A Brief Overview
The standing seam metal roof is a commonly used roofing system for residential homes, commercial establishments and in industrial properties. The name of roofing originates from the seam that forms when you lay the sheet metal panels side by side. The panels are then joined together at the seam by different methods.
Methods of Fastening In Standing Seam Metal Roof
Some use concealed fasteners; others use metal clamps that go over the seam, snap-on systems, lock and seam systems and so on. Here is a brief description of the most common methods used.
Field Locking System
When laying the metal panels, a unique locking tool is used to join the panels by forming a seam in the field. This is a commonly used fastening method in metal roofs.
In the snap lock system, when you place the adjoining metal panels side by side, one panel snaps onto the next locking it in place over the fasteners and clips. This hides the fastenings and clips from view.
Postive Locking Seam
With the positive locking system of the panels, there are no extra caps, strips or clips to install. One panel is hooked on to the next and joined by metal fasteners that go through pre-punched holes. The panels go over the fasteners concealing them.
Continuous Standing Seam
The lock and seam are an integral part of the panels, and no extra caps are needed. The standing seam metal roof panels can be prefabricated and shipped or bent on site or at sheet metal fabrication shops.
