Is there a “cap” design for a mansard condition using the flat profile concrete roof tile?
The easiest way to cap a mansard application is with a metal cap unless the wall is narrow enough to be fully covered by one of our standard ridge tiles. Please see attached drawing. Q: What would you recommend in lieu of copper flashings at roof in a marine exposure environment? Vinyl flashing, aluminum (I believe this corrodes against pressure treated lumber), GSM (pitting occurs), or other material? And for what conditions? A: If your project is situated within 1500 feet of the shoreline, you should stick with copper or stainless steel for your exposed flashings. If you are further than that, you could probably use a Zinc-Alum or Galv-Alum material for your flashings and save quite a lot of money without sacrificing too much corrosion resistance.
