  • lead burning joints on box gutter

    Hello,

    I am a carpenter who has decided to do the flashing on a conservatory I have built.

    I have been advised by a builder to simply lead-mastic all joints in the box gutter for expansion/contraction and also I suspect because he thinks I'll screw up any lead burning. However, I am determined to learn this skill and shall hole myself up in the workshop for a few days to practice!

    If anyone has any advice on this task I would really appreciate it.

    I shall be working at the top of a ladder and was hoping to use a small hand held gas burner. Would this be adequate?

    For the actual joints - I thought overlapping carefully scraped and brushed lead then sandwiching a thin strip of lead in between would be appropriate. After heating it could be pressed to seal the joint. Lead solder has been suggested on another forum because it melts at a lower temperature than the lead sheet. Would this be a good idea or will the joint be too weak?

    Your help is much appreciated,

      A bit hard to describe without illustration, but a couple of methods I use.

      First would be to try and prefabricate any thing you can, beats working atop a ladder.

      Lead can be "brazed"using low low heat and lead strip as filler.

      You can also "solder" using a soldering iron and lead as solder.

      Any good "Mastic" or Roofers Silicon will seal between two sheets of Lead.

        do you know that here in the states we cant use lead.

        I'm not 100 percent sure about using it for gutters ?

          i did watch someone solder a gutter together and they used a electric soldering iron to do it . using this you will not burn the copper ,i do not know what a low heat will do to the copper .

            We can use lead in California for DWV systems. I still us lead-in closet rings. If I remember right Utah and Rick both agreed that they prefer them.

            I know Utah did, if you did not, please correct me Rick.

              you're right. i prefer the caulked on rings. (lead).

              i believe that non potable systems can still use lead based solder. ie, lawn sprinkler systems and pools. but then again you don't see too much of this done in copper anymore.
