Securing a chimney cap

A few years ago I had a chimney relined, and they replaced a long-since missing chimney cap. Problem is, it kept coming off--the bolts that hold it onto the chimney by friction were not evidently enough to hold it it. Part of that is I get a lot of wind down here near the water, and partly it's just how things are. The came back a several times to secure it, finally ending up attaching the cap to the flexible chimney liner.
Problem is, this keeps it on, but it rattles back and forth; you can hear it banging around through the entire house. Last spring I use some of that heavy plastic weatherseal tape to hold it in place, but it's apparently not UV-proof, because it slowly disintegrated.

How can I hold this thing in place?

You could do several things. Use lager screws to hold it on. You could take some strips of flashing and strap it over the top and fasten it to the roof.

I would probably remove the screws and use a hammer drill to carefully make some indentations in the clay tile flue. That way the screws engage with something when you tighten them.
