Custom Copper Roofing: Timeless Craftsmanship That Ages Beau

Custom copper roofing stands as one of the most luxurious and enduring choices available—fabricated from high-purity sheet copper that we form, seam, and install entirely on-site for a perfect fit on any roofline, bay, dormer, or accent. Whether standing seam panels for expansive slopes, flat-seam soldering for intricate bays and turrets, or decorative diamond patterns, copper delivers a brilliant shine when new that gradually transforms into a rich brown and finally the iconic verdigris patina—a natural protective layer that seals the metal against corrosion for centuries.

Copper roofs last 100 years or more with virtually no maintenance, resisting fire, hail, high winds, and Ontario's freeze-thaw cycles far better than steel or aluminum alternatives. The material expands and contracts gracefully without cracking seams, sheds snow effortlessly, and adds undeniable curb appeal that increases property value.

As custom metal specialists, we've learned exactly where copper installations fail when done poorly: seams open from improper cleating or thermal movement, flashings lift at chimneys and walls due to lightweight gauge or poor integration, pans buckle on low-slope bays without adequate substrate support, and eaves corrode prematurely if drainage isn't perfect. These issues almost always trace back to off-the-shelf panels or rushed fabrication—problems we eliminate from the start.

At Alexander Slate, we are the premier choice for custom copper work because we treat it as an art form, not an assembly line. Every project begins with precise measurements and templates; we use only 16–20 oz cold-rolled copper, hand-folded standing or flat-lock seams, and hidden cleats that allow unrestricted movement. Our crews fabricate on-site for seamless transitions around curves, dormers, and penetrations—no pre-made panels that force compromises. We integrate copper gutters, finials, and snow guards as part of the system, ensuring water flows exactly where it should.

Why are we the best? We know copper's secrets from restoring historic Toronto mansions and installing new masterpieces across the GTA and Ontario. We're more expensive because we refuse shortcuts: no thinner gauge that dents easily, no exposed fasteners that leak, no generic designs. Clients choose us for roofs that start stunning and grow more beautiful with age—quiet through blizzards, cool in summer, and warrantied against callbacks.

Whether a full standing seam copper roof, custom bay window caps, ornate dormers, or targeted chimney and wall flashing upgrades, Alexander Slate delivers heirloom-quality work built to outlast the building itself.
