Many thanks. This was the info I was hoping for. I don't want my wife or me f ing on a 8 meter high roof. I'd rather have a professional crew with right equipment do that.

Is it a hot tin roof?

My apology. I noticed my original post was not clear. They nest underneath the Thai style roof. So even removing the gutters will not stop them from doing that.

Well for a start, without the gutters to perch on, birds would find it difficult to fly straight in, secondly there are plenty on the market to prevent that, depending on the profile of the roof. but they could still nest in the gutters.
