Why Interlock
We’re here to raise the standard of New England roofing with lifetime aluminum systems and the Alunar® cool-roof coating.
Our work is guided by long-term thinking—creating spaces that perform reliably today and remain relevant, efficient, and sustainable over time.
Lifetime Aluminum Roofing
Four-way interlocking aluminum systems — slate, cedar, shake, Mediterranean tile, standing seam, and solid copper — engineered to never re-roof again, backed by a Lifetime Limited 50-Year Transferable Warranty.
Built for New England Weather
Coastal salt air, hurricane-force winds, Class IV hail, and the freeze-thaw and ice dams that destroy ordinary roofs — our aluminum sheds snow, never rusts, and lasts a lifetime.
