There are many factors to consider when working out a roof repair cost, such as the size of the damaged area and the materials involved.
However, most roof repairs cost anywhere from £100 to £1,000. If the repair is severe or structural damage needs to be repaired then expect to pay more.
Flat roofs are less expensive to repair due to the material that they’re made from.

How much does roof repair cost?
An approximate amount for a roof repair cost is £100 – 1,000 in the UK. Roof repair costs will depend on several factors, with the main two being the type of material that your roof is made from and the labour costs involved.
Slate is one of the most popular types of roofing material in the UK, costing around £60 per square metre (m²). Other materials such as lead and tiles cost £80m² and £50m² respectively.
The table below outlines roughly how much it costs to repair a roof depending on the material used per m². It also provides an estimate of how much it may cost to complete a roof repair job over a total of 20m² as an example.

How much does flat roof repair cost?
Flat roofs generally cost around £100 – 800 to repair. Most flat roofs are protected using torch-on bitumen felt as it’s an extremely cost-effective option and offers around 10-15 years of protection before needing to be replaced.
When roofers calculate a flat roof repair estimate, they’ll consider the size of the damage to work out how many square metres of your roof needs to be repaired and the labour it will involve.
You might need to include additional flat roof repair costs if additional damage has been caused to the guttering. This could add between £100 – 300 to your final bill.
What are the other potential costs of roof repair?
Other potential roof repair costs in the UK depend on the size of the issue. On all roof repair estimates, the cost of labour will always be factored in. A professional roofer will normally cost up to £250 per day, and their fee gets added to the final price of the repair.
The hourly rate of professional roofers will vary depending on where you are in the UK. Along with the cost of labour, you may need to pay for a skip to collect all the damaged materials. The cost to hire a skip varies greatly. However, an average-sized 6-yard skip will set you back around £250.
How much does roof tile replacement cost?
Roof tile repair cost depends completely on how many tiles need to be replaced and the amount of labour needed to complete the work.
However, as a rough guide, it costs around £1,000 to replace 20 m² of roof tiles. Another thing to consider is the accessibility of the roof which could add an extra cost. However, this won’t affect the roof tile replacement cost of most homeowners unless your roof is particularly difficult to access.
Occasionally, roof tiles can slip due to the likes of high winds, corrosion and the roofing structure that holds the tiles in place failing. The cost to repair slipped roof tiles can cost £100 upwards depending on any potential damage under the roof’s surface.
How much does roof leak repair cost?
There are several things to consider when working out how much it costs to repair a roof leak, namely the size of your roof and the damage that the leak has caused. However, it will normally cost around £500 to fix a roof leak.
Most roof leaks are caused because the surface of the roof has become worn, leading to cracks or holes appearing. Water seeps through the outer protection of the roof, making its way through the underlay, insulation and ultimately ceiling or walls.
The roof leak repair cost will likely depend on the damage caused to the roofing materials and flashing that protects the likes of the roof valleys and chimneys.

Roof repair FAQ
Will I need planning permission for a roof repair?
You likely won’t need planning permission for a roof repair because the roof isn’t changing in any substantial manner. By repairing the roof, you’re simply improving the condition or mending what’s already there.
The only time you may need planning permission would be if you were getting a new roof which is a different type to your old one. For example, if you were switching from a flat roof to a pitched roof, the increase in height may have a detrimental impact on your neighbours home.
The pitched roof could obscure the sun or obstruct their view. As a general rule, it’s always best to check with the local council before undertaking any substantial work on your home.
Who should repair or replace my roof?
Whether you’re repairing or replacing your roof, it’s a substantial undertaking. Research has shown that a new roof can increase the value of your home by £10,000 on average, offsetting the roof repair cost.
That’s why it’s extremely important to choose the right professional roofer to carry out the work. Luckily, My Local Toolbox has you covered. If you have no roofing experience, attempting to carry out the job yourself could lead to more problems than it solves.
