Fred pretended :
As you may know from my recent posts, I have flat roof troubles. I
need a ladder to get up there.

Unless you have a good reason for a short triple, I generally find a
long double more useful. I have one 4m double and a 4m single. The
double can be split to allow two people to use each section. The double
is also long enough to gain access to the roof and gutters.
