1. Screw-Fastening Method
The screw-fastening method is the most commonly used method for fastening metal roofs. It involves using hex head screws fitted with rubber washers drilled into the metal roofing and then into the roof deck beneath. Overall, the screw-fastening method is a reliable and cost-effective method for those seeking to install a metal roof.
2. Clip-Fastening Method
Clips are attached to the metal roof panels. The panels are then attached to the roof deck using screws. The advantage of this method is that it accommodates the natural expansion and contraction of the metal panels due to temperature changes.
3. Hidden-Fastening Method
The hidden-fastening method is an innovative way to fasten metal panels to the roof deck without exposing screws or clips. The technique involves using standing seam roofing systems where the seams of the metal panels are raised and then attached to the roof deck using clips. This method creates a sleek, clean look that is ideal for high-end residential and commercial roofing applications.

However, they all have one common goal—ensuring the metal roof is securely fastened and leak-free.
