Is it right for you?

- Twist-lock aluminum pole from 6.2 ft to 21 ft
- Overhead reach of 12.2 ft to 27 ft, according to Snow Joe
- 2-year limited warranty for household use
Cons

- A 21 ft pole may not reach the upper part of a tall two-storey roof
- All-metal pole and blade: keep it well away from power lines
- No replacement head or pole part number published
- Best for
- Owners who want a metal rake head on a light telescoping pole for clearing the lower edge of a pitched roof from the ground.
- Not for
- Anyone who wants the lightest tool (the poly-blade RJ204M is 4.8 lb), who needs more than 21 ft of pole, or whose eaves sit close to the service wires.
Our verdict
The Roofer Joe RJ205M shares its pole with the RJ204M: aluminum, telescoping from 6.2 ft to 21 ft with a twist-lock knob, for an overhead reach of 12.2 ft to 27 ft according to Snow Joe. The difference is the head, a 25 in wide, 6 in tall aluminum blade, which Snow Joe pitches for clearing heavy snow and debris from a roof without a ladder. The metal head brings the weight to 5.7 lb, nearly a pound more than the plastic-blade version.
Choose between the two on blade material and weight; reach, warranty and assembly are the same. Snow Joe gives a 2-year household warranty and ships to Canada from its US store, priced in US dollars. Before you start, read our guide to preventing ice dams: raking the eaves is the quick part, and the guide covers what stops them coming back. The lighter RJ204M is the poly-blade alternative.
Assembly and safe use
Screw the two metal braces to the head with the short hex screws and locking nuts, then fix the braces to the pole with the long hex screw. Keep the shipping cap from the top of the pole for storage. Use it from the ground.
Power lines: the pole is aluminum, which conducts, and Snow Joe’s manual says nothing about power lines. Look up before you extend it, keep pole and blade well clear of every overhead line, including the wires that run to your house, and leave any stretch of eave near them alone; NDSU Extension’s ice dam advice also warns to keep roof rakes away from power lines.

Snow Joe RJ205M questions
Aluminum or plastic roof rake blade?
Snow Joe sells the Roofer Joe both ways on the same 21 ft pole. The aluminum RJ205M weighs 5.7 lb and the polycarbonate RJ204M 4.8 lb; Snow Joe pitches the aluminum one for heavy snow. Both reach about 27 ft overhead and carry the same 2-year warranty.
Can I use it near power lines?
Keep it well away. Pole and blade are aluminum, which conducts, so keep both clear of every overhead line, including the wires to your home, and leave any eave near them alone.
Is it sold in Canada?
Snow Joe ships to Canada from its US store, in US dollars, with extra charges for Canadian customers.
