What is a requirement for architectural metal roofing installation?

For architectural metal roofing installation, a continuous or closely spaced deck is vital because it provides the necessary support and stability for the metal panels. This type of deck helps prevent the panels from sagging and ensures that they maintain their structural integrity over time, especially under varying weather conditions. A continuous deck creates a uniform surface, which is crucial for proper water drainage and minimizes the potential for leaks.

While wide spaced decking can lead to unsupported spans that may compromise the roofing system, and insulated panels or wooden battens can serve specific purposes in different roofing applications, they are not fundamental requirements for the installation of architectural metal roofing itself. The closely spaced deck is specifically aligned with the needs of metal roofing systems for optimal performance and durability.
