Our coach has a ladder for roof access - however, having used it once - I'll never use it again. When you reach the top of ladder your on the fiberglass "rear cap" of the coach - which is more decorative than structural - and flexes a whole heap when my fat butt steps on it. Instead, I use a
Werner "Multi-Ladder" - which in the "straight" position is 17' tall and can be placed against the side of the coach. When placed on the side of the coach (roughly 12 feet tall) - it leaves me a 3 foot high handhold to make the transition from ladder to coach and/or coach to ladder. Once I'm up there ... the roof gets a "hands and knees" scrubbing followed by a hand waxing.
As others have suggested - any work on the roof is best handled by youngsters. As long as I limit it to once or twice a year - I can usually entice my youngest kid to take care of it for me. (Reminding him that I can easily spend a bit of his inheritance and hire it out seems to help him find the time and energy to give me a hand!
