Conservatory Roof Replacement Cost

How Much to Replace a Conservatory Roof?

In 2026, the average conservatory roof replacement costs between £3,200 and £6,000. Prices will mainly depend on the size of your conservatory and the material you want to use on your new conservatory roof.

This is considerably cheaper than a full replacement conservatory extension, which typically costs around £15,000 in the UK.

Let's start by narrowing roof replacement costs down based on the size of your conservatory:

From this point, the main factor that impacts conservatory roof replacement costs is the roof material.

Here's what you can expect new conservatory roof costs per square metre to be in 2026:

• Solid Conservatory Roof — Between £300 and £600 per m².
• Glass Conservatory Roof — Between £200 and £400 per m².
• Polycarbonate Conservatory Roof — Between £175 and £350 per m².

Conservatory Roof Replacement Prices

As we've seen, polycarbonate is usually the cheapest conservatory roof material initially, but each material comes with pros and cons that can impact their long-term value overall. Let's take a further look at some conservatory roof replacement cost examples below, and discover which one might best suit your home and your budget.

Choosing a conservatory roof material requires striking a balance between price, appearance, and performance. There are clear benefits to upgrading your conservatory roof, from boosting energy-efficiency and lowering heating bills, to improving the look of an out-dated design and getting rid of time-consuming maintenance.

With that in mind, let's take a closer look at the different types of conservatory roof materials to help you find the best solution for your budget:

Polycarbonate Conservatory Roof Replacement Cost

Polycarbonate is the traditional conservatory roof structure, typically costing £2,700 – £4,000 for a medium-sized roof. It's the more affordable option and is lightweight and relatively quick to install.

Although durable (they can last up to 20 years), some homeowners find this style of roof less visually appealing than others, and it doesn't offer the best temperature control.

Glass Conservatory Roof Replacement Cost

Glass roofs typically cost £3,200 – £4,800 for average-sized conservatories and are an excellent choice for maximising natural light in your space. They are long-lasting and sit in the middle of the price range, although upgraded options such as energy-efficient glass or self cleaning glass will usually cost more. Although they cost more initially, glass roofs can last 30+ years, making them a potentially better long-term investment than polycarbonate roofs.

Like polycarbonate, glass roofs offer little temperature control and can make your space somewhat uncomfortable on very bright days.

Solid Conservatory Roof Replacement Cost

Converting from a glass or polycarbonate conservatory roof to a tiled (or solid) roof is an increasingly popular upgrade in the UK. However, it comes with the biggest price tag, with the average 4m x4m tiled conservatory roof cost coming to around £5,000 – £6,800. The investment can pay off in the long term, as these are also the most durable roofs and can last up to 50 years.

Instead of glass panels or a polycarbonate roof, a solid tiled roof can provide a more energy-efficient and well-insulated room, while also reducing external noise. A tiled roof can transform your conservatory into a comfortable living area all year round by keeping the temperature better-regulated than other options.

Although they let in less natural light, many homeowners prefer this look as it can be adapted to blend in well with the rest of the house.

What's Included in the Cost of Conservatory Roof Replacements?

The cost of replacing polycarbonate conservatory roof is between £2,700 to £4,000 - but what's included in that price?

Here's what's commonly included in your quote when replacing a conservatory roof:

• Removal of the existing conservatory roof panels
• Supply of the new conservatory roof materials (e.g., polycarbonate, glass, solid system)
• Standard labour to fit the new roof, including fixing, trims, and seals
• Making good and basic finishing around the edge of the roof
• Waste removal (optional, best to clarify)

What's Not Included in the Cost of Conservatory Roof Replacements?

There are, however, some additional costs when replacing your conservatory roof that may impact the overall price. Here we review some of the things that are not included in a standard conservatory roof replacement:

• Extra structural work – Repairs to the existing framework or other structural work may require a builder or even a structural engineer to oversee the work, should extensive repairs be required (costing approximately £450 per day).
• Roof leak repairs – Although replacing a conservatory roof may resolve some issues, the actual leak could be coming from elsewhere. Repairs typically cost around £375, depending on the extent of the work needed.
• Conservatory Windows – If your conservatory also needs window work, replacing just the glass usually costs £55–£145 per unit, while a full uPVC frame replacement conservatory windows cost around £200–£550 per unit.
• Electrical Work – After the new roof is fitted, a qualified electrician may need to install lights or other fittings, typically costing £30–£50 per hour.
• Waste Removal – While most installers include this, if not, skip hire can be arranged separately, averaging around £220 for a small skip.

What Impacts Conservatory Roof Replacement Costs?

As we've already covered, the size of the conservatory and the roof material are the two main factors that drive replacement conservatory roof costs.

However, these aren't the only factors that can push your quote higher or lower.

Let's take a closer look below.

Type of Conservatory

The shape and style of your conservatory roof will impact what you should expect to pay for a conservatory roof replacement.

Material costs won't vary much between roof types (assuming they're the same size). However, roofs with more complex shapes and styles will take longer to replace, which increases labour costs.

Here's how quotes vary for a medium-sized conservatory that's 4m x 4m (16m²) with different roof styles.

Conservatory Roof Conversion Cost

Changing from a glass or polycarbonate conservatory roof to a solid conservatory roof will cost more than a like-for-like replacement.

Here's why:

• Extra Structural Work — Might be required if the existing frame isn't strong enough to hold the extra weight of a solid roof.
• Insulation & Plastering — Required to finish the inside of a solid conservatory roof conversion (making it feel more like an extension).
• Building Control — Required when converting to a solid conservatory roof.

For an average conservatory that's around 4m x 4m (16m²), conservatory roof conversion costs would be £1,500 to £3,000 higher than a like-for-like replacement. This means the total cost will be roughly 30% to 40% higher.

Adding Conservatory Roof Insulation

If you're replacing your conservatory roof, you may also decide to add or upgrade the insulation at the same time. This will increase the upfront cost, but it can improve temperature control and make the space more comfortable to use all year round.

If you want to compare insulation options in more detail, see our guide to conservatory insulation costs.

Waste Removal

Conservatory roof replacements and conversions generate a lot of waste.

Removing the old conservatory roof and disposing of any waste is typically handled by installers and included in quotes. However, this is important to confirm before hiring anyone for this job.

If you're handling this yourself, you'll have to budget between £120 and £300 for the cost of hiring a skip. Most homeowners won't need more than a single 4 to 6-yard skip, but you'll want to confirm this ahead of time with the installer.

Ease of Access & Scaffolding Hire

In most cases, scaffolding isn't required when installing a new conservatory roof. Installers will usually replace the roof using ladders or an access tower they own (at no extra cost).

However, you should confirm this ahead of time when getting quotes. If they assess that scaffolding is required for access, they'll either bundle it into the total price you're quoted or ask you to arrange it separately.

If you're paying for it yourself, the cost of hiring scaffolding for a conservatory roof replacement will typically be between £400 and £800.

Labour Costs for Replacing a Conservatory Roof

When you're getting quotes from tradespeople, they'll typically bundle labour and materials together into a single set price.

Let's break down how much of the total cost is labour:

• Labour accounts for 30% to 40% of what a conservatory roof replacement costs.
• The day rate for a 2-person team is between £300 and £500. Expect rates towards the higher end of this range in London, the South East, and major cities.
• Most installers work as a team of 2 for jobs like this, as it allows them to complete the job safely and efficiently.

For example: replacing a 3m x 3m (9m²) glass conservatory roof costs between £2,200 and £3,400. Labour would account for £660 to £1,360 of this total.

How Long Does Conservatory Roof Replacement Take?

In typical cases, UK homeowners should expect a conservatory roof replacement to be completed within 2 days. How long it takes will mainly depend on the size of your conservatory, but the material you want to use also has an effect.

The table below shows what to expect for different-sized conservatories (assuming a 2-person team).

Polycarbonate roofs are easier to install, so the installers will finish slightly earlier. On the other hand, solid roofs tend to take a bit longer to finish. This is especially the case if you're converting from a glass or polycarbonate roof, as additional structural work may be required.

Do I Need a New Conservatory Roof?

Even with regular maintenance, no conservatory roof lasts forever.

Glass and polycarbonate conservatory roofs typically start showing problems after 10 to 20 years. Solid conservatory roofs tend to last longer, but you'll likely start to spot issues after around 25 years.

Here are the most common signs that your conservatory roof may need replacing:

• Leaking — If you find water or damp patches inside the conservatory and previous roof leak repair attempts haven't been successful, it's likely that a replacement is needed.
• Damp — Damp patches, mould, or a 'musty' smell inside of a conservatory indicate there's poor ventilation or moisture is somehow getting in.
• Discoloured, Misted, or Cloudy Panels — These are signs of UV exposure damage, moisture trapped in the panel, or materials approaching the end of their lifespan.
• Cracks — If there's any visible damage to the surface of a conservatory roof, it may start to let water slowly seep in.
• Slipped Panels — This is a more serious issue that's harder to repair. It usually suggests that there's a problem in the roof's structural frame.

Checklist: Hiring a Roofer to Replace Your Conservatory Roof

Consider these key points before hiring a tradesperson to install a new conservatory roof:

• Do they specialise in conservatory roofs? You're ideally looking to hire someone who has 2+ years of experience installing glass, polycarbonate, and/or solid conservatory roofs.
• Do they handle building control approval? You'll usually need Building Regulations sign-off when installing a solid conservatory roof, but not for glass or polycarbonate roofs. If needed, make sure that you're clear whether your builder will manage this for you.
• Is waste removal included? Most people will handle this on behalf of the homeowner. However, you should confirm that the removal of the existing roof and all waste disposal is included in the total cost quoted.
• Are they insured? It's not a legal requirement, but you'll want to ensure that they have public liability insurance. This covers you in case something goes wrong during the job.
• Do they have positive reviews? Check their MyJobQuote profile to find all the feedback they've received from other homeowners.
• Do they have examples of similar work? Take a look at the photos they've uploaded to their MyJobQuote profile. This will give you an idea of what they're capable of.
• Do they offer any guarantee? Good installers won't have any issue standing behind their work and providing some type of warranty (independently or via a scheme).
