From experience, strap to chimney is ok, BUT don't count on the
strapping for real strength. The strength in a wind comes from how ell
you do the guy wires. But putting the antenna up on a calm day is a
lot easier. oh yeah watch out for the pole to accidentally punch the
roof and causing a leak, so prevent that too
As others have said, using a chimney mount is quite easy, and secure if the
chimney is in good condition. I've used them for decades at several
different houses. If the masting is over 10 ft. and/or the antenna is large,
it's best to guy the masting. I just installed a new chimney mount on my
current house and bought a Channel Master 3080 chimney mount kit which has
heavy duty brackets and 12 ft. long straps. I got it for $15 from
Amazon.com. Some kits have straps that are only 6 feet long so measure your
chimney before you buy.

This was common on older homes, and worked well as long as the chinmey
was solid. However, you may be in for a shock if you have a newer home,
because most new homes no longer have a chimney. Modern furnaces only
need a pvc pipe venting out the wall to get rid of exhaust.
Over time (years), the gases released by your chimney or flue pipe have
a nasty effect on the antenna, pitting the aluminum quite badly,
possibly having an impact on reception, or at least that is what I have
seen at my location over a span of 5 years.
