Ice Management and De-Icing
Ice dams damage Ontario homes every winter, causing water infiltration that can saturate insulation, stain and damage drywall, and in severe cases promote mold growth. Understanding how your home insurance handles this damage is important before you face a claim.
Standard home insurance policies in Ontario typically cover sudden, accidental water damage — including water that enters through roof damage caused by ice dams. However, policies vary significantly in how they define covered versus excluded damage.
Best Practices for Ontario Winters
What's typically covered: water damage to interior ceilings, walls, and flooring resulting from ice dam water infiltration. Removal of the ice dam to stop ongoing water entry. Repairs to damaged shingles or roofing materials directly damaged by the ice.
What's often excluded: damage resulting from a 'lack of maintenance' — if the ice dam formed because of consistently inadequate attic insulation, insurers may argue the damage resulted from a maintenance failure. Repeated ice dam damage without remediation may also be excluded.
Professional Snow and Ice Control
How to strengthen a claim: document the water damage with photos as soon as you discover it. Have the ice dam professionally removed to stop ongoing damage (keep the invoice). Hire a restoration company for interior drying and repairs. Don't delay — ongoing moisture damage can be excluded as 'failure to mitigate.'
Preventive investment reduces claim risk: adding attic insulation and air sealing (typically $1,500-5,000) eliminates the root cause of ice dams. Some insurance companies offer premium discounts for documented home improvements that reduce risk.
