Ladder Different Windows

The 24' ladder often comes up short depending on grade/roof pitch. (Probably would make this specific example) The 35' is a beast at this angle. The pitch is dangerous and downright deadly below freezing.

Any suggestions? No obvious discussions in history. (The picture I found online but suits example well; some of the dormers are farther back and pitch is around 8-10 on 12)

FETC,

I did the math, I just didn't include it, but I'm basing the following on the house in this post.

Figure 3ft from grade to porch floor, 8ft from porch to second floor, 3ft from floor to sill = 14ft but just to be safe, figure 15ft from grade to sill.

I estimate the porch to be no more than 6ft deep, so go 10ft out from the porch, 16ft.

$a^2 + b^2 = c^2\,$

225 + 256 = 21.9ft sq.rt so the ladder needs to be 22ft long.

alternatively,

$b = \sqrt{c^2 - a^2}. \,$ where b is the distance out from the house

so with the ladder extended to 24ft, and a rise of 15ft you would have to be out from the house 18.7 ft.

I do believe that a 24ft extension ladder would make the window sill with no problem.

"So what if the ladder is in the way of the front entrance, that shouldn't keep you from doing what has to be done. You're making a rescue, not painting the house."

Just to be clear: I didn't know at the time, ladder placement for a rescue was being discussed. I was thinking more along the lines of secondary means of egress. And Jack, I couldn't agree more. Improvise,adapt, and overcome.
