Chimney Crickets and Water Management
A chimney on a sloped roof interrupts water flow. On wider chimneys, a cricket or saddle can divert water around the upslope side and reduce the chance of pooling and leaks.
A chimney cricket is a small peaked structure behind a chimney that splits and redirects water. Not every chimney requires one, but a broad or poorly drained chimney intersection deserves a close inspection.
What to look for
Signs of trouble include staining near the chimney, damaged flashing, debris buildup, moss on the upslope side, and recurring leaks after wind-driven rain. Interior staining may appear far from the masonry because water follows framing.
A repair may involve reworking step and counterflashing, rebuilding the cricket, correcting the roof plane, or addressing masonry joints. The scope should explain which component is failing instead of calling the entire chimney 'the problem.'
What to do next
Use the checklist below to make the next conversation specific. If the condition is active, unsafe, or connected to a storm, move the inspection up the calendar.
Keep the next step concrete.
- ✓When replacing a roof, chimney details deserve a dedicated line item and photographs. They are too important to disappear inside a generic flashing allowance.
- ✓Record the date, roof area, and weather or symptom that prompted the question.
- ✓Keep photos, invoices, and written recommendations with the roof file.
- ✓Ask when the issue needs professional roof access instead of ground-level monitoring.

A roof inspection can determine whether the cricket is missing, undersized, blocked, or unrelated to the leak.
