Kenny (in sales) came over a few days after I called for a quote. He was one of only a few who responded when I called. I've had many roofs done in the past 30 years so I know what to ask, and he had all the correct answers. After reviewing the quotes I received I selected C-Star. Although they weren't the cheapest I felt very comfortable with Kenny, plus they had good reviews while the cheap options had no or bad reviews. Another reason I chose them was that they install with a minimum of 5 nails per tile (I watched while they installed and they do use 5, and sometimes 6).
Due to the wind storm a few weeks ago there was a small delay before they came to do the roof, as they were busy doing repairs for those who lost tiles (a lot did in my area as I observed when I took my daily walk).
They arrived at around 8:30 and finished by 4:00. They did a very professional job and cleaned up everything, including sweeping for nails with a magnet. The roof looks great, the open valleys are straight, and the old bubbled tiles have been taken away, so I'm happy!
