I have been practicing taking close up shots of my exhaust stacks and roof vents but am having trouble finding out how to reach out to the roofing industry for commercial inspection business. has anyone had any luck getting roof inspection work. do you go to the roofer, insurance company or roofing supply company's. I did shoot some commercial work and that was good because not many people want to get on top of a large commercial building. Let me know your thoughts.
