What are extra large head clout nails for?

Fixing roofing felt and soft board to timber. The extra-wide head grips the felt over a larger area than a standard clout, so it is less likely to tear through.

What size clout do I need for shed roof felt?

13 to 20mm is right for felt on standard shed boarding, so the nail holds the felt without coming through underneath. Go to 30 to 40mm only for thicker build-ups.

How are these different from standard clout nails?

Same short galvanised nail, but with an even larger head. That extra bearing area suits soft, tear-prone materials like felt and membrane.
