   I can't say that I've ever seen it soldered (though usually the flashing around here is galv or aluminum).

   I'm sure that someone somewhere solders it, though.

   Soldered copper for flashing

   Using soldered copper is the traditional approach. Flash it using sheet copper and traditional soldering methods.  Today most of them prefer lead to flash their chimneys since easy to work with. Copper is long lasting compared to lead but in coastal areas copper will wear out soon. A skilled tinsmith can easily do the soldering copper procedure. Its simple, chemically clean the metal, with flux, the parts to be sodlered should be in firm contact with each other with weights or clamping. Use the 65-35 tin-lead alloy and the iron tip should be tinnes.melt solder and solder continuously. clean flux using warm water.

   It is these flashes which would ensure waterproof roofs. Proper flashing around chimney includes two layers , step flashing and counter flashing.  Always check for any leakes around these corners. Check for this article on 5 signs your chimney needs a repair (http://www.royalyorkroofing.ca/blog/chimney-repair/5-signs-your-chimney-needs-a-repair/). Industrial roofing companies prefer copper since it is the best long living option though expensive. Small cracks can be sealed with caulk designed to repair masonry.  Usually for silicone based sealers for water proofing a garden sprayer would do the job.

   also ensure counter flashing applied to the masonary wall to shed water off the wall and to the roof

   What was wrong with the old copper ? 

   A 5 gal bucket of fiber cement works OK too <G>

   Just to clarify

   While there's a place for roof goop, solving a leak problem around flashing isn't one of them.
