FAQ
Common questions
Is 256 nails per square universal?
No. It is an example specification for one common shingle product, not a universal rule.
Should I include starter and ridge-cap nails?
Add an allowance or calculate those separately when your product requires additional fasteners.
Can high-wind fastening change the count?
Yes. Follow the manufacturer and applicable requirements.
