Birds pecking at roof shingles

What bird or squirrel eats roofs, a strip of copper or zinc at the Top keeps off mold and im sure animals, what did you have an organic corn base roof?? Its strange.

What kind of birds?

We go to a restaurant that has outdoor dining. To keep the birds out, they run nylon fishing line in a grid pattern across the open side of the deck. Rigging some fish line, if feasible, would probably keep them off.

Good idea, but get the heavy stuff, like 50-60 lb test. More visible, less likely to degrade. He doesn't want to be repeating the chore too often.

In my years; I've never seen enough grit, eaten by any bird (s) that might required new shingles. In fact, never saw a bird eat the grit from a shingle.

OP can set out a feeder for the birds and add grit(S) :)

Do you have a lot of bugs on your roof? I doubt it's the grit they're after.

And a cat or two.

Get a FiShock. Wrap spiral bare wires around a 2' piece of 3/4" PVC. Once they land on it, they will NEVER ever return to your rooftop.

My cats are old; now the dog (sight hound) picks up the slack.

I wish he would leave the dove alone...

Best response I've had thus far on how to prevent birds from pecking away and destroying shingles on roof came from a builder who told me to kill one bird, and throw it onto the roof. "Just let it rot there," he said, "and the other birds will never come back." Not sure how the neighbors will feel about a rotting bird displayed on a porch roof.
