Benefits of Metal Roofing Screws

Originally many years ago metal panels were attached to post-frame structures with nails. This eventually changed to nails with washers to provide some degree of weather tightness. As installers looked to improve both the holding power and weather tightness of the attachment, threaded fasteners with sealing washers were developed specifically for the panel to wood applications. Over the years, the designs have improved to maximize the benefits - ease, and speed of installation, holding power, pullout values, and corrosion resistance. The holding power or pullout strength of screws is substantially higher than any nails. Additionally, screws can be easily backed out if the need arises, a task not so simple with nails.

What are metal roofing screws made of?

The metal screws are made of different types of metals to achieve different results. Each metal screw type is ideal for certain types of projects. The standard screws might be a steel base with a coating to provide some level of corrosion resistance. To ensure more protection against corrosion, stainless steel screws are ideal for aluminum panel attachment. If you are looking for wood-to-metal screws, you need to look for ones that have a head and shank that are made with a solid metal that will allow the fastener to penetrate wood substrates.

Metal to Metal Screws

Metal-to-Metal screws are available in different diameters and lengths. These metal roof screws are designed to fasten metal roof panels to structural metal. These fasteners have self-drilling tips that fasten quickly and easily. The attached washers create a tight seal with the metal roof to prevent moisture and other corrosive elements from damaging the screw shank and leaking into the structure.

Choosing The Correct Fastener For Exposed And Concealed Panel Systems

The type of fastener you use depends on whether you are installing exposed fastener panels or concealed fastener panels. Wavy corrugated and R Panel are examples of exposed fastener panels. Standing seam or flush wall panels are concealed fastener panels. When installing exposed fastener panels, fasteners with rubber sealing washers are used to increase the weather tightness of the panels and keep water out.
