ROOF WATERPROOFING
Flat roofs, low-pitch designs, and architectural parapets require perfect execution. In New Zealand’s unpredictable climate, standard roofing materials often cannot handle the intense UV rays and heavy rain. At Sahara Waterproofing, we keep up to date with the latest international products, application methods, and membrane technologies to provide lasting, high-quality solutions that protect your investment.
​
Whether you need to permanently stop roof leaks in an existing commercial building or want a carefully designed system for a modern architectural home, we understand it’s crucial to get it right the first time. Repairing flat roofs can be expensive; our goal is to ensure you only pay for it once.

Tailored Membrane Systems for Every Substrate
No two roofs are alike. After a detailed on-site evaluation of your roof's pitch, substrate condition, and thermal performance needs, our Licensed Building Practitioners (LBPs) will create a custom roof waterproofing plan. Depending on the structural needs of your building, we use specialised single-layer or multi-layer configurations:
-
Single-Layer TPO Systems: Using high-quality Everguard TPO, these systems provide excellent UV resistance, heat-reflective properties, and strong welded seams. They are perfect for large commercial spaces and modern residential designs.
-
Multi-Layer Torch-On Bitumen: We focus on high-performance Nuralite and Ardex torch-on bitumen systems. These multi-layer setups deliver outstanding puncture resistance and long-lasting durability even in tough coastal conditions.
-
Insulated Warm Roof Systems: To meet modern NZBC H1 energy efficiency standards, we install fully insulated warm roof systems. By placing high-R-value insulation directly under the waterproofing membrane, we prevent thermal bridging, control internal condensation, and significantly reduce your heating and cooling costs.
The LBP Assurance
A leaking flat roof can compromise the structural integrity of your entire property. As approved applicators for New Zealand's leading membrane suppliers, our work complies fully with the NZ Building Code and is backed by our comprehensive 10-year workmanship guarantee.
