Roofing nails 

Roofing nails can be made with a variety of types with Flat head or Umbrella Head, Diamond Point, Smooth Shank and Twisted Shank. Different shank types offer various properties for the roofing nails and give different application effects.

Smooth shank nails are the most popular types, with economic cost due to less cost of materials.

Twist shank nails are used extensively in post-frame construction due to their superior performance. It had approximately twice the withdrawal resistance of smooth-shank nails of the same diameter.
