Expert Verdict — Reviewed by the SuperArbor Pro Desk
SECUROCK is a strong choice where high wind uplift and hail resistance matter, because its through-core strength eliminates facer delamination risk common with paper-faced boards. Choose 1/2 in. or 5/8 in. for high-traffic or hail-prone roofs and keep board joints staggered from insulation joints. Adhere with a compatible insulation adhesive and let adhesive skim properly before placing boards.
Roof boards are heavy and panels have sharp edges when cut; use proper lifting technique, cut-resistant gloves and roof-edge fall protection.
