This building was suffering from multiple leaks due to the roof lights and the guttering. We gave the roof area a complete overhaul with brand new guttering and roof over system that eliminated all the issues and gave our customer a 5 year warranty.
Southampton’s Industrial Shift
Once defined by its docks and maritime legacy, Southampton’s industrial landscape is evolving fast. A growing logistics hub for the south coast, the city is seeing renewed investment in modern warehousing, light manufacturing and energy-efficient retro-fits. Developers and property owners are prioritising infrastructure upgrades, especially roofing and cladding (to meet stricter environmental regulations and appeal to green-conscious tenants). Roof-over systems and insulated panel replacements are among the top retro-fit solutions being deployed to extend asset life without major disruption.
Complete Roofing Overhaul Eliminates Persistent Leaks at Industrial Site
A large industrial facility in Southampton needing a critical roofing upgrade after the building began experiencing significant water ingress. The 2,000 square metre roof was plagued by ongoing leaks, primarily due to deteriorated roof lights and failing guttering systems.
These issues had started to disrupt daily operations and raised long-term concerns about water damage to the building’s infrastructure and contents.
Identifying the Problem
Upon inspection, the main sources of the leaks were found to be:
- Ageing roof lights, which had become brittle and no longer sealed properly
- Clogged and corroded guttering, unable to cope with runoff during heavy rainfall
- General wear of the existing roof surface, increasing the risk of further failure
These combined factors led to patchwork repairs over the years, but a full-scale solution was necessary to restore performance and protect the asset long term.
The Roof-Over Solution
Instead of opting for a costly and disruptive full roof removal, our team proposed a roof–over system (a modern approach that involves constructing a new roofing layer over the existing one). This method not only contains potential asbestos risks without immediate removal but also provides;
- Thermal and acoustic insulation improvements
- Minimised business disruption – as internal operations continued during installation
- Extended lifespan of the building envelope
The roof-over system was paired with a completely new guttering installation, ensuring efficient water runoff and eliminating the root cause of many of the historic leaks.
Rethinking Industrial Roof Upgrades
Roof-over systems aren’t just a quick fix, they’re increasingly seen as a strategic upgrade in facilities management. By layering modern, high-performance materials over outdated or compromised roofs, companies avoid the operational downtime and environmental burden of full roof strip-outs. For businesses in sectors with strict compliance standards or temperature-sensitive operations, a well-executed roof-over can offer immediate gains in insulation, weather resilience, and energy savings, all without disrupting what’s happening below. In areas like Southampton, where coastal weather can accelerate wear, this approach balances practicality with long-term performance.
Results Delivered
The project was completed on time and to specification, with all works carried out in accordance with current building regulations and health & safety standards. The client was issued a 5-year workmanship warranty, offering peace of mind and assurance that the building is protected against future weather-related issues.
Key Project Highlights:
📍 Location: Southampton, UK
📐 Roof Area: 2,000 sqm
🔧 Scope: Roof-over system + full gutter replacement
🛠️ Problem Solved: Leaks from roof lights and gutters
✅ Warranty: 5 years on workmanship
This project showcases our modern roofing techniques and expert workmanship. This project helped our client reduce long-term maintenance costs while significantly improving building performance and energy efficiency.
Did you know?
Installing a roof-over system doesn’t just address leaks—it can also improve energy efficiency. By adding a new insulated layer above the existing roof, heat loss through the roof can be reduced by as much as 25%, easing pressure on HVAC systems and lowering long-term energy costs. For large-scale industrial buildings like the 2,000 sqm facility in Southampton, this translates into meaningful savings and more stable interior temperatures throughout the year.
