Details: Nail-Flange Flashing

According to the Stucco Manufacturers Association, the stucco industry has always maintained that one should anticipate incidental moisture to find its way behind the cement stucco membrane. The underlying water-resistant barrier (building paper or housewrap) should be integrated in a “shingle-fashion” with the nail-flange and flashings. This proven practice prevents water entry, meets code requirements and directs water down to exit at the base of the wall.
