H & W Services Group LLC did a complete tear-off and re-roof job for me on a fairly large roof with a substantial number of dormers and valleys in a coastal environment, and with the difficult working conditions of an active restaurant/retail commercial site. They showed good knowledge of critical installation issues, committed to installing the roof correctly for the expected harsh weather conditions (some during installation and certainly for the life of the roof) and did a very good job of getting it right the first time. When one part of the installation wasn't just right, they corrected it completely. I do not believe I could have made a better contractor selection.
