Putting Cable Clips onto Flat Roof - should I be worried?

[confused_palm]

Apologies if I am asking a daft question.

Recently had fibre broadband installed. A small section of the cable had to be routed near the flat roof. Instead of the affixing the cable onto the brick wall, the network engineer chose to put several nail-on cable clips directly onto the flat roof to fix the cable.

Should I be worried about future water ingress problem due to damage to the flat roof surface?

Yes, putting holes in the felt should be avoided. You could remove them and seal the felt.

Thanks for the advice. I will probably get in touch with the network installer to get the issue looked into.
