
• Soakers (per roof slope): £60–£120. Individual L-shaped lead sheets under each course of slate or plain tile at an abutment. Must be correctly sized for the tile gauge; the visible stepped flashing sits over them.

Flat Roof Repair Costs: Felt Patch to Full Replacement

Flat roofs cover a significant proportion of UK domestic extensions, garages, and bay window tops. They are more vulnerable to failure than pitched roofs because water does not shed as quickly and tends to sit on the surface. The repair or replace decision depends on the age of the covering, the extent of damage, and whether the deck beneath is sound.

Felt patch repair: £100–£300

A patch repair on a felt flat roof is appropriate only where the covering is otherwise in reasonable condition and the damage is genuinely localised — a blister, a small split, or a puncture. Strip back the damaged felt, clean the deck, apply a new torch-on felt patch with adequate lap (minimum 150mm) onto sound existing felt. Never patch over wet or rotting deck material.

Be honest with clients: a patch on a felt roof over 15 years old is buying time, not solving the problem. Document the age and condition of the overall roof in your job notes and communicate clearly that the patch is not a permanent solution.

Full flat roof re-felt (garage): £800–£3,000

A complete re-felt on a standard single garage (approximately 18–25 m²) using three-layer high-performance torch-on SBS modified bitumen felt typically costs £800–£1,500. A larger double garage or domestic extension (30–50 m²) with upstands, rooflights, and drainage details runs £1,500–£3,000. Prices assume the deck is sound; a rotten OSB or plywood deck adds £15–£25 per m² for replacement.

EPDM rubber flat roof: £50–£80 per m² installed

EPDM (ethylene propylene diene monomer) is a single-ply synthetic rubber membrane that has become the dominant specification for domestic flat roof replacement. It is cold-bonded with adhesive — no open flame required — and a correctly installed EPDM membrane will last 30–50 years. The seams are bonded with specialist tape and adhesive; a fully adhered system on a prepared deck has minimal failure points. At £50–£80 per m² supply and fix, it is cost-competitive with quality felt and significantly more durable.

GRP fibreglass flat roof: £60–£100 per m² installed

GRP (glass-reinforced polyester) is a liquid-applied system that cures to a seamless rigid shell. It is particularly well-suited to roofs with complex upstands, penetrations, or irregular shapes where membrane systems would require multiple taped seams. GRP is extremely durable (25–40 year life) and resistant to foot traffic, making it the preferred choice for walkable roofs and balconies. The higher cost reflects both material price and the skill required for correct application — GRP must be applied within temperature and humidity limits, and mixing ratios are critical to cure. Installers require manufacturer training to access warranty-backed systems.

Chimney Repointing and Rebuild Costs

Chimney stacks receive the harshest weathering of any part of a house. Exposed on all four sides above the roofline, subject to thermal cycling, frost action, and wind-driven rain, even well-built stacks require maintenance every 15–25 years. The access cost is similar whether you are repointing or rebuilding, which is why it is worth carrying out a thorough inspection before quoting repairs only.

Chimney repointing: £300–£800

Raking out and repointing all four sides of a standard chimney stack. The mortar specification matters: pre-1919 soft brick chimneys should be repointed in a lime mortar (NHL 3.5 or similar) not OPC cement, which is too rigid and causes the brick faces to spall. Post-1950 engineering brick stacks can tolerate a semi-hydraulic lime or a gauged cement mortar. Price depends on stack size, number of pots, and how much of the existing mortar requires raking out.

Chimney rebuild: £1,500–£5,000

Where the stack above roof level is beyond repair — severe cracking, structural movement, or mortar joints deteriorated throughout — taking it down to a sound course below the flaunching and rebuilding is the correct specification. The price range is wide: a simple single-flue stack two courses above the ridge line at £1,500–£2,500; a wide multi-flue period stack with decorative corbelling at £3,000–£5,000. New pots and a new flaunching are always included in a rebuild quote; new lead flashings should be quoted as a separate line item even when done at the same time.

Chimney removal and roof reinstatement — where a redundant chimney is taken below roof level and the opening is sealed and tiled over — costs £1,000–£3,000 depending on the size of the chimney and the complexity of the reinstatement. Always check whether building regulations apply for any internal breast removal.

Fascia, Soffit and Guttering: £100–£300 per Section

Fascias, soffits, and guttering are often addressed at the same time as roof work because the scaffold is already up and the access cost is already paid. Replacing roofline components in uPVC is a straightforward job that improves the appearance of the property and eliminates future painted timber maintenance.

£100–£300 per run covers replacing a section of fascia board, soffit board, and guttering on a standard eaves height. A full roofline replacement on a three-bedroom semi — all four elevations — typically costs £2,000–£4,000 including uPVC fascia, soffit, and half-round guttering, completed during the same scaffold hire as a re-roof.

Common materials are 18mm uPVC fascia with vented soffit panel. OGEE or square-profile guttering is popular on period properties. Always check whether the existing rafter feet are sound before boarding over them — rotten rafter ends are a common finding on houses with previously maintained painted timber fascias.

Full Pitched Roof Re-Tile: £5,000–£15,000 for a Semi

A complete re-tile — stripping the existing covering, new underlay and battens, and re-tiling throughout — is the largest single repair cost a domestic roof can incur short of structural rebuilding. For a typical three-bedroom semi-detached with a roof area of 80–100 m², the price range in 2026 is:

• Concrete interlocking tiles: £5,000–£9,000. The most cost-effective specification. New felt underlay (breathable membrane), new treated 25x50mm battens, and new concrete tiles. Widely available, reliable, and the standard choice for most post-1960s domestic re-roofs.
• Clay plain tiles: £7,000–£12,000. More labour-intensive due to smaller format and double-lap requirement. Appropriate for Victorian and Edwardian properties and increasingly specified on new-build premium housing.
• Natural Welsh slate: £9,000–£15,000. The premium option. Thin, lightweight, exceptionally durable (100-year lifespan is realistic), and the only appropriate specification in many conservation areas and on listed buildings. Natural slate requires a more skilled fixer and more time per m², which is reflected in the labour rate.

All the above prices exclude scaffold, which for a semi-detached re-roof typically adds £500–£1,500 depending on the site, access constraints, and hire period. Always itemise scaffold as a separate line in your quote.

Emergency Roof Repair Call-Outs: £150–£350

Emergency call-outs — storm damage, missing tiles causing active ingress, fallen masonry, or a tree branch through a roof slope — command a premium and should be priced accordingly. The call-out charge of £150–£350 covers your attendance and the time to assess and make safe. Repair materials, skip hire, and any additional scaffold are quoted on top.

State your emergency call-out rate clearly in your terms and conditions, on your website, and at the point when a client calls. Out-of-hours rates — evenings and weekends — are typically 25–50% above the standard rate. Clients calling after storm damage are usually not price-shopping at that moment; they want someone reliable who will come quickly and make the property watertight. Emergency call-outs are often the entry point to larger planned repair or re-roof jobs — the client who trusts you in a crisis is likely to call you first when the insurance claim has settled and the full repair is ready to be quoted.

Scaffold Costs: £500–£1,500 for a Semi — When It's Required

Scaffold is not optional on most roofing work above single-storey height. The Work at Height Regulations 2005 require that work at height is properly planned, appropriately supervised, and carried out in a way that minimises risk. Using a ladder to carry out significant repair work on a pitched roof above first-floor height is not, in most cases, an acceptable safe system of work.

For a three-bedroom semi-detached, a standard scaffold with boards at eaves level and a handrail typically costs £500–£900 for a two-to-three week hire period. A larger detached house with hipped roof, or a property requiring scaffold on multiple elevations, is £1,000–£1,500 or more. Weekly extension rates apply if the job overruns or the hire period needs to be extended.

Scaffold is required for:

• Any full or partial re-tile on a pitched roof above single-storey
• Ridge tile replacement or repointing (a ladder to the ridge is not a safe platform for extended work)
• Chimney repointing or rebuild
• Lead flashing replacement on chimney stacks or upper-slope abutments
• Fascia, soffit, and guttering replacement at or above first-floor eaves height

Small patch repairs on a low-pitch or single-storey extension may be completed safely from a properly footed ladder. Always document your risk assessment for any work at height. If a client asks you to skip scaffold to save money, explain clearly that the scaffold is part of your safe system of work and is non-negotiable. A contractor who skips scaffold to win a price comparison is a risk to themselves, their workers, and the client.

Roof Surveys: Drone vs RICS

A roof survey before repair or re-roof work establishes the true scope of what is needed and protects both the roofer and the client from scope creep and disputes.

Drone roof survey: £200–£400

A commercial drone operated by a CAA-authorised pilot captures high-resolution photographs and video of the roof from angles that would otherwise require scaffold. It is an efficient way to assess the overall condition of a roof covering, identify areas of tile failure, check ridge and hip mortar, inspect lead flashings at chimney stacks, and survey flat roofs for ponding or surface deterioration. A drone survey report includes annotated photographs and a written condition summary. It does not replace a physical inspection of the felt underlay or loft space — the drone sees only the surface.

RICS roof survey: £300–£600

A RICS HomeBuyer Report or Building Survey includes a roof inspection as part of a broader property survey. The RICS surveyor assesses the roof from ground level and accessible positions (they do not typically go onto the roof surface) and reports on visible condition and any identified defects. The roof survey cost is included in the overall survey fee rather than charged separately. If a RICS surveyor flags roof defects, clients frequently commission a specialist roofer's report before exchange of contracts.

Signs of Roof Damage Homeowners Should Know

Part of your value as a roofer is helping clients understand what to look for. Including this on your website or in a follow-up email after a quote establishes you as an expert rather than just a contractor. Common warning signs include:

• Missing or displaced tiles. Visible from street level. Even one missing tile allows water entry and accelerates deterioration of the felt below. Do not wait for a leak before investigating.
• Damp patches on ceilings or walls. Interior damp that appears after rain, particularly at chimneybreasts, party walls, or top-floor ceilings below a flat roof. The entry point is almost always higher and further back than the visible damp patch.
• Daylight visible in the loft. Stand in the loft on a bright day and look for light coming through. Any daylight means a gap large enough to admit water. Even small gaps in felt or around rafter feet allow driven rain to enter.
• Sagging or misaligned ridge line. A ridge line that is no longer straight when viewed from the ground may indicate rafter or wall plate movement below.
• Moss and lichen growth. Heavy moss indicates that the tile surface has deteriorated to the point where it is holding moisture. Moss itself does not cause leaks, but its presence on tiles over 20 years old often accompanies underlying felt deterioration.
• Staining around chimney flashings. Brown staining on ceiling plaster near a chimeybreast is almost always a flashing failure rather than a flue or pot issue.

Finding Qualified Roofers: NFRC and Competent Roofer

The UK roofing market has a significant number of operators without formal qualifications, adequate insurance, or a genuine understanding of the current specification requirements. The two most credible accreditation routes for domestic roofers are:

• NFRC (National Federation of Roofing Contractors). The UK's largest roofing trade body. NFRC members have passed a technical assessment, hold appropriate public liability and employer's liability insurance, and are bound by a code of conduct. NFRC membership is recognised by insurance companies, loss adjusters, and specifiers. Members can access the NFRC Guarantee scheme for consumer protection on completed work.
• Competent Roofer scheme. A government-approved competent person scheme that allows registered roofers to self-certify certain types of roofing work under the building regulations without notifying the local authority building control. Particularly relevant for flat roof replacement work, which in many circumstances requires building regulations notification.

If you are an NFRC member or Competent Roofer registered, say so explicitly in every quote. Many clients do not know what these schemes mean until someone explains them. A brief sentence — “As an NFRC member, our work is covered by independent technical assessment and the NFRC consumer guarantee” — can be the deciding factor in a competitive quote situation.

Quoting Guide for Roofers: Materials, Scaffold, Access

A professional written quote is your most important marketing tool. Clients comparing three roofing quotes are, consciously or not, assessing which contractor they trust most. A detailed, clearly structured quote signals competence. A vague single-line price signals the opposite.

What to include in every roofing quote

• Scope of works: specific tiles, felt, batten specification; specific lead code; specific flat roof system including manufacturer name where relevant
• Scaffold: always a named line item with hire period stated and weekly extension rate specified
• Disposal: skip hire or contractor removal; who arranges and who pays
• Exclusions: structural repairs to rafters, deck replacement, internal decoration — these should be explicitly excluded so there is no ambiguity if they are found to be required during work
• Access conditions: ladder access only, or scaffold required; what happens if access is more complex than expected
• Payment terms: deposit, interim payment milestone, final payment on completion; do not bury these in small print
• Warranty: your workmanship guarantee period; manufacturer material warranties where applicable
• Accreditations: NFRC, Competent Roofer, or other scheme memberships

Pricing material costs accurately

Material costs have been volatile since 2022. Always use current trade prices rather than historic figures or rules of thumb. If you are quoting a job more than four weeks out, consider including a materials price validity clause. Roofing materials — particularly lead, which is a commodity metal priced daily — can move significantly between quote and order.

For tiles, use the manufacturer's stated coverage rate for the specific product and pitch combination. Add 10–15% for waste and cutting, higher on natural slate or complex roof shapes. Ordering short and making a second delivery for a handful of tiles costs more in transport and time than the extra material.

Red Flags in Roofing Quotes

As a professional roofer, knowing the red flags that signal a cowboy contractor helps you explain to clients why your quote is structured differently — and why the cheaper alternative may cost them more in the long run.

• Cash only, no VAT receipt. A cash-only quote with no written contract is not a quote — it is an invitation to a dispute. There is no record of what was agreed, no protection for either party, and no recourse if something goes wrong.
• No scaffold on a two-storey pitched roof job. If a quote for re-roofing a two-storey house makes no mention of scaffold, either it is buried in the rate without being declared (a cost risk if the job overruns) or the contractor is planning to work from ladders in conditions where scaffold is required. Neither is acceptable.
• No written quote at all. A verbal agreement for a roofing job of any significant value is not enough. Without a written scope of works, payment terms, and warranty, the homeowner has no legal basis to challenge substandard work.
• Large upfront deposit (over 50%). A deposit of 20–30% to cover material costs is standard. Asking for 50–80% before starting work is a red flag: it removes the contractor's financial incentive to complete the job.
• Pressure to decide same day. Legitimate roofing contractors are busy; they do not need high-pressure tactics. A contractor who says the price is only valid today is using a sales technique, not a genuine business constraint.

How Trade2Base Helps Roofing Contractors Track Marketing Performance

Roofing businesses typically have two very different customer types: emergency call-outs, where someone has a leak and needs a roofer today, and planned re-roofs, where a homeowner has been thinking about it for months and gets three quotes. The marketing channels that generate these two job types are often completely different. Emergency call-outs often come from Google search and Checkatrade; planned re-roofs frequently come from referrals, van signage, or door-drop leaflets in an area where you've recently completed a visible job.

If you are spending money on Google Ads, Checkatrade, and leaflets without knowing which channel is producing which job type — and which converts to actual revenue — you are flying blind. Trade2Base tracks every enquiry through to a completed job, showing you the source of each lead, whether it converted, and what it was worth. That means you can see, for example, that your Checkatrade spend generates emergency call-outs with an average job value of £250, while your referral network produces re-roof enquiries worth £7,000 on average — and allocate your budget accordingly.

For roofing contractors looking to scale, understanding the economics of each marketing channel is not a nice-to-have — it is the difference between growing profitably and growing yourself into cash flow problems.
