Conservatory Roof Materials: Glass

When it comes to conservatory roof materials, glass is the traditional go-to product. However, it comes at a hefty price, and might not be the best choice for everyone. Before making your decision, it’s important to consider whether glass is right for you, and if this investment is going to be worth your money.

You can read more of the pros and cons of glass roofing when compared to polycarbonate here. Here are the main benefits and drawbacks to help you make the right choice.

The benefits of a glass roof

Glass is a highly popular choice when it comes to conservatory roofing, and for good reasons too. It comes with a whole host of benefits, including:

Better energy efficiency

Standard double glazing is equivalent in insulation to the thickest polycarbonate sheet. However, with modern innovations in glazing and glass, it is now possible to install insulating glass which is far more energy efficient than polycarbonate will ever be.

Reduced noise

With a polycarbonate roof, a rain shower can sound like someone practising their drumroll above your head. In heavy rain and hailstorms, it becomes impossible to hold a conversation in the conservatory. With a glass roof, there is no rain noise and your conservatory is a peaceful place to be in all weathers.

A beautiful view

Nothing compares to the uninterrupted view of the sky in all its glory. Being able to look up into a beautiful blue sky, a dramatic sky filled with storm clouds or into the starry night is what sells the glass roof above everything else.

Self cleaning

Your conservatory roof can now be fitted with self cleaning glass so that leaves, dirt and bird mess are no longer a pressing issue. With every rain shower, all the dirt will wash away, keeping your conservatory looking great for life.

Long lifespan

A typical polycarbonate roof will only last around 10 – 15 years, whereas your investment in a high quality glass roof will last a lifetime. It is more resistant to staining and to damage from the weather, so you shouldn’t need to replace it any time soon.

High security

Compared to polycarbonate roofs, glass roofs offer far more security protection than a plastic roof. Polycarbonate can be pushed through or cut relatively easily, whereas double or triple glazed, tempered glass is much harder to break.

Many people consider glass to be the only finish for their conservatory, thanks to the effortless elegance afforded by a glass roof. There are certainly a lot of benefits to be had wth this choice, but for more discussion on the pros and cons, this thread has some interesting opinions.

The drawbacks of a glass conservatory roof

Although there are a lot of reasons to love a glass conservatory roof, there are also some limitations to consider too:


Glass is heavy, so the conservatory structure will need to be specified to support the weight of the roof. If you are building a new conservatory, this shouldn’t be too much of an issue, but if you are upgrading from a polycarbonate roof, you may run into trouble. However, a good installer will structurally prove your conservatory and add strengthening where necessary.


A glass roof will cost several times more than a polycarbonate roof, and can send the cost of your build spiralling. If you get into triple glazing or special solar coatings, the price could be even higher too.

Requires blinds

As lovely as it is to see the sky and have the sunlight streaming in through the roof, sometimes the glare and heat can get a bit too much. This means that a glass roof could end up setting you back several hundred pounds for blinds too, so that your conservatory is usable in all weathers.

Time consuming

Because glass is harder to handle, the installation of your conservatory can take significantly longer than with a polycarbonate roof.

Weighing up the pros and cons of glass roofing for your conservatory will help you make the right decision for you. A lot of the choice will come down to personal preference, but do make sure you are well informed before jumping into an agreement with your installer.
