Choosing the right metal flashing system for a home can be difficult. There are considerations to make to guarantee that the flashing does not corrode prematurely or causes damage to the surrounding shingles. When homeowners choose compatible flashing materials, they will be able to protect their roof from potential moisture damage. One of the most common materials that Fort Worth roofing professionals can install for the roof is lead. This specialized metal is not frequently considered for all types of installations, but it can be ideal in areas where its distinct properties are necessary.
To begin, this material is usually chosen for sections of the roof where a great deal of malleability is required. This means that it will often be chosen for chimney step flashing applications. It can be set up where it is needed without homeowners having to worry about higher installation costs, as this metal can be shaped as needed.
Because of how easy the material is to bend and mold, lead is often chosen for other areas along the roof to create a more specialized installation. It is frequently used along drip edges and between valleys on specialized roofing systems. Its malleability means that it can be set up relatively quickly for more personalized roofing systems without a loss of protection.

Lead is also a very resistant metal. It can resist all types of corrosion and last as long as it is needed on the roofing system. Because of its durability, it is often chosen for coastal homes and polluted environments. These systems can be ideal for helping rooftops weather coastal sea spray damage, as well as acid rain and other corrosive and dangerous environments.
However, homeowners should be sure to treat this metal carefully. Lead is a very soft metal. Because it is so easy to bend and mold into shape, it is also prone to impact damage. This means that homeowners should avoid walking on their roofs where the lead flashing is present. Roofers will need to take special care to avoid damaging the surface of this material as well.
Finally, in order to make sure that the flashings work all year round, it is a good idea to keep them unfastened on one side to allow them to keep up with thermal movements. If the metal is pinned on all of its sides, the flashing can fatigue and tear as it tries to keep up with the effects of thermal shock.
