I used to carry 3 fiberglass ladders on the service truck; 4', 6' and 8'. Last winter I found a fiberglass ladder similar to the "Little Giant" made by Gorilla Ladders. It is 4' at its shortest and 8'at its tallest as a step ladder. You can work from both/either side and folded out it is a 13' straight ladder. It can be adjusted to set up on stairs. It cost 1/2 what a Little Giant does. It is heavy but very versatile. I also have an aluminum version by Gorilla that as a step ladder ranges from 5' to 9'. It is lighter than the shorter fiberglass. I still have my 14' Werner fiberglass step ladder. If it isn't tall enough for the job I set up scaffolding. Ladder rungs aren't big enough for me when I'm working with both hands up that high.
