At Roof Auckland, we take pride in delivering safe, compliant, and quality roofing solutions for large-scale commercial sites. Our recent project at Countdown Birkenhead demonstrates our expertise in managing complex re-roofing while minimising disruption to operations.
The Challenge
The existing roof at Countdown Birkenhead presented multiple challenges:
-
Extensive rust requiring treatment before installation of the new system
-
Old clear sheets needing replacement to maintain light transmission while ensuring safety
-
AC units, ducting, and timber walkways requiring removal or modification
-
Tight access, high wind zone, and proximity to live food preparation areas demanding strict health and safety management
-
Move the cell phone tower and cables to accommodate the re-roofing process.
Our Solution
With the challenges laid out, our first priority was to ensure a safe and compliant approach while minimising impacts on the store’s operations. We began with a full roof wash and rust treatment, followed by careful disconnect all vents, ducting and AC units in collaboration with EconoMech. To address structural constraints, we installed a TPO recovery system overlay in areas with insufficient height and applied a TPO membrane to the internal gutters for complete waterproofing. We then supplied and installed the new Colorcote Magnaflow DP955 roofing in Titania, chosen for its durability and clean modern finish, along with new flashings, and trafficable clear sheets to maintain natural light.
Throughout the project, we worked seamlessly with architects, engineers, and multiple contractors to ensure every detail was executed to plan. By scheduling crane and Hiab operations after hours, we were able to minimise disruption to Countdown’s daily business and keep the supermarket operational.
For the cell phone towers, our team re-roofed the rear area using BB900. This avoided the need to move the mounted equipment, allowing work to proceed efficiently while keeping the supermarket connected. It shows how we adapt quickly to unexpected site constraints.
Results
The completed project delivered a watertight, structurally sound, and fully compliant roof system. It has improved safety and performance with new roofing and cladding profiles that will stand the test of time.
Despite tight timelines, complex penetrations, and operational constraints, our team ensured every step met highest standards. The result is a safer, stronger roof system designed to protect the building and its occupants for years to come.
