Sidewall flashing strip – a finishing element for chimneys, parapets, and vertical roof components. Part of the sidewall flashings group. Made of galvanized metal sheet covered with a protective coating. Various coatings available.
Sidewall flashing, also known as wall-to-roof flashing, is a technical solution used where the roof meets vertical building elements, such as walls, chimneys, or parapets. Its purpose is to seal these joints and prevent water from entering the structure. Wall-to-roof flashings typically consist of two parts: the lower flash (installed on the roof surface, where it meets the wall) and the upper flash (attached to the wall or chimney, often covered by a pressure strip). The entire assembly is sealed with silicone or special roofing tape, which ensures complete watertightness. They are most often made of galvanized sheet metal coated with protective coatings that can even double its corrosion resistance.
A counter-flashing strip is a sidewall flashing that belongs to the group of sidewall flashings. Installed together with sidewall flashing, it helps ensure maximum watertightness and proper alignment of the roof coverings around chimneys and parapets. Additionally, to protect vertical surfaces (walls) against water seepage, we encourage you to familiarize yourself with the other components of the wall flashing kit:
