Roofing felt nails, also widely known as clout nails, are primarily designed with a large flat head to securely hold thin sheet materials like roofing felt, underlayment, and tar paper to timber roof structures.
Stainless steel roofing nails offer maximum protection against rust and corrosion. They are highly recommended for coastal environments, long-lasting roofing installations, or when working with corrosive timbers like cedar.
The broad, curved design of the umbrella head helps prevent water penetration by tightly capping the nail entry hole, providing superior waterproofing security for metal and corrugated roofing panels.
Ring shank roofing nails feature grooved rings along the shank that grip the wood fibers tightly. This design provides much higher holding power and prevents the nails from backing out due to temperature changes or wind uplift.
Clout nails are a specific type of short, thick nail with a large head. While similar to standard roofing nails, clout nails are commonly used for securing roofing felt, sheet metal, and plastic sheeting to wood decks.
Generally, roofing nails should be long enough to penetrate at least 3/4 inch into the roof sheathing. If the roof deck is thin, the nails should pass completely through the deck to ensure optimal holding strength.
