3. Building Code & Permit Fast-Brief: IRC R905.1.2 & R905.2 - Ice Barrier & Roof Sheathing Permit Standards
Roof Underlayment, Ice Barrier Eaves, and Shingle Fastening

Fastening requires a minimum of 4 nails per architectural shingle (6 nails in high-wind zones).
Is a Municipal Building Permit Required?
Yes in most jurisdictions when re-roofing covers more than 25% or 100 sq ft of total roof surface.
