Upgrading an Old Conservatory Roof in Hexham
This recent Hexham conservatory roof replacement project demonstrates how replacing an outdated polycarbonate roof with a modern insulated system can completely transform a conservatory.
The property, located in the historic town of Hexham in Northumberland, had a well-built conservatory structure that was still structurally sound. However, the original polycarbonate roofing system had reached the end of its life and was no longer providing the performance the homeowner needed.
Over the years, the roof had started to deteriorate and leaks had begun appearing during periods of heavy rainfall. At the same time, the conservatory suffered from major temperature fluctuations throughout the year.
During winter months, the room became extremely cold and uncomfortable, while in summer it would overheat quickly due to the lack of insulation. This meant the conservatory had gradually become an underused space within the home rather than the bright and welcoming room it was originally intended to be.
Situations like this are very common in older conservatories throughout Hexham and the wider Northumberland area, particularly those built with early polycarbonate roofing systems.
The Problems with the Existing Polycarbonate Roof
When our team at CSM Trade North East visited the property to carry out a survey, it quickly became clear that the conservatory roof was no longer performing effectively.
Polycarbonate roofing systems were widely used on conservatories in the past because they were lightweight and relatively inexpensive. However, they offer very limited insulation and often deteriorate over time.
The existing roof had begun to fail around several of the joints and fixings, allowing moisture to enter the structure during heavy rain.
The homeowner had experienced several ongoing issues including:
- Water ingress during heavy rainfall
- Cold draughts entering the conservatory
- Condensation building up on colder days
- Excessive heat in summer months
- Significant heat loss during winter
Because of these problems, the conservatory was only comfortable to use during certain times of the year. Instead of functioning as a natural extension of the home, the room had effectively become a seasonal space that was often avoided.
After discussing the available options with the homeowner, we recommended a complete conservatory roof replacement using a Guardian Warm Roof system.

Hexham Conservatory Roof Replacement – The Installation Process
The project began with the careful removal of the old polycarbonate roofing system.
Our team dismantled the existing roof panels and supporting components while ensuring the original conservatory base structure remained protected. Because the main structure of the conservatory was still in good condition, it was perfectly suitable for a modern roof upgrade.
Once the old roof had been removed, we began installing the new Guardian Warm Roof system, which is designed to provide significantly improved insulation and long-term durability.
The installation included:
- A structurally engineered insulated roof system
- High-performance insulation designed for thermal efficiency
- A solid tiled roof finish to match the property
- A professionally plastered internal ceiling
This type of system transforms the performance of a conservatory by replacing lightweight polycarbonate panels with a fully insulated roof structure.

Guardian Warm Roof – A Modern Conservatory Upgrade
The Guardian Warm Roof system has become one of the most popular conservatory roof replacement solutions in the United Kingdom.
Unlike older roofing systems, Guardian roofs are specifically designed to turn conservatories into comfortable, energy-efficient rooms that can be used throughout the year.
Key benefits include:
- Excellent insulation that keeps the room warm in winter
- Reduced heat build-up during summer
- A dramatic reduction in condensation
- Improved overall energy efficiency
- A clean plastered internal ceiling finish
- A tiled external roof that blends with the main property
Once installed, the conservatory no longer feels like a temporary structure attached to the house. Instead, it becomes a natural extension of the property.

The Finished Result
Once the installation was complete, the difference was immediately noticeable.
The new insulated roof eliminated the leaks that had previously caused concern, while the improved thermal performance created a far more comfortable living environment.
The conservatory is now:
- Warm during winter months
- Cooler and more comfortable during summer
- Free from condensation issues
- Energy efficient and well insulated
Externally, the tiled roof blends perfectly with the property, giving the conservatory a far more solid and permanent appearance.
Instead of feeling like a lightweight add-on, the room now looks and performs like a genuine extension of the home.
For the homeowner, this means the conservatory can finally be used as intended — a bright and relaxing space that can be enjoyed throughout the year.

Why Replace an Old Polycarbonate Conservatory Roof?
Many homeowners attempt temporary fixes when their conservatory roof begins to fail.
However, solutions such as adding blinds or internal boarding rarely solve the root cause of the problem.
Older polycarbonate roofs simply lack the insulation needed for modern energy efficiency standards.
Replacing the roof with an insulated system is often the most effective and cost-efficient long-term solution.
A modern conservatory roof replacement can:
- Improve thermal comfort
- Reduce heating costs
- Increase usable living space
- Enhance the overall appearance of the property
