Expert Verdict — Reviewed by the SuperArbor Pro Desk
For a 1 in layer, plan on roughly 32 sq ft of coverage per board and order 5-10% extra for edge fit and waste. Keep boards dry and flat before installation and stagger joints between layers. Match fastener length to board thickness plus deck type per the Versico fastening pattern.
Handle boards with cut edges carefully, and follow roof fall-protection requirements during installation.
