Before the repair

Before repairing an interior leak during snowmelt near the eaves

Do not start with the cosmetic finish

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.

Define the repair question

Ask which layer failed, what trigger activates it, how far the pathway may extend and what evidence will show that the source—not only the visible mark—was addressed.

Preserve a baseline

  • Document roof snow and eave ice from the ground
  • Record attic temperature and visible frost safely
  • Compare affected and unaffected roof sections
  • Keep one dated overview photo and one close view from the same position.
  • Record the trigger state before work begins.

Scope questions worth asking

  • Which competing cause was considered and what evidence weakened it?
  • Which concealed layers may need access and which will remain untouched?
  • How will wet or damaged material be assessed before closure?
  • What comparable post-work condition will be used to verify the result?

Avoid the common shortcut

Do not chip ice with tools that can damage roofing or work beneath falling ice.

Escalation boundary

A roofer and insulation or air-sealing specialist may both be needed because drainage and heat-loss pathways can interact.
