We know commercial roofing inside and out.
We focus on partnering with commercial construction companies to supply and install premium commercial roofing products from New Zealand’s leading suppliers.
Metal roofing (also known as long run roofing or good old fashioned corrugated iron) is widely used in commercial and industrial developments across New Zealand. It offers durability and weather resistance, making it suitable for various environments, including coastal and chemical industry areas. Metal roofing comes in various profiles, colours, and finishes, providing design flexibility for commercial buildings. We are approved installers of Dimond, Metalcraft, Roofing Industries, Steel & Tube, ColorCote, Colorsteel, Ampelite Skylights and Alsynite Skylights roofing products.
Membrane roofing is an excellent solution for flat roofs, low slope roofs, and even pitched roofs. It's also used for decking and gutters. Types of membrane roofing include single ply membrane, TPO and torch on. We are approved applicators of Ardex and Allco membrane products.
Insulated roof panels have steel panels with an insulating layer of foam in the middle. They offer superior thermal performance and fire rating while still being easy-to-fit and low maintenance. Well-insulated buildings offer long-term running cost savings as they help reduce the amount of energy used to heat, cool or maintain a comfortable indoor environment. We are approved installers of Kingspan and Conqueror insulated panel products.
Warm roof systems can boost efficiency, meet H1 compliance, and satisfy asset owners’ needs functionally and aesthetically. Practical and suitable for a range of roofing profiles, these systems can also be optimised for performance where you want it most, be it thermal, acoustic or appearance. In some instances, a warm roof solution can save time and resources during construction, expediting early close-in. We are approved installers of Dimond's Advanced Roofing Systems and Allco's Warm Roof System.
Overlay roofing makes it possible to use the existing roof substrate underneath it. This means buildings and the operations within them can remain functioning with minimal disruption while the building is re-roofed. And like all roofing solutions we offer, overlay roofing is designed and engineered for longevity and durability, weather tightness, as well as helping improve thermal and acoustic performance.
Our complete roofing solutions include how water gets off the roof and down the building. Not only are these systems essential for the longevity of the building, they’re necessary for compliance. They may also provide economic and sustainability benefits through the harvesting and reuse of rainwater within the building. We can also replace or repair spouting, downpipes, and flashing to ensure buildings are watertight and fully functional.
To provide safe access for workers carrying out building maintenance and repairs, we install height safety and roof access systems. We use products such as anchor points, static lines, walkway systems and more, from world leading suppliers because there’s no room for compromising on quality when it comes to safety. We are approved installers of Maxsafe Height Safety Equipment and Monkeytoe Roof Access Systems.
Regular maintenance is crucial for commercial roofs and is often a condition of warranties. We offer one-off repairs and maintenance services as well as scheduled asset maintenance to protect commercial roofs. Six-monthly inspections are recommended to stay ahead of New Zealand's weather conditions.
