Standing Seam vs. Exposed Fastener: Choosing the Right Metal Roof for Your Project
May 30, 2025

When it comes to metal roofing, two of the most common panel types are standing seam and exposed fastener. Each option has its own strengths, price points, and best-use scenarios. Understanding the differences can help contractors and homeowners choose the right fit for their project.



At Platinum Metals, we manufacture both styles and support our customers in selecting the best solution for their budget, building type, and long-term goals.

🔒 Standing Seam Roofing Systems


What it is: A premium metal roofing option where the fasteners are hidden beneath interlocking vertical seams.


Key Benefits:

  • Clean, modern appearance
  • Superior weather-tightness (no exposed screw penetrations)
  • Longer lifespan with reduced maintenance
  • Allows for thermal movement, reducing potential for warping or oil canning


Best for: High-end residential, commercial buildings, or homeowners looking for a sleek, long-lasting roof with minimal maintenance.


Considerations:

  • Typically more expensive upfront
  • Requires more precise installation
  • Slower to install than exposed fastener systems


🔩 Exposed Fastener Roofing Systems


What it is: A traditional metal panel where screws are driven through the panel face and remain visible.


Key Benefits:

  • Cost-effective and budget-friendly
  • Faster installation
  • Strong performance when properly installed and maintained


Best for: Agricultural buildings, garages, pole barns, and cost-conscious residential or light commercial projects.


Considerations:

  • Screws are exposed to the elements, requiring more long-term maintenance
  • Shorter lifespan compared to standing seam
  • May be more prone to leaks over time if screws loosen or washers degrade


⚖️ Making the Right Choice


If you're weighing cost vs. longevity, or aesthetic vs. function, both panel types offer value depending on the project. Standing seam offers the highest performance and appearance, while exposed fastener systems provide speed and affordability.

No matter what you choose, Platinum Metals has the materials, resources, and support to help you install it with confidence.
