Sounds like a good plan. You will learn something about roofs every time you provide him with pictures. To give him value you could then start identifying problems before you even give him the pictures. You can easily find online sample reports from roof inspectors and home inspectors. Use those to get an idea of what you need to inspect and all aspects of a roof. Learn roof material types, flashings, chimneys, vent placement, ventilation and the types of roofs, low slope, gable, hip etc. You could even buy a used home inspection book on Amazon. You'll find that even if you know about roofs, there is probably a lot more to learn, especially code and best industry practice.Jaka thanks for your insight. I have a friend who is a licensed inspector. I plan on just doing the videos and pics and send to him and let him do the actual analysis. I will go with him to jobs and learn from him and eventually perhaps get licensed as an inspector down the road. Right now I want to focus on learning the ins and outs of doing the pics and putting them together in a format that the inspectors can use
Like many have said, keep in mind a primary goal and get really good at that. Also realize that you are a data collector unless you get certified as an inspector. Focus on collecting the best data you can.
Or surveys... Especially on marketing material. Scan(s) is a good option.InterNachi has a great course on roofs and how to inspect them, and I'm sure there are plenty of other sources. The main thing is don't refer to your work as inspections unless you are certified.
