Planning on having a complete, properly-sealed, and void-free building envelope? Even if everything is perfectly planned and executed, your barrier will still end up with giant holes we more commonly refer to as doors and windows. This is where flashing becomes necessary to properly seal around these unavoidable barrier disruptions to prevent wood rot, mold, structural damage, or insect infestation. Flashing is a thin layer of waterproofing that eliminates upward-facing seams, crevices, gaps, or spaces where moisture could collect and seep past the barrier. Proper flashing ensures a seamless, shingled waterproofing surface that will not interfere with the force of…
