Inspection Checklist for Snow Load
When Ontario weather changes quickly, roof details are tested by water, wind, snow, ice, and heat. This page focuses on snow load and why it matters for long-term roof performance.
Inspection Checklist
Homeowners should look for visible changes, interior stains, attic moisture, loose materials, blocked drainage, or areas where previous repairs appear to rely only on sealant.
This topic matters because when accumulated snow adds weight and changes drainage behavior. Homeowners should pay attention to structure, drift areas, ice, attic heat, and spring melt 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.
