Inspection Checklist for Attic Insulation
When Ontario weather changes quickly, roof details are tested by water, wind, snow, ice, and heat. This page focuses on attic insulation 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 where thermal performance affects snow melt, comfort, and roof temperature. Homeowners should pay attention to R-value, air sealing, eave clearance, and moisture behavior 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.
