Jim,

I was thinking that the following "general requirement" would apply here:

"A water-resistive barrier is required in accordance with local building code requirements. The water-resistive barrier must be appropriately
installed with penetration and junction flashings in accordance with local building code requirements. Flashing is required over horizontal
protruding and exposed trim. James Hardie will assume no responsibility for water infiltration."

Am I reading this correctly?

Thanks,

Jay
