Solid Conservatory Roof Replacement: What to Know

Conservatory Roof Replacement

If you own a conservatory, you may have noticed that the roof is not holding up as well as the rest of the structure. This is because the roof is exposed to the elements and can become damaged over time. If you are experiencing leaks, drafts or other issues with your conservatory roof, it may be time for a replacement.

Replacing a conservatory roof can be a cost-effective way to update your conservatory and make it more energy-efficient, whilst also adding value to your home and providing you with a more comfortable living space.

Key Points

  • Replacing a conservatory roof can be a cost-effective way to update your conservatory and make it more energy-efficient.
  • Solid roof conservatories are a popular choice for homeowners looking to replace their existing conservatory roof.

Why should you replace the roof on a conservatory?

As time goes by, the roof of your conservatory may start to show signs of wear and tear. This can lead to a range of issues, including leaks, drafts and reduced insulation. In some cases, it may be more cost-effective to replace the roof rather than trying to repair it. 

Types of conservatory roof materials

There are several types of materials that can be used for conservatory roofs. The most common types are polycarbonate and solid roofs. Polycarbonate roofs are lightweight and affordable, but they offer poor insulation and are prone to discolouration over time. Solid roofs, on the other hand, are more expensive but offer better insulation and durability. They can also be customised to match the style of your home.

If you are looking to upgrade the insulation of your conservatory, a solid roof is the way to go. This type of roof can help to reduce heat loss in the winter and keep your conservatory cool in the summer. It is also more durable than polycarbonate roofs and can withstand harsh weather conditions.

What Is a solid roof conservatory?

One conservatory roof option that has become increasingly popular in recent years is the solid roof conservatory – this type of conservatory features a solid roof rather than a traditional glass or polycarbonate roof.

Solid roof conservatories offer a number of benefits over their glass or polycarbonate counterparts. For one, they are much better at retaining heat, making them ideal for use all year round. They also offer better sound insulation, which can be particularly important if you live in a noisy area.

There are many different types of solid roof conservatory available, including those made from lightweight solid tiles, composite slates and more. Some even feature glazed panels or Velux windows to let in natural light.

What is involved in a solid roof replacement?

Conservatory roof replacement typically involves a fair bit of planning, including consideration of:

  • If the existing conservatory structure can withstand the weight of a solid roof
  • Whether a new roof frame is needed, such as a timber frame
  • Whether foundations are up to standard
  • What type of solid roof you want
  • Whether additions are needed, such as velux windows, skylights and ventilation

Building Regulations for conservatory roof replacements

Building regulations do apply to conservatory roof replacements – this means that the work must comply with standards to ensure that it is safe and meets energy efficiency requirements.

According to NCC, “if more than 25% of the roof area is replaced, then the building regulations will apply.” 

One way to ensure compliance is to use a solid roof system that has been approved by the Local Authority Building Control (LABC), a not-for-profit organisation that provides building control services to local authorities in England and Wales. 

When choosing a solid roof system, it is important to choose one that has been approved by the LABC. This will ensure that the system has been tested and meets the required standards for energy efficiency and safety.

In addition to complying with building regulations, it is also important to consider whether planning permission is required for the conservatory roof replacement. In most cases, planning permission is not required for a conservatory roof replacement, but it is always best to check with your local planning authority to be sure.

Pros and cons of replacing a conservatory roof with a solid roof

If you own a conservatory, you may have noticed that it can get very hot in the summer and very cold in the winter. This is because most conservatories have a lightweight plastic or glass roof that doesn’t provide much insulation. 

This is one of the main reasons why people replace their conservatory roofs and the most noticeable benefit.


Better Insulation: A solid roof will provide better insulation than a glass or plastic roof, making your conservatory more comfortable to use all year round. This is because solid roofs are made from materials that are better at retaining heat, such as tiles or slates.

Cost Effective: With better insulation comes lower heating costs, meaning that you can save more on your energy bills by retaining heat in colder months and using less energy-zapping cooling methods in warmer weather.

More Environmentally-Friendly: Using less heating and cooling methods uses less energy which, in simple terms, is better for the environment.

Reduced Noise: A solid roof will also reduce the amount of noise that enters your conservatory. This can be particularly beneficial if you live in a noisy area or if you use your conservatory as a home office or study.

More Privacy: A solid roof will provide more privacy than a glass or plastic roof. This can be particularly beneficial if your conservatory is overlooked by neighbouring properties.

Improved Aesthetics: A solid roof can improve the overall appearance of your conservatory, making it look more like an extension of your home rather than a separate structure.


Upfront Cost: Replacing a conservatory roof with a solid roof can be expensive, with costs ranging from £2,500 to £17,000 depending on the size of your conservatory and the materials used. However, the cost can be offset by the increased comfort and energy savings that a solid roof provides.

Planning Permission: In some cases, replacing a conservatory roof with a solid roof may require planning permission. This can be a lengthy and expensive process, so it is important to check with your local planning authority before proceeding.

Reduced Natural Light: A solid roof will reduce the amount of natural light that enters your conservatory. This could make the room feel darker and less airy, which may not be to everyone’s taste.

How much does a conservatory roof replacement cost?

When it comes to conservatory roof replacement, the cost can vary depending on several factors. These include:

  • The size of the conservatory
  • The type of material used
  • The complexity of the roof design 

According to our research, the average cost for a standard solid conservatory roof replacement is around £16,000. However, for larger conservatories, prices can start at around £30,000.

The cost of a conservatory roof replacement can also vary depending on the type of material used. For example, a tiled conservatory roof can cost around £5,500 for a 3 x 3 metre conservatory.

How long does it take to replace a conservatory roof?

The time it takes to replace a conservatory roof varies depending on the size of the conservatory, the complexity of the roof design and the type of material used.

On average, a conservatory roof replacement can take anywhere from a few days to a couple of weeks. However, a simple design can take less time to replace compared to a complex design.
