Deck flashing, a process that prevents water from seeping into your home's siding and framing, is a critical component of deck construction and maintenance. Flashing is a layer of waterproof material that keeps water from getting into places it doesn't belong, such as your home's siding and framing, as well as wood and metal building materials that hold a deck together. Without flashing, a deck can rot and decay, leading to a weakened deck foundation, dangerous conditions, and expensive repairs.
Many materials, including aluminum, copper, lead, steel, and PVC, can be used as flashing. Areas that experience high winds and heavy rain should receive enhanced flashing techniques to further protect against wood dry rot and corrosion of connectors, which could lead to deck collapse. Homeowners should never rely on sealant as a proper substitute for flashing.
