Membrane Roofing

Membrane roofing is a high-performance waterproofing solution ideal for flat and low-pitched roofs. It provides a seamless, weather-resistant barrier that protects against water ingress, UV exposure, and environmental wear—while also delivering a clean, modern look that complements a wide range of architectural styles.

We specialise in the installation of leading membrane systems, such as:

  • TPO (Thermoplastic Polyolefin): A durable, energy-efficient membrane known for its sleek appearance, heat-reflective properties, and long-term performance. TPO offers a crisp, uniform finish that enhances both residential and commercial rooflines.

  • Torch-On Membrane: A robust, bitumen-based system applied using controlled heat. It creates a strong, smooth surface that not only performs under extreme conditions but also maintains a neat, low-profile finish ideal for contemporary builds.

  • Butynol/EPDM: A flexible synthetic rubber membrane that adapts well to complex roof shapes and detailing. Its smooth, matte finish provides a refined, architectural aesthetic, making it a popular choice for design-focused projects.

  • PVC/KEE: A premium-grade membrane engineered for superior chemical, UV, and puncture resistance. PVC/KEE systems are reinforced with a high-performance polymer blend that maintains flexibility and strength even in harsh conditions. Their dimensional stability and exceptional lifespan make them ideal for demanding commercial applications or architecturally exposed flat roofs where performance and appearance go hand in hand.

Each membrane type offers a balance of durability, functionality, and visual appeal—ensuring long-lasting protection and a clean, professional finish for your home or building.

Shingle/Slate Roofing

We supply and install both asphalt shingle and natural slate roofing—two highly reliable options for pitched roofs that deliver strong performance and visual appeal.

  • Asphalt Shingle Roofing: We recommend asphalt shingles as a practical, cost-effective solution for many residential roofing projects. Easy to install and lightweight, shingles are a great fit for both new builds and re-roofing work. They handle wind, rain, and sun well, and with a range of colours and profiles available, we can help you achieve the right look for your home—whether it's a modern finish or something more traditional. Their low maintenance makes them a popular choice for homeowners wanting long-term reliability without ongoing upkeep.

  • Slate Roofing: For clients seeking a premium, timeless roof with real architectural character, we offer expert installation of natural and alternative slate. Slate roofing is incredibly durable—resistant to fire, mould, and harsh weather—and can last over a century with the right care. It’s ideal for heritage homes or high-end designs where quality and longevity are key. While slate requires skilled installation, our team has the experience and attention to detail needed to ensure a precise and lasting result.

Whether you're after a practical, low-maintenance roof or a statement finish that adds long-term value, we’ll guide you through the right choice and deliver a high-quality, professional installation.

Warm Roofing

We supply and install warm roof systems designed to improve energy efficiency, reduce condensation, and extend the life of your roof. A warm roof places the insulation above the structural deck, creating a continuous thermal barrier that keeps the building warmer in winter and cooler in summer.

Warm roofs are becoming increasingly popular in both residential and commercial construction for their performance and long-term value. By eliminating thermal bridging and reducing the risk of internal condensation, they help create a healthier, more energy-efficient environment.

Our team works with high-quality membrane and insulation products to deliver warm roof systems that are watertight, code-compliant, and built to last. Whether you're undertaking a new build or re-roofing project, we ensure your warm roof is installed correctly, with full attention to detail and long-term performance.

We’re proud to have worked on the largest warm roof project in New Zealand—a testament to our capability, workmanship, and trusted reputation in the industry. From large-scale commercial developments to architecturally designed homes, we bring the same level of expertise, precision, and commitment to every warm roof installation.

Grouting and sealants

We provide specialised services that support the structural integrity and weatherproofing of concrete buildings and infrastructure. Our team works with precision and care to ensure every detail is sealed, filled, and finished to a high standard.

  • Grouting & Dry Packing: We carry out both fluid grouting and dry packing depending on the requirements of the project. From Drossbach duct grouting in post-tensioned systems to dry packing under precast panels or base plates, we use high-strength, non-shrink materials and proven methods to ensure solid compaction, full coverage, and reliable structural performance.

  • Precast Panel Joint Sealant: We install flexible sealants in precast panel joints to prevent water ingress, accommodate movement, and protect the structure over time. Using high-quality, weather-resistant products, we ensure a clean, durable finish suitable for both internal and external applications.

Whether it’s a new commercial build or infrastructure project, we deliver consistent, high-quality workmanship that meets spec and stands the test of time.

Tanking

We install high-quality tanking systems to protect below-ground areas from water ingress and long-term moisture damage. Whether for basements, retaining walls, or under-slab applications, we match the right waterproofing product to the needs of your project.

We work with a range of proven tanking systems, including:

  • Liquid-Applied Membranes: These flexible coatings are applied directly to surfaces and form a seamless, fully bonded barrier. Ideal for complex shapes and tight spaces, liquid systems are fast to apply and cure into a durable, watertight layer.

  • Peel-and-Stick Membranes: These self-adhesive sheets offer consistent thickness and quick installation. They’re perfect for under slabs and retaining walls, providing strong adhesion and reliable moisture protection.

  • Torch-On Membranes: Heat-applied bitumen membranes that bond tightly to concrete surfaces. Torch-on systems are extremely robust and well-suited for areas needing long-term resistance to pressure and groundwater.

We’ll assess your site conditions and recommend the most effective system for lasting waterproofing and code compliance. Our team ensures each install is done right.
