Interlock Roofing

What Interlock Roofing does

Interlock Roofing is a family-owned North American manufacturer of premium interlocking aluminum metal roofing systems, founded in 1998 and operated through its parent I.E.L. Manufacturing Ltd. (Delta, Canada). The company designs and factory-produces heavy-gauge aluminum panels in five architectural profiles — Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam — together with an optional solid copper upgrade and adjacent metal siding. Its core technology is a four-way interlocking panel system paired with a proprietary Alunar® coating: a 70% PVDF coil-coat finish with IR-reflective ceramic pigments applied to both sides of every panel. The system is validated by UL 2218 Class 4 impact resistance, ICC-ES ESR-1790, Florida Product Approval FL7263-R7, CRRC cool-roof ratings, and a transferable 50-year limited warranty (Guardian Warranty).

The company sells direct-to-consumer to individual homeowners, generating leads through its website, toll-free contact, and home-show participation, then converting via free, no-obligation quotes from certified local installers. Installation is performed by a certified installer network spanning 14,050 service areas across the United States and Canada, supported by three wholly-owned regional subsidiaries (Alberta, New England, Maritime Canada). The company has completed 100,000+ installations since 1998, holds a 4.6-star rating across 8,799 verified reviews, and has accumulated 21M+ YouTube views as part of a content-driven lead-generation strategy. Revenue is generated through one-time sale of custom-manufactured roofing systems, with financing available in most regions; metal siding and solar-integrated roofing (clamp-on racking with zero roof penetrations) extend the revenue model into adjacent exterior-envelope categories.
