Signal & Hobbs - Roofing & Cladding Contractors

What Signal & Hobbs - Roofing & Cladding Contractors does

Signal & Hobbs is a Melbourne-based specialist metal roofing and cladding subcontractor that has operated continuously in Victoria since being founded in the 1970s by Peter Signal and Ivan Hobbs. The company installs Colorbond steel, Kingspan insulated panels, Lysaght products, stainless steel, and custom-fabricated sheet metal roofing systems for commercial, government, industrial, and multi-residential projects, engaging national Tier 1 contractors such as Kane Constructions, Hansen Yuncken, and ADCO Constructions through tender and direct-relationship processes. Its service stack spans expert estimating and quantity take-off, procurement and project management, in-house manufacturing of custom flashings and architectural sheet metal through sister company Roofing & Sheetmetal Centre, installation, and post-completion roof maintenance via SH Roof Maintenance, all delivered under ISO 9001:2015 and ISO 45001:2018 certifications by a 150+ headcount group.

The company operates as the foundation brand of the Sighob Group, a corporate structure introduced in 2024 that brought together Signal & Hobbs, Roofing & Sheetmetal Centre, SH Roof Maintenance, and Zinc Cladding. Revenue is generated on a project-by-project basis through fixed-price and cost-plus subcontracts with general contractors and direct clients, with pricing negotiated per tender rather than published. Repeat work with Tier 1 builders, an in-house apprentice program, and dedicated estimating and safety functions are the principal operating assets, and the customer base spans landmark projects including the Queenscliff Ferry Terminal ($16m), Whitehorse Performing Arts Centre ($56m), Peter McCallum Cancer Centre, Warrnambool Base Hospital, and Jubilee Park Indoor Stadium, with all operations currently concentrated in Victoria, Australia.

Direct peers

• Fielders Steel Roofing: BlueScope-owned commercial and architectural steel roofing brand offering comparable roll-formed roofing and cladding products to the Australian market. Direct product comparability with Signal & Hobbs' core metal roofing and cladding offering.
• Lysaght: BlueScope-owned steel roofing and cladding brand that supplies Signal & Hobbs' core materials and competes in the same commercial roofing category. Comparable product offering, target market (Australian commercial construction), and technology platform (roll-formed steel roofing systems).
• Stramit Building Products: BlueScope-owned Australian manufacturer of steel roofing, cladding, rainwater and structural products. Operates in the same commercial roofing materials category as Signal & Hobbs' core business and serves overlapping Tier 1 contractor and builder customers.

Broad incumbents

• CSR Limited: Australian building products group whose portfolio includes roofing, insulation and cladding systems. Comparable target market (Australian commercial and residential construction) and broad category overlap, though CSR operates as a manufacturer rather than installation contractor.
• Kingspan Group: Global manufacturer of insulated roof and wall panels that Signal & Hobbs specifies and installs. Operates an Australian business in the same insulated-panel and standing-seam category that Signal & Hobbs services, though at the manufacturer/integrator layer.
• BlueScope Steel: Australia's largest steel manufacturer and parent of Lysaght, Fielders and Stramit — the Colorbond and Zincalume brands Signal & Hobbs installs. BlueScope is a broad incumbent operating across the same roofing materials category though at the manufacturer rather than contractor layer.
• Boral Limited: Major Australian building products and construction materials company with overlapping customer base in commercial construction. While not a roofing specialist, Boral serves many of the same Tier 1 contractors and government clients across adjacent product categories.

Regional players

• Fletcher Building: New Zealand-headquartered building products and construction company with Australian operations. Operates in adjacent roofing, insulation and cladding categories in the trans-Tasman market — comparable offerings but primarily serving New Zealand rather than the Victorian geography where Signal & Hobbs is concentrated.
