We own both the Werner 13’ and 17’ telescoping ladders. I had the 17 foot ladder first, for use in the shop, but the ladder compacted at four rungs high was about 3 inches to tall or long to fit into the van for easy transporting. I searched the Northwest for the 13’ ladder, and finally found one for less than $100 at Lowe’s in Seattle Washington. The Werner and Little Giant seem to be rated the same, but the Little Giant costs about $100 more.
We have been full timing for about 18 months, and I seem to use the ladder about once a month. I have been on the roof several times, replacing both skylights and two fans. The shorter 13-foot ladder allows easy access to the roof, but one has to be comfortable with standing on the roof and turning your back to the edge, and backing down a ladder, as it doesn’t stand tall enough to give easy hand holds to remain upright.
