Replacement Conservatory Roofs

  • Is your conservatory not working for you anymore? Finding it too hot in summer and freezing cold in winter? Or simply just not enjoying how your conservatory looks next to your house anymore? There are easy ways to replace elements of your conservatory to fix these problems. We offer a range of different options to upgrade your conservatory, all of which can be tailored to your budget and requirements. 

    Multi-chamber Polycarbonate is a great material to use to upgrade your conservatory roof in a cost-effective way. This material has a modern finish and is much more insulative than older conservatory roofs. This hassle-free replacement will mean that during winter your conservatory will feel warmer and in the summer months will feel cooler.

    A glass conservatory roof replacement could also make a positive difference to your current conservatory. Our double or triple glazed high-performing glass is able to reflect as much as 78% of the heat from the sun and has U values as low as 0.8, creating a very insulated environment. 

    At CTG, we also offer self-cleaning glass, helping you keep your conservatory bright and free of debris. The thin coat of titanium dioxide which is applied onto this glass makes it very difficult for dirt to stick to the surface. Rain also will move quickly across this glass and not leave any residue or watermarks. 

    For the best conservatory performance, you should consider a full or partially tiled solution. This solution can often weigh less than your current glass roof and can be fitted easily to an existing structure. Our products can be altered to adjust the amount of heat and light you want in your conservatory, especially our Livinroof and Ultrasky products. By having a tiled roof, you are essentially getting a living room extension without the high price point. 

    A conservatory is a great way to add space to your home – often without the hassle of planning permission or the cost of a normal extension. Our replacement roofs are a great way to revamp your existing conservatory.

Common Questions

Can I replace my conservatory roof with a tiled roof?

If you are tired of your glass or polycarbonate roof and you’re looking for a change, you might be considering installing a tiled roof onto your conservatory. Thankfully, this is much easier than most people think. The tiles we use are exceptionally lightweight and can even weigh less than your current glass roof. To be on the safe side, we always send a surveyor to your property to ensure that your conservatory has the structural integrity to be able to hold up one of our stylish tiled roofs. If you’re unsure whether a fully tiled roof is the right solution for you, then take a look at these Ultraroof options, where you can choose which sections to remain glass and which sections to tile over. Get the best of both worlds and turn your conservatory into an integral part of your home – contact us today.

Do I need to replace my conservatory roof?

Although there isn’t a specific time limit when all conservatory roofs need to be replaced by, there are various ways you can tell if your conservatory roof needs an upgrade. Most conservatory roofs should last pretty well for a minimum of 15 years, but depending on the quality of the materials and the expertise of the installer, it could be much more – or much less. Keep an eye out for telltale signs your conservatory roof might need replacing:

  • There is moss or algae growing on the roof
  • There is more noise pollution than there used to be
  • You can feel draughts or cold spots
  • You have to turn the heating up to stay warm

If you are noticing any of these, then it might be worth considering a new conservatory roof. Contact us today to find out more about what we can offer you.

Does insulating a conservatory roof work?

DIY insulation projects for conservatory roofs are invariably inefficient and won’t last very long at all. We don’t offer this service either, for the same reasons; we’d rather give you a better solution that will give you more thermal efficiency and will last significantly longer. We’d recommend replacing your conservatory roof, either with modern, energy-efficient glass or a tiled roof. Both come with a 10-year manufacturer’s warranty, so you can enjoy your space for years to come. If your conservatory is freezing cold in winter, contact us today to see what solutions we have for you.

What is the best roof for a conservatory?

Construction materials have developed so much in the last few years that there are a variety of options available to you if you want to replace your conservatory roof. Your cheapest option will be polycarbonate, which has fairly good insulation properties but won’t last as long as our other options. A thermally-efficient, toughened glass roof from CTG is much more durable, and the high-performance double glazing keeps you warm even in winter while giving you maximum light from the sun. We can treat the glass depending on your needs, including UV filters, Stadip Silence sound reduction, and self-cleaning glass. If you’re looking for a sturdier option that offers shade in the summer, then why not consider a tiled roof? It gives the best thermal efficiency and you can add a lantern roof or roof windows for the best of both worlds.

Features and benefits

Guarantees you can depend on.

We have built up a great reputation over years of delivering a first class service and excellent products, all from our local, no nonsense all-about-you company.

From characteristic country cottages to contemporary town houses, we’re confident that our products will offer a style and finish to truly transform your home. Through constant innovation the quality, durability and security of our products is genuinely second to none. As a local company we are proud to offer British Standards BS7412/PAS24 for enhanced security.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.
