How Much to Replace a Conservatory Roof in 2025?

A professionally installed conservatory will last for decades and will be relatively trouble-free. However, the roofs tend to be the weakest link! If you spot any signs of leaking or water damage in your conservatory, you need to replace the roof as soon as possible to prevent any further damage.

Leaking roofs are likely caused by damage that has been building gradually over the years due to slipping or warping panels, loose cappings, leaking vents or simply sealant problems around the panels.

Sometimes, a temporary repair can be made to solve the immediate problems, but the only long-term course of action is to either replace the roof or get a new conservatory!

But even if the roof is not leaking, if you have a cheap conservatory polycarbonate roof, this can lead to condensation problems over time. In turn, this can cause mould, which is harmful to the lungs — so this may be another reason to consider getting yourself a new conservatory roof.

Getting a new roof is obviously a lot cheaper than getting a whole new conservatory, but it is still far from cheap! There are a number of factors that can affect the price you pay, the two biggest ones being the size of your conservatory and the type of roof material you want.

Glass roofs are typically more expensive than polycarbonate roofs but are more energy efficient and let more light in.

For example, for a small lean-to conservatory, the price to have a replacement polycarbonate conservatory roof fitted is on average around £1,900 to £2,600, whereas a glass roof on the same sized conservatory would cost on average around £2,000 to £2,800.

How Long Does Conservatory Roof Replacement Take?

To complete the job of replacing the roof on your conservatory, it will usually take between 1 and 3 days. The length of time depends on how many people are working on the job, the type of roof that you’re having installed, and the size of your conservatory.

For instance, the roof replacement on a small lean-to conservatory can usually be completed within 1 day, whereas a replacement on a large Victorian conservatory can take up to 3 days — or sometimes even longer — to complete.

Conservatory Roof Replacement Material Costs

If you are looking to replace your conservatory roof yourself, or if you wish to buy the supplies and conservatory roof panels in advance before looking into hiring labour to carry out the job, you may be interested in the costs of materials alone.

The cost for a glass roof on a lean-to conservatory is usually around £2,000 to £3,500 depending on the size of your conservatory. You can expect to pay more for materials if your conservatory is on the larger side than you would for a small conservatory roof.

If you were looking to purchase a polycarbonate roof for a lean-to conservatory, this would cost around £1,900 to £3,200 depending on the size of the conservatory.

If your conservatory is a traditional conservatory such as a Victorian conservatory, you will pay around £3,000 to £8,500 for the materials of a glass roof and around £3,000 to £8,500 for a polycarbonate roof on this style of conservatory.

Again, these prices range from small conservatories to large ones and you can expect to pay closer to the higher price for larger conservatories and closer to the lower price for smaller conservatories.

What Impacts Conservatory Roof Replacement Costs?

There are a number of factors that can affect the cost of having your conservatory roof replaced. Below is a list of the main things that can affect your conservatory roof replacement cost.

Size of Conservatory

The size of your conservatory can greatly affect the cost that you will pay for your conservatory replacement. A small lean-to conservatory roof can cost as little as £2,000 to replace whereas a large Victorian conservatory roof replacement can cost £8,500+.

The larger your roof is, the more it is going to cost to replace as you will need more materials to cover the entire roof and the job will also take longer so you will end up paying more in labour also.

Material of Roof

The material of the roof can make a difference to the amount you can expect to pay for your conservatory roof replacement. As an example, for a small lean-to conservatory, the price to have a polycarbonate roof fitted is on average around £1,900 to £2,600, whereas a glass roof on the same sized conservatory would cost on average around £2,000 to £2,800.

Location of Property

The location of your property can also make a difference to the overall cots that you pay for your conservatory roof replacement. Those who live in London can expect to pay anywhere from £30 to £100 more per day for labour than those in the North area of the UK.

Can I Replace a Conservatory Roof Myself?

Although replacing a conservatory roof could be completed by a couple of DIY enthusiasts, it is highly recommended that you hire a professional company or labourer to complete the work for you.

If the work is not carried out correctly and effectively, the conservatory roof could be prone to damage or leaks.

A leaking conservatory roof could lead to much worse problems down the line and could result in some hefty costs.

Choosing a Replacement Conservatory Roof

The two main types of conservatory roof are glass roofs and polycarbonate roofs. Below is a little bit of information on each of these types of roof.

Glass Conservatory Roof Replacement Cost

A glass conservatory roof is perfect for letting a lot of light into the room. If you really want to brighten up your conservatory space, then a glass roof is definitely the way to go.

A glass conservatory roof is a little bit more expensive than a polycarbonate roof. You can expect to pay around £200 to £1,000 more for a glass conservatory roof depending on the size and style of your conservatory.

Pros:

• ✔ Let’s in a lot of light
• ✔ Strong
• ✔ Durable
• ✔ Easy to clean
• ✔ Great aesthetic

Cons:

• ✖ More expensive than other options
• ✖ Can make the room very hot in summer
• ✖ Can make the room very cold in winter

Polycarbonate Conservatory Roof Replacement Cost

A polycarbonate conservatory roof is a great budget-friendly option for those who want to replace their existing roof.

It is strong and durable and can save you around £200 to £1,000 in installation and materials cost when compared to a glass conservatory roof.

Pros:

• ✔ Budget-friendly option
• ✔ Strong
• ✔ Durable

Cons:

• ✖ Not as aesthetically pleasing as glass
• ✖ Can develop grime over years if not well maintained

Tiled Conservatory Roof Replacement Cost

Some people choose to completely remove their conservatory roof and replace it with a tiled roof. This is a more modern approach and removes the aesthetic of the conservatory.

Since a conservatory was originally designed as a room to grow plants, the tiled look takes away the tradition of a conservatory and makes it more like just an extension on the home.

Pros:

• ✔ Strong
• ✔ Durable
• ✔ Blends in with the rest of the house
• ✔ Doesn’t get too overheated or too cold during summer and winter months

Cons:

• ✖ Not traditional
• ✖ Doesn’t look like a conservatory
• ✖ Pricey

Benefits of Replacing a Conservatory Roof

There are a number of benefits to replacing your conservatory roof. Below is a list of the main benefits that a replacement conservatory roof may bring to you and your home.

Prevent Leaks and Damage

A major benefit of replacing your conservatory roof is that your new roof will be free from any leaks or damage. If you are replacing your roof for the purpose of fixing a leak, a major benefit is that your new roof will prevent those leaks from happening.

More Likely to Last

A brand-new roof will be more likely to last a long time than your older roof. Over time, your roof can develop damage from things such as the weather. Modern roofs are built to last and so having a new roof put on your conservatory will ensure that your conservatory lasts for a very long time without issues such as damage or leaks.

Aesthetically Pleasing

Anything that is brand new looks great and a new roof on your conservatory is no exception to this. There are many great styles of roofing available, and you can even get tinted or coloured roofs that will make your home look great. A new modern-looking roof can completely transform the look of your conservatory.

Building Regulations for Conservatory Roof Replacements

Most of the time, you will not need any building regulation approval to replace your conservatory roof. As long as there is ‘thermal separation’ between the conservatory and the rest of your home, you can replace your conservatory roof without any restrictions.

This means that you need a door separating the conservatory from the rest of the house. The majority of conservatories already have this in place, as a conservatory is known for getting quite hot in the summer months and cold in the winter months.

It is also important to ensure that your new conservatory roof is strong enough to withstand weather conditions and is strong enough to carry snow if the situation arises that there is a heavy snowfall. Most modern conservatory roof materials are fully built and ready for this and will come with the appropriate building regulation approval already.

The only time that building regulations may come into play is if you are replacing your conservatory roof with a solid roof, such as having a tiled roof put on rather than a glass or polycarbonate roof.

In this case, your conservatory may be seen as being an extension rather than a conservatory. The company that carries out the work on your new roof will be able to provide you with the appropriate guidance regarding your particular conservatory and whether any building regulations or rules may need to be approved for your specific roof replacement.

Planning Permission for Conservatory Roof Replacements

Planning permission is concerned with any changes to your home that may affect your neighbours or the wider environment. Since your conservatory is already there, and you’re simply replacing the already existing roof, you do not need to worry about planning permission to change your roof.

It doesn’t matter what the type of roof is that you are replacing or that you are having put on your conservatory, you don’t need to worry about planning permission to have your conservatory roof replaced.

Removing a Conservatory Roof Cost

If you are looking at replacing your conservatory roof, you may be interested in removing the original roof to save some time or costs. Most companies that offer conservatory roof replacements will remove and dispose of the old roof as part of the job. However, you may want to remove the roof yourself if you would prefer to do so.

This can be done as a DIY project, but great care should be taken as removing a roof can be dangerous. You need to be aware of objects that may drop as you’re removing the roof, so appropriate safety wear, including a hard hat and safety glasses, should be worn when carrying out this job.

There is likely to be a lot of waste generated when removing the roof. In this case, it is recommended that you hire a skip to dispose of the waste materials.

A skip hire will cost somewhere between £100 and £300 on average for this type of job and the size of the skip that you hire will depend on the size of your conservatory roof and the amount of waste that you anticipate the job is going to create.

Checklist: Hiring a Conservatory Roof Replacer
