First, you need to play detective. Grab a flashlight on a rainy day and look up—from the attic. You’ll likely find the leak isn’t a hole, but a failed seal around a screw or a pipe boot. Screws are the number one culprit—their rubber gaskets get brittle and crack after a few summers of scorching heat.
Another prime suspect? Flashing. Those metal strips where the roof meets a wall or chimney? They’re like the architectural armpit of your house—prone to sweating and, well, leakage. Don’t ignore the ridges between panels either; sometimes water sneaks up and over a poorly seated seam.
