thank you man. that's a huge compliment, especially coming from you.You did a beautiful job.
Did you install new mortar or a good caulking sealant inside the reglette joint prior to inserting the top copper hem into the joint?
You can also apply a bead of caulk to the exterior of the sheet metal to double the water migration protection and use a wet finger to shape it and trowel it in place nice and smooth and cantilevered to shed water.
i haven't sealed it in yet. right now they're held in place with little rolled up pieces of copper and kind of shimmed/jammed into the groove.
i've been trying to figure out if i should apply mortar over the groove, or just silicone; i guess i'll do the silicone based on what you just told me.
thanks a lot.
