How do I stop magpies pecking among the gravel on a flat roof above my head?

Catch a crow and domesticate it. Problem solved! Except for the fact that it will bring nice gifts in for you to admire.

1 new wiper blade

1 new small glove

beer opener

yes, possibly, even jewelry!

If it gets real bad, the neighbor will shoot it.

Domesticating a magpie is possible, too I think. Just not sure how to do it or how it will turn out.

Just imagine, your own bird patrol!

As flossie says, suspend some netting above the roof to stop them landing there. Or sonriel's imitation owl or a hawk may have the necessary effect - we did have a plastic hawk when we had pigeon problems, it certainly kept them away! I think it was supposed to be a sparrowhawk, but in any case it looked pretty realistic perched there. A bit like this: http://www.pigeoncontrolresourcecentre.org/html/re...

You need to deny them access to the roof.

Get some garden netting, the sort used to protect fruit bushes. Arrange the netting over the roof, you would have to fix brackets (wood homemade?) on the walls to support the netting.

We used to do this as an anti pigeon method.

This website has further ideas, good luck!

Cover the roof with chicken wire mesh.

You really cannot I'm afraid. If it is getting really annoying then the best thing to do is replace the gravel with a "green" roofing material such as sedum mats.

Put a fake owl near the spot it will keep them away

a well-timed firecracker or 3 will solve the problem.

sprinkle your roof with something they don't like, all clear anything that attracts them.

Gun them down
