Concealed-fastener vertical panels — modern lines, serious snow shedding.

Modern lines, built for snow country

Standing seam has become the signature of New England’s modern farmhouses, coastal contemporaries, and clean-lined additions. Its long vertical panels and concealed fasteners give a crisp, architectural look — and on steep or simple rooflines they shed snow exceptionally well, a real advantage across Vermont, New Hampshire, and Maine.

Lifetime aluminum, not coated steel

Interlock builds standing seam in rust-proof aluminum, so coastal salt air and humidity won’t undercut the finish the way they can with steel panels. It’s solar-ready for the roof’s entire life, rated Class A fire and UL 2218 Class 4 hail, and protected by a Lifetime Limited 50-Year Transferable Warranty — modern looks that last a lifetime.
