How many nails in each roof shingle.
One and a half inch roofing nails typically have a large 11 gauge shank and an oversize 7 16 inch flat head.
320 nails will be needed to install a square of standard 3 tab shingles assuming four nails per shingle and 80 shingles per square.
In high wind areas you need five nails per shingle or 480 nails per square.
If you have high wind areas you will want to use five nails pers shingle equating to about 480 per square.
The rationale behind the number is that in most cases four nails are the right number of nails to do a quality job.
In all use four nails per 3 tab shingle.
High wind areas and other types of shingles may need more.
Place nails in the three tab shingles about 3 4 inch 1 8 centimeters above the cutouts near where the tab meets the upper part of the shingle.
Standard roof installation requires four nails per shingle.
When nailing shingles proper penetration into the roof deck is essential to ensure the nail and shingle remain secure.
When reshingling a roof shingle nails need to be placed appropriately in order to keep elements out and the shingles on.
