Quick Answer
Replace damaged roof flashing for solar when you notice water stains, rust, or mineral deposits around the flashing, indicating a compromised seal. This can be a sign that water is penetrating the roof and reaching the solar panel mount, which can lead to electrical issues or damage to the panels. Typically, this situation arises when flashing is 5-7 years old.
Assessing Damaged Roof Flashing
To determine if your roof flashing is damaged, inspect it visually for signs of wear, such as rust, mineral deposits, or water stains. Check the flashing’s condition, paying attention to its seal around the solar panel mount. For optimal performance, ensure the flashing is securely attached to the roof.
Replacing Damaged Roof Flashing
When replacing damaged roof flashing, use high-quality materials and follow manufacturer instructions. For most solar panel mounts, you’ll need a specialized flashing kit that includes a waterproof seal and a secure attachment mechanism. Apply a bead of sealant along the flashing’s edge and press the flashing firmly into place to create a watertight seal.
Preventing Future Damage
To prevent future damage to your roof flashing, inspect it regularly, ideally every 6-12 months. Check for signs of wear, and address any issues promptly to ensure your solar panels continue to operate efficiently. Additionally, consider using a roof flashing material that’s resistant to degradation from UV exposure and weathering, such as EPDM or TPO.
