We are having a copper roof put on our new addition, which is attatched to our 1829 brick Federal house. Is step flashing the proper flashing technique? Or is just a single, continuous strip of flashing also an appropriate alternative?

Not enough detail here, Brenda, but step flashing means step shingles...as in a shingle roof. Don't you trust the copper man?
*Thanks for the response Lonecat. Maybe I'm having a terminology problem. I'll try to be more specific. We have a copper roof on our old house that was put on about 4 years ago. On the porch roof, where the roof meets the wall, there is a series of individually cut pieces of copper that step-up the roof ( resembling stair steps), and the grout between the bricks on the wall appear to be raked out to accept the turned (90 degree) upper edge of the step flashing. It is the same flashing system I see on all the old houses with standing seam roofs in our area. Does this make any sense, am I just using the wrong terminology? And what I'm wondering, is this method the standard of excellence, and would any other method be a shortcut?
*Is this a descending roof line next to a brick wall? Is he removing the mortar and putting the flashing between the bricks? If so I don't see how a single piece of flash could work, stepping it is the only way to do it. As lonecat sez "Don't you trust your roofer?" Without a picture, we're just guessing. Joe H
*I was writing, you were posting. Yup, that's how it's done. So, is he doing something different? Joe H
*b WBA AtYour ServiceStep flashing is indeed used on a shingle roof and not on a standing seam roof. The term you are looking for is counterflashing. The stepped counterflashing laid into the mortar joints is widely accepted as the finest way to flash. In recent years it has become popular to use a diamond blade in a grinder and cut a reglet (a kerf or slot) into the brick on a slope which parallels the roof pitch. This way the brick can be laid ahead of time with no layout for flashing installation. Personally, I prefer the look of the steps and the integrity of my bricks without sawcuts.
