Panel width and wind/snow ratings determine screw row spacing. Thicker panels need more screws than thinner. Longer panels need closer screw spacing to resist uplift. Proper length penetrates the deck, not rafters. Gauge matches panel thickness. Follow manufacturer guidance on quantity to prevent roof failure.
