Project Details
This ageing flat roof on a small retail complex was beginning to suffer from minor leaks and surface deterioration caused by prolonged weather exposure. A full roof replacement was not required, so a premium elastomeric coating system was applied to restore waterproofing, improve thermal performance, and extend the roof’s lifespan by more than a decade — without disrupting business operations.
What we did
This project focused on efficient restoration without unnecessary strip-out or disruption.
Initial inspection and assessment
We began with a comprehensive assessment of the existing roof system.
Identified surface cracking, blistering, and areas of standing water
Carried out moisture testing and core sampling
Confirmed the roof structure remained sound and suitable for coating
Produced documentation to support warranty requirements
Roof surface prep and repair
Proper preparation ensured long-lasting results.
Pressure washed the entire roof surface to remove dirt and debris
Repaired cracks and low areas using sealant and reinforcement mesh
Strengthened seams with seam tape and primer
Protected roof edges, outlets, and HVAC units prior to coating application
Coating application
The coating system was applied with precision.
Applied a commercial-grade acrylic elastomeric coating in multiple layers
Ensured complete coverage, particularly around roof penetrations and details
Created a seamless, fully waterproof protective layer
Completed final inspection and coating thickness checks for warranty compliance
Challenges we faced
As with most commercial projects, careful planning was required.
Roof access coordinated around business trading hours
Standing water areas addressed with levelling compounds
Weather conditions managed between primer and topcoat application
Why this project stands out
This project delivered a cost-effective alternative to full replacement.
Improved reflectivity supporting lower cooling costs
Waterproof protection for more than 10 additional years
No strip-out, allowing uninterrupted trading
Eligible for renewable manufacturer warranties
Final result
The newly coated roof is clean, fully protected, and ready to withstand ongoing weather exposure. The building is now safeguarded against leaks and future deterioration, with minimal disruption to the businesses below.
