Watertight Systems

What Watertight Systems does

Watertight Systems Ltd is a specialist roofing and waterproofing contractor headquartered in Wanaka, New Zealand, serving the Southern Lakes region (Wanaka, Queenstown, and surrounding areas). Founded in 2006 by Andrew and Kate Bull, the company installs membrane roofing systems — torch-on bitumen, TPO single-ply, warm roof systems with PIR insulation, green roofs, and metal roofing/cladding/spouting — for residential and commercial projects, with a particular focus on architecturally designed luxury homes and complex alpine builds. Services also include below-ground waterproofing (tanking, underslab, retaining walls, drainage mats), membrane re-roofing overlays, and annual roof inspections starting at NZD $399 + GST.

The company operates a project-based professional services model with quote-based pricing determined by scope, membrane type, roof size, and complexity. Revenue is generated through fixed-price contracts delivered by in-house teams of waterproofing specialists, with the Wanaka office as the regional headquarters and a Queenstown/Frankton satellite office. Distribution is entirely direct: Watertight engages with architects from early design through construction and works alongside building companies on a project basis, supplemented by a referral-driven pipeline. The go-to-market emphasizes relationships with leading architects and building companies on complex, high-spec projects rather than volume-based residential work.

In 2024 the company expanded its product surface by forming Watertight Metal Ltd, a joint venture with metal-roofing specialist Brad Van Lierop, to deliver metal roofing, cladding, and spouting services. The business remains 100% New Zealand-owned, with no external institutional investors; ownership is concentrated among co-founders Kate and Andrew Bull and long-term team members including Operations Manager and shareholder Jannik Schroder. The firm maintains supplier relationships with leading membrane and material manufacturers (Allco, Equus, Nuralite, Ardex, Viking Roofspec) and is a Sitewise Gold member for site safety compliance.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Ardex New Zealand: Global manufacturer of waterproofing, tiling and flooring systems with a NZ operation. Provides membranes and sealing products Watertight uses, but operates as a much larger incumbent with broader product, training and installer-network reach than a regional specialist.
• Dimond Roofing: Established New Zealand metal roofing and cladding manufacturer with nationwide installer network. Competes with Watertight Metal for metal roofing projects while serving a much broader national footprint than the Southern Lakes-only operator.
• Fletcher Building / Fletcher Construction: New Zealand's largest construction and building products conglomerate. While not a roofing specialist, it controls national waterproofing and roofing contracting capacity through subsidiaries and could displace regional specialists like Watertight on large commercial projects.

Direct peers

• Equus Industries: NZ manufacturer of waterproofing membranes, coatings and tanking systems. Listed as Watertight supplier; also services commercial and residential projects with comparable membrane and below-ground waterproofing offerings, making it both a partner and a competitive installer network.
• Waterproofing Systems NZ: NZ-based specialist waterproofing contractor offering membrane roofing, tanking and below-ground services for residential and commercial projects. Operates in the same specialty contractor category as Watertight, with comparable product mix and architect/builder customer base.
• Viking Roofspec: Major New Zealand membrane systems supplier (Enviroclad TPO, Cover Board) that Watertight specifies and installs. Viking operates a certified installer network that competes directly with Watertight for TPO and warm roof projects across NZ.
• Roofing Industries (NZ): NZ manufacturer and supplier of metal roofing, cladding and roofing systems. Competes with Watertight Metal Ltd in the metal roofing/category in Southern Lakes and serves many of the same architects and building companies.
• Allco Waterproofing Solutions: New Zealand waterproofing systems provider (membranes, coatings, tanking) supplying Watertight and competing for the same commercial and residential membrane roofing and waterproofing contracts nationwide.
• Nuralite Waterproofing Solutions: NZ-based waterproofing membrane manufacturer and installer that supplies tanking and roofing membrane systems. Listed as a Watertight supplier, but also competes as a waterproofing specialist contractor across New Zealand on similar membrane roofing and below-ground tanking projects.

Regional players

• Apex Waterproofing: Specialist waterproofing contractor focused on Auckland and upper North Island. Comparable service offering in membrane roofing and below-ground tanking, but a different regional geography that limits direct overlap with Watertight's Southern Lakes territory.
