Lead flashing is an essential component of your roofing system, designed to prevent water from seeping into your home where your chimney and roof meet. However, sometimes leaks can occur due to a variety of reasons. The most common cause is improper installation of the flashing, which can lead to gaps that allow water to penetrate. In addition, severe storms can damage the flashing, causing it to pull away from the roof and create openings for water to enter. Over time, the sealant used to secure the flashing can also deteriorate, compromising the watertight seal and allowing leaks to occur. It is important to identify and repair any leaks promptly to prevent water damage to your home.
