Scott,

Thanks for the quick reply. It's kind of a sticky situation as builder is a good friend. I'm just wondering if this is worth digging my heels in over. I agree and don't care about the money... any advice you could offer would be appreciated.

I've read the following sections of UBC that seem to indicate a need for flashing between the brick and hardi siding trim band:

Uniform Building Code Section 1402.2 "Exterior openings exposed to the weather shall be flashed in such a manner as to make them weather proof."

Uniform Building Code Section 1405.3 Flashing.“Flashing shall be installed in such a manner so as to prevent moisture from entering the wall or to redirect it to the exterior. Flashing shall be installed at the perimeters of exterior door and window assemblies, penetrations and terminations of exterior wall assemblies, exterior wall intersections with roofs, chimneys, porches, decks, balconies and similar locations where moisture could enter the wall. Flashing with projecting flanges shall be installed on both sides and the ends of copings, under sills and continuously above projecting wood trim.”

I also read that IRC 703.8 requires flashing wherever 2 dissimilar siding materials meet.

Wouldn't the above code require flashing between the brick and the hardi siding trim (or am I misinterpreting)?

Thanks,

Jay
