This makes lead flashing a cost-effective option, as it eliminates the need for frequent replacements and repairs.

In addition to its longevity, lead flashing is highly resistant to weather elements. It can withstand extreme temperatures, from scorching summers to freezing winters, without cracking or warping. Lead is also impervious to UV rays, preventing it from fading or deteriorating under the sun's harsh rays. Furthermore, lead flashing is resistant to moisture, preventing leaks and water damage in the roof.

To further illustrate the benefits of lead flashing, here is a table showcasing its longevity and weather resistance compared to other common types of flashing materials:

Flashing Material Longevity Weather Resistance
Lead Excellent Excellent
Copper Good Good
Aluminum Average Average
Galvanized Steel Fair Fair
PVC Poor Poor

As shown in the table, lead flashing excels in both longevity and weather resistance compared to other materials commonly used for roof flashing. Its exceptional durability and ability to withstand various weather conditions make it an excellent choice for shingle roofs.
