Help is it too late to prune rambling and climbing roses being trained over structures that are pointing up in areas?

The shoots pointing up or will I kill it?

You absolutely won’t kill it by chopping off some wayward shoots. But it;s hard to understand what your problem is here? If you can tie in this year’s shoots so they are horizontal they will throw up flowering shoots for lots of lovely flowers. If you need to cut them back be aware they will just carry on growing from somewhere else. Photo would help if possible.

Just tried but really hard to show. Imagine an arch stem over a shed and another over a pergola.

The rambling rose ( Albrighton)arched over has shoots growing upwards to the sky on the shed. One I’ve manage to tie down and could do two more but there are 3 thick stems pointing up to the sky that will not bend or be moved down across the roof.

The pergola climbing rose ( Generous Gardener)has another successful arch with I thick side stem shooting up dh should have pruned before. This too has shoots from the man arch pointing up and I may be able to tie down some onto the pergola but not all.

I would bend over and tie in as many of the thick pointing up shoots as you as you can. The ones you can't I would (if you can reach) cut off the top third to encourage more shoots lower down.
