Exposed fastener metal roofing is a popular choice for residential, commercial, and agricultural buildings due to its affordability and straightforward installation. As the name suggests, this roofing system features visible fasteners that secure the metal panels to the roof deck. While economical, it offers durability and a classic appearance, making it an excellent choice for various applications.
What is Exposed Fastener Roofing?
Exposed fastener roofing consists of metal panels attached to the roof deck with screws or nails that remain visible on the surface. These panels typically overlap, creating a watertight seal. The fasteners are fitted with rubber gaskets or washers to prevent water infiltration, ensuring durability and weather resistance.
This roofing system is often used for projects requiring practicality, such as barns, garages, and industrial structures, but it is also found in residential applications.

Installation Process

- Monitor Seams and Edges:
- Inspect overlaps and edge treatments for signs of wear or separation, sealing any gaps as needed.
Challenges of Exposed Fastener Roofing
- Fastener Maintenance:
- Over time, fasteners may loosen due to thermal expansion and contraction, requiring periodic tightening or replacement.
- Potential for Leaks:
- Improper installation or damaged washers can lead to water infiltration. Regular inspections are essential.
- Less Refined Appearance:
- The visible fasteners create a utilitarian look that may not suit every architectural style.
