What type of fasteners are used to install slate shingles?

Aluminum nails
Steel screws
Copper nails
Plastic rivets

The correct answer is: Copper nails

Copper nails are the preferred type of fasteners for installing slate shingles due to their durability and resistance to corrosion. Slate is a natural stone that can last for decades, and copper nails complement its longevity. Unlike other materials, copper does not rust or weaken over time, which is crucial in maintaining the integrity of the roof against harsh weather conditions. Additionally, copper nails have excellent holding power, ensuring that the slate remains securely attached. This characteristic is especially important for slate roofing, which is often installed in areas prone to heavy winds and precipitation. The other fasteners, while they may be used in various applications, do not provide the same level of performance for slate roofs. For instance, aluminum nails can corrode over time when in contact with slate, leading to potential leaks. Steel screws, although strong, are not ideal for slate installation because they can rust and weaken. Plastic rivets lack the strength and durability required for roof installations, making them unsuitable for heavy materials like slate. Hence, copper nails stand out as the optimal choice for this specific roofing application.
