Standing Seam Metal Roof - A Brief Overview |
Posted: January 16, 2018 |
The standing seam metal roof is a commonly used roofing system for residential homes, commercial establishments and in industrial units. The name of roofing originates in the seam that forms when the sheet metal panels are laid 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 fasterners, others use metal clamps that go over the seam, snap on systems, lock and seam systems and so on. Field Locking System When laying the metal panels, a special 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.
Snap Lock In the snap lock system, when the adjoining metal panels are placed side by side, one panel snaps onto the next locking it into place over the fasterners and clips. This way the fastenings and clips are hidden 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 fastners that go throught pre-punched holes. The panels go over the fasteners concealing them.
Continuous Standing Seam The lock and seam are integral part of the panels and no extra caps are needed. The Metal Standing Seam Roofs panels can be prefabricated and shipped or bent on site or at sheet metal fabrication shops. Pitch Requirement For Metal Roofs With Continuous Standing Seam The standing seam metal roofs are usually used for sloping roofs where a pitch is evident. Metal roofs can be installed even for small pitch difference. These metals roofs have been installed for a pitch of 2:12. So, it is not at all tough to have metal roofs for even small sloping roofs.
