Flashing is a thin piece of metal applied to the building’s exterior to protect against water damage. It covers seams between exterior surfaces like the roofline, chimney, gutters, window sills, and other openings. Damaged flashing is a common issue among homeowners. It can lead to water infiltration and costly damage to the interior of your home.
1. Warped, Bowed, or Out-of-Plumb Flashing
Flashing should be installed correctly and in alignment with the building. You can observe this by simply inspecting the building’s exterior. If the flashing is warped, it should be replaced immediately. This may be a sign of an improperly installed flashing system or an issue with your roof. A warped flashing may not protect your home from water damage as it should. This condition can be remedied by flashing replacement or repairing it, depending on the severity of the damage. A professional can properly diagnose and resolve any underlying condition that caused the damage.
2. Cracked Flashing
During the installation process, flashing is specifically mated to roofing materials. Over time, a crack can develop and separate these elements of your roof system. The gap created by the crack allows water to seep into your home’s structure. When you notice cracks in the flashing, correct them immediately. A small crack can be repaired by matching the size and shape of a replacement piece and fastening it to the old flashing material with corrosion-resistant screws. If the crack is larger, replace the piece of flashing rather than attempting to repair it.
3. Severe Corrosion
Flashing is susceptible to corrosion, causing a loss of strength and integrity as the building ages. This can lead to penetrating water damage as the flashing weakens over time. Take special precautions with flashing that shows signs of severe corrosion, such as replacing it or applying a protective coating. If your flashing hasn’t been replaced for some time, you should check it for signs of distress. Look out for paint peeling away from the flashing and signs of rust, such as a brown tint to the metal.
Regularly inspect the condition of your building’s exterior and take corrective actions where necessary to ensure your home is adequately protected. Pay careful attention to the flashing. If you notice signs of damage or corrosion, contact a professional roofing company for a thorough inspection and expert advice.
