Expert Verdict — Reviewed by the SuperArbor Pro Desk
Start tapered runs at the low point with thinner classes like this 1.00–2.00 in. panel and step up through the thicker classes toward the high point. Keep the taper direction consistent across rows so drainage paths stay uninterrupted. Verify panel attachment with the membrane manufacturer's requirements.
Practice safe lifting and roof work; use fall protection when installing insulation on any roof.
