    I live in a one story house and this ladder does everything I need it to..I use it inside for things like painting and changing light bulbs and batteries in smoke detectors and to get into the attic..and outside it is the perfect height for cleaning the gutters and getting on the roof if needed..It is a little heavy..but to me that just means its well made..Its easy to set up and adjust and its every ladder I could ever need and takes up very little space..I can actually store it in a small closet in the house and not even know its there...and the price was cant hardly buy a good quality step ladder with a 300lb. capacity for this price.let alone a 17' extension need for multiple ladders for different jobs ..this one does it all....cudos

    I would like to know is it easy to get on and off a roof with this ladder, other ladder I used had a little twist to it, and I did not feel safe on it.

    • I would feel fine climbing on to/off of a 12' roof with it.

    • This is one area where I believe the Little Giant and Werner are a safer alternative, when used as a roof ladder. All the 17' multi-ladders can be extended to nominally 17', but the latching mechanism is far sturdier in the Little Giant and Werner IMO and according to many reviews. Now I have used the very similar Vulcan 17' not quite fully extended to get up to my garage roof and it is every bit as sturdy as a good extension ladder for the 13-15' rise. I do question the Cosco latch's sturdiness in this configuration, and this has been reported on other reviews as a problem.

    • I'm not a fan of heights or ladders. This one feels solid enough for me on a single story house...

    • As long as your roof is lower than 17', you can... I am using it today to climb to my roof to install a vent.
