Conservatory Roof Replacement Cost

How Much to Replace a Conservatory Roof?

In 2025, 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.

Let's start by narrowing this down based on the size of your conservatory:

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

Polycarbonate is the most affordable option, but glass remains the most common choice in the UK. Solid conservatory roofs are becoming more popular though, as they have better insulation that makes the space usable all year round.

Here's what you can expect new conservatory roof costs per square metre to be in 2025:

• 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

With all this in mind, let's take a look at some conservatory roof replacement cost examples below.

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. We cover this in more detail in the 'Building Regulations & Planning Permission' later in this guide.

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.

Labour Costs & Location

You should expect the labour cost to replace a conservatory roof to make up around 30% to 40% of the total price you're quoted.

A team of 2 people will charge between £300 and £500 per day, but where you live in the UK will impact the daily rates you're charged:

• In London and the South East, rates will be at the top of this range.
• In major cities like Birmingham and Manchester, rates will be towards the upper end of this range.
• In Wales, Scotland, and the North, rates will be at the lower end of this range.

On the other hand, material costs are quite consistent across the UK for this type of job.

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 seperately.

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: repalcing 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.

Choosing a Conservatory Roof Material

Tiled Conservatory Roof Cost

Converting from a glass or polycarbonate conservatory roof to a tiled (or solid) roof is an increasingly popular upgrade in the UK.

One strong reason for this is that a solid conservatory roof has much better insulation. A solid roof stabilises the temperature all through the year, so that it's not too hot in summer or too cold in winter.

However, tiled conservatory roof costs will be higher than a glass or polycarbonate roof. You should expect to be quoted between £5,000 and £6,800 for a solid roof on an average-sized conservatory (4m x 4m, or 16m²).

Pros:

• ✔ Strong and durable.
• ✔ Matches aesthetic of your house.
• ✔ Makes the temperature more stable.

Cons:

• ✖ More expensive than glass or polycarbonate.
• ✖ Loses traditional aesthetic.
• ✖ Lets through less nature light.

Glass Conservatory Roof Cost

Glass is the traditional choice for a conservatory roof and remains the most common to see in the UK. It's the go-to option when homeowners want to maximise how much natural light is being let into the space (and the room connected to it).

Glass conservatory roof replacement costs land between polycarbonate and solid roof prices. For an average-sized conservatory (4m x 4m, or 16m²), you should expect to pay between £3,200 and £4,800.

Pros:

• ✔ Lets in lots of natural light.
• ✔ Strong and long-lasting.
• ✔ Easy to maintain.

Cons:

• ✖ More expensive than polycarbonate.
• ✖ Poor temperature control.
• ✖ Can be uncomfortable in direct sunlight.

Polycarbonate Conservatory Roof Cost

Polycarbonate is the most budget-friendly option for a conservatory roof replacement. While it is not as visually appealing as a glass or tiled roof, it's a durable and lightweight material that comes in at a slightly lower price point.

You should expect polycarbonate conservatory roof replacement costs to be between £2,700 and £4,000 for an average-sized conservatory (4m x 4m, or 16m²).

Pros:

• ✔ More affordable option.
• ✔ Easier to install than alternatives.
• ✔ Durable.

Cons:

• ✖ Less visually appealing than glass or tiles.
• ✖ Poor temperature control.
• ✖ Requires more maintenance than alternatives.

Building Regulations & Planning Permission for Conservatory Roofs

Building Regulations

If you're only replacing a glass or polycarbonate conservatory roof with the same type of material (i.e., like-for-like), then Building Regulations approval will usually not be required.

However, you will need Building Regulations approval if you're upgrading to a solid conservatory roof from a glass or polycarbonate one. This is because solid roof systems are heavier and have better thermal performance, which triggers a structural review.

This means that the work must be signed off by your local authority or a private building control inspector. When the work is approved, you'll get a Building Regulations Compliance Certificate which is written confirmation that the work is compliant.

Many installers will handle all of this on behalf of the homeowner, but it's something you'll need to confirm when getting quotes. But even if they will handle this for you, be aware that it remains the homeowner's legal responsibility to ensure the work is compliant.

Planning Permission

In most cases, you won't need to get planning permission when replacing your conservatory roof. Even if you're converting to a solid conservatory roof, it's not something you'll need unless you're increasing the height or size of the roof.

If you're planning on installing a solid conservatory roof and removing the doors that separate it from the main house, the space will be considered an extension and subject to different rules.

But even in this case, you won't need to worry about planning permission as long as the conservatory space is within permitted development limits.

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, it's a clear sign that a repair or 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. Make sure that you're clear whether they'll 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 photos they've uploaded to their MyJobQuote profile. This will give you an idea of what they're capable of.
