What fasteners are appropriate for attaching slate to roof decks?

Copper slating nails are the appropriate choice for attaching slate to roof decks due to their properties that are especially suitable for the unique requirements of slate installation. These nails are highly durable and resistant to corrosion, which is essential because slate roofing materials may last for many decades, needing fasteners that will not degrade over time. Additionally, copper has natural antimicrobial properties, which can help prevent the growth of moss and lichens on the roofing surface.

Using copper slating nails ensures a secure hold that accommodates the natural expansion and contraction of the slate as temperature changes, which is important in maintaining the integrity of the roof over time. The design of these nails often features a larger head that helps to hold the slate more firmly in place and prevents the slate from cracking during installation.

Other fasteners, such as zinc screws, galvanized roofing nails, and plastic roofing fasteners, may not provide the same longevity or compatibility with slate roofing. Zinc screws could potentially lead to galvanic corrosion when in contact with copper, which is detrimental to long-lasting performance. Galvanized nails may also corrode over time, especially if they come into contact with moisture. Plastic roofing fasteners may not provide sufficient strength or hold, potentially leading to failure in windy conditions or when subjected to
