Finding a roof leak: where the water is really coming from
The stain on your ceiling is where the water landed, not where it got in: water runs along the roof boards and rafters first, so the real entry point is usually higher up, at a pipe boot, flashing, a valley or a skylight. Look from the attic and the ground, never from a wet or icy roof, and in a Calgary winter rule out melting attic frost first, because it looks exactly like a leak.
