Has anyone worked with lead coated copper for flat roof aplications.
I.m working on and estimate for a real nice portico entryway and the plans call for 20oz flat seam lead coated copper. Ive never worked with the stuff so i’m not sure what to do with it and how to work with it.
the roof has a very low slope. this is no way to change the slop of the roof because there is a window about 14″ about where the door is.
Any suggestions??
Thanks

Works about the same as regular copper.
When soldering it helps to run a wire wheel chucked in a drill across the seam first.
What ya got for torch and /or irons?
Gallon of Ruby fluid is in yer future too.

I don't have a solder iron yet. just have not needed one til now.
I recently spoke with a metal fabricator who is pricing a zinc coated copper roof for me. Iwould however like some more tips as to what to do if the fabrication thing seems too expensive for the customer. Ive never had to do a roof that required such a material before and can probably us all the help i can get.
do I know how to solder regular copper pipe ? yes (just in case you needed to know.
How about a brake to bend the material? For small pans, a hand slot bender might also work.
To do large amounts of pre-tinning, you really need a trough of molten solder. Dip each edge first in the ruby fluid, then in the solder. Doing it by hand with heated coppers will take forever, and turn out uneven tinning and warped edges. I tried that on my valley locking strips, never again.

What is ruby fluid? and why do I need it?

Yes - I've done quite a bit of LCC flat seam work. You should use 60/40 solder on it since the lead coating makes the solder lead rich and too soft if you use 50/50.
Pre-tin your pans before you bend them. 20 oz is harder to sweat than 16 oz.
You need 5 lb soldering coppers to sweat it properly.
edit: Ruby Fluid is a flux brand name.
I think I'd ignore the wire brush advice unless you get your work wet after fluxing.
Wear gloves and don't eat, drink or smoke 'til you've washed your hands thoroughly. When you get home, change your clothes before letting your kid climb up in your lap.
