The Problem
The customer contacted Cotswold Roofing & Guttering after experiencing continuous leaks from their existing flat roof.
The leaks had become increasingly difficult to manage and were beginning to affect the usability of the space below. Temporary measures had been attempted previously, but the problem continued returning during periods of rainfall.
Following inspection, it became clear that the existing flat roofing system had reached the point where localised repairs would not provide a reliable long-term solution.
The roof showed signs of ongoing water ingress and poor thermal performance, creating an opportunity to improve both weather protection and insulation at the same time.
Our Assessment
After carrying out a detailed inspection, we recommended a complete replacement of the existing flat roof rather than further patch repairs.
The project plan included:
- Removal of the existing roof covering
- Inspection and preparation of the roof deck
- Installation of upgraded insulation
- Installation of a new GRP flat roofing system
- Finishing and weatherproof detailing
By replacing the roof fully, we could eliminate the source of the leaks while improving the thermal efficiency of the structure.
The Solution
The old roofing materials were carefully removed to expose the roof structure beneath.
Once prepared, upgraded insulation was installed to improve heat retention and overall roof performance.
A new GRP flat roof system was then installed across the entire area.
GRP, also known as glass reinforced plastic roofing, creates a seamless waterproof finish that performs particularly well on flat roof applications. Its durability and low maintenance requirements make it a popular long-term solution for residential roofing projects.
Careful attention was given to edge detailing and drainage to ensure reliable water management moving forward.
The Result
The completed roof now provides a fully weatherproof finish and improved insulation performance.
The customer no longer experiences the persistent leaks that originally prompted the enquiry.
The upgraded roof delivers:
- A fully renewed waterproof surface
- Improved thermal performance
- Reduced risk of future water ingress
- A cleaner and more modern finish
- Greater long-term reliability
The customer now has confidence that the roof is protected and performing properly throughout the year.
