About Commercial Roof Flashing
Flashing refers to thin pieces of impervious material expertly installed to prevent water passage into a commercial structure from a joint or as part of a weather-resistant barrier system. In commercial roofing, high-quality flashing is absolutely critical around roof penetrations (like vents, pipes, and HVAC units), edges, skylights, and valleys where water is most likely to seep in. Materials commonly used for durable commercial flashing include aluminum, copper, galvanized steel, or specialized rubberized single-ply compounds designed to match the roof system.
