What are the bent pieces of metal called that are used to waterproof a house?

The correct terminology for the bent pieces of metal used to waterproof a house is "flashing." Flashing is specifically designed to direct water away from critical areas of a building, such as around chimneys, roof intersections, and window frames. It serves as a protective barrier against water infiltration, ensuring that moisture does not enter the structure and cause damage over time.

Flashing is typically made from materials such as aluminum or galvanized steel, which are selected for their durability and resistance to the elements. Proper installation of flashing is crucial in construction and roofing to maintain the building's envelope and prevent issues like mold growth, wood rot, and structural damage.

The other options refer to different construction elements: brackets are used to support structures, straps might be used for securing components, and joints refer to connections between structural elements. None of these fulfill the specific function of waterproofing that flashing does.
