I live in MN where the builder used BuildRite (house new as of 2001) instead of OSB, they used a fiber board to cover the outside of the house (under the vinyl). I’m about to attach my header board and wanted to know if I need to remove the fiberboard to attach the header directly to the house foundation rim wood directly. I’m worried that the fiberboard will compact if I put the header over it.

I can provide pictures later if necessary.
