I love being a DIY-er. This includes everything from building my outdoor kitchen to laying new floors, and even installing my roof a few years ago. I guess you can call me a handyman of sorts. Anyway, I also have a brick and mortar business that is in need of a new roof. However, I hate the idea of hiring out for this job as I generally can figure most things out pretty easily. I just don’t really know how to build a flat concrete roof. Can you guys help me out?
