Roof Ladder Jack – Adjustable, Safe, and Built to Last

Work smarter, faster, and safer on any pitched roof.
Whether you’re a contractor, roofer, painter, or serious DIYer, our adjustable roof ladder jack gives you a stable, level work platform even on steep pitches (1/12 to 16/12).

Why Choose This Ladder Jack?

• Universal Fit: Hooks securely onto most extension and step ladders, engaging two rungs 12 inches apart for maximum stability.

• Adjustable Arm: Integrated screw-jack angle adjuster keeps your plank level even when the ladder is laid flat on the roof.

• Pitch Ready: Works on roof slopes from gentle (≈5°) to steep (≈53°).

• Solid Build: Heavy-gauge steel channel and welded arm ensure rugged durability and load support.

• Safety-Minded: Includes plank stop, tie-off points, and wide hook surfaces for grip and reduced slip.

Key Features

• Dual Hooks: Approx. 10-inch hooks grip two rungs, spreading the load and preventing slip.

• Three-Sided Channel: A 12-inch C-channel spine connects the hooks and resists twisting.

• Heavy-Duty Arm: 18-inch arm supports standard scaffolding planks or staging boards.

• Fine Angle Control: Screw-jack adjuster provides precise leveling and strong lock-down at any angle.

• Plank Capacity: Supports standard 12-inch wide scaffold planks (follow plank and ladder ratings).
