Chatham-Kent’s flat topography and location along Lake St. Clair and the Thames River make overland and basement flooding key environmental insurance considerations. Severe weather in Southwestern Ontario can lead to significant wind and roof-related exposures as well.
This page displays Chatham well above Ontario’s median and shows the difference between the two local areas. It also compares rates by home size, year of construction and roof age.

How Home Insurance Coverage Works in Chatham
In the typical house depicted by our Chatham sample, approximately 85% of the premium covers basic coverage and 15% goes toward the increased water coverage.
Properties vary greatly in their degree of risk due to low elevation, river inundation and/or erosion, so address-specific assessments should be conducted. Be sure to check your insurance to see if and to what extent it covers overland floods, sewer backups, groundwater, erosion, etc. or excludes them.
| Coverage Type | What’s Included? | Median Annual Home Insurance Premium |
|---|---|---|
| Base Residence / Dwelling (Core Policy) | Dwelling and detached structures; personal effects; additional living expenses; personal liability; and insured risks under a comprehensive policy. | $2,324 |
| Enhanced Water Protection (Separately Priced) | Sewer-backup, overland-water, groundwater or enhanced-water coverage offered by certain insurance companies. | $407 |
| Coverage Total | MyChoice standard home profile | $2,731 |
*A comprehensive policy typically covers the structure itself as well as personal property against all risks, unless they are excluded. This might include losses from fire or smoke, wind, hail, lightning, falling objects, vandalism, theft, certain kinds of water damage, etc. Coverage is subject to policy conditions, exclusions, deductibles and limits.
What Chatham Homeowners Should Check
To understand how a Chatham policy would respond to water damage, confirm:
- which of sewer backup, overland water and groundwater are actually insured.
- how combined limits apply when more than one type of water enters the home.
- whether a percentage or fixed-dollar deductible applies to water damage.
- which exclusions apply to groundwater, repeated leakage or unrepaired damage.
- whether basement features, foundation type or prior losses affect eligibility.
In Chatham, when storms and flooding are a possibility, knowing what your policy covers may be just as important as the limit of coverage you choose.
Do Older Roofs Cost More to Insure in Chatham?
Ask how they pay out on hail/wind damage, depreciation, inspection requirements, etc. Roofs more than 20 years old cost $609 more than those in the youngest age group.
| Roof Age | Median Annual Home Insurance Premium |
|---|---|
| 0–5 yrs | $2,411 |
| 6–10 yrs | $2,570 |
| 11–20 yrs | $2,731 |
| 21+ yrs | $3,020 |
