I've dealt with those on inspection list plenty.
$1000.00 not looking at it then I'd go buy $30 dollar aluminum roof paint and 2 tubes $8 silicone. Take pics for owner or buyer and call it day. Is it a rip off, absolutely. Then again you were more chicken then me to go fix it 😁
Typically almost all I have seen never needed replacing. Some are made of stainless. They still need sealing with silicone or roof cement every couple years but who bothers. Its good practice to replace when you get your roof done because you'll get a better deal. If you get gutters cleaned get pics of areas surrounding chimney and cap. I've been to New houses that leaked because of bad flashing or no sealing. If you lived close to me I'd take your money 😉
