For serious and determined roof snow removal, the all aluminum roof rake with an aluminum blade stands up better than the plastic blade. All aluminum roof rakes cost a little more and can be difficult to find at local stores. Aluminum blades are tougher than plastic and work a little better for pounding on that ice build-up.
Hey there buddy, just get out the H out there and go pound on that roof ice with yo new, all aluminum roof rake .... yo! .....
For about $45, shipping included from New Jersey, Ebay has or had some all aluminum, Snow-Joe brand, adjustable out to 21' length. Straight out of New Jersey, it's the same exact roof rake that Tony Soprano use to use on his New Jersey luxury roof ....... God bless Tony and his roof rake ..... yeah!
Need to rake it off the eaves before it becomes an ice dam. Need to rake it off a flat roof before it weighs too much. ....
Need to be VERY aware of overhead power lines. .... or you'll be visiting with Tony Soprano ......
