Chimney leak log for snow, ice and rain
Record what you see from inside, keep the moisture path apart from guesses about the cause, and stay off the roof.
Leak log
Take each photo from the same safe indoor position. A series shows the path more clearly than a single close-up.
| Date | Weather | Where it appeared | How long | Photo spot |
|---|---|---|---|---|
Ask for a labeled assessment
Ask which observations support the proposed cause.
- Roof connection
- Flashing
- Masonry
- Crown
- Cap
- Chase enclosure, if there is one
Compare solutions to findings
- Each repair is tied to a documented finding
- How the result will be checked
- What stays outside the scope
When freeze-thaw is part of the picture
Moisture exposure and repeated freezing can contribute to masonry deterioration. Visible damage deserves a site-specific assessment; the weather alone does not diagnose the repair.
Stay off the roof
Record from inside the house or from the ground. Do not climb onto the roof, and do not stand under hanging ice or loose masonry to take a closer photograph.
About this log
The log records what you see and when. It keeps the path the moisture takes apart from any guess about which part failed, and it never asks you to go onto the roof.
