Equus Soprema Membranes: Waterproofing Solutions for Flat Roofs


Roof Waterproofing with Equus

When considering membrane waterproofing for your flat roof, choosing the right solution is crucial. The correct waterproofing will ensure long-term protection against water damage, which can lead to structural deterioration, mould growth, and costly repairs.

At Equus we believe that one system does not fit all, and we have always prided ourselves of our range of waterproofing solutions. Along with our partners at SOPREMA, we offer four sheet membrane roofing systems that offer effective waterproofing, improve energy efficiency, and enhance the overall durability and lifespan of roofs. Selecting the right solution tailored to the specific climate, roof type, budget, building and end-use requirements is essential for optimal performance and reliability.

All our roofing membrane systems are available as an Equus Soprema Warm Roof

A Warm Roof system combines a UV-resistant waterproofing membrane with thermal insulation, and a vapour barrier, protecting the building from water ingress while increasing the building’s thermal properties and controlling condensation. The warm roof helps to maintain a consistent internal temperature, enhancing building health and reducing energy consumption. Used in many Green Star buildings in New Zealand, it promotes energy efficiency and sustainable building practices.

Project-specific condensation risk analysis determines the optimal components – vapor barrier, insulation thickness, and membranes – ensuring the correct R-values and condensation control while minimizing costs. While a project specific wind uplift calculation determines the optimal roof fixing method.


Soprasolar presents an innovative solution for installing solar panels on flat membrane roofs, catering to the increasing demand for sustainable energy solutions in New Zealand. Installing solar panels on flat roofs offers various advantages, including optimal angling and orientation, but the traditional installation process involves time and cost intensive methods.

Soprasolar’s solution offers a pedestal fitted with a piece of roofing membrane which is then welded directly on top of the finished roof waterproofing, eliminating the need for penetrations in the roof. Soprasolar ensures non-penetrative installation while offering cost-effectiveness, quick install, and reliability. Compatible with bitumen and TPO membrane roofs, this solution has been rigorously tested under high wind loads to ensure long-lasting durability.
