- Check for flashing failures around vents, chimneys, and seams, as these are common weak points where leaks can develop.
- Inspect the roofing membrane for punctures or tears that may have occurred due to weathering or improper installation.
- Evaluate drainage issues, such as clogged drains or insufficient slope, which can cause water pooling and increase the risk of leaks.
- Look for visible signs of damage on the ceiling, including discoloration or sagging, to help pinpoint the leak’s source.
