How do you guys clean windows over steep roofs?

How do you guys get to the screens above steep roofs? Do some of you even bother with over roof houses?

I admit I’ve never been on a roof and looking at some of my pest customers’ houses they have some pretty steep roofs with windows above. I know about tying off etc, where I’m at we don’t have any “roof tie off” requirements at least for homes that I’m aware of, and Id rather not test gravity

Even if it’s an “outside only” job I tell them that I will need to come in the house
to remove and replace those types of screens. Everyone is different
but I have my limits as to what pitch I’ll walk on.
