Inspection Checklist for Ice Dams
When Ontario weather changes quickly, roof details are tested by water, wind, snow, ice, and heat. This page focuses on ice dams and why it matters for long-term roof performance.
Inspection Checklist
The strongest roofing decisions come from understanding the whole assembly: deck condition, underlayment, flashing, ventilation, fasteners, drainage, and installation workmanship.
This topic matters because along cold eaves when melting snow refreezes and traps water. Homeowners should pay attention to heat loss, attic bypasses, insulation, underlayment, and drainage when reviewing roof condition or comparing roofing quotes.
What Homeowners Should Check
Start with the visible roof area, then check the attic if it is safe and accessible. Look for staining, soft decking, blocked airflow, loose materials, rust, cracking, lifted edges, or signs that water is moving behind the surface layer.
Before approving any roof work, homeowners should ask how the contractor plans to address the cause, not only the surface symptom.
