What is roof restoration?
Roof restoration repairs damaged areas, primes surfaces, and applies a new waterproofing system. Instead of tearing off the entire roof, the structure is reinforced and resealed—restoring protection at a fraction of replacement costs.
How seamless membrane technology works
In this Christchurch project, the roof was primed and coated with a one-coat seamless membrane to a thickness of 1.0mm. Butynol areas received additional grey silicone layers at 1.5mm. This creates a continuous, leak-free surface with strong UV resistance.
Christchurch weather challenges
Nor’west winds, heavy rain, and strong UV rays push flat roofs to the limit. Seamless restoration avoids joins and overlaps—the weak points where leaks typically begin—making it ideal for Canterbury’s climate.
Before and after case study
Before: Damaged, weathered panels and leaks at seams.
During: Old surfaces primed, liquid membrane applied by licensed installers.
After: Smooth, watertight finish ready to handle decades of Christchurch weather.
The entire roof primed, then a one-coat Seamless Membrane in grey to a thickness of 1.0mm was applied to the panels. Grey liquid silicone was then applied to the Buytnol areas at a thickness of 1.5mm.
