Best Roof Rake for Snow: Pole Length by Story, Wheels and Power Lines
A two-story eave takes 20 to 24 ft of pole to reach 4 to 8 ft up the roof. Pole math, wheels for shingles or metal, the 10-ft power line rule, five picks.

Your two-story eave is 20 feet up, and a 15.5-foot roof rake won't touch it from 6 feet back. A foot of wet snow on the first 4 feet of a 40-foot eave weighs about 3,360 lb (FEMA: 21 lb per sq ft). Buy the pole for your roof.
Quick pick: Avalanche! 500 (fiberglass pole) for one-story shingles; add its 8 ft kit for two stories. Metal roof: the Avalanche! 750 (plus the kit for two stories).

How long a pole your roof needs
The math: pole to the edge = √(feet out² + (eave height − 5 ft)²). The pole has to clear the gutter, so add the feet you want to reach up the roof.
One story (10 ft eave), 6 ft out: 7.8 ft of pole to the edge, about 12 ft to reach 4 ft up, 16 ft for 8 ft.
Two stories (20 ft eave): 16.2, 20.2 and 24.2 ft.
The picks on that two-story: 15.5 ft (Avalanche!) falls short of the edge; 21 ft (RJ204M) reaches about 5 ft up; 23.5 ft (Avalanche! plus kit) about 7 ft; 26 ft (RJ207M) about 10 ft.

Shingles, metal or solar
Asphalt shingles: the Avalanche! 500 listing says its 1.5-inch wheels glide over shingles.
Metal, tile, cedar, solar: the Avalanche! 750 listing names those, with 3-inch wheels.
No sharp edges: FEMA says metal snow rakes can damage roofing.
Metal sheds fast: FEMA calls metal panels slippery roofs that shed snow easily. Stand back.

Power lines: the 10-foot rule
Look up first: OSHA says keep snow rakes 10 feet from overhead power lines and use extendable, nonconductive poles.
Metal poles: FEMA says metal snow rakes pose an electrocution risk. Both Snow Joe poles are aluminum (the RJ207M head too); Avalanche! poles are fiberglass (the kit's couplers are aluminum).
Wire within 10 feet of the swing? Don't rake that side. Hire a pro.

How to rake without hurting the roof
Leave a layer: FEMA says leave at least 2 inches of snow on the roof.
Small bites: OSHA says pull small amounts so falling snow won't bury you.
Not from a ladder: OSHA advises against it. FEMA adds roof snow can slide at any moment; stand outside the slide zone.
Lower strip only: clear what you reach from the ground. Don't climb for the rest.
Sagging ceiling or popping noises? FEMA calls those overstress signs: get out, call your building official.

Where the snow lands
Clear the drop zone: OSHA suggests keeping people back 10 feet from where snow will fall.
Off exits and vents: FEMA says keep it away from exits, downspouts and vents.
Then the walk: see how much ice melt you need, or the best snow shovel for a gravel driveway.
