Depends on how big the tower is.
I have a 14 foot tower/tripod on my roof and it's been up there for years and
has worked great. I used to have my HF beam on it, but since then I have put
up 53 feet of Rohn 25 and I now use the roof tower for VHF/UHF/S band satellite
As for lightning, you can do a fairly decent ground system if you do it
correctly. Polyphaser has a good app note on their website. Look, if
commercial sites can put antennas and equipment on high-rise buildings and
create adequate grounds, it can be done on one's house.
