Hi there! I just put up vertical vinyl siding on my house and it is really simple! It requires J channel around it so it has a groove to fit into and then it just snapped together! Here's a video! https://www.youtube.com/watch?v=xOCIBdn8enk
When doing any siding project, you will need to check for any damage when the old siding is removed, and you also need to make sure that all the drip flashings are working.
yes, vinyl definitely has to have its hanging track because you can’t nail through it like you do wood siding
