Hardie Plank on angled side gable
I'll be ripping off rotted wood siding on a side gable. It meets the roof at an angle (see photo). I realize I have to wrap and flash. It's 50's era, so I'm pretty sure I'll find sheathing. Do I put the Hardie Plank starter strip along the roof line (red line on photo)?
Any other advice for a DIYer on this job?
Thanks!

No hardie on the angle. Just make sure you have good flashing and cut the hardie planks at the proper angle to keep them level and hold them about 3/4" or so from the flashing. You don't want the siding exposed to water and you want it to drain away from the siding. You should have step flashing under your shingles and up on the side for this continuity.

No, your only piece of starter strip will be a little tiny triangle under the bottom edge of your very first piece at the bottom. Be sure you keep the siding 1 to 2" above the roofline as the mfg recommends in their instructions. (one tip is to just lay a 2x4 along the roof... if you want a 1 1/2" space... and use it as a guide to help you measure how long each piece should be) You would also be wise to prime- and paint- all the cut edges along the roof.

Hardee needs 2" of gap from any solid surface per there install directions.
I use 1 X 4 vinyl lumber held up 1" from the shingles, a strip of Z moulding then the preprimed and painted Hardee siding.
Hardee was very clear install directions.

Thanks! New question - Pre-finished or paint?
Is pre-finished hardie plank any better than primed, paint it yourself? Since I'm doing a small section, painting in advance isn't any big deal. But will the finish be as good? Yes, I use quality paints.

IMO the factory finish isn't as good but a lot depends on the quality of the coating you use. The cut edges no longer have any coating so either way it's beneficial to coat the cuts!

Prefinished siding will have a warranty on the paint job. If you DIY and use a quality paint, it should also have a warranty- but through the paint company (i.e. SW Superpaint or Duration or Emerald) The caveat is that you will have to be sure the installation and priming and painting of any cuts done in the field, as well as the caulking used, will all be "variables" that could possibly affect any warranty.
Prepainting makes sense when blind nailing and when you have the exact color matched caulk (like OSI Quad) and factory touchup paint. Plus you have to be careful not to scuff it up when you're installing it. Some people prepaint their own before installing it.
