Roof Leak Repair Cost

How Much to Fix a Leaking Roof?

Roof leak fixes in the UK will set you back anywhere from £220 to £550, though some jobs creep higher than that.

What you'll actually pay depends on quite a few things. How bad is the leak? A couple of slipped tiles might only cost £150 to £300 to fix. But if you are dealing with serious flashing problems or the leak has caused structural damage, you could be looking at £800 to £1,000 or more.

The type of roof you've got makes a big difference, too. Standard pitched roofs with normal tiles are fairly straightforward to work on. Flat roofs can be trickier because water just sits there instead of running off properly. And if you've got slate? Well, that's specialist territory with specialist prices to match.

Getting to your roof affects the price as well. If it's easy to reach with a ladder, costs stay sensible. But if it's steep, really high, or tucked away behind extensions, you're looking at scaffolding and safety equipment - all of which costs extra.

Need someone out urgently? That'll cost you. Emergency callouts during storms or antisocial hours typically add £100 - £300 to the bill, sometimes more if it's a bank holiday.

Roof Leak Repair Prices

Here's a breakdown of how much different roof repairs cost:

These prices cover labour and basic materials. If you need fancy tiles or there's extensive damage, expect higher costs. Plus, any internal repairs from water damage come on top of the roof work.

It's worth checking your home insurance, as leaks caused by sudden damage, such as from storms, fallen trees, or other unexpected events, are often covered. While wear and tear, poor maintenance, or simply old age typically isn’t.

Labour Cost to Repair a Leaking Roof

Most roofers charge £35 to £45 per hour or £280 to £360 per day. Larger or more complex jobs often require 2 roofers working together, which can push daily labour costs to £560 to £720.

Where you live makes a difference. London and the South East typically cost 20 to 30% more than the North. In some rural areas, fewer available specialists can also push rates up despite lower general running costs.

The table below gives a guide to how long common repairs take and what you can expect to pay in labour costs alone.

Weather is the most common cause of delays. Roofers cannot safely work in rain, high winds, or icy conditions, so jobs planned for a single day can sometimes run into a second. Winter work also takes longer due to shorter daylight hours. Where timing is flexible, spring and summer are generally better seasons to book.

Supply Cost of Leaky Roof Repairs

For most roof repairs, materials make up around 20 to 30% of the total bill. Labour accounts for the rest. In most cases, your roofer will source and supply all materials as part of their quote — you won't need to buy anything separately.

Small repairs, such as replacing a few tiles or fixing flashing, typically use £50 to £150 in materials. Larger jobs, such as patching a flat roof or addressing chimney and valley problems, may require £150 to £400 worth of materials.

See our price table below for a breakdown of typical roofing material costs.

If you are sourcing materials yourself, the table above gives a guide to typical costs. That said, roofers often have trade accounts and can buy materials at lower prices than those available to the public, so it is usually more cost-effective to let them handle supply.

Additional Leaking Roof Repair Costs

• Emergency callouts — Usually £100 to £300 on top of normal prices.
• Scaffolding — Usually £300 to £800 for a house.
• Skips — £150 to £400 depending on size.
• Internal repairs — Replastering costs £200 to £500, redecorating adds another £150 to £400, and electrical work starts around £100 to £300.
• Gutter cleaning or minor repairs — £80 to £200.
• Roof inspection or leak detection — £80 to £200 if no repair is carried out on the day.
• Temporary weatherproofing — £100 to £300, depending on access and materials required.

Factors That Impact Leaking Roof Repair Costs

As well as the additional costs highlighted above, several other factors that can push up the cost to carry out roof repairs include:

• Type of Roof – The size and steepness of your roof both matter. Steep roofs are more dangerous and take longer to work on.
• Accessibility / Roof Height – High or awkward roofs take longer to work on, especially steep pitches or roofs with limited access.
• Roofing Material – What your roof is made of makes a huge difference. Concrete and clay tiles are fairly standard to work with, while slate requires specialist knowledge and more expensive materials. Flat roofs need completely different skills.
• Extent of Damage – How long the leak has been going on affects costs. Water-damaged timber or structural problems may require more than just a surface patch, potentially needing new roof beams or joists. The location of the leak also matters; edges are usually easier to reach, whereas valleys or areas around chimneys are more awkward and time-consuming.
• Timing of the Work – Emergency repairs are more expensive than planned work. If you can wait for normal hours and decent weather, you’ll save money. But if water is actively causing damage, paying extra for urgent roof repairs is usually worth it.
• Suspected Asbestos - Older roofs which may contain asbestos may need testing and special disposal. This can significantly delay roof repairs and increase quotes. Asbestos removal costs typically range between £500 to £1,500.
• Local Labour Availability – In some areas, specialist roofing tradespeople are harder to find, which can increase labour rates.

Types of Roof Leak Repairs

There are several different ways a roof can develop leaks, and the repair method depends on the type of damage and where it’s located.

Below, we’ve outlined the most common roof leak repairs and what each involves, and provided typical costs to help you budget.

Tiled Roof Repairs

Broken tiles are usually the easiest fix - take off the damaged ones, check what's underneath, put new ones back.

Leaking roof repair costs for tiled roofs are usually between £150 to £400.

Flat Roof Repairs

Flat roof repairs mean patching holes in felt or rubber. Modern materials like EPDM last much longer than old felt.

Expect to pay £200 to £600 for most flat roof work.

Flashing Roof Repairs

Flashing repairs are common around chimneys and where different roof sections meet. Lead can corrode, modern alternatives can split or come loose. Need someone who knows how to make it properly watertight.

This usually costs between £200 and £500.

Chimney Repairs

Chimney work often involves repointing the mortar and fixing the flashing. These spots get hammered because they handle lots of water.

Repairs usually cost between £300 and £800 (depending on how bad it is).

Ridge Tile Repairs

Ridge tiles along the top of your roof can come loose in high winds or when the mortar gives up.

This costs between £250 and £600 to fix, but it's essential to stop water getting in.

Valley Roof Repairs

Roof valleys are where the two slopes of a roof meet and form a channel to drain away all the rainwater. Over time, the materials can crack or erode and become blocked with debris, which can cause water to seep under the tiles. Valley roof repairs involve clearing the channel of any obstructions and repairing any damaged material to stop any leaks and make sure the channel drains properly.

This can cost between £400 and £800 to fix, but is essential for an area of the roof that handles a lot of rainwater.

Slate Roof Repairs

Slate roofs need specialist skills and materials that standard tiled roofs do not, as damaged tiles on a slate roof can't simply be swapped for concrete alternatives.

A roofer with experience in slate will assess the roof structure, replace damaged tiles with matching replacement tiles, and check the surrounding roof covering for any further roof repairs needed.

GRP Roof Repairs

Glass reinforced polyester is one of the most durable roofing materials available. A GRP patch repair is a common solution for localised roof damage where the whole roof does not need to be replaced. GRP repairs require specialist skills but are usually more cost-effective than a full roof replacement.

What are the Signs You Need a Major Roof Repair?

In some cases, patching or small roof repairs won’t solve the problem for long. A complete roof replacement is a far bigger job, with £5,250 being the average cost to replace a roof, so the right choice comes down to how much of the roof is affected.

Here are the main signs that a complete roof replacement or major upgrade may be the smarter option:

• Frequent leaks – If you’re calling out roofers every few months, ongoing repair bills can soon exceed the cost of a full roof replacement.
• Widespread damage – When broken tiles, cracked flashing, or perished felt cover large areas of the roof, roof repairs are rarely cost-effective.
• Aging materials – Most flat roofs last 20 to 30 years, while tile and slate can last far longer. If your roof is near the end of its lifespan, a flat roof replacement may be the most cost-effective option.
• Structural issues – Rotting timbers, sagging sections, or damaged joists go beyond surface roof repairs and typically require partial or full replacement.
• Energy efficiency – Older roofs often lack modern insulation or waterproofing. Upgrading during a roof replacement can reduce heat loss and future bills.
• Failed inspections – A professional roof inspection highlighting major weaknesses, unsafe structures, or extensive wear is a clear sign roof repairs won’t be enough.

If you notice several of these signs, it is worth getting at least 3 quotes from qualified roofers to compare repair costs with the cost of ongoing roof maintenance or a full replacement.

Hiring Contractors Checklist for Roof Leak Repair

Consider these key points before hiring a tradesperson to repair your leaking roof:

• Are they qualified? – Look for roofers with recognised credentials such as Competent Roofer certification or NFRC membership to ensure professional standards and good experience of repairing leaky roofs.
• Are they insured? – A contractor should hold public liability cover (at least £2 million). This covers you in case something goes wrong during the job.
• Is waste removal included? – Most contractors will handle this on behalf of the homeowner, but, you should confirm that the removal of the existing roof and all waste disposal is included in the total cost quoted.
• Do they have positive reviews? – Check their MyJobQuote profile to find all the feedback they've received from other homeowners.
• Can you check their past work? – Ask to see recent jobs or view completed projects if possible. Take a look at photos they've uploaded to their MyJobQuote profile. This will give you an idea of what they're capable of.
• What are the payment terms? – Agree on terms before work begins. Avoid paying large sums upfront. A typical arrangement is a 10–20% deposit, with the balance paid on completion.
• Do they offer any guarantee? – Good installers won't have any issue standing behind their work and providing some type of warranty (independently or via a scheme).

Aim to get at least 3 quotes from roof installers near you. This'll give you a clearer picture of the going rate and help you find someone who's a good fit for the job.
