The metal things on roofs are commonly referred to as flashing. Flashing is essential for waterproofing the roof, especially around discontinuities or objects protruding from the roof like chimneys, vents, or pipes. It's made from materials such as aluminum, copper, or galvanized steel and serves to direct water away from certain areas to prevent leaks. Properly installed flashing is critical in maintaining the integrity and longevity of a roof by ensuring it remains leak-free.
