| Feature | Polycarbonate Roof | Thermaroof System (Tiled) |
| Winter Insulation | Often loses heat quickly; can feel like an icebox in the winter. A poorly insulated conservatory is absolutely freezing in winter, and this cold seeps into the house, making heating much less efficient. | 75% warmer; high-performance multifoil insulation retains heat. |
| Summer Temperature | Suffers from the “greenhouse effect”; it can become like a sauna in the summer | 75% cooler; blocks out solar radiation to maintain a pleasant climate. |
| Acoustics | Can be very noisy during heavy rain or wind. This can be very annoying, and is yet another reason why you can’t use your conservatory all year round. | Significantly quieter; the solid structure dampens the sound of rain. This makes your conservatory a complete living space. |
| Visual Comfort | Prone to harsh sun glare and UV exposure. Another aspect that makes your conservatory not appropriate for everyday living. | Eliminates glare, making the room ideal for watching TV or working. This makes your conservatory a complete living space. |
| Energy Efficiency | High heating costs due to poor thermal retention. This costs you money each year, and the property will be very difficult to sell. | Lower heating bills thanks to superior insulation and lower U-values. This saves you money on your energy bills and makes the property more attractive when it’s time to sell (also increasing its overall value). |
| Aesthetics | Often looks like a temporary “plastic” addition. | Feels like a seamless home extension with matching tile options. |
| Interior Finish | Basic internal appearance with visible rafters. | Bespoke internal finishes, including plastered ceilings and LED lighting. |
| Durability | Prone to discolouration and structural wear. Is prone to leaking and condensation, which can damage the conservatory even more. If the conservatory becomes too damaged, you may even need to replace the entire structure. | Long-term peace of mind with a 10-year installation guarantee. |

Is My Current Conservatory Roof Appropriate for a Tiled Roof Replacement?
The Thermaroof System is designed to suit all styles of conservatory roof, so you can replace a substandard old roof with an upgraded tiled roof. Your conservatory will be appropriate if it isn’t too damaged. If you find that your conservatory is too hot in the summer and too cold in the winter, is noisy, and leaks, then it will need to be replaced. When the conservatory is too damaged, it will likely need to be completely replaced. We always try to replace your conservatory roof before suggesting a full replacement. If your conservatory has these issues as well as a roof that isn’t up-to-standard, then you will likely have to consider a replacement:
- There is too much leaking and condensation, which has damaged the conservatory. The roof would patch things up, but this won’t stop these issues from further damaging the conservatory structure if the damage is too significant.
- The internal glazing has condensation within the glass, or the seals are severely damaged. This requires a complete replacement, which often isn’t possible, or it’s easier to rebuild the structure than patch up the old one.
- You don’t like the design of your current conservatory, and want to create a new style that suits you.
- There is significant structural damage that risks the conservatory breaking completely or failing in the future. You will want to take action and replace the conservatory before a serious structural issue occurs, forcing you to carry out urgent repairs which could have been avoided by being proactive.
What are the Benefits of Tiled Roofs?

You are investing in your home’s overall value and energy efficiency. You will save money on your energy bills instantly, whilst increasing the value of your home when you sell the property. Investing in homes is much more popular than buying a new one, and you can even use standard conservatories as living spaces and move an old room into the conservatory to create a new bedroom in a more insulated part of your property.
Making the Decision to Upgrade and The Common Signs You Need an Upgrade
If you have an older-style conservatory roof with polycarbonate, then you need to consider an immediate upgrade. You will have a conservatory that isn’t efficient, is wasting money on heating and that you can’t enjoy each year. Investing in a replacement conservatory roof will replace your current roof, save you money on energy bills, increase the value of your home, and make it easier to sell.
