Field guides

Reading an interior leak during snowmelt near the eaves
Eave leaks during snow conditions can reflect ice-dam backup, flashing defects or attic heat loss. The ice is often a symptom of heat and airflow conditions as well as drainage.
Reading water marks below a roof valley
Valleys concentrate runoff. Debris, ice, damaged underlayment or an undersized drainage path can produce leakage that appears well below the valley line.
Reading a ceiling stain that appears after wind-driven rain
A stain that follows a particular wind direction can reflect rain entry at a roof edge, flashing joint or wall-to-roof transition, but the visible mark may be far from the entry point.
Reading a roof leak that appears hours after rain
A long delay does not rule out roof entry. Water may be stored in insulation, sheathing laps or cavities before reaching the finish.
Reading a skylight drip that begins during thaw
A skylight that drips during warming weather may involve exterior leakage, snowmelt, condensation on cold components or blocked drainage paths.
Reading a stain near a chimney after rain
Water near a chimney may enter at step flashing, counterflashing, masonry joints, the cap or an upslope roof defect. The nearest visible component is not automatically the source.
Reading an exterior wall stain below a gutter
A wall stain below a gutter can result from overflow, overshoot, a leaking joint, blocked outlet or water running behind the gutter rather than through it.
