The most widely used, traditional metal roof system, the mechanical lock, also commonly referred to as just standing seam roof, can be installed as a single lock or double lock system. This profile panel is available in 1” or 1.5” high standing seam. The double lock has long been considered the best locking system available and is it not uncommon to find century old systems still functioning properly. Commonly used materials are copper, lead coated copper, freedom gray, zinc, and Kynar coated steel and aluminum.
Copper based systems offer the advantage of being able to be soldered where needed, where aluminum systems are easier to work with and more malleable, while Kynar steel systems are a more tough panel, although not recommended for installations near the ocean.
These panels are secured to the roof deck via roof clips and can be curved. Other Colors and curved & tapered panels available by custom quote please contact us at [email protected] if you would like to place a custom order.
What is the difference between a single lock and a double lock roof panel?
They are both the same panel, known as simply a standing seam panel, or a mechanical lock panel. One side of the panel has the male lock while the other has the female lock. To put these panels together, the female lock is placed over the male portion of the panel. When the first portion of the female lock is folded, that creates a single lock, which is a horizontal lock. If the second portion of the female lock is also bent, that creates a double lock, which is a less visible, vertical lock.
Double lock is the choice of most because of its longevity and looks.
Why choose standing seam metal roofing over corrugated roofing panels?
The single main reason why you would choose a standing seam roof system is because it is a better system, and the main reason for this is because when properly installed, no fasteners are visible, nothing pierces through the panels to attach it to the roof deck. This is all done under the panel, which minimizes the chances for leaks. Corrugated roof systems are installed by fastening through the panel into the roof deck, meaning the panel is now pierced.
