Jake as my rep did a great job keeping in contact with me. He followed-up after the job was done to make sure it was correct, and had a crew come out to remove some ridge vents that weren't supposed to be installed.
My only issue was with the roofing crew themselves. Having at least one team member who was fluent in English would have likely prevented the extra ridge vent installation that Jake has asked them not to do. Also, each day after they left I had to pick up empty soda cans that were just tossed in my yard by the crew.
