They called me this morning.  They asked for me by name and I hung up.

I received a call today...the caller ID states "Denver Roofs". We've had a lot of local hail damage so the phonies are coming out of the woodwork. No listing on the web...I suspect number spoofing. I told them I had the roof handled and hung up.

Called again.  Now a Robo-Call.
