House was built in 2008 and has real stone veneer on part of the home. There are no readily-visible drainiage provisions as you would find with brick. Using the 2000 IRC R703.7, it states that “All stone and masonry veneer shall be installed in accordance with this chapter, Table R703.4 and Figure R703.7…”
Looking at figure R703.7, it clearly shows weepholes. And, R703.7.6 (located in “this chapter”) states necessity of weepholes.
Local code enforcement states weeps are necessary on stone veneer. I got mixed answers from other contractors and home inspectors.
Now, this house is a new construction foreclosure. Bank took it over and a contractor was assigned to make repairs from my report. Contractor stated that the stone manufacturer said specific weeps are not necessary when gaps are intentionally left in the mortar between stones as gaps serve as weeps. That makes sense to some degree and mortar is not real tight on this home; gaps present in random places.
However, weeps are supposed to be placed immediately above the flashing. So, I would think I would see a horizontal line in the stone where the bottom of stone, and mortar gaps, would serve as weeps (make sense?) I don’t see any planned break or purposeful patten to the stone where the flashing would be.
What do you think?
