I'm sure you [the roofer who did OP's mom's house] have spent a lot of
effort trying to build a
good name/reputation for your company. And, well... let's just say
that I have the ability to make a LOT of noise if this isn't
resolved."

Do you honestly expect OP's mom's roofer to respond to a threat like
that?

It's worked for me with various home work issues in the past.

Any business owner who works off of referrals and is any brighter than
a roofing nail does tend to care about their good name, not showing up
in the BBB database as having unresolved issues, or in google with a
long page describing in detail what a **** of a sloppy shoddy
businessman he is.

But if it's an apologist idiot who isn't bright enough to understand
the monetary value of good customer service, then, no, such a tack
doesn't tend to help.
