A standing seam roof is a type of metal roofing system characterized by vertical or raised seams that run continuously from the ridge of the roof down to the eaves. The "seams" are created where two metal panels come together, and they are raised above the level of the roofing panel, which distinguishes them from flat or flush-mounted roofing types.

Key Features:

• Raised Seams: The seams typically stand between 1 to 2 inches above the roof surface.
• Hidden Fasteners: Unlike some metal roofs that expose fasteners, standing seam systems hide the fasteners beneath the panels, reducing the chance of leaks and offering a sleeker appearance.
• Durability: Often made from materials like galvanized steel, aluminum, or copper, these roofs are known for their durability and long life (typically lasting 30-50 years or more).
• Water Tightness: The design is effective at channeling water off the roof and minimizing the risk of leaks.
• Low Maintenance: They require minimal upkeep over time compared to other roofing materials.

Standing seam roofs are popular for both residential and commercial buildings, appreciated for their modern aesthetic, weather resistance, and energy efficiency (often reflecting solar heat, helping to keep buildings cooler).
