This includes capping the windows installing a moisture barrier and sizing them. Preferably i always would do roof windows siding.

It is just more beneficial to start with the windows. For straight runs some contractors like to run up the siding and then place soffit j on top. Ideally you d do them at the same time. However with advancements in vinyl siding technology and manufacturing you can get much richer deeper and brigher colors.
