Metal roofs

There are many materials to choose from when opting for a sheet metal roof. Aluminum, copper, steel and numerous other metals are used for building highly durable roofs. They have a long useful life, they’re sturdy and resilient and, above all, they’re energy efficient. There are also a multitude of metal roof styles: vertical metal panels, corrugated and ribbed, interlocking metal shingles, and stone-coated steel tiles. A sheet-metal or other metal roof is the perfect solution for any climate. Snow, ice, freezing rain, hail, sunshine: a metal roof, when installed by the seasoned professionals at Groupe Pentagone, can last as long as a century.
