Metal roofing systems, such as flat seam roofs and standing seam roofs, are widely used in residential, commercial, and architectural applications. While they have similar materials and durability, their construction, look, and applications vary significantly.
What Are Flat Seam Roofs?
Flat seam roofs are constructed from individual metal panels laid flat and linked together at the edges with folding seams. These seams are usually low-profile and run in many directions, resulting in a smooth, unobtrusive pattern on the roof surface. Flat seam roofs are often used on roofs with a low slope or a gentle pitch.
They are also used on historic buildings, modern architecture, and custom-built homes. Because the panels are smaller and hand-seamed, installation is more detailed, allowing for intricate roof designs, curves, and transitions. Regarding water management, a flat seam roof’s tightly folded seams and precise detailing are ideal for moving water off the roof, particularly on low slopes.
What Are Standing Seam Roofs?
A standing seam roof consists of long, continuous metal panels that stretch vertically from the roof’s ridge to the eaves. The elevated seams are the distinguishing feature, rising above the panels’ smooth surface and running parallel to one another.
These seams are usually consistent and evenly spaced, giving the roof a linear, structural look. They also help move water off the roof, and depending on the technology, they are often mechanically seamed or snapped together. Standing seam systems are often used on steeper slopes in both residential and commercial construction, providing a more obvious, rhythmic pattern than flat seam roofs.
