Straight answers, up front

A premium aluminum interlocking roof is a lifetime investment priced above asphalt but with no replacement cost over the home's life. Exact pricing depends on roof size, pitch, and profile (shingle, slate, shake, standing seam, or copper). Request a free quote for a fixed, transparent estimate — no high-pressure sales.

No. Aluminum does not rust — it forms a stable oxide layer that protects it, which is why it outperforms steel in coastal and high-humidity New England environments. This is a core reason Interlock builds in aluminum rather than coated steel.

An Interlock aluminum roof is engineered to be a lifetime roof — "never re-roof again." We have documented New England installations still performing at 18+ years with no degradation, backed by a Lifetime Limited 50-Year Transferable Warranty. Aluminum does not rust, rot, or absorb water, so it outlasts asphalt (15-20 yrs) by decades.

Yes. Every Interlock aluminum system is solar compatible. Because the roof lasts a lifetime, you never have to remove panels to replace the roof beneath them — unlike asphalt, which must be re-roofed every 15-20 years, forcing costly panel removal and reinstallation.

Yes, with an honest caveat. Ice dams are caused by heat escaping into the attic — insulation, air-sealing, and soffit-to-ridge ventilation are what stop them forming, on any roof. What an Interlock roof changes is the damage path: the smooth interlocked surface sheds snow that would otherwise feed a dam, and with no exposed lap seams there is no joint for backed-up meltwater to leak through into ceilings and walls. We assess attic ventilation as part of every estimate.

For New England homes, aluminum resists salt-air and coastal corrosion better than steel and never rusts, while staying lightweight. Interlock's aluminum interlocking shingles carry a Lifetime Limited 50-Year Transferable Warranty and ~95% recycled content — an advantage over stone-coated steel systems in wet, coastal, and freeze-thaw climates.
