If you're looking to install a new metal roof, the first step is knowing how to attach the panels. There are two main ways to do this: exposed fastener and concealed fastener systems. In this blog post, we'll go over the steps for both types of systems, so you can choose the best one for your needs. We'll also discuss the importance of tightening the screws correctly and show you how to do it the right way. Plus, we'll tell you what tools you need to get the job done!
What's the Difference Between an Exposed and Concealed Fastener System?
The first step in choosing the right fastener system is understanding the difference between exposed and concealed fasteners. Exposed fasteners are just what they sound like - the screws or nails that hold the panels in place are visible after installation. Concealed fasteners, on the other hand, are hidden from view.
There are a few benefits to choosing a concealed fastener system. First, they provide a more polished look since the screws are hidden. Second, they're less likely to leak since the screw heads are covered. However, exposed fastener systems are usually easier to install.
Now that you know the difference, let's move on to the installation process.

Concealed Fastener System:
A concealed fastener system is a bit more difficult to install, but it has a cleaner look since the screws are hidden.
You'll need the following tools to install a concealed fastener system:
Installation of a concealed fastener system is similar to an exposed fastener system, with a few key differences. The first is that you'll need to use a pneumatic or cordless drill, as the screw heads need to be countersunk into the metal. This means that you'll need to make pre-drilled holes, and then use a larger drill bit to enlarge the hole.
Another difference is that you'll need to install the screws at an angle. This helps the screw grip the metal better and prevents it from coming loose over time. Start by drilling a pilot hole and then angling the drill bit so it's at a 45-degree angle. Insert the screw and tighten it until it's snug.
Once you attach the panels to the furring strips with screws, make sure the screw heads are flush with the surface of the panel. Next, install the Z-bar flashing. This will help the water run off the roof. Finally, install the ridge cap. This will seal the edges of the roof and protect it from the elements.
Now that you know the basics of how to attach metal roof panels, you can start your project with confidence! Just remember to take your time, use the right tools, and follow the instructions for either an exposed or concealed fastener system. With a little bit of effort, you'll have a beautiful and long-lasting metal roof.
