Common Causes Explained for Ice Dams
Ontario homeowners often notice roofing problems only after a leak appears inside the home. This page explains how ice dams works, what can go wrong, and how to think about the issue before requesting a roofing estimate or quote.
Common Causes Explained
The key is to look at water movement, airflow, fastening, material condition, and the way each detail connects to the roof deck. Small errors in these areas can create repeated service calls.
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.
