Earth Day and Your Roof: The Real Sustainability Case for Metal
Earth Day began in 1970, sparked by a 1969 oil spill off Santa Barbara, and is now the world’s largest secular observance, marked by more than a billion people. Beyond the history, going green can save real money — and a recyclable, energy-efficient metal roof is one of the most durable green choices a homeowner can make.

What Is Cool Roofing? CRRC Ratings & Benefits
A “cool roof” reflects the sun’s heat instead of absorbing it, lowering cooling bills and indoor temperatures. Interlock’s energy-efficient Alunar® finish reflects up to 55% of solar energy (reflectance 0.25–0.55) with a high 0.84 thermal emittance — and it works in any color, not just white.

Installing Solar Panels on an Interlock Metal Roof
An Interlock metal roof is an ideal base for solar: it lasts 40–70+ years (far longer than a 25–30 year array), so you never remove panels to re-roof. Standing Seam lets panels clamp on with no roof penetrations, the install doesn’t void the warranty, and the reflective surface keeps panels cooler and more efficient.

Investing in a Sustainable Future
A truly sustainable roof does two jobs: it lasts so long it’s rarely replaced, and it helps power the home. Interlock pairs a 95%-recyclable aluminum roof — made largely from recycled stock and installable over your old roof — with solar readiness, for decades of clean energy on a roof that outlives the panels.
