Ice dams and roof leaks in southeastern Wisconsin

Water can back up at a roof edge when snow melts and refreezes. A roof assessment helps investigate the reported leak and relevant roof conditions.

Take photos from the ground and note where interior water appears. Tell the roofer whether the issue occurs during a thaw and whether it has happened before, so the assessment can consider the full history.

If you need help finding the source of a leak or deciding what work to request, ask Dekoven Roofing for a roof assessment.

What ice dams are

Ice dams form when melting snow refreezes at the roof edge and blocks drainage.

Contributing factors

• Heat loss into the attic.
• Poor ventilation.
• Insulation gaps.
• Roof design.

What helps

Addressing attic insulation and ventilation can reduce them. Ask a roofer for an assessment that includes the attic, not only the roof surface.

Safety

Do not chip at ice on a roof yourself, since it is dangerous and can damage shingles.
