I had Hardie Architectural Panels installed in Dec 2023. I noticed that several boards have lifted and some have moved past the T flashing between the top and bottom boards as well. I would like a referral for an inspector in Vancouver, WA or nearby who specializes in this new siding material.
Hi Alice, I’m not sure who to direct you to in Vancouver, but here is South Florida improper Hardi installations are very common. You can find their installation instructions at this link.

Hopefully you find a qualified person to help you. @sstanczyk might know someone.
