When installing a metal roof certain steps must be followed including what panel is the best for certain applications and a mechanical lock standing seam metal roof panel is the best panel out there for many reasons including:

When the roof is slope is less than 3”/12” is recommended to use a Standing Seam Metal Roof panel that can be double locked to keep the water out, this mechanism is very similar to can food but instead of keeping the water in it keeps the water out.

Very effective for any applications under 3”/12” slope, this installation method will require more labor and additional tools to complete the seaming process.

This Standing Seam Metal Roofing panel has no ribs and its the most used by homeowners, when the metal roof is fabricated using steel galvalume versus aluminum it has less thermo expansion helping against oilcanning but not always it can be fabricated with steel for example a property near or with less than 1500 feet from the ocean will not receive or be approved for the 40 years finish warranty since steel will corrode much faster compared with an inland metal roofing installation due to salt spray or salt in the air. When installing an aluminum standing seam metal roof flat panel it is highly recommended the installation of a backer rod under the panel to control the expansion of the panel, not really noticeable and it does a great job against oilcanning.
