Is there a special name for ladder stand-off that rests on the roof tiles?

A "clip-on" stand-off isn't suitable for putting on the roof because it tends to lift off the ladder. But when the soffit is wide a normal stand-off won't keep the ladder away from the gutter.

Like in this video from 5 to 10 seconds.

Thanks C, that was exactly what I need to know. For some reason I can see your answer in my notifications but not listed under the question. I have now modified my own stand-off with a couple of optional bolts through the forks to prevent them lifting off the rungs.

Acro Building Systems roof ridge ladder hook #11084 fits most all ladders. Can be used on tile, metal or any roof where protection is necessary. I'm sure there's others but that's the one we use.

Better to ask a contractor or perhaps a ladder manufacturer to receive a valuable answer
