Just grab it and as it is falling grab the actual roof and you are good to go.LOL

But really try to never have to grab a gutter.

I actually laughed out loud at the "hit my face" bit...

yeah, at my high school there was a really sweet way to get onto the roof, great parkour. And then they removed a dumpster we needed for the combo, and suddenly there was a ~20 foot wall we had to climb...
Time to find a new way to the roof!

So we ended up finding a different way onto the school, where we tic-tac'ed off a wall, onto a perpendicular wall, and we had to grab onto the gutter.

We didn't realize it was a gutter the first time we did it, though... Luckily, it was very, very strong. Strong enough to hold us while we pulled ourselves up.

We got lucky though. Normally, i wouldn't even touch a gutter. I've cleaned my fair share of flimsy ones, and it's not something you want to grab on to..
