Looking To Get Your Roof Repaired? How Much Will It Cost?

During the winter months, when Britain is lashed with rain and high winds, the chances of a household needing to repair the roof are far higher – but how much do roofing repairs cost?. Replacing a whole roof is a costly business, but most repairs aren’t quite so expensive, and some may even be covered by your home insurance policy.

Common roof problems

There are several common roof problems that can occur in the UK. These include:

  1. Leaks: One of the most common roof problems in the UK is leaks. Leaks can be caused by a variety of issues, such as damaged shingles, cracked flashing, or damaged seals around vents and chimneys.

  2. Blocked gutters: Another common issue is blocked gutters. When gutters become clogged with debris such as leaves and twigs, water can back up and cause damage to the roof and the structure of the building.

  3. Blown-off or damaged tiles: High winds and severe weather conditions can cause tiles to become dislodged or damaged, which can lead to leaks and other issues.

  4. Condensation: Poor ventilation in the attic can cause condensation to form, which can lead to dampness and mould growth. This can eventually cause damage to the roof structure.

  5. Aging roofs: Over time, roofs can simply wear out due to exposure to the elements. This can lead to cracks, leaks, and other issues.

It is important to address any of these common roof problems promptly to prevent further damage to the roof and the building. Regular roof maintenance and inspections can help to identify and address any potential issues before they become more serious.

Cost of Replacing or Repairing Broken Tiles

One of the most common repairs required at any time of year on a roof is having missing or broken tiles replaced. This is often the sort of simple repair which is covered on a home insurance policy if you have taken out home emergency cover or something similar. The average cost for getting someone out to replace or repair tiles in your roof is £354 per square metre of tiles, including all labour and material costs. If you live in a bungalow or another style of house with an easy to access roof it is worth considering whether you can replace tiles yourself, as roofing tiles can cost as little as £2 each.

Costs To Repair Leaking Roof

Of course it depends why your roof is leaking, but on average the bill for repairing a leaking roof comes in at £400. Diagnosing the problem which is causing the roof to leak is often tricky as where the water appears in your house is often not directly underneath the leaky spot. Often the leak happens between the lead flashing around the edges of the roof, or because tiles have slipped or cracked. Unless the cause of the leak is glaringly obvious, it is best to get the professionals in to find the problem area for you.

Sagging roof repair costs

The cost of repairing a sagging roof in the UK can vary depending on the extent of the damage and the size of the roof.

As a rough estimate, the cost of repairing a sagging roof in the UK can range from £500 to £2000 or more. However, this is only an approximate figure, and the actual cost may be higher or lower depending on the specific circumstances of the repair.

The cost of repairing a sagging roof will depend on the cause of the sagging. If the sagging is due to structural damage, such as a weakened roof truss or joist, the repair costs may be higher. Additionally, the cost of repairing a sagging roof may be more expensive if there is significant water damage or other issues that require more extensive repairs.

It is important to address a sagging roof promptly, as failure to do so can lead to more serious damage and increased repair costs in the long run. It is recommended to get quotes from several reputable roofing companies to compare prices and ensure that you are getting a fair price for the repair.

Cost to repair a lead valley

As a rough estimate, the cost of repairing a roof valley in the UK can range from £150 to £500. However, this is only an approximate figure, and the actual cost may be higher or lower depending on the specific circumstances of the repair.

Lead flashing repair costs

As a rough estimate, the cost of repairing flashing on a roof in the UK can range from £150 to £500. However, this is only an approximate figure, and the actual cost may be higher or lower depending on the specific circumstances of the repair.

Flat roof repair costs

The cost of repairing a flat roof in the UK can vary widely depending on several factors such as the size of the roof, the extent of the damage, and the type of material used for the repair.

As a rough estimate, the cost of repairing a flat roof in the UK can range from £300 to £1000 or more. However, this is only an approximate figure, and the actual cost may be higher or lower depending on the specific circumstances of the repair.

If the damage is extensive or the flat roof is nearing the end of its lifespan, it may be more cost-effective to replace the roof rather than repair it. The cost of replacing a flat roof in the UK can range from £1000 to £4000 or more, depending on the size and complexity of the roof and the type of material used.

It is recommended to get quotes from several reputable roofing companies to compare prices and ensure that you are getting a fair price for the repair or replacement of your flat roof.

Roof joist repair costs

As a rough estimate, the cost of repairing roof joists in the UK can range from £200 to £800 or more. However, this is only an approximate figure, and the actual cost may be higher or lower depending on the specific circumstances of the repair.

If the damage to the roof joists is extensive or requires a significant amount of work, such as replacing large sections of the joists, the repair costs may be higher. Additionally, if there are other issues with the roof, such as leaks or damage to the roof tiles, the overall repair costs may be higher.

Cost of Rebuilding Chimneys

Many houses still have chimneys on them even if they no longer have a coal fire, and a cracking, crumbling chimney can cause serious damage to the roof if left to decay. Rebuilding a chimney is not cheap though, with the average cost coming in at around £2,500. Take care of the masonry work on your chimney by having it pointed and repaired regularly so that it does not get to the stage of needing a complete rebuild.

Costs of Retiling a Roof

If your roof has so many damaged tiles that the only option seems to be a complete retiling job, then the bill is likely to be around £3,500. This price only includes removing and replacing the original tiles; if the rafters and frame of the roof are unsound and need to be replaced the cost could be far more. Retiling work is generally undertaken in the warmer months when there are more hours of daylight and it is less likely to rain.

Guttering Costs

Experts advise us all to have our guttering and downpipes cleaned out on an annual basis, and this work is likely to cost around £200 for the average home. If your gutters are easy to reach, then this is work which is fairly easy to carry out yourself. If your guttering is cracked or leaky, replacing it costs around £200 per section replaced, and a down pipe is slightly cheaper to replace at £150.

When should I think about replacing my roof altogether?

There are several signs that indicate it may be time to replace your roof in the UK. These include:

  1. Age: Most roofs in the UK have a lifespan of 20 to 25 years. If your roof is approaching or exceeding this age, it may be time to consider replacement.

  2. Damage: If your roof has significant damage, such as cracked or missing tiles, extensive leaks, or severe weather damage, it may be more cost-effective to replace the roof rather than make repeated repairs.

  3. Energy efficiency: If your roof is not providing adequate insulation, you may notice higher energy bills and reduced indoor comfort. Replacing the roof with a more energy-efficient material can help to improve insulation and reduce energy costs.

  4. Appearance: If your roof is faded, discoloured, or has lost its aesthetic appeal, replacing the roof can improve the appearance of your home and increase its value.

  5. Mould or mildew: If your roof is prone to mould or mildew growth, this can be a sign of poor ventilation or other issues. Replacing the roof can help to improve ventilation and prevent mould growth.

It is recommended to have your roof inspected regularly by a professional roofing company to identify any potential issues and determine whether replacement is necessary. Additionally, if you are planning to sell your home in the near future, a new roof can be a major selling point and increase the value of your property.

Will I need planning permission for a roof repair?

In most cases, you do not need planning permission for a roof repair in the UK, as long as the repair work does not involve a significant alteration to the roof or the overall structure of the building.

However, there are some situations where planning permission may be required for a roof repair. For example, if you are planning to change the shape or height of the roof, or if you are adding a new roof to an existing structure, planning permission may be necessary.

Additionally, if you live in a listed building or a conservation area, there may be additional restrictions or requirements for any repairs or alterations to the roof.

It is recommended to check with your local council or a qualified roofing contractor to determine whether planning permission is required for your specific roof repair project.
