Tracing a leak back to its source

Water rarely drips straight down from the hole in a roof; it runs along the decking and framing first. Tracing a leak means working from the stain back uphill to the likely entry points.

From the reference

Finding a leak is not a search. It is a process of elimination run in a specific order, and the order matters more than the eyesight. Almost everyone starts at the roof directly above the stain, and almost everyone is looking at the wrong part of the roof.

What follows is the procedure a roofer runs on a leak call: establish when it leaks before you establish where, get into the attic while it is still wet, rule out condensation, then work the exterior in the order the failures actually occur.
