High slope roofs must be constructed with materials that are:

Corrosion resistant and minimum 12 gauge
Corrosion resistant and minimum 11 gauge
Not corrosion resistant and minimum 11 gauge
Corrosion resistant and maximum 12 gauge

The correct answer is: Corrosion resistant and minimum 11 gauge

High slope roofs are subject to various environmental conditions that can affect their longevity and structural integrity. The correct answer emphasizes that the materials used must be corrosion resistant because high slope roofs are often exposed to rain, snow, and other moisture. Corrosion resistant materials help to ensure that the roof maintains its strength and durability over time, preventing issues like rust that can lead to leaks and structural damage. Specifying a minimum gauge of 11 is also critical, as this thickness provides the structural support necessary for the roof to withstand elements such as wind, weight from precipitation, and thermal expansion. Using materials that are too thin could compromise the integrity of the roof, leading to potential failures. This combination of corrosion resistance and the specified gauge is important for high slope roofs due to their unique challenges and performance requirements.
