While I was up in the loft last evening, fitting some loft insulation,
I noticed a 6 inch rip in the roofing felt. I could view the roof tiles
through it.

There is no evidence of water ingress. Can I safely patch this up with
duck tape or do I need a more watertight solution?

Providing it sticks OK, I would have thought that should be fine. It's
not as if roofing felt is subject to massive amounts of running water -
you'll find old houses don't even have it at all. Keep an eye on it to
make sure it stays stuck down.
