Turning an Unused Garage into a Practical Space in Gosforth
This recent garage transformation in Gosforth demonstrates how an ageing and unused garage can be brought back to life with the right improvements.
The property owner contacted CSM Trade North East after years of leaving the garage unused. Like many older garages across the North East, the structure had slowly deteriorated over time and had become little more than a storage area for items that were rarely accessed.
The garage had not been used properly for over a decade. The roof was leaking, the timber window frame had begun to rot and the original metal up-and-over garage door was rusting badly. Inside, the space felt cold, damp and uninviting.
The homeowner did not want a full garage conversion into a living room or office. Instead, they wanted to make the garage dry, secure and practical again, so it could be used as a functional storage space or workshop all year round.
The Problems with the Existing Garage
During our survey, our team identified several issues affecting the garage.
Older garages often suffer from a combination of roofing, ventilation and access problems, and this property was no exception.
The main issues included:
- A failing felt roof that was allowing water ingress
- A rotten timber window frame
- A rusting metal up-and-over garage door
- No insulation or thermal protection
- No internal access door into the property
The most serious issue was the roof.
The old felt roofing system had reached the end of its lifespan and had begun to break down. Once felt roofs start to deteriorate, they often crack and allow moisture to penetrate the structure. Over time this can lead to damp conditions inside the garage and even structural damage to the timber beneath.
To resolve these issues properly, the garage required a comprehensive upgrade rather than simhttps://csmtrade.co.uk/garage-conversion/ple repairs.
Installing a Modern EPDM Rubber Roofing System
The first stage of the project involved removing the failing roof covering and preparing the structure for a new installation.
Our team stripped the existing roof back to the deck and installed a high-performance EPDM rubber roofing system.
EPDM has become one of the most reliable roofing materials available for garages and flat roofs.
Unlike traditional felt roofing, EPDM rubber membranes offer several advantages:
- Excellent waterproofing performance
- Long lifespan and durability
- Resistance to cracking and blistering
- Low maintenance requirements
- Strong resistance to weather and UV exposure
This modern roofing solution provides long-term protection against water ingress, ensuring the garage remains dry and protected for many years.

Roofline Replacement for Long-Term Protection
While installing the new roof, we also replaced the existing roofline components to ensure the entire structure was properly sealed and protected.
Upgrading the fascia, soffits and drainage elements of the roofline helps prevent water from entering the roof structure and keeps the installation looking neat and modern.
Replacing the roofline at the same time as the roof ensures a consistent finish and eliminates future maintenance concerns.

Upgrading the Window for Security and Efficiency
The old timber window frame had begun to rot due to prolonged exposure to moisture.
Timber windows can deteriorate quickly when located in garages, especially when roofing issues allow damp conditions to develop.
To resolve this, we removed the existing window and installed a new Rhea A-rated window.
This upgrade improved both:
- Security
- Thermal performance
The new window also allows more natural light into the garage, making the space feel brighter and more welcoming.
Electric Roller Shutter Installation
One of the most noticeable upgrades in this project was the installation of a black electric thermal roller shutter door.
The original metal up-and-over door had begun to rust and offered very little insulation.
The new roller shutter door provides several advantages:
- Improved thermal insulation
- Enhanced security
- Smooth electric operation
- A modern appearance
Because the garage does not have a separate internal access door, we installed the roller shutter with additional safety features.
These included:
- A safety edge system to prevent accidental closure
- An external manual override, allowing the door to be opened safely during a power cut
This ensures the garage remains accessible even if electricity is temporarily unavailable.
The Finished Garage Transformation
Once all work was completed, the transformation was dramatic.
The garage had been completely revitalised and now provides a practical and secure space that can be used every day.
The upgraded garage is now:
- Fully watertight
- Thermally improved
- Secure and modern
- Clean and visually appealing
- Suitable for year-round use
Instead of being a damp and neglected area, the garage is now a functional and valuable part of the property once again.
Projects like this show that garages do not always require a full conversion to make them useful.
Sometimes, upgrading the roofing, windows and access points can completely change how the space functions.
