Most manufacturers have training videos online.AHS said:I'm looking to expand my company & would like to learn more about siding & window replacement. I currently offer residential roofing & exterior painting, I have a solid business structure (although I am fairly small in size) I learned roofing from the ground up & have done very well with it but now I would really like to expand into new services without working on a crew for the next year learning everything. So i'm curious if anyone knows of a good training manual or video to teach me the in's & out's of siding & window replacement. Thanks for any help!
