Putting A Roof On A Conservatory: The Ultimate Guide and FAQ

Putting a roof on a conservatory could change the look, feel, and performance of your extension. Converting one conservatory roof to a better roof adds monetary value to your home, improves the aesthetics of the space, and can make a big difference to your energy bills.

In this guide, we’re going to show you three things:

Replacing your conservatory roof should definitely be high on your home improvement checklist.

Let’s get started by looking at all the options available to you.

What is the best replacement conservatory roof?

The best conservatories feature roofs that achieve success in three areas: cost, looks, and comfort.

There are four main types of conservatory roofs:

How do these four types stack up in terms of cost, looks, and comfort?

Polycarbonate lean-to roof


Polycarbonate roofs with uPVC framing are the cheapest option but they suffer from fewer style options, poor energy performance, and loss of comfort in the hottest and coldest seasons. However, they can be a perfect choice for smaller, lean-to style conservatories.

Conservatory glass roof revamp your conservatory


Classic glass roofs are a step up from polycarbonate roofs. Glass roofs, especially double-glazed roofs, can be more energy efficient. The superior strength of glass panels increases the style options. Glass roofs can be brilliant for small spaces or as a connection to a beautiful garden.



A solid conservatory roof isn't necessarily all roof and no sun. Instead, our LivinRoof designs come with dozens of different panel options. These are very attractive, feature excellent energy efficiency, and will transform your conservatory's comfort level.

The tiled conservatory roof is the best option for thermal efficiency and added value. UltraRoof, our premium brand, incorporates many panel options to create beautiful designs that add comfort, performance, and value to your conservatory.

Replacement Conservatory Roof Prices

Conservatory roof cost depends on loads of factors, but we can make some general guides. Moving from least expensive to most expensive, the conservatory roof price for different materials is polycarbonate, glass, solid roofs, and then tiled roofs. Framing options add costs as well. The least expensive framing is uPVC, while aluminium, brick, and timber are more expensive.

Those are too general, though. What you need are some estimates. Our blanket estimation is £700 per square metre. We don’t charge more for smaller conservatories or more for larger conservatories. This is our rough estimate for all jobs.

Replacement conservatory roof costs

Is it worth replacing my conservatory roof?

Cost isn’t the only consideration, and maybe not even the most important one. Your conservatory is part of your home. If you can’t enjoy it fully due to declining performance, outdated styling, or anxiety about the next energy bill, then you should replace the roof.

Tiled roofs and solid roofs increase the value of homes. Converting a conservatory roof to a tiled roof or a roof with a solid surface, such as the LivinRoof, will boost your home’s value. However, the increase will probably not be higher than the cost of installation.

How to Replace a Roof

Replacing, converting, or upgrading your conservatory roof is a big job. While some homeowners can do this themselves, we recommend hiring a professional. Professional installers know how to make the best choices for your home, and their work is less likely to leak or present maintenance problems later down the road.

Let’s walk through the steps for replacing your roof.

Evaluate Your Existing Conservatory and Choose the Replacement

Considerations such as cost, style, energy efficiency, and space will affect the replacement roof you choose. Your new roof should blend in with your windows and doors and make your home more attractive, welcoming, and easier to maintain.

One major thing to consider is how the existing structure can be used for your new roof. Conservatory repairs and upgrades can often use the existing walls and structure, which saves money. However, if your new roof is likely to be a lot heavier than your old roof, then you may need to build new walls and a base.

A licensed installer should be able to help you make start your project by choosing the perfect roof. Conservatory projects that begin with good planning are much more likely to succeed.

Order the New Parts and Stage the Installation

Staging the work properly means your conservatory windows, heating system, and roof are all ready to go at the same time. This might seem like a minor point, but failure to plan creates delays, waste, and frustration.

Disassemble the Old Roof

The first real work is the removal of the previous roof. There are a few considerations for this step:

  • No homeowner should be left with a pile of rubbish to clear away. The installer should remove any waste from the site.
  • Taking down an old ceiling isn’t that difficult, but care should be taken to avoid damaging the main home, anything connected to the room, and any quality walls that will be incorporated in the new build.
  • Any necessary planning permission, materials delivery, and job site preparation should be completed before the old roof is removed because your home should always be weathertight.

Once the old roof is off, then work can begin on the new roof.

Building the New Roof

Constructing the new roof isn’t a super complicated job, but our expert installers know the right tips and tricks to get the job done perfectly the first time. Here’s what the process looks like:

  • Measure everything twice, lay everything out so that it is easy to see what parts go where, preparation is key to a nice fast installation.
  • Silicone the tops of the window and door frames and fit the eaves beam, seal any gaps where the windows and doors are screwed together, this will prevent water ingress later down the line.
  • Install the ridge and make sure that the critical measurements are all correct before installing glazing bars or hips depending on the style of replacement conservatory roof you have chosen
  • Once all measurements have been checked the rest of the roof can be installed, before glazing or tiling it is wise to chase out for the required lead work, this prevents glazing panels and tiles from getting scratched.
  • The lead can be fitted to the host walls ready to be dressed when the glazing or tiles have been fitted.
    Every style of roof has different methods or procedures that need to be followed to ensure a decent, leak-free installation.

A solid conservatory roof can be made of metal plates or glass frames fixed into a sturdy structure. LivinRoof panels are insulated to provide the insulation benefits of a tiled roof with no expensive conservatory structure. These provide much greater temperature control because of the insulation.

A modern glass roof will also make a conservatory warmer because of the double glazing or even triple glazing construction of the windows. A glass roof replacement with extra layers of glazing will be a big step forward for homes with older conservatories.

In some cases, you do not need planning permission to change a conservatory to an extension. However, it is always best to check with your local council and follow their regulations.

Conservatories are considered ‘permitted developments.’ These home improvements can usually be built without planning permission. Converting the roof does not normally need permission, either. However, if the space is being enlarged, then you should check with your council.

Reputable installers should be able to advise you on the best course of action.

Yes, we’re sure many people can replace their own conservatory roofs. The tools needed aren’t extensive and some conservatory roof options come with many prefabricated parts. With the right conservatory design, replacing your conservatory roof yourself might be a good idea.

We still recommend you hire a professional. There are a few reasons for this:

  • An experienced installer can finish your installation quickly, with little or no mess to clean up when they are finished.
  • Adding a solid roof can require extra expertise. A conservatory installer should know the best way to achieve your perfect look.

Yes, you can put a flat roof on a conservatory. Conservatories with flat roofs might be ideal for homes with overlooking windows, bungalows, or homes where height is an issue. Homeowners considering a flat roof should look into how to prevent leaks and drips. With the right materials and structures, flat roofs can be gorgeous and hassle-free.

Any work done on your home should meet building regulations. These are not the same as planning permission. Building regulations are in place to protect homeowners from shoddy construction and substandard work. You should insist on your installer working according to the most up-to-date building regulations.

For planning permission information, log into your council’s planning portal. They should have any information you need when replacing a conservatory roof.
