Membrane and Warm Roof Solutions Designed for Low Pitch Roofing

Low pitch and near flat roofs demand more from a roofing system. Reduced falls place greater pressure on drainage, weathertightness, insulation continuity, and long term durability. For architects and designers, the solution lies in choosing membrane and warm roof systems designed specifically to overcome these challenges.

Equus offers a suite of two-layer bitumen and TPO membrane systems, along with proven warm roof build ups, that deliver reliable performance where roof falls are minimal. These systems combine certified product assurance with the design support needed to simplify low pitch roofing.

Engineered weathertightness for low falls

At low pitch, the waterproofing layer must withstand slow drainage, increased UV exposure, and more complex detailing. Equus Soprema two layer bitumen membrane systems, such as the DUO membrane, offer a durable, fully bonded waterproofing solution that performs exceptionally well where falls are minimal. CodeMark certified to 1:80 falls, the system supports low pitch design without compromising compliance or durability.

Equus TPO membranes offer a lightweight, heat welded option with excellent dimensional stability and resistance to ponding. Their clean, fast installation makes them well suited to large commercial and multi unit roofs where falls are limited and detailing efficiency is essential.

Both membrane types are BRANZ Appraised, giving confidence in long term performance when designing at low pitch.

Warm roofs: Solving insulation and condensation risk

Warm roof systems provide a critical advantage for low pitch roofing: continuous insulation above the structure, eliminating thermal bridges and creating predictable thermal performance. For near flat roofs with limited ventilation, this reduces condensation risk and helps meet NZBC H1 energy efficiency requirements.

Warm roofs also simplify many difficult junctions — particularly parapets, gutters, transitions and penetrations — creating more reliable detailing outcomes.

Designed for performance, backed by support

Equus supports each project with technical design assistance, system detailing, BRANZ Appraisals, CodeMark certification, and full QA documentation. This ensures membrane and warm roof systems not only meet NZBC E2, B2 and H1 requirements, but are applied correctly in practice.

For architects designing low pitch roofs, Equus provides both the proven systems and expert support needed to deliver durable, compliant, and high performing roof solutions.
