Choosing the right metal roofing system can be confusing—especially when it comes to exposed and non-exposed fastener systems. At Top Shield Roofing Systems, we help you understand the difference so you can pick the best roofing solution for your property.
What Are Exposed Fastener Systems?
Visible Screws and Simplicity
Exposed fastener systems, like R-Panel or corrugated metal roofing, feature visible screws that fasten the metal panels directly to the structure. You can literally see the screws on the surface.
Pros
-
Affordable – Fewer materials, faster installation
-
Quick to install – Ideal for large projects
-
Strong performance – Holds well in rough weather
Cons
-
Screws may loosen over time
-
More frequent maintenance to check for leaks
-
Less sleek appearance compared to hidden systems
What Are Non-Exposed Fastener Systems?
Hidden Screws for a Clean Look
Non-exposed systems—like standing seam roofs—have concealed fasteners hidden under the panels or clips. That gives them a clean, modern appearance and better long-term durability.
Pros
-
Sleek finish – Great for modern homes and commercial buildings
-
Lower risk of leaks – Screws protected from the elements
-
Longer lifespan with less maintenance
Cons
-
Higher cost – Due to complex installation and material
-
Takes more time to install properly
