Interlock Expands to Aluminum Siding for Unified Exteriors

Interlock Roofing Ltd., a leader in lifetime aluminum roofing systems, has expanded its product line with the launch of Interlock Metal Siding and aluminum wall cladding. The new panels are crafted from the same heavy-gauge aluminum as their roofing products and finished with the proprietary Alunar Coating System, allowing homeowners to achieve a cohesive, color-matched exterior from roof to foundation. This integration addresses compatibility issues often encountered when using products from different manufacturers, simplifying installation and unifying warranty coverage across all exterior surfaces. The debut installations include custom homes in Whistler, British Columbia, showcasing the system's versatility and aesthetic appeal.

The Interlock Metal Siding line features four architectural profiles—Slate, Cedar Shingle, Shake, and Standing Seam—which can be mixed within the same color family for customized designs. Engineered for durability, the panels are non-combustible with a Class A fire rating, making them suitable for wildfire-prone regions. The aluminum core resists moisture, preventing rot, warp, and crack damage from freeze-thaw cycles, while the factory-baked Alunar coating resists chalking and fading, eliminating the need for repainting. Additionally, the material is resistant to insects and coastal salt-air corrosion, and it is approximately 95 percent recyclable at end of life, aligning with sustainable building practices. Four-way interlocking panels install over most existing substrates, and certified installers ensure a seamless fit without the need for ongoing maintenance like painting or sealing.

Available across the United States and Canada, Interlock's aluminum metal siding and wall cladding system extends the company's lifetime warranty to the entire building envelope. Scott Plumptree, Director of Marketing, emphasized that homeowners who trust Interlock's roofing can now apply the same performance and design standards to their siding. The product line is supported by a Lifetime Limited, 50-year transferable warranty, providing long-term value and peace of mind. For more information, visit interlockroofing.com/siding.
