I'm going to install a soldered seam terne coated roof using follansbee TCSII, and would like to use 100% tin solder instead of 50-50. Anyone out there used this stuff before? Are the techniques the same as for copper with 50-50 solder? I have 26 gauge 10x3 sheets available locally and was planning to sheer into 18x24" pans. Is this stuff workable on a portable sheet metal brake? I have an express soldering unit that I have been familiarizing myself with and have just put up copper gutters but have never attempted a flat roof before. I've read Joe's chapter on the subject and was planning to use this method of construction . I know TCS is tougher to work with than the 16oz I've used elsewhere on my house, can somebody offer any words of advice before I embark on this journey? Some questions I have are : should I pre-tin?; would it be best to use a shop brake; any advice on soldering with tin solder or with TCSII; can drip edge be nailed; any tools that would make the process easier( I have snips and soldering unit only); any allowances for expansion , etc,etc.

The tin solder is similar to the 50/50 solder. You should have no problems with it. By portable sheet metal brake, do you mean an aluminium brake? Or do you mean a heavy steel brake that you can throw in the back of your truck? You should make up the pans on a steel brake. Some say to clean the solder joints with laquer thinner before soldering. Pre-tinning is helpful on vertical joints or other sloped surfaces where soldering is more difficult. Remember to flux. Call Follansbee for tips on soldering TCSII.
