Wanted - Help with Leaded Copper

[PBARNHART]

Roof coatings included lead, 60/40 all the way up to pure tin.
You need an agressive flux and you then have to "kill" it too.

You could take a large iron and coat your own copper with solder. Although it won't have the same patina.

Consider having the customer sign some sort of document that they are aware of the lead on their roof, that you are fixing it not putting the lead on the roof. The plater that I just visited mentioned that Lead is more like the black plaque. Keep yourself out of the law suits.
Just a thought.

Jeremy, and all the ships at sea;(Pam) have you ever tryed brazing (oxy-acet) with a stick of sillfos. Used in refrigeration copper lines for copper and brass. No flux needed. ......Duck

I would think that temps as high as brazing would increase the likelyhood of setting something on fire with respect to working on roofs!
