What Gerard Roofs does

Gerard Roofs (legal entity RoofTG Pacific Ltd) is a New Zealand-based manufacturer of stone-coated pressed steel roofing tiles, founded in 1957 by L.J. Fisher & Co and operated since 1968 from a single ~85,000 square foot manufacturing plant in Glen Innes, Auckland. The company produces two principal technology families: traditional pressed steel tile profiles (Shake, Milano, Senator, Classic, Bond, Antica) and the Concealed Fastening (CF) range (Calibre, CF Shake, CF Shingle, CF Slate), all built on a 0.55mm steel core with zinc-aluminium alloy protective coating and optional natural stone-chip overglaze. Proprietary design features include Concealed Fastening (hiding fasteners between interlocking panels), Above Sheathing Ventilation (ASV) head-pads providing approximately 2,000mm² of free vent area per tile, and a non-penetrating solar panel bracket system; the Calibre design has patents pending. The portfolio is complemented by accessories, Gerard Roof Coatings (paint), and MossBoss moss treatment.

Gerard generates revenue through one-time sales of roofing products and complementary accessories, distributed primarily through a network of qualified roofing contractors, Gerard Roofing Centre (GRC) branches, and regional distributors across New Zealand, with export representation in 127 countries including Tilcor (USA) and ACGM (New Caledonia). Customers include residential homeowners (re-roof and new build), trade professionals (roofing contractors, architects, developers via the 'Specifying with Gerard' program), and project segments such as retirement living, heritage restoration, hospitality resorts, and commercial attractions. Pricing is project-specific via a free-quote model; warranty terms extend up to 30 years for perforation and 20 years for surface coating. The company operates as a subsidiary of IKO (IKO Metals Asia Pacific), which is investing in a 2022-2027 expansion and renovation of the Glen Innes manufacturing site. Other product differentiators include verified wind resistance up to 350kph (James Cook University testing), Class A Fire Rating capability, ISO 14001 environmental management accreditation, and AS/NZS 4020 compliance for rainwater harvesting.

Recent moves6 records

Expansion highlights5 records

Regional players

• Eagle Roofing Products: Eagle Roofing manufactures concrete roof tiles for the US residential market. It targets the same new-construction and re-roofing use cases as Gerard but with a fundamentally different material (concrete vs. stone-coated steel) and is concentrated in North America.
• Roofing Industries: Roofing Industries is a New Zealand metal roofing manufacturer offering long-run and profiled metal roofing products. It competes with Gerard for NZ re-roofing and new-build specifications, though it focuses on long-run rather than stone-coated tile systems.

Direct peers

• Decra Roofing Systems: Decra manufactures stone-coated steel roofing tiles with interlocking panel systems for residential and commercial markets globally. It is the closest direct functional peer to Gerard, offering competing profiles (shake, shingle, tile) and warranties targeting the same re-roofing and architectural specification use cases.
• Metrotile: Metrotile produces pressed metal roof tiles with stone-chip coatings and concealed-fastening profiles across Europe, Asia, and Oceania. It competes head-to-head with Gerard on aesthetics, weight, and weather performance, particularly in coastal and high-wind markets.

Broad incumbents

• IKO: IKO is Gerard's parent conglomerate and a global manufacturer of roofing membranes, shingles, and insulation. While it owns Gerard, IKO's broader portfolio (asphalt shingles, commercial membranes) overlaps in customer and channel, and IKO's other metal roofing brands internationally compete with Gerard in export markets.
• Boral Roofing: Boral Roofing manufactures concrete and clay roof tiles alongside metal roofing systems across Australia, North America, and Asia. It overlaps with Gerard primarily in the Australian residential and commercial roofing specification market, though its product mix is broader and more commodity-weighted.
• Colorsteel (BlueScope Steel): Colorsteel, owned by BlueScope, is the dominant long-run metal roofing brand across New Zealand and Australia. It is not a direct stone-coated tile competitor but competes for the same roofing specification, with significantly broader distribution and lower price points.
• TAMKO Building Products: TAMKO manufactures asphalt shingles and metal roofing products primarily for the North American residential market. It is an indirect competitor via shared distribution channels and customer segments, particularly for homeowners comparing asphalt shingle versus stone-coated metal systems.
