Common leak points
- Parapet caps and corners
- Drains and scuppers frozen or clogged
- Skylights and flues
- Low spots where slush sits
- Edges where wind has lifted the coating
Snowmelt leaks
Snow drifts against parapets and melts slowly. Water gets into cracks, freezes and widens them. Leaks that appear days after a storm usually start this way. See snow and cold.

The repair

Common questions
Can you repair in winter?
Often on a dry, mild day. Full recoats may need to wait.
Why does it only leak after snow?
Freeze-thaw cycles open cracks that rain alone doesn't reach.
