This is a reroof project located in Shoreline, WA where we replaced the roof and rebuilt the chimney from the roof line up. All our chimney crowns are rebar reinforced and are poured with new concrete. Unlike most companies, we do not do the "cut and caulk" method of installing the counter flashing into the chimney. We found this can cause more harm than good. Rather, we have our in-house Mason install new chimney counter flashing and seal with mortar.
