Jim Baird Posted February 19, 2017 Report Share Posted February 19, 2017 How big or how tall? I like the vertical distance to the window sill. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted February 19, 2017 Report Share Posted February 19, 2017 Are there any written standards as to how big a header flashing should be at a wall to roof detail? I think that the correct term is apron flashing or base flashing. Certainteed requires a minimum 2" vertical leg and a 3" or 4" horizontal leg, depending on the location.

Steven Hockstein Posted February 20, 2017 Report Share Posted February 20, 2017 James Hardie requires a 2" gap but I rarely see it because it looks bad. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted February 21, 2017 Report Share Posted February 21, 2017 If it's done neatly, AND the flashing color matches either the roof or the siding it's barely even noticeable. Quote Link to comment Share on other sites More sharing options...
