About
HPM Building Supply is Hawaii Island's established building materials provider, manufacturing custom metal roofing panels directly from its Hilo facility — a meaningful advantage for commercial property managers and facility teams facing the Big Island's relentless salt air, high rainfall, and hurricane-force wind exposure. As a 100% employee-owned company with deep roots across the Hawaiian Islands, HPM produces metal roofing as part of a vertically integrated manufacturing operation that also includes wall panels, trusses, and pre-hung doors, making it a consolidated resource for commercial construction and re-roofing projects on Hawaii Island. For facility managers overseeing retail centers, industrial buildings, warehouses, and multifamily properties in Hilo and surrounding areas, custom-fabricated metal roofing offers critical durability advantages over membrane systems in Hawaii's coastal environment — resistance to moisture-driven corrosion, superior wind uplift performance, and long service life that reduces lifecycle replacement costs. HPM's manufacturing capability means panels can be produced to project-specific dimensions, reducing on-site waste and installation complexity for low-slope and steep commercial roof assemblies alike. While HPM's primary business model centers on supplying materials rather than performing roofing installation services directly, their product line supports contractors executing metal roof systems on office buildings, light industrial facilities, and mixed-use commercial projects throughout East Hawaii. Property managers coordinating roof replacements or new construction on Hawaii Island benefit from sourcing locally manufactured metal panels rather than waiting on mainland freight — a practical advantage given the island's supply chain constraints. Commercial teams evaluating roofing system options for corrosive coastal environments will find HPM's custom metal roofing production a regionally relevant, logistics-efficient component of any commercial re-roofing or new construction program on the Big Island.
