On the market today, lead flashing is considered a durable weatherproofing material for use in construction and roofing projects. Its inherently malleable and flexible nature makes it easy to use and suitable for a diverse number of roof types. As lead is a non-ferrous and non-reactive metal, it is naturally resistant to corrosion and will not rust. From an aesthetic point of view, its muted, silver -grey finish complements a variety of building materials such as glass, concrete, and brick. These same weather resistant benefits of lead, along with its density, also make it a compact and resilient option for counterweights on heavy construction equipment. Lead because of its density, is also used as the filler in pile driver hammers.
