Steep Slope Metal Roofing

Classifying metal roof systems is a challenge, because of the many variations and types available. The first classification that is commonly used is Architectural or Structured system. The Architectural systems are applied over a structured deck, while the Structured systems do not require a structural deck and instead are fastened directly to rafters or purlins. The discussion here will deal only with Architectural Systems.

The first system will be a vertical panel system, where the panels run from the lower edge to the peak. A common variation of this is a standing seam roof. There are a number of panel profiles, batten or seam profiles and types of metal.

Another system is stone coated metal. These are metal panels that are coated with a granule similar to asphalt shingles that are epoxied to the surface of the metal. The panels are available in many different colors and profiles.

The next system is a long horizontal panel system, commonly called a Bermuda Panel. This system creates strong horizontal lines stepped up the roof.

The last system is a shingle type panel system. These panels are up to approximately 4’ long and installed similar to shingles. There are many different profiles available, imitating most other steep slope roofing materials.
