We specialize in custom copper design, fabrication, and installation, including standing seam and flattened seam roofing, bay roofs, built-in gutters, flashing, and architectural details executed with time-tested techniques and modern precision for lasting performance and enduring quality.
Copper is one of the most durable, visually striking, and high‑value exterior upgrades a home can receive. At Group Three Construction, we combine traditional artisan copper craftsmanship with modern installation techniques to deliver copper roofs, flashing systems, and architectural copper details built to last for generations.
For decades, we have specialized in handcrafted copper roofing, expertly combining traditional metalwork techniques with modern fabrication standards. We custom design, fabricate, and install copper roof panels, built in gutters, custom detailing, chimney and roof flashing. We install complete copper gutter systems that deliver both beauty and structural protection. Copper resists corrosion and weather while naturally developing its signature patina, giving each home a distinctive character that grows more refined over time.
Every detail of our copper roofing, detailing, and architectural copper work is fabricated and installed according to Copper Development Association (CDA) design standards. This ensures watertight performance, structural integrity, and long-term durability. Our specialists are skilled in precision fabrication, seam soldering, advanced flashing integration, and custom copper detailing for chimneys, bays, porches, built in gutters and entryways.
From built-in copper gutters to handcrafted detailing and complete roof systems, we approach each project with an artisan mindset, delivering installations that are as exquisite as they are functional. We also provide expert copper roof repairs, patina application, leak detection, and upgrades to older systems. Whether enhancing curb appeal with a custom detail or protecting your home with a full copper roof, our craftsmanship ensures advanced knowledge, technical excellence, and lasting performance.

Copper is a premium roofing material that requires advanced craftsmanship and years of experience to install properly, which contributes to its higher upfront cost. Like slate, copper offers exceptional longevity and one of the strongest returns on investment, often lasting the life of the structure with minimal maintenance.
Copper roofs often last 70–100+ years with minimal maintenance, making them one of the longest-lasting roofing materials available.
Copper expands and contracts with temperature changes. Proper installation requires specialized fastening methods, appropriate panel sizing, and the use of expansion joints to allow for this movement. When copper is carefully detailed to accommodate thermal expansion, it performs reliably for decades; when movement is restricted, premature failure can occur.
Yes, we are experts at hand soldering. All our designs, locking and soldering techniques are in accordance with The Copper Development Association and Copper & Common Sense.
Patina solutions are available in several formulations and are used to accelerate copper’s natural oxidation process, allowing it to develop color more quickly. We typically use them when matching new copper work to existing sections that have already progressed in the patina process, ensuring a more uniform and cohesive appearance.
Galvanic corrosion occurs when dissimilar metals come into contact in the presence of moisture, creating an electrical reaction that causes the less noble metal to deteriorate. In roofing assemblies that use multiple metals, careful detailing and separation are essential to prevent contact, avoid accelerated corrosion, and ensure long-term performance.
