Compared with wire nails, umbrella head roofing nails have higher
profit and less competition,while it need higher skill to produce
roofing nails.
A roofing nail is mainly used for installing roofing (sometimes for
water resistant drywall,tile backer board etc). The main feature
that distinguishes a roofing nail is its large head,galvanization
appearance, which is usually much larger and flatter than other
types of nails. This permits the nail to hold down roofing felt and
roofing shingles without tearing through the material. Roofing
nails generally come in lengths of 1 to 1.75 inches (2.54 to 4.44
cm), although shorter and longer nails can be found.
The process of how to make a roofing nail is :

diameter.the difference with the coming nail making is that this
needs to add a twist device to make the steel wire spiral,the aim
is to help the spiral grab the wood well.
Second step is make the roofing nails with roofing nail making
machine.this step looks simple but actually it needs skilled
operation to make one shaft one head,if not,there will be some
problems such as there is no head for the shaft or one nail body
have 2 head.but don,t worry for this problem,you can learn the
skills in your factory until you master all the skills perfectly.
Galvanization.Because the roofing nails should bear couple of years
rain,snow ,sunshine etc,so galvanization is a must to prevent the
roofing nails from rusting.
