Expert Verdict — Reviewed by the SuperArbor Pro Desk
Six-by-eight is the workhorse step flashing size for standard-exposure asphalt shingles at chimneys, dormers and sidewalls; 28-gauge galvanized steel is the common residential choice. Install one piece per course, lapped by the next shingle, and integrate with housewrap or lapped WRB, never behind it. Use head-wall and counter flashing above, and add compatible sealant where the manufacturer's details call for it.
Metal flashing edges are sharp; wear cut-resistant gloves and follow local code and manufacturer's instructions for roof-to-wall flashing installation.
