I’m assuming that you have cedar shake shingles. To overlay or not…..that is the question. It really depends on what’s beneath the cedar shakes. If you have a good nailing substrate like plywood, OSB, etc. and there are no major bulges etc. in the shakes, go ahead and overlay them. However, if you don’t have a good nailing substrate, cedar is not a good nailing surface (they split, crack, etc.). As someone else pointed out - if you overlay, expect to pack out the door and window jambs because of the J-channel which goes around them. To have the J-channel sticking out past the jambs would be unsightly as heck. You could use what’s called “fan-fold insulation” behind the new siding. Between that and the existing shakes (if you do overlay them) you’ll have a nice insulating factor.

I would tare it off if it was own house.
You might be able to float the siding over the old wil a foan backed siding, then you have to pack out the windows and doors because the ” J ” chanel is about 7/8″ proud, but i would still tare it off

You need to remove the wood shingles in order for the vinyl siding to sit correctly.
