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upgrading your conservatory roof, from improved energy efficiency and lower heating bills, to improving the look of an outdated design and getting rid of time-consuming maintenance.

Let's take a closer look at the different types of conservatory roof materials to help you find the best solution for your home and budget:

Replacement Polycarbonate Conservatory Roof Cost

How Much? Between £2,700 and £4,000 for a medium-sized roof.

Best For? Homeowners on a budget, who use their conservatory as an occasional space.

Pros

• ✔ Lightweight and easy to install.
• ✔ Affordable, good for those on a budget.

Cons

• ✖ Less visual appeal than other conservatory roof materials.
• ✖ Poor insulation (very hot in the summer, very cold in the winter).

Glass Conservatory Roof Cost

How Much? Between £3,200 and £4,800 for average-sized conservatories.

Best For? Maximising natural light in your conservatory.

Pros

• ✔ Modern aesthetic with lots of natural light.
• ✔ Better insulated than polycarbonate.

Cons

• ✖ Higher price point.
• ✖ Requires regular cleaning.

Solid Conservatory Roof Cost

How Much? Between £5,000 and £6,800 for an average-sized tiled conservatory roof.

Best For? People who want to turn their conservatory into a functional year-round room.

Pros

• ✔ Best for all-year use with excellent insulation.
• ✔ Feels most like a "real" room.

Cons

• ✖ Most expensive roof material.
• ✖ Can reduce the amount of natural light in the conservatory.

Cost of Alternative Conservatory Roof Options

The above materials are some of the most popular options for replacement conservatory roofs, but there are some less common options you might also want to consider:

• Aluminium Conservatory Roof Costs — Insulated panels with an aluminium facing can be a great way to improve energy efficiency and the appearance of your conservatory roof. As a specialist insulated system they tend to be at the higher end of the price range, and a new roof for an average-sized conservatory should be around £6,000 to £12,000.
• Insulated Solid Panel Conservatory Roof Costs — Another good option if you want to improve insulation, these solid panels replace traditional tiles or glazing and help to keep your conservatory cool in the summer and warm in the winter. For an average-sized conservatory roof they should cost between £5,000 and £12,000.
• Hybrid Panel Conservatory Roof Costs — Similar to the solid insulated panel option above, this combines these panels with glass panels across the roof, for the combined benefit of more insulation and maintaining natural light levels. Costs for an average-sized conservatory should be £4,000 to £10,000.

How Much Does Labour for a Replacement Conservatory Roof Cost?

When you're getting quotes from tradespeople, they'll typically bundle labour and materials together into a single set price. Labour usually accounts for 30% to 40% of the total project cost, with a 2-person team charging between £300 and £500 per day. Expect rates towards the higher end in London, the South East, and major cities.

The table below shows how size affects the timescale and estimated labour cost for the job:

How long does conservatory roof replacement take for different materials?

• Polycarbonate — The quickest to install. Lightweight panels mean a small to medium job can often be completed in a single day.
• Glass — Standard timescale. Slightly more involved than polycarbonate due to the weight and care needed during fitting.
• Solid/Tiled — The longest to install. Allow an additional 1 to 2 days compared to polycarbonate or glass, particularly if structural work is needed during a conversion.

What Impacts the Cost of a New Conservatory Roof?

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, the cost of your conservatory roof depends on other things, too.

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

Homeowners may decide to convert their roof to overcome specific problems, or improve how they can use their conservatory.

Issues like poor energy efficiency or too much sunlight may be improved by converting from polycarbonate/glass to an insulated panel system, and improving natural light while maintaining good energy efficiency can be achieved by converting to a hybrid panel system.

The costs of your conservatory roof conversion will vary, depending on the type of roof you currently have, and the roof system you want to convert to, as well as any additional work that will be required for the conversion.

For example, changing from polycarbonate or glass to a solid roof will cost more than a like-for-like replacement.

Here's why:

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

For an average 4m x 4m (16m²) sized space, conservatory roof conversion costs would be £1,500 to £3,000 higher than a like-for-like replacement.

If your plan to change to a solid roof is because you want to convert your conservatory into a proper room, it's worth mentioning that you might need to do more than just convert the roof.

Converting a conservatory into an extension costs more because there will probably be work required on the walls, doors, insulation, electrics, and possibly plumbing, all of which will add to your costs. You'll also need to make sure this work gets Building Control approval, and you may even need planning permission.

Glazing Specification

For a new glass conservatory roof, the grade of glass you choose can noticeably affect the final cost. Standard glass is the baseline, but several upgrades are worth knowing about:

• Self-Cleaning Glass — Has a special coating that breaks down organic dirt using daylight. Rain falling on the glass then spreads in a thin film, washing off the loosened dirt and drying streak-free. It typically costs 20 to 30% more than standard glass, but reduces ongoing maintenance.
• Solar Control Glass — In summer, this glass reduces solar heat and glare. If you also want to retain heat in winter, look for a low-emissivity coating as well. Expect a moderate premium over standard glass, but lower energy bills in the long run.
• Double or Triple Glazing — Improves insulation significantly. Triple glazing is the most thermally efficient option but comes at a higher cost.

If you're investing in a glass roof to maximise natural light, it's worth considering whether a glazing upgrade makes sense for your usage and budget.

Location

Where you live in the UK will affect the labour portion of your quote. Installers in London and the South East typically charge 20 to 30% above the national average, while rates tend to be lower in the North of England, Wales, and Scotland.

Material costs are broadly similar across the country, so the regional difference is mostly felt in the day rate you're quoted for labour.

What's Included (and Not Included) in the Cost of a Replacement Conservatory Roof?

The cost of replacing a polycarbonate roof is between £2,700 and £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).

And these items are not usually included in a conservatory roof replacement quote:

• Any required structural work.
• Fees for any professional services required (surveyors, engineers, etc.).
• Replacement fascias, soffits, guttering.
• Repairs to other areas like the frame.

Additional Costs of Replacing a Conservatory Roof

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

Conservatory Roof Blinds

Once you've replaced your roof, if your conservatory suffers from too much sunlight, new roof blinds can be worth the additional cost. Adding them to a like-for-like replacement to solve your sunlight problem can be a cheaper alternative than converting the roof to an alternative system, like solid panels or a solid roof.

Insulation Upgrades

If you're replacing your conservatory roof, it's a good opportunity to upgrade the insulation at the same time. Better insulation improves temperature control year-round and can help reduce heating bills. This will add to the upfront cost but can offer good long-term value.

Waste Removal

Removing the old roof and disposing of waste is typically included in your quote, but always confirm this before hiring. If you need to arrange it yourself, budget between £120 and £300 for the cost of hiring a skip. Most conservatory roof jobs won't need more than a single 4 to 6-yard skip.

Scaffolding

Scaffolding isn't usually required for conservatory roof replacements, as most installers will use ladders or their own access tower at no extra cost. However, confirm this when getting quotes. If scaffolding is needed, the cost of hiring scaffolding for a conservatory roof will typically be between £400 and £800.

Structural Work

If the existing framework needs reinforcement, particularly when converting to a heavier solid roof, additional structural work may be required. This could involve a builder or structural engineer, costing approximately £450 per day.

Roof Leak Repairs

A new roof should resolve most leaks, but if the leak is coming from elsewhere (such as the frame or guttering), you may need separate roof leak repairs. These typically cost around £375, depending on the extent of the work.

Conservatory Windows

If your conservatory windows also need attention, it makes sense to address them at the same time. Replacing just the glass typically costs £55 to £145 per unit, while full uPVC frame replacement conservatory windows cost around £200 to £550 per unit.

Electrical Work

After a new roof is fitted, you may want to update or install new lighting or fittings inside the conservatory. A qualified electrician will typically charge £30 to £50 per hour for this work.

Internal Finishing

This is one of the most commonly overlooked costs for solid roof conversions. Once the roof structure is in place, the interior ceiling will need plastering and, in most cases, painting and decorating, neither of which is typically included in a roofing quote. Budget an additional £500 to £2,000 depending on the size of the space, and confirm upfront whether your installer will arrange these trades or whether you'll need to book them separately.

Guttering and Drainage

A roof replacement can expose existing guttering problems that weren't previously visible. If gutters are cracked, sagging, or poorly aligned, it's sensible to deal with them at the same time rather than returning later. Replacing a run of guttering typically costs £150 to £500 depending on the length and material.

Benefits of Replacing a Conservatory Roof

If your conservatory roof is getting to the end of its useful life, it might be time to start thinking about replacing it. If you're thinking about the cost, it's worth bearing in mind some of the benefits of a new conservatory roof that make it worth the investment.

• Potential Energy Savings — A new roof could improve the energy efficiency of your conservatory, which could mean saving on energy costs.
• Less Maintenance — If your old roof has developed problems that need regular maintenance and repairs, a new roof should reduce this, and the costs.
• Improved Usability — A more energy efficient roof with no issues or leaks will make your conservatory a more enjoyable place to spend time.
• Better Appearance — On top of all the benefits above, a new roof will help improve the appearance, and your enjoyment, of your conservatory.

Should You Repair or Replace Your Conservatory Roof?

Even with regular maintenance, no conservatory roof lasts forever, but do you need a new conservatory roof, or would repairing the existing roof be possible?

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

Signs You Might Just Need to Repair Your Conservatory Roof

If you start to have issues with your conservatory roof, you might be able to solve the problem by fitting replacement conservatory roof panels rather than replacing the roof.

Polycarbonate and glass roof panels cost between £25 and £120 per m² supply only, and a replacement polycarbonate conservatory roof panel may cost just £150 to £400 supplied and fitted, which is significantly cheaper than a whole new roof.

Here are some common signs that you might just need a conservatory roof repair:

• 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 that you should be able to replace if the issue is isolated and doesn't affect the whole roof.
• Cracked or Loose Panels — Again, any damage to the panels themselves, and even to the glazing bars and seals themselves, may just need repairing or replacing, as long as the rest of the frame is sound.
• Slipped Panels — This can seem like a serious issue, but if the frame is sound, they may just need reseating with new seals, or at worst just replacing the panel.
• Minor Leaks — Minor leaks may be a result of any of the problems above, and as long as it's not the frame or structure that's failed, the appropriate repair should fix the problem.

Signs You Might Need to Replace Your Conservatory Roof

A replacement polycarbonate conservatory roof can cost thousands, so if you are able to fix your roof with some new panels or minor repairs, that would mean quite a saving. However, if the frame or any other part of the roof is damaged significantly, it may mean a full conservatory roof replacement is the best option.

Here's what to look for to see if you're going to need to replace rather than repair:

• 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 — Persistent damp caused by issues with the roof, which you are unable to get rid of after multiple repair attempts, may make it more cost-effective to replace the roof to solve the problem.
• Multiple Failing Panels — While replacement conservatory roof panels can be relatively inexpensive to fit, if you have issues with multiple panels, it may be more cost-effective to replace the whole roof.
• Slipped Panels — Slipped panels that can't be repaired or reseated are a more serious issue that's harder to repair. It usually suggests that there's a problem in the roof's structural frame and a replacement might be the best option.

If your conservatory is significantly outdated or extensively damaged, it may also be worth considering a full rebuild. Read our conservatory extension guide to explore what's involved.

Building Regulations for Replacement Conservatory Roofs

Do you need Building Regulations approval to change the roof on your conservatory?

The short answer: If you're replacing your conservatory roof with a like-for-like translucent material (polycarbonate or glass), you typically won't need Building Regulations approval, providing you still meet all of the below exemption criteria (in England and Wales, while those in Scotland and Northern Ireland should check local regulations):

• The conservatory is at ground level and single storey.
• Its floor area is 30m² or less.
• It's separated from the main house by external quality walls, doors or windows.
• It has its own heating controls outside the home's main heating system.
• Any glazing and any fixed electrical work meet the building regulations.

However, if you're swapping an old polycarbonate or glass roof with a solid or tiled conservatory roof, you will need Building Regulations approval.

This is because this type of change may change the classification of the room from a conservatory to a home extension, and will have additional requirements for insulation and ventilation.

If building control application fees are needed, add around £200 to £400 to your budget.

Can I Put a Solid Roof on My Conservatory?

Will my conservatory support a tiled roof? This all depends on the construction of your current conservatory and its foundations. Replacing a polycarbonate panel roof with tiles will significantly increase the weight of the roof, and it may not be possible without some structural upgrades to the conservatory.

Polycarbonate panels typically weigh around 3 to 4kg/m², whereas a lightweight tiled roof system would be around 38kg/m², so you can see how upgrading your roof could also require a structural upgrade for your conservatory.

You might not need as much structural upgrading for conservatories with heavier double-glazed glass (20 to 30kg/m²) or insulated panel (around 31kg/m²) roofs, but you would need to get a professional to check to make sure.

A structural engineer can carry out a survey of your conservatory for around £300 to £600, checking the frame, ring beam, and foundations to determine if your roof upgrade is possible, and what structural improvements might be required to achieve it.

Planning Permission for Replacement Conservatory Roofs

Most conservatory roof replacements won't need planning permission if you adhere to the following:

• The new roof projects a maximum of 150mm beyond the line of the existing roof slope.
• The new roof is no higher than the existing roof.
• Side-facing windows are obscure-glazed, and at least 1.7m above floor level if they can open.

These rules apply in England. Those elsewhere in the UK should check local rules. If you're planning on significantly changing the appearance of the roof in height or pitch, or changing the overall structure of the conservatory, you may need to apply for planning permission before starting work. You will also need listed building consent if you live in a listed building, regardless of the roof type.

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 polycarbonate or glass roofs. If needed, make sure that you're clear whether your builder will manage this for you.
• Is waste removal included? Most roofers 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).
