How Much Does a Replacement Conservatory Roof Cost?

Conservatory roofing deteriorates over time, from leaks and draughts to discolouring. But you may also just want to change the look of your extension by replacing the roof with new glass or a solid/tiled structure that’ll better retain heat.

There are many companies in the UK that can help to transform your conservatory, but how much will the work cost? We’ve researched the market to find different prices for different materials and conservatory types, with a rough guide in the below table.

In summary, your new conservatory roof cost will be between £2,355 and £5,570. A glass roof will be cheaper than a tiled roof, for example, because the job is less labour-intensive and a solid construction may require structural work.

Specialist glass, such as energy efficient and self-cleaning glass, is also available. Specialist glass will cost more than standard glass but is often worth the extra cost. For example, energy efficient glass will help reduce your heating bills and is therefore likely to give you return on investment within a few years.

If you're considering a glass conservatory roof, we recommend asking installers to also provide a quote for specialist glass so you can decide if it's a big difference.



How Much Will a Tiled Conservatory Roof Cost?

Solid tiled conservatory roof

Replacing your conservatory roof with a solid, tiled construction can make your seasonal garden room into an extension that can be enjoyed all year round. But it's important to note that by replacing a glass or polycarbonate roof with a tiled roof, you'll be changing the classification of your conservatory from a 'temporary' to 'permanent' extension. You should consult your local authority's building control department to check whether you need to apply - or reapply - for planning permission, of which there'll be a cost.

With that in mind, it’s harder to estimate how much a tiled conservatory roof will cost for your home. Plus, where you live and who you use can also have an impact on the price, along with the size of your conservatory, the state of the existing structure, and whether you decide to add any Velux or roof windows.

However, as a rough guide, you can expect your tiled roof to cost from around £4,000 for a smaller conservatory and up to £6,000 for a larger conservatory.



How Much Will a Polycarbonate Roof Cost?

Polycarbonate plastic roofs are typically cheaper than glass roofs. However, they are much less popular as they are less energy efficient and let less light in. Conservatories with a polycarbonate roof also experience big differences in temperature in summer and winter.

5 Tips to Get the Best Price on Your Replacement Conservatory Roof

Tip 1 - Compare at least 3 quotes. We recommend you receive at least 3 quotes to ensure you get the best price.

Tip 2 - Compare local and national installers. We recommend comparing at least 1 local installer and 1 national installer to compare the difference in their products and prices.

Tip 3 - Get quotes in writing and ensure it includes all costs, such as material.

Tip 4 - Don’t simply choose the cheapest price. You should consider the quality and the likely energy efficiency of the roof you have installed.

Tip 5 - Make access to your conservatory easy. An installation company will quote higher if access appears to be difficult to access your conservatory as it will take them longer to install the new roof.

Can I Get the Work Done on Finance?

Most conservative roofing companies offer finance schemes where you can spread the cost over a number of months or years.

We recommend asking any company quoting for your new conservatory roof whether they offer a finance scheme.

Some companies offer a discount if you opt to pay monthly via a finance scheme provided by one of their third party finance providers. They offer a discount because the third party finance provider will pay them commission for your finance contract.

Typical time frames that you can spread payments across are 12, 24 or 36 months. However, beware that if they do offer a finance option with interest, it could mean the work will end up paying hundreds or thousands more than it should.



Choosing the Right Conservatory Roof Installer

When choosing your conservatory roofing company, we recommend that you check they’re a member of The Conservatory Association. This is a division of the Glass and Glazing Federation (GGF) which promotes technical and health and safety standards, and protects homeowners when buying glass and glazing services.

You should also check if the company is Fensa (Fenestration Self-Assessment) registered. Fensa specialise in ensuring that your conservatory is energy efficient and it’s possible you’ll need a Fensa certificate in order to comply with certain building regulations.

The best companies to install your new roof can be both national and local, and you should always compare at least 3 during your research. You can use The Eco Experts to compare national installer prices against local installer prices – just complete the form at the top of this page.

If you encounter any issues during your roof replacement, you can contact the Conservatory Ombudsman (dgcos.org.uk) who will help you resolve them.
