Cost of roofing repairs in the UK
The type of roof you have can significantly affect your roof repair costs.
Not only are some roofs more complex than others (for instance, sporting multiple chimney stacks or dormer windows), but some kinds of roofs are more prone to needing repairs.
Here, we'll look at some common roof types and materials, along with their related roof repair costs.
Flat roof repair cost
Unfortunately, older flat roofs are more prone to leaks than pitched roofs. This is because the felt-and-gravel style roofs on many suburban extensions are completely flat, giving rainwater no natural place to escape to.
However, the quality of flat roof construction has improved enormously over the past couple of decades. Modern flat roofs are now built up with firings, giving a 2-3˚ slope to allow water to run off.
The repair cost of a bitumen flat roof is around £100 - £140 per m²
Slate roof repair cost
When it comes to the cost of repairing your slate roof, the price you pay will depend on the size and complexity of the job. But it will also depend on the exact type and colour of slate your roof is made of.
As a general guide, you can expect to spend roughly £150 - £220 per m² on slate roof repair costs
Polycarbonate roofing repair cost
Typically used for garages, sheds, greenhouses, and conservatories, polycarbonate roofing is known for its lightweight and extremely hard-wearing characteristics.
However, polycarbonate sheets aren’t scratch-resistant. So, some surface denting or scratching may occur if the roof isn't properly maintained.
The average cost of polycarbonate roofing repair is around £120 - £170 per m²
Fibreglass roofing repair cost
Fibreglass is otherwise known as Glass Reinforced Polyester (GRP). It has become a popular roofing material thanks to its low cost, durability, and easy maintenance.
The average fibreglass roofing repair cost is around £90 - £130 per m²
Typical roof repair costs in the UK
Let's be honest, there are so many different types of roofing materials nowadays that it's hard to count them all! Here are the average roof repair costs for some other popular roof types:
Tiled conservatory roof repair: £90 - £120 per m² (concrete); £110 - £160 per m² (clay)
Liquid plastic roofing repair: £130 - £180 per m²
Single ply membrane roof repair: £120 - £170 per m²
Dry ridge repair: £50 - £70 per metre
Pitched roofing repair: £90 - £120 per m² (concrete); £150 - £220 per m² (natural Spanish slate 510mm x 225mm)
Glass roof repair: £85 - £145 per m² (6mm plain glass); £190 - £316 per m² (6.4mm laminated glass)
Roof lights repair: Starting at around £1,000 for a Velux rooflight replacement
Chimney cowlings repair: £85 - £145 per m²
Balcony roofing repair: £100 - £140 per m²
Ridge tile repair: £50 - £70 per metre

Calculating the cost to repair a roof
Two common roof issues are leaks and sagging. In this section, you'll find average project costs for roof leak repair and sagging roof repair.
Leaking roof repair costs
Leaking roof repair costs will depend largely on the severity of the leak and the issue that's causing it. Several common issues that can lead to a leaky roof include:
A hole in the felt or membrane, or simply degradation over time
A cracked tile
Poorly secured or damage to lead flashing
Failure in the rainwater management system
Wear and tear to fascias and soffits
Felt roofing repair cost
If your roof felt is damaged, repairing it is a fairly straightforward job, especially if the only roofing material is felt.
However, if you have tiles on top of the roof felt, then things can be a bit trickier. Getting access to repair the felt will require removing the tiles and then replacing them once the felt has been successfully repaired.
The average cost of felt roofing repair in the UK is around £265 per m²
Tile replacement cost
A missing or loose tile is a common issue that causes a leaking roof.
If you have missing or loose tiles, water can penetrate your roof. This should be fixed immediately to prevent further damage.
Costs for clay tile replacement start at £110 - £160 per m²
Cost to repair a roof valley
The roof valley is where two sloping roofs meet. Not only does it join up the roof, but it's built to channel rainwater down towards the gutter.
As you would expect, your roof valley deals with a huge amount of water and is prone to leaking over time. It will take around half a day to repair one roof valley, or a full day to repair two.
The costs for GRP roof valley repair will be on average £30 - £40 per metre
Flashing repair cost
Lead flashing helps to protect the edge of your roof where the tiles meet the brickwork.
As such, an issue with your lead flashing will have similar results to an issue with broken or missing roof tiles. It will allow rain into your home, which can quickly damage your interior.
If you have an issue with your lead flashing, you can expect your leaking roof repair cost to be fairly similar to the cost of replacing faulty tiles.
Repairing a metre of flashing will usually cost around £50 - £70 per metre
Leadworks repair cost
As well as being used for lead flashing, leadwork can cover and protect gutters, joints, and other parts of your roof.
When it's working properly, it provides waterproof protection and allows water to run off down the guttering channels. However, even though lead is a durable, long-lasting material, from time to time it will need repairing.
The cost of leadwork repair work will depend on several factors, including the size and type of your roof, the amount of leadwork that needs repairing, the ease of access, and whether scaffolding is needed.
The average cost of leadwork repair is in the region of £50 - £70 per metre

Sagging roof repair costs
A sagging roof is never a good sight to see. If your roof looks curved or wavy instead of straight, that's often a sign of a sagging issue.
Sagging roof repair costs vary. Ultimately, the treatment and cost will depend on the cause of the issue.
If the issue is the weight of the roof material on the timber frame, then additional joists may be required.
Depending on how many you need, this can cost around £25 per lm for 150 x 50mm rafter repairs
If your roof's sag problem is due to the internal structure becoming waterlogged, it will need to be repaired with binders or purlins with struts.
This can set you back around £30 - £40 per lm
Factors affecting the cost of roof repair
As we've touched upon, your roof repair cost will vary based on many factors, including:
The issue with your roof
The extent of the damage
Whether scaffolding is required
The style of your roof
What it's made of
When should I replace my roof altogether?
It's also worth mentioning that if you have a severe underlying issue with your roof, patch repairs will not be good enough.
The relatively high costs of continually repairing problems may mean that comprehensive re-roofing is required.
Re-roofing can take one of two forms:
If the existing rafters are found to be dry, stable, not rotting, and structurally sound, then the felt, battens, and tiles can be replaced
Otherwise, a much more invasive full rebuild of the roof structure will be required
In most cases, a full rebuild won't be needed. It's usually only an issue for properties that are many decades old. In fact, in properties that need a full rebuild, it's often evident just by looking at the bows and curves in the shape of the ridge or pitch!
Read our roof replacement cost guide for a more in-depth look at replacing the whole roof and what you can expect to pay for it.
Concerned your roof may need replacing?
A good place to start is to contact at least three checked roofing contractors in your area. They'll inspect the condition of your roof and give tips on whether a repair or a replacement may be needed.

Hidden costs to watch out for
Saving up for your roof repair? Don't forget to budget for the extras you might need.
On top of the cost to repair your roof, here are some other figures to account for:
Scaffolding: If you need it, there's likely to be an additional cost for scaffolding. The cost for a single scaffold up to 10m high is around £625 per week
Roof window repairs: If you need to repair or replace your roof window system (such as a Velux window), you could pay £800 - £1,100, if not more
Waste disposal: You may also need to pay for a skip. Skip hire prices for a 2-3 yard skip are usually between £60 - £150, while a builder 6-8 yard skip will be £230 - £295

Roofing repair cost: FAQs
What are some of the most common causes of roof damage?
Here are a few of the most common (and repairable) roof issues:
Leaks: Often due to cracked tiles, degraded membranes, or slipped flashing
Water stains or ceiling bubbles: A tell-tale sign of moisture getting through
Blocked or broken gutters: Can lead to overflow and roof edge damage
Rotting fascias/soffits: Especially common with older timber installations
General wear and tear: Ageing materials or storm damage can require patch repairs or replacements
In an ideal world, it's a good idea to regularly schedule roof inspections to spot small issues before they cause any damage to your home.
Terminology for parts of a roof in the UK
Confused by all the roof jargon? Our handy glossary of roofing terms will help you get on the same page!
Ridge: The highest point where two roof slopes meet, capped with either curved or angled ridge tiles
Valley: The V-shaped trough where two slopes meet (often prone to leaks)
Pitch: The angle or steepness of your roof, typically between 30-45˚ (or around 3˚ for a modern ‘flat’ roof). The taller the roof, the bigger the pitch. It affects drainage and structural load
Flashing: Usually lead, these protective strips seal the roof where it meets walls or chimneys
Fascias (bargeboard): The part where your roof meets the walls. They are decorative but also practical, carrying the guttering
Soffits: They bridge the gap between the top of the wall and the underside of the roof helping to ventilate the loft space
Eaves: The underhanging element where the roof meets the walls
Gable: The solid bit of wall that's on the same level as the pitched roof is called the gable, or gable end
Verges: The edge of a sloping roof as it meets a gable end
Will I need planning permission for a roof repair?
As long as there isn't any evidence of protected species, you can normally repair or replace your roof without planning permission, as it falls under your permitted development rights. That said, any alteration projects must be no more than 150mm from the original plane.
Building regulations approval will not be necessary if you are repairing or replacing less than 25% of your existing roof. If, however, your project is more significant, you will require building control approval.
Is a leaking roof covered by insurance in the UK?
It depends. Home buildings insurance usually covers roof leaks if they’re caused by sudden and unforeseen events, such as storm damage, fallen trees, etc.
However, if your leaking roof is caused by wear and tear, poor maintenance, or general age deterioration, it’s unlikely to be covered by your insurance.
Review your home insurance policy documents and contact your provider to be sure.
Why are roof repairs so expensive?
Several factors come into play to fix a roof. Firstly, the materials needed to withstand the UK climate aren’t cheap. Secondly, you’re paying for skilled labour to install them. Roofing contractors have to cover the cost of insurance, scaffolding, and waste disposal, to name just a few, which all add up.
How much does it cost to repair a sagging roof UK?
Sagging roof repair costs vary depending on the cause of the issue. If the issue is the weight of the roof material on the timber frame, then additional joists may be required.
Depending on how many you need, this can cost around £25 per lm for 150 x 50mm rafter repairs
If your roof's sag problem is due to the internal structure becoming waterlogged, it will need to be repaired with binders or purlins with struts.
This can set you back around £30 - £40 per lm
Who should repair or replace my roof?
Working at heights is dangerous, and repairing or replacing roofs is a skilled job. With that in mind, it's essential to employ an experienced roofing contractor so you know the work will last. Contact a reviewed tradesperson through Checkatrade.
