Roof Repointing & Retiling Cost UK 2026: Full Price Guide

Roof repointing and retiling are two of the most commonly needed — and most commonly overquoted — roof repairs in the UK. A roofer knocking on your door saying your pointing is "dangerous" and needs urgent £3,000 of work is a well-known cold-calling tactic. Equally, some homeowners put off genuine repairs for years and end up with far larger bills when water damage reaches the timbers beneath.

This guide gives you the numbers to know what fair looks like, the questions to ask any roofer who quotes, and the signs that tell you whether your roof actually needs work or whether someone is trying to sell you something you do not need.

Roof Repointing Costs

Repointing is the process of removing old, cracked, or crumbling mortar from the joints between roof tiles — most commonly along the ridge (the horizontal peak), hips (the sloping external corners), and valleys (the internal junctions) — and replacing it with fresh mortar. It does not involve removing the tiles themselves.

What is ridge tile repointing?

Ridge tiles are the rounded or angled tiles that run along the top of a pitched roof. They are bedded in mortar, and over time — typically 20–40 years — that mortar cracks, shrinks, and falls away. When it does, water gets underneath the ridge tiles, into the roof structure below. In severe cases ridge tiles can rock, shift, or fall, creating a safety hazard.

* Prices exclude scaffolding where required. Most ridge repointing on two-storey homes can be done from roof ladders or a scaffold tower (£200–£400 extra). Full scaffold erection adds £700–£2,000 and is typically only needed on larger detached homes or where tower access is impractical.

Dry-ridge vs mortar repointing: which is better?

Traditional mortar repointing is still the most common method, but dry-ridge systems — where ridge tiles are mechanically fixed with clips rather than mortar — are increasingly popular and arguably more durable. Mortar eventually cracks; dry-ridge systems don't. The trade-off is cost.

* If your roof is due a full retile within 10–15 years, traditional mortar repointing is cost-effective. If the roof is otherwise in good condition and likely to last 30+ years, investing in a dry-ridge system at repointing time avoids a repeat job.

Roof Retiling Costs

Retiling — replacing some or all of the tiles on a roof — is a bigger job than repointing. Costs vary enormously depending on how much of the roof is being replaced, the type of tiles, the pitch of the roof, and whether the felt underlay beneath the tiles also needs replacing.

Replacing individual broken tiles

If only a few tiles are broken, slipped, or missing, a roofer can replace them without disturbing the rest of the roof. This is almost always the most cost-effective solution where the surrounding tiles are in good condition.

* Matching existing tiles can be difficult on older roofs — your roofer should source matching tiles where possible. A visible mismatch does not affect performance but may matter if selling the property.

Partial retile — one slope or section

When one slope or section of the roof has extensive damage, age-related failure, or a frost-damaged tile batch, replacing that section while leaving the rest in place is often the right call. This is common on Victorian and Edwardian terraces where south-facing slopes deteriorate faster than north-facing ones.

* When retiling a section, the felt underlay on that section should always be replaced at the same time. Adding new tiles over old felt that is already brittle will result in a repeat job within a few years.

Full roof retile costs

A full retile involves stripping all tiles, inspecting and repairing the batten and timber structure beneath, replacing the felt underlay, and relaying new tiles across the entire roof. It is the most significant domestic roofing job most homeowners will face.

* All prices include stripping the old roof, replacing felt underlay and battens, and relaying new tiles. Scaffolding (£1,000–£2,500 for a full retile) is included in most contractor quotes but always confirm in writing. Skip hire for old tile waste adds £200–£400 depending on volume.

Roof Felt Replacement Costs

The felt underlay (sometimes called sarking felt or roofing felt) sits beneath the tiles on top of the roof rafters. It acts as a second line of defence against water, wind, and dust. Most UK roofs built before 2000 use a bitumen-based felt that degrades over 25–40 years. When it fails — becoming brittle, splitting, or sagging — it stops providing any secondary waterproofing.

Felt cannot be replaced without removing the tiles, which is why felt replacement is almost always done at the same time as a retile rather than as a standalone job.

* On a 70m² semi-detached roof, upgrading from standard felt to a breathable membrane adds approximately £200–£350 to the total job cost — almost always worth it given the tiles will not be lifted again for another 40–50 years. Ask your roofer to quote both options.

What Affects the Final Price?

Tile type and specification

Concrete interlocking tiles are the cheapest and fastest to lay — the most competitive quotes are almost always for concrete tiles. Clay plain tiles are traditional and look better on period properties but cost 30–50% more in materials and take longer to lay due to their smaller size. Natural slate (Welsh or Spanish) is the premium option — beautiful, durable (100+ years), but priced accordingly. Reclaimed slate can be cheaper than new but requires careful sourcing and matching.

Roof complexity

A simple gable-end roof (two rectangular slopes meeting at a ridge) is the cheapest to retile. Every additional feature — hips, valleys, dormers, skylights, chimney stacks, parapet walls — adds complexity, time, and cost. A roof with three dormers and a chimney can cost 50–80% more than a roof of the same area with a simple pitch.

Timber condition

Once the tiles are stripped, the roofer can inspect the rafters and battens. If timbers are rotten, undersized, or have been damaged by persistent leaks, they need repairing or replacing before the new tiles go on. This is legitimate additional work — budget £500–£2,000 for timber repairs on an older property, though most roofs need minor work only (a few replacement battens).

Access and scaffolding

Full scaffolding is non-negotiable for a full retile — it would be dangerous (and likely uninsurable) to do this work from roof ladders only. For partial retiles and repointing, a scaffold tower or roof ladder system may suffice depending on roof height and pitch. Always ask what the quoted access method is and ensure it is safe and insured.

Signs Your Roof Actually Needs Repointing or Retiling

Many homeowners are approached by roofers claiming urgent work is needed. Here is what genuine failure looks like — and what you should be able to verify yourself before spending anything.

How to Get Fair Quotes

For any job over £500, get at least three written quotes from separate contractors. For a full retile, you should have three quotes before agreeing to anything — the spread on a full retile job is often £2,000–£4,000 between the cheapest and most expensive legitimate quote, and getting all three costs you nothing but time.

Questions to ask every roofer who quotes

• What tile specification are you quoting? (Brand, type, and warranty)
• What felt specification are you using? (Standard bitumen or breathable membrane?)
• Does the quote include scaffolding? (If not, ask for a separate scaffold cost)
• Does the quote include skip hire and waste removal?
• What is the batten specification? (BS5534-compliant battens are the standard)
• Will you inspect and report on timber condition once stripped?
• What workmanship guarantee do you offer and is it in writing?
• Are you NFRC registered or do you carry public liability insurance? (Ask to see the certificate)

What a fair payment structure looks like

For repointing and small tile repairs: payment on completion is normal, with no upfront deposit expected. For a full retile: a deposit of 10–20% on signing, a stage payment when scaffolding is up and stripping begins, and the balance on satisfactory completion is a reasonable structure. Never pay more than 50% before work starts on a large job.

Repointing Before Selling Your Home

Failed ridge pointing is the single most commonly flagged roof defect in RICS Level 2 and Level 3 homebuyer surveys. When a buyer's surveyor notes it, they will almost always recommend a roofer's report — which delays the sale and gives the buyer an opportunity to renegotiate on price, typically by more than the actual repointing cost.

A £500 repointing job done before listing can remove a £1,500–£3,000 buyer renegotiation. Get a roofer to inspect and quote as part of your pre-sale preparation — it is one of the highest-return pre-sale maintenance jobs available.
