How to replace aluminum with vinyl windows on T1-11 siding house?


I'm going to be replacing my old dual pane aluminum windows with vinyl windows soon. The house is wrapped with vertical T1-11 siding and the old window nailing flange is underneath the T1-11.

My question is, what's the best approach to cutting out the old window, installing the new vinyl window and flashing it properly?

Some say, to cut 'back' the t1-11 one inch or so around the window frame to expose the nailing flange, pull nails and remove window, install vinyl window and 'replace' the cut strips of t1-11. Options thereafter are to trim around the window to hide the cut lines.
What about flashing? Also, if I trim aound the windows how do I seal the top trim piece to prevent water from running down the vertical seams of the siding back behind the trim? Seems like alot of void to fill with caulking..

Please help! This has to be a common home improvement but the DIY details are vague at best.

is there sheathing or paper under the t1-11?

you would install a metal Z flashing under any paper and over your head trim..generally speaking

No the t1-11 is nailed directly to the framing. No vapor barrier or anything. There's a corner of the t1-11 on the back of the house that's coming loose at the bottom corner. I can pull the corner back and see 2x4 and insulation.

Yeah, this is an old '70s built "vacation" home with 2x4 exterior walls. Obviously thermal efficiency was not a concern then.

~EDIT~
I just came across this DIY with decent photos. This is more or less the procedure I had in mind for the R&R or the window but my concern is still flashing the top trim piece.
Unfortunately not all of my windows are under a soffit like in the DIY so proper flashing would be crucial.

just remember you can't ''seal'' horizontal joints like window heads with caulking,you need metal that goes behind the siding and then out to daylight over trim

you can do the same type of thing at the sill,if there is no paper under the siding i would install a sill flashing that drained directly over the top of the t1-11

This would require removing the bottom nailing flange on the window wouldn't it?

no,not necessarily

if your cutting back the siding for the flange,you can install the z at the bottom of the cut,wrap your sill flashing over it then install your window

the idea is you want drainage to be over the siding instead of behind it

this is the idea but in stucco,notice the metal bent over the stucco,the self adhesive flashing brought down over the flashing and the trim installed over the top

I guess the other thing I should mention is...
I'm open to other thoughts or ideas. It seems 50/50 whether people install the windows over or under the T1-11.
Under sounds like a lot more work. but over seems like it would be hard to flash around...

I dunno...
For as common as a project like this seems, there's not much "solid" info available.

It's really pretty simple, do it fast and easy and rely on caulking to keep the water out or spend a little more time to do it right.
