Christian Roofing Inc. does good work. They can be a little bit pricey, but they've worked with me in the past. I've used them for six years. Every year they've done a new roof on one or two of my buildings. This year they're doing the last two roofs. They work quickly and clean up their mess. The important thing is that the roof doesn't leak. They've even done my personal home. One time they let me buy the materials in advance to save money. Another time, they let me pay in installments. I'll never forget the flat roof they did for me, using a robot to spread the material. They're excellent.
