Aintree University Hospital
Case Study
Laying the Groundwork
AAC Flat Roofing was invited to survey the existing canteen roof at Aintree University Hospital following a recommendation from an existing client. We started with:
- Designing an insulation scheme to achieve the target thermal performance.
- Developing a site-specific health and safety plan to meet both HSE and client standards.
- Performing windload calculations to ensure the right balance and type of fixings across the roof.
Collaboration That Made the Difference
From the outset, collaboration played a key role in defining the right approach. Following a full inspection, we recommended overlaying the existing roof rather than stripping it. This strategy reduced noise, avoided disruption to hospital operations, and provided a faster, more cost-effective solution.
By working closely with hospital representatives, we scheduled works to align with day-to-day activity, ensuring that essential services remained unaffected throughout the refurbishment.
Scope of Works
- Prepared the roof surface for the new system.
- Installed a mechanically fixed Protan SE membrane with a separation layer to prevent plasticiser migration.
- Completed works across an 800 m² roof area, including a drop-down gutter.
- Full mechanical fixing system to guarantee long-term durability and wind resistance.
Overcoming Challenges
The project began in early January, with cold and wet weather conditions adding complexity to the works. This refurbishment came with several constraints:
- Extending the roof’s lifespan without removing the existing system.
- Roof access was only possible once scaffolding was installed.
- Live hospital environment requiring careful planning to avoid disruption to patients and staff.
- Busy hospital location meant material deliveries and equipment handling had to be precisely coordinated.
How We Delivered
Our experienced installation team completed the entire refurbishment within 12 days, using a Protan PVC membrane system. Key aspects of our delivery included:
- Careful sequencing of daily work to minimise impact on hospital activity.
- High attention to detailing around roof penetrations and edge terminations.
- Constant quality assurance checks throughout the installation.
- Electronic testing to confirm performance before handover.
The project was independently signed off by Protan, confirming full compliance with manufacturer standards.
The Outcome
- 20-year manufacturer and AAC-backed warranty.
- A modern, long-term, low-maintenance roofing system.
- Extended roof service life without removing the existing system.
- Completed works with no disruption to hospital operations.
This project stands as an example of AAC Flat Roofing’s ability to deliver efficient, high-quality roofing solutions in live healthcare environments where precision and care are essential.
