Semple Gooder Roofing Corporation

What Semple Gooder Roofing Corporation does

Semple Gooder Roofing Corporation is a Toronto, Canada-based private construction contractor founded in 1947 that delivers building envelope services to commercial, institutional, and industrial clients. Its service offering spans roofing, cladding, maintenance, decking, and sheet metal work, positioning it as a multi-trade exterior envelope specialist rather than a single-product roofing installer. The firm employs between 101 and 250 people, which is consistent with a mid-sized regional contractor capable of running multiple concurrent project crews and supporting long-term maintenance contracts in the Greater Toronto Area and broader Ontario market.

The company's business model is project- and contract-based commercial construction services revenue, with monetization occurring through installation contracts for new construction and re-roofing, plus recurring maintenance and repair work on existing building envelopes. No pricing model, customer segmentation, channel mix, or specific technology stack is disclosed in the available source data, and the corporate website was inaccessible at the time of scraping (returning only a verification/loading page), limiting deeper extraction of go-to-market details, named customers, certifications, and supplier or union affiliations. The 78-year operating history is the primary indicator of operating continuity and embedded customer relationships in the Ontario commercial roofing trade.

Broad incumbents

• GAF: GAF is one of North America's largest roofing manufacturers and offers certified-installer contractor services. As an incumbent that competes for both material supply and project scopes, it is thematically adjacent to Semple Gooder's roofing business.
• Owens Corning: Owens Corning is a global building materials manufacturer with a major roofing shingles and components business. It competes indirectly with Semple Gooder through material supply and its contractor network, and is a relevant peer for benchmark pricing.
• Tremco Roofing: Tremco, part of RPM International, is a long-established roofing manufacturer and contracting services provider with broad North American reach. It competes with Semple Gooder on commercial reroofing and building-envelope work but is differentiated by its in-house materials portfolio.

Direct peers

• Baker Roofing Company: Baker Roofing is a multi-trade exterior contractor offering roofing, siding, sheet metal, and gutter services. It is highly comparable to Semple Gooder on the bundling of envelope trades under a single contractor model.
• Tecta America: Tecta America is a national commercial roofing contractor with installation, repair, and maintenance capabilities. It competes directly with Semple Gooder for institutional and commercial re-roofing contracts and offers a comparable full-service envelope model.
• Bone Dry Roofing: Bone Dry is a Midwest-based roofing and sheet metal contractor serving residential and commercial customers. It is comparable to Semple Gooder as a mid-sized, multi-service exterior contractor.
• Flynn Group (Flynn Canada): Flynn is the largest commercial roofing and cladding contractor in North America with a substantial Canadian operation out of Ontario. It is the most directly comparable peer to Semple Gooder, competing for the same GTA institutional re-roofing, cladding, and sheet metal scopes.
• CentiMark Corporation: CentiMark is one of the largest commercial roofing contractors in North America, offering roof installation, repair, maintenance, and sheet metal services. It mirrors Semple Gooder's service model across roofing and metalwork but operates at much greater scale across the U.S.
• Nations Roof: Nations Roof is a large U.S. commercial roofing contractor providing new construction, replacement, repair, and maintenance. Its service mix and customer profile closely align with Semple Gooder's commercial and institutional focus.

Others

• Sika Canada: Sika supplies roofing membranes, waterproofing, and sealing systems used on the same commercial envelope projects Semple Gooder delivers. As an enabling materials supplier rather than a direct installer, it is an adjacent ecosystem peer rather than a head-to-head competitor.
