We have been installing tiled conservatory roofs across Essex for over 15 years. In that time we have spoken to hundreds of homeowners who are frustrated with conservatories they can barely use, misled by quotes they don’t understand, and confused about which roof system is actually worth the money.
This guide is everything we wish someone had told those homeowners before they started. It covers how tiled conservatory roofs work, what they genuinely cost, which system we recommend and why, what planning permission and building regulations actually mean for your project, and the mistakes we have seen other installers make that you need to avoid.
If you are ready to get a quote now, head straight to our tiled conservatory roof installations in Essex. Otherwise, read on and we will give you everything you need to make the right decision.
In this guide:
What is a tiled conservatory roof?
A tiled conservatory roof is a lightweight, fully insulated roof system designed to replace an existing glass or polycarbonate conservatory roof. The key word there is lightweight. When we first started in this industry, converting a conservatory roof meant substantial structural work to support the weight of a traditional tiled roof. Modern systems changed all of that.
Today’s tiled roof systems use pre-engineered insulated structures that fit directly onto the vast majority of existing conservatory frames without any need to strengthen the foundations or structure underneath. The system replaces your old roof with a series of insulated panels, covered externally with lightweight tiles and finished internally with a plastered, painted ceiling.
There are two main types of system on the market. Aluminium-framed systems are precision-engineered off-site to your exact specifications, making for a fast installation with minimal disruption. Timber-framed systems use a natural material that acts as an insulator in its own right, eliminating the cold bridging risk associated with metal frames and achieving the highest thermal performance currently available.
The result of either approach looks and feels indistinguishable from a permanent room in your home. In fact, one of the things we hear most often after a job is done is that visitors do not realise it was ever a conservatory at all.
The Benefits of a Tiled Conservatory Roof
1. Year-round usability
This is the reason almost every customer comes to us. According to Eurocell’s Great British Conservatory Census, approximately one in five British households has a conservatory – around 3 million homes – and the single biggest complaint among owners is that their conservatory is too hot in summer and too cold in winter. The same survey found that 53% of conservatory owners cited this as their primary frustration. Most of those conservatories were built during the polycarbonate boom of the 1980s and 1990s, and most of them are now uncomfortable, inefficient and underused.
A tiled roof solves the problem permanently. The combination of a fully insulated structure, a U-value of 0.15 W/m²K as standard, and an internally plastered ceiling means the space holds heat in winter and stays cool in summer. The temperature extremes that make a glass or polycarbonate conservatory unbearable simply do not exist with a properly installed tiled roof.
2. Thermal Performance
U-value is the standard measure of heat loss through a material. The lower the figure, the better the insulation. Here is how the three main roof types compare:
- Tiled conservatory roof: as low as 0.12 W/m²K with a timber-framed system, or 0.15 W/m²K with an aluminium-framed system
- Glass conservatory roof: 1.2 to 3.0 W/m²K
- Polycarbonate conservatory roof: 1.6 W/m²K for standard 25mm polycarbonate
Either system is between eight and twenty times more thermally efficient than the alternatives. In practical terms that means lower heating bills, a more comfortable room, and no more abandoning the conservatory the moment the temperature drops. We will advise on which system is right for your project during the free onsite survey.
3. Noise Reduction
Rain on a polycarbonate roof is one of the most common complaints we hear from homeowners. It is genuinely one of the first things people mention when they call us – and it is backed up by the data: noise from rain was cited as a top complaint by 12% of conservatory owners in Eurocell’s survey. A tiled roof eliminates it entirely. The combination of external tiles, insulated panels and a plastered internal ceiling absorbs sound rather than amplifying it, giving you a genuinely quiet room even during heavy rainfall.
4. Aesthetics
A well-installed tiled conservatory roof looks like a natural, permanent part of your home. Externally the tiles blend with your existing roofline. Internally the vaulted plastered ceiling creates a sense of space and quality that no glass or polycarbonate roof can match. We have had customers tell us their estate agent increased the property valuation after seeing the finished result.
5. Durability
With a tile lifespan of 50 to 60 years and a system designed to withstand British weather, a tiled conservatory roof is a genuinely long-term investment. Compare that to polycarbonate, which typically starts to discolour, yellow and become brittle within 10 to 15 years, and the long-term value case is clear.
Tiled vs Glass vs Polycarbonate - Which is Right For You?
We always tell customers the same thing: we would rather give you an honest comparison than push you towards the most expensive option if it is not right for your situation. So here is a genuine assessment of all three.
| Tiled | Glass | Polycarbonate | |
|---|---|---|---|
| U-value | 0.12 to 0.15 W/m²K | 1.2 to 3.0 W/m²K | 1.6 W/m²K (25mm) |
| Lifespan | 50 to 60 years | 20 to 25 years | 10 to 20 years |
| Natural light from above | Low (unless roof windows added) | High | High |
| Noise reduction | Excellent | Poor | Very poor |
| Summer heat | Stays cool | Can overheat | Can overheat |
| Winter warmth | Excellent | Poor | Poor |
| Aesthetics | Extension-quality finish | Modern, light feel | Budget appearance |
| Typical cost | Highest upfront | Mid-range | Lowest upfront |
Choose a tiled roof if you want to use your conservatory all year round, you value a high-quality internal finish, or you are frustrated with heat, cold or noise from your current roof. This is the right choice for the vast majority of homeowners we speak to.
Choose a glass roof if natural light from above is your top priority and you are willing to manage temperature with heating and cooling. Modern glass roofs with solar control coatings perform significantly better than the older systems that were common in the 1990s.
Choose polycarbonate if budget is the overriding constraint and you are replacing a roof on a conservatory you use occasionally rather than daily. Just be aware it will need replacing again sooner than either of the alternatives.
Which Tiled Roof System is Best?
This is a question we get asked a lot, and we want to give you a genuinely useful answer rather than just a sales pitch.
There are several tiled conservatory roof systems on the market. The main ones are SupaLite, WARMERroof, Guardian, Equinox and Leka. Over 15 years we have installed and evaluated all of them. We now install SupaLite and WARMERroof exclusively, and we want to explain how they differ and when we recommend each one.
SupaLite vs WARMERroof - how they differ
Both are excellent systems and both are a significant step above the alternatives. The key difference is in how they are built.
SupaLite uses a lightweight aluminium frame with 185mm of humidity-proof insulation, achieving a U-value of 0.15 W/m²K as standard. It is precision-engineered off-site to your exact specifications, which makes for a fast, clean installation with no cutting required on site. Every roof is custom-built and the system is certified under Stroma for building regulations compliance.
WARMERroof uses a timber frame structure, built using a unique prefabricated modular pod system. The timber frame is a natural insulator and eliminates the cold bridging risk associated with aluminium frames, achieving an even lower U-value of 0.12 W/m²K. It comes with a 25-year manufacturing warranty and a 40-year tile warranty, and is LABC-approved for building regulations compliance.
Which one do we recommend?
For most straightforward conservatory roof replacements, SupaLite is our preferred system. It is lighter, faster to install, and the aluminium frame system is tried and tested across thousands of installations. The Sky Vista glazing panel option is also a particular strength if you want to retain overhead natural light.
WARMERroof is the system we recommend when thermal performance is the absolute priority – its 0.12 U-value is the best available in the market – or where timber is preferred over aluminium for structural or aesthetic reasons. It is also worth considering for larger, more complex roof spans where the timber frame’s on-site adaptability is an advantage.
We will advise on which system is right for your specific conservatory during the free onsite survey, based on the size, shape and condition of your existing structure.
Why we walked away from the cheaper systems
Over the years we have also been called out to jobs where a homeowner had already had a cheaper system fitted by another company.
The most common issue we see is what the industry calls a cladover roof, where insulation is attached to the existing conservatory roof structure and panelling is added on the inside to make it look solid.
We advise homeowners to avoid cladover roofs entirely, warning that they can result in the roof becoming structurally unsound and actually make the room hotter in summer.
If you are ever quoted a price that seems dramatically lower than others, it is worth asking whether you are being quoted for a genuine replacement system or a cladover. The difference matters enormously
How Much Does a Tiled Conservatory Roof Cost?
We want to be straightforward here because vague pricing information is one of the most frustrating things about researching this kind of project.
As a rough guide, tiled conservatory roof installation in Essex typically costs in the region of £1,100 to £1,300 per square metre. For a typical conservatory that means:
- 3m x 3m conservatory (9m²): approximately £10,620 plus VAT
- 4m x 3m conservatory (12m²): approximately £14,160 plus VAT
*This is a rough estimate, for accurate pricing please arrange a site visit.
Pricing can vary slightly depending on which system is right for your project – SupaLite and WARMERroof have different manufacturing and installation processes, and the complexity of your specific roof shape will also affect the final figure. We will provide a fixed quote covering both options where relevant during your free onsite survey, so you can make an informed decision without any hidden costs.
The factors that will move your price up or down are size and shape (a Victorian or P-shaped conservatory involves more complex cutting and fitting than a simple lean-to), tile and colour choice, whether you add roof windows or Sky Vista glazing panels, and the condition of your existing frame.
One thing we always say to customers: be cautious of quotes that are dramatically cheaper than others. In 15 years we have never seen a significantly cheaper quote that did not involve either a cladover system, inferior materials, or corners cut on the finishing details like fascias, soffits and guttering. A good installation should include all of those as standard.

Planning Permission and Building Regulations
This is the area where we see homeowners most confused, partly because planning permission and building regulations are two separate things that get conflated constantly, including by some installers who should know better.
Planning permission
In most cases you will not need planning permission. Replacing an existing conservatory roof with a tiled system falls under permitted development rights as long as the structure remains the same size and shape as your existing roof.
There are exceptions worth knowing about:
- Your property is a listed building or sits within a conservation area
- Your conservatory was originally built without the correct permissions
- The replacement roof would materially alter the appearance of the property beyond a like-for-like replacement
- Permitted development rights have been removed by your local council, which sometimes happens on newer housing developments
If you are in any doubt, the simplest step is to contact your local planning authority before work begins. It is a free call and gives you certainty. We can also advise based on what we commonly encounter across Essex.
Building Regulations
Whether building regulations apply depends on your specific setup. Generally, approval is not required if your conservatory remains separated from the main house by external-quality walls, windows or doors, and has its own independent heating system with separate controls.
Building regulations are more likely to apply if your conservatory is already integrated into the main living space, or if the new tiled roof would effectively make it a permanent habitable room. This is also something to consider if you are thinking about knocking through the dividing wall at the same time.
The good news is that both systems we install are fully building regulations compliant as standard.
SupaLite achieves a U-value of 0.15 W/m²K and is pre-approved by Stroma.
WARMERroof achieves an even lower U-value of 0.12 W/m²K and is LABC-approved, with in-house building control to streamline the approvals process.
Where building regulations approval is required, we handle the entire process on your behalf and provide you with all relevant certification and paperwork on completion.
The Installation Process
A typical tiled conservatory roof installation takes between five and eight days from start to finish, depending on the size and complexity of the conservatory and the system being installed.
The process covers removal of the existing roof, installation of the new structural frame and insulation layers, tiling, leadwork, new fascia, soffits and guttering, and internal plastering and electrics. The conservatory will be weathertight within the first couple of days, so there is no extended period where the structure is left exposed.
All waste from the old roof is removed as part of the installation, and the finished result is a fully plastered internal ceiling complete with new electrics – a finished room rather than a construction project requiring further work.
Natural Light: The Truth
We are going to be honest here because we think some installers gloss over this, and we have always found that customers appreciate a straight answer more than a reassuring one.
A tiled roof does reduce the amount of light entering from above compared to a glass or polycarbonate roof. If you are currently sitting under a fully glazed roof with light flooding in from above, the experience will change.
That said, the majority of customers tell us afterwards that the room feels brighter than they expected. Here is why.
When we install the new roof, the internal ceiling is plastered and finished in white, following the natural pitch of the roof to create a vaulted effect. That bright, reflective surface amplifies the natural light coming in through your conservatory’s existing windows and doors.
The result is an open, airy room rather than the dark space some people fear. We had a customer in Chelmsford recently who was so convinced she would miss the overhead light that she almost chose a glass roof instead. Three months after her tiled roof went in she got in touch to say it was brighter than her living room.
If maximising natural light is genuinely important to you, there are two options you can build into the design:
Roof windows are discreet skylights that sit flush with the roofline and bring daylight directly into the room. They integrate cleanly into the SupaLite system and are the option we recommend most often for customers who want more light.
Sky Vista glazing panels replace sections of tiling with full-length glazed panels, available with solar control glass to prevent the overheating associated with standard glass roofs. They give you the thermal performance of a tiled roof alongside significantly more overhead light.
We will show you examples of both during your free onsite survey and help you work out what is right for your space. For more on natural light and how different options compare, see our tiled conservatory roofs vs polycarbonate comparison.
How Long Does a Tiled Conservatory Roof Last?
The lifespan of a tiled conservatory roof depends on the system installed, but both options we offer are built for the long term.
SupaLite tiles carry an average life expectancy of 50 to 60 years, with a 25-year tile guarantee and 15-year manufacturer warranty. WARMERroof offers a 25-year manufacturing warranty and a 40-year tile warranty.
To put either figure in context, according to Checkatrade research a polycarbonate roof typically lasts between 10 and 20 years before performance declines significantly, with temperature control often becoming difficult after 10 to 15 years. A tiled roof can outlast polycarbonate three to four times over.
Glass roofs sit between the two, generally lasting 20 to 25 years before significant performance decline.
Both systems also come with a 10-year insurance-backed guarantee on workmanship from the installer. An insurance-backed guarantee means the investment is protected even if anything were to happen to the installing company — something not all installers offer and worth asking about when getting quotes from any company.

Common Myths About Tiled Conservatory Roofs - Debunked
Over 15 years we have heard the same concerns come up repeatedly. Here are the ones we want to address directly.
"A tiled roof will make my conservatory dark"
As we explained in Section 8, the white vaulted plastered ceiling reflects light from your existing windows effectively, and most customers are surprised by how bright the finished room feels. Optional roof windows and Sky Vista glazing panels are available if you want to maximise daylight further. For a deeper look at this, see our post on debunking myths about tiled conservatory roofs.
"My conservatory frame will not support the weight"
Modern tiled roof systems are specifically designed to address this concern. Both SupaLite and WARMERroof are lightweight systems – SupaLite weighs just 46kg/m² and WARMERroof uses a timber frame with a lightweight glulam ring beam designed to sit on existing conservatory frames. Either system is light enough to fit the vast majority of existing conservatory structures without structural alteration. A surveyor will assess the frame before any work is committed to.
"I will definitely need planning permission"
As covered in Section 6, most like-for-like roof replacements fall under permitted development and require no planning application. We will confirm the position for your specific property during the survey.
"It is too expensive to be worth it"
The upfront cost of a tiled roof is higher than polycarbonate or glass. But a polycarbonate roof that costs less today will likely need replacing at least twice in the time a tiled roof lasts once. Factor in the heating bills from a poorly insulated conservatory over 15 years, and the economics of a tiled roof look very different. Almost every customer we have spoken to who converted from polycarbonate tells us they wish they had done it sooner.
"The installation will be very disruptive"
In our experience, the disruption is much less than people expect. The conservatory is weathertight within the first couple of days, the work is contained to the conservatory structure itself, and most installations are complete within a week. We manage the full process so customers are not left coordinating separate trades.
Maintenance
One of the underrated benefits of a tiled roof is how little it needs once it is in place. Polycarbonate roofs need regular cleaning to prevent algae, discolouration and debris build-up in the channels. Glass roofs require periodic sealant checks and cleaning. A tiled roof, by contrast, is largely self-maintaining.
The basic checks we recommend are inspecting the tiles for any cracking or displacement after severe weather, keeping gutters and downspouts clear of debris, and confirming flashings and leadwork remain watertight during your annual maintenance check. Beyond that, the roof should look after itself for decades.
For a full guide to keeping your tiled conservatory roof in the best possible condition year-round, including seasonal maintenance tips and what to look out for, see our dedicated tiled conservatory roof maintenance guide.
Frequently Asked Questions
Will a tiled conservatory roof increase my home's value?
In most cases, yes. According to Eurocell’s Great British Conservatory Census, 60% of conservatory owners believe their conservatory adds value to their home. A tiled roof strengthens that case significantly because it converts the space from a seasonal room into usable year-round living space, which is how estate agents and buyers assess it. An outdated polycarbonate conservatory can actually reduce a property’s value by up to £15,000 according to some estimates – a tiled roof replacement directly addresses that risk. We always recommend speaking to your local estate agent for a view on the specific uplift in your area.
Can a tiled conservatory roof be installed in winter?
Yes. Unlike some home improvement projects that are weather-dependent, a tiled conservatory roof installation can be carried out year-round. The installation process moves quickly – your conservatory will be weathertight within the first couple of days – so exposure to the elements is minimal. Many customers actually choose winter installations specifically so the room is ready and warm to use by spring.
Do I need to empty my conservatory before installation?
We recommend clearing the conservatory of furniture and belongings before work begins, both to protect your possessions and to give our team full access to the structure. We will confirm exactly what is needed during the pre-installation survey. We handle all waste removal from the old roof, so you do not need to arrange a skip separately.
Can a tiled roof be fitted to any conservatory shape?
In the vast majority of cases, yes. SupaLite systems can be tailored to Victorian, Edwardian, lean-to, P-shaped, double-hipped and gable-ended conservatory styles, among others. Each roof is custom-built to your exact dimensions rather than cut from a standard template, which ensures a clean fit regardless of the shape or pitch of your existing structure. We will confirm suitability during the free onsite survey.
What colour tiles are available?
SupaLite offers two main tile ranges. ExtraLight Shingle tiles are available in Charcoal, Ember and Walnut, with a newer ExtraLight Classic option available in black for a more contemporary finish. Tapco slates are available in Stone Black, Pewter Grey, Chestnut Brown, Brick Red, Red Rock and Plum. In most cases we can find a colour that either matches or complements your existing roof tiles. We carry physical samples and will bring them to your survey so you can see the options against your property before committing.
Is it worth replacing a conservatory roof or should I just build a new extension?
For most homeowners a tiled roof replacement is significantly better value than demolishing the conservatory and building a new extension from scratch. According to SupaLite, a tiled roof replacement costs around £1,000 per square metre plus VAT, compared to approximately £3,000 per square metre plus VAT for a new home extension – making a roof replacement up to 60% cheaper for a comparable result. The disruption is also far less, with most roof replacements complete within a week compared to months for a full extension build. Unless your conservatory frame itself is structurally compromised, a tiled roof replacement will almost always deliver better value.
Why Choose Us?
We started this business over 15 years ago because we were frustrated with the standard of installation we were seeing from other companies in Essex. Poorly fitted roofs, subcontracted trades with no experience of conservatory systems, and workmanship guarantees that turned out to be worthless because the company behind them had folded.
We are a certified premium SupaLite installer and registered WARMERroof installer, one of a relatively small number of companies in Essex to install both systems. We manage every installation from survey to plastering in-house, and every job comes with a 10-year insurance-backed workmanship guarantee.
What our customers say:
“Fantastic job done by Greenoak, the guys were professional, friendly and a pleasure to have in my home. I couldn’t be happier with the job they did. Highly recommended.”
– Deborah
“We would like to say a huge thank you to all at Greenoak Concept and Design for installing our Superlite roof. We are so very pleased with it. We were looking to have the roof of our conservatory replaced because of a constant leak every time it rained. I don’t think we would have thought about it otherwise. But I have to say it is the best thing we ever did. It has turned our conservatory into a proper room. It is just so much warmer. We did a lot of research on line and was very impressed with the Superlite roof. We looked for a company that fitted it and found Greenoak and I am so glad we did. The service we received was first class.”
– Gillian
