A Replacement Conservatory Roof

If your conservatory roof was built a long time ago, then it is most likely made from polycarbonate – which means that it is not energy-efficient and provides inadequate soundproofing.

A lot of homeowners are now looking to replace their polycarbonate conservatory roof with something that’s modern, stylish and will save them money on their heating costs.

Even if you don’t have a polycarbonate roof, it’s this part of a conservatory that deteriorates the fastest and is most likely to need replacing.

Rather than tearing down your extension – which, ostensibly, may have nothing else wrong with it – you would be better off exploring the cost of a replacement conservatory instead.

How much is a replacement conservatory roof? This will depend on the style of conservatory and the type of roof that you want.

As a broad guide, you should be looking to spend between £2000 and £9000 for a replacement conservatory roof. At the lower end of the scale you are paying for Lean-to conservatory roof measuring 2500 x 3000mm – and, at the latter end, a Lantern conservatory roof that’s 5000mm x 5000mm.

But before we start to talk about the different styles of conservatory roof, and other aspects of the design process – such as materials and doors and windows – we need to consider a much more important question: can I replace my conservatory roof?

Can I Replace my Conservatory Roof?

Although planning permission regulations were relaxed slightly in October 2008 – meaning that conservatories were newly regarded as permissible developments – there are still some legal loopholes you need to jump through when trying to get consent for a replacement conservatory roof.

Why isn’t it as straightforward as just asking a local installer to remove the existing conservatory roof and replace it?

Let’s discuss.

Do you need new foundations for your conservatory?

Your conservatory was designed to bear the load of your current roof. The replacement roof that you’ve chosen may be too heavy; if it is – and your chosen installer goes ahead with the work anyway – it could collapse and cause damage to your property or even a person.

Regardless of whether you own a Victorian, Edwardian or lean-to conservatory, you’ll need to step through a series of check before work on your extension can commence.
Your conservatory checklist should include:

Looking at the foundations. Can they withstand the weight of the proposed roof? To find out whether it can, your conservatory installer will need to excavate part of the base by drilling some trial holes into its structure.

Some issues that might arise are: (i) your conservatory is built over or near to tree roots/drainage; (ii) it is sited on filled ground.

If it passes the foundation test, does this mean you’ll get planning permission for a conservatory with a roof? It’s a step in the right direction – but you’ll also need to be able to prove that the rest of the structure can bear the load of your conservatory roof too.

What Conservatories are Exempt from Building Regulations?

If your conservatory was built before the new 2008 regulations were introduced, it may no longer comply with current rules.

If you want to replace a conservatory roof then it – and the structure it is built on to – will need to be compliant.

For example, is your extension sufficiently glazed? If you are building a solid conservatory roof, this will reduce the amount of glazing and could affect your ability to secure consent to go ahead.

Use the Government’s Online Planning Portal

Getting planning permission for a conservatory roof isn’t easy. Rather than going it alone, visit the government’s online planning website and look for the information you need.

You can find your nearest Local Planning Authority this way, search for accredited installers and even submit your application.

Types of Conservatory Roof

Before you get to the conservatory planning permission stage, you’ll need to do some research surrounding the different styles available. Solid conservatory roofs are an incredibly popular option.

Once you have chosen a conservatory design that ticks all the boxes, you can choose your roof.

Here is a breakdown of the different types of conservatory roofs, which will hopefully help you to make an informed choice.

Lean-to Conservatory Roof
Lean-to conservatory roofs complement properties that have low rooflines. They utilise a framework terrace style, with the glass being secured in place via a series of supports that can be either UPVC or aluminium.

The Lean-to conservatory roof slants down at an angle, which helps to create a better sense of interior space (making it an ideal choice for you if you’ve been searching for small conservatory ideas).

A Lean-to conservatory roof can be single- or double-hipped. What is a hipped roof? It has no gables or other vertical sides; instead, each side slopes down in the direction of the wall without the intervention of, say, a gable.

Victorian Conservatory Roof

The Victorian conservatory roof – like the last two styles mentioned – can be hipped- or double hipped. One of the most appealing aspects of its design is its steep pitch that slopes upwards from the sides.

Its classic design is enduring and has made it one of the most popular and enduring conservatory roof styles available.

Edwardian Conservatory Roof

Just like a Lean-to, the Edwardian conservatory roof slopes downward to create a spacious vaulted ceiling. Edwardian conservatory roofs are flexible in design, which means they can be modified to work with most types of property.

If there is a height restriction then it is possible to use the aforementioned double-hipped style roof to circumvent the problem – meaning that its ridge would be higher and a bit more like one you’d find on a conventional house.

Apex Conservatory Roof/Gable Conservatory Roof

The gable conservatory roof design is striking, whichever way you look at it. It is characterised by a two roof sections that join in the middle to form a triangle, whilst other conservatory roof styles – like the Lean-to and the Edwardian – can be adapted to meet the demands of all different types of properties, this design is best suited to homes that have high ceilings.

A low-ceilinged dwelling might be able to accommodate the Gable conservatory roof design; but you would need to speak to your installer about how this could be achieved.

A double-hipped conservatory roof – combined with what’s termed as a box gutter – might help you to achieve your perfect fit.

Conservatory Roof Materials

Once you’ve selected your preferred conservatory roof style, it’s time to start thinking about the most suitable roof materials for the job.

Although budget will influence the type of conservatory roof material you buy, you’ll also want to make sure that your selection adds value to your extension – rather than making it look cheap.

UPVC Conservatory Roofs

UPVC roofs for conservatories continue to be a popular choice. This could be due to their price – (UPVC conservatory roof costs are less expensive than timber framed or aluminium ones) – or because they are easy to clean and extremely robust.

You don’t have to settle for white UPVC frames either (although this colour is popular); it’s possible to choose from a range of different hues – including anthracite and timber.

How Much Do UPVC Conservatory Roofs Cost?

At least £18000 and perhaps as much as £5000. A replacement UPVC conservatory roof won’t break the bank – but there are other options available if your budget is flexible.

Timber Conservatory Roofs

If you already use timber framed windows in your main property, you’ll probably want to continue this theme when building your conservatory. Softwood is not as good as hardwood – so opt for the latter of these and ensure they are properly lacquered, so that they can withstand the elements.

A timber framed conservatory roof can be painted to meet your design requirements and, if looked after well, can last for years. If poorly maintained, it can become prone to rotting and warping.

How Much Do Timber Frame Conservatory Roofs Cost?

Expect to pay about 30% more than UPVC for a replacement wooden conservatory roof.

Aluminium Conservatory Roof

Aluminium is much stronger than UPVC or wood. If you can afford it, buying a replacement aluminium conservatory roof is your best choice; especially if you want a clean, minimalist look for your design.

Because it is such a malleable material, aluminium can be used not just in your replacement conservatory roof – but your windows too. The fine fenestrated effects they produce will give you a clear vision of the sky and your garden too.

Aluminium Conservatory Roof Cost

A replacement aluminium conservatory roof is roughly double the cost of UPVC.

Glass Conservatory Roof or Polycarbonate?

In fact, a replacement glass conservatory roof isn’t the only type you can choose over polycarbonate. But we would not recommend buying polycarbonate conservatory roof unless you are operating on a restricted budget.

This particular style is renowned as a poor insulator and sound proofer in comparison to the other conservatory roofing options that are available.

Replacement glass conservatory roofs have gas pumped in between their panes, which acts as an insulating barrier that stops too much heat from escaping. This will help keep your conservatory warm all day and all year long.

You can even buy tinted and self cleaning conservatory glass – (that’s right: no more standing on a step ladder with a squeegee!)

A replacement tiled conservatory roof would be even more thermally efficient and quieter than the glass alternative.

Be careful, though. Building regulatory approval may be needed if you decide to replace your polycarbonate or glass conservatory roof with a solid one – that’s because it will then be deemed as a permanent structure.

Conservatory decorating ideas

Now that you’ve chosen the best replacement conservatory roof, you can start to think about your decorating options.

Conservatory Furniture

Rattan is a lot like bamboo and highly durable – it can also look quite stylish. It will set you back anywhere from £250 through to several hundreds of pounds. It is superior to wicker conservatory furniture, which will become threadbare very quickly. And you don’t want to use standard home products either, as they will quickly fade in all that sunlight.

Having spent so much time choosing your replacement conservatory roof, these final details are important. What about iron patio conservatory furniture? It is designed to last and could look fantastic in the right setting.

Conservatory Blinds

Roller blinds are inexpensive but are always within your sightline. They can fade with time too and bugs can get stuck to them.

Aluminium conservatory blinds are pricier but will last longer and won’t obstruct your view of your garden too much – why scrimp when you’ve invested so much money in a new conservatory roof?

Conservatory Lighting

To avoid glare, use some form of lighting outside of the conservatory. This will stop people focussing on the glass and will also help reduce glare – which can be quite discomfiting when exposed to it for too long.

Conservatory or Orangery?

Traditionally, conservatories are built using lots of glass and less mortar and brick. An orangery is the exact opposite.

It is constructed mostly from brick, utilises pillars, and has a heavier closed-in look – which lends itself to privacy more than a conservatory does. But tradition no longer holds sway.

The difference between a conservatory and orangery these two types of construction is rapidly blurring, with homeowners designing bespoke orangeries with glass frontages, bi-folding doors and glazed lantern roofs. For some unique orangery ideas and costs, get in contact.


How much is a conservatory?

The cost will vary from between £6000 (for a small Lean-to conservatory) through to as much as £20,000 for a large P-shaped design with all the best accoutrements.

Conservatory prices will also vary depending on where you live and whether you use a local installer or a national one. If you already have a conservatory, don’t assume you have to replace it.

You could buy a replacement conservatory roof for as little as £2500 – so it pays to look at all the available options.

Planning Permission for Conservatories?

Inevitably, there will be instances where conservatory planning permission is needed. If you want to extend a barn, maisonette, or listed building, then you will have to do more to satisfy your Local Planning Authority that your proposed design adheres to both planning permission and building regulations. If you are replacing part of your conservatory then it may no longer be exempt – meaning you’ll have to prove adherence to a strict set of criteria.

Since October 2008, though, conservatories have been viewed by LPA’s as permissible developments, so you should be fine.

What Conservatory Style is Best?

It’s more a case of which conservatory style is right for your property. If you have a small mid terraced house, then a P-shaped conservatory won’t wrap around your dwelling as it’s designed too – and, even it could, there probably wouldn’t be enough room. A Lean-to conservatory would work perfectly and could be fitted with bi-folding doors and a glass roof to let in as much light as possible. Shop around for different conservatory ideas – you’re bound to find something you like.

What is a Trickle Vent?

It is a fine aperture drilled in your window at the top. A retractable slide can then be used to control the ventilation within your conservatory, thereby ensuring you maintain an appropriate climate that won’t encourage damp or condensation.

Trickle vents are now required in order to comply with building regulations – so you’ll need to make sure any new windows that you have fitted come complete with trickle vents, otherwise you could run into trouble with your Local Planning Authority.
