Given that you're in Louisiana it's critical to thoroughly inspect the plywood sheathing and replace any rotted sections or sections contaminated with mold or infested with termites.
The Masonite will conceal areas that should be replaced and trap mold, rot and moisture.
It's a poor way to save money. Have all the Masonite removed.
Have all the old Masonite removed.
You might go to the Hardie website and review the warranty.
It's an excellent warranty, but the product needs to be installed correctly for Hardie to honor it.
Have I answered your questions?
