Quick Answer
Inspecting the flashing integrity on solar installations requires visual inspections and a series of tests to ensure the system's integrity and prevent leaks. This process involves checking the roof's condition, sealants, and connections for any signs of damage or degradation.
Visual Inspection
A thorough visual inspection should be conducted on the solar installation, focusing on the flashing around the edges of the panels, where connections are made to the roof. Look for signs of wear, cracking, or deterioration of sealants and flashing materials. Check for any gaps or openings that could allow water to penetrate the system. During the inspection, note any damaged or missing flashing components, such as roof penetrations, edge seals, or roof-to-wall flashing.
Testing and Evaluation
To further evaluate the flashing integrity, perform a series of tests, including a water leak test and a pressure test. Use a hose to simulate rainfall and apply a moderate amount of pressure (approximately 10-15 psi) to the flashing and sealants. Observe the system for any signs of water intrusion or leaks. Additionally, inspect the flashing and sealants under UV light to detect any signs of degradation or cracking.
Documentation and Maintenance
After conducting the inspection and tests, document the findings and create a maintenance schedule to address any identified issues. Schedule regular inspections (at least annually) to monitor the flashing integrity and perform necessary repairs or replacements. Consider using data loggers to monitor the system’s performance and detect potential issues before they become major problems.
