Which of the following materials is NOT typically used for guttering?

Brass is not typically used for guttering materials in residential or commercial roofing systems. While brass can be a durable and aesthetically appealing option, it is not practical for gutter systems due to its higher cost and susceptibility to corrosion when exposed to certain environmental conditions, especially moisture and acidity found in the atmosphere.

In contrast, steel is often used for its strength and durability, and it can be galvanized for added corrosion resistance. Copper is highly valued for its longevity and classic appearance, though it is also more expensive. Plastic, particularly vinyl, is popular due to its lightweight nature, ease of installation, and resistance to corrosion. Each of these materials serves specific functions and performance needs in gutter systems, but brass is less common largely because it does not provide the same balance of cost-effectiveness and practicality that other materials offer.
