Ontario Roofing & Home Insurance: What Every Homeowner Needs to Know

Your roof and your insurance policy are more connected than most Ontario homeowners realize. The age, condition, and material of your roof directly affect how much you pay for home insurance, what is covered when something goes wrong, and whether your insurer will even renew your policy.

This guide breaks down the relationship between roofing and insurance in Ontario so you can make informed decisions about both — whether you are planning a roof replacement, dealing with storm damage, or just trying to understand your policy.

How Your Roof Affects Your Insurance Premium

Insurance companies view your roof as one of the most important factors in determining your risk profile. Here is what they look at:

Roof Age

Most Ontario insurers start paying closer attention when your roof reaches 15 to 20 years old. Once a roof passes the 20-year mark, you may face:

• Higher premiums
• Reduced coverage (actual cash value instead of replacement cost)
• A requirement for a professional roof inspection before renewal
• In some cases, non-renewal of your policy until the roof is replaced

If your roof is approaching this age, a professional roof inspection can give you documentation to share with your insurer and help you plan ahead.

Roof Material

The material on your roof influences both your risk and your premium:

• Architectural shingles — Standard coverage at standard rates. This is what most Ontario homes have.
• Impact-resistant shingles (Class 4) — Some insurers offer a discount (typically 5 to 15%) for shingles rated to withstand hail and wind impact.
• Metal roofing — Often qualifies for premium discounts due to superior wind resistance, fire resistance, and longevity. See our metal vs. shingle comparison for more details.
• 3-tab shingles — Standard rates, but their shorter lifespan means you will face the age-related scrutiny sooner.
• Wood shakes — Some insurers charge higher premiums or exclude coverage due to fire risk.

Roof Condition

Visible wear, missing shingles, sagging, or moss growth can all trigger a red flag during an insurer’s property inspection. Keeping your roof well-maintained is not just about avoiding leaks — it is about maintaining your insurance coverage. Our seasonal maintenance checklist covers what to stay on top of.

What Does Home Insurance Actually Cover?

This is where many homeowners get surprised. Here is the general breakdown for Ontario policies:

Typically Covered

• Sudden storm damage — Wind, hail, falling trees, and lightning strikes are generally covered under your dwelling coverage.
• Water damage from storm events — If a storm damages your roof and water enters your home as a result, the interior damage is typically covered.
• Weight of ice and snow — Structural damage caused by ice and snow accumulation is usually covered.

Typically NOT Covered

• Wear and tear — A roof that leaks because it is old and worn out is considered a maintenance issue, not an insurable event. Insurance is for sudden, accidental events.
• Gradual water damage — A slow leak that has been dripping for months is not covered. This is why regular roof inspections matter.
• Neglected maintenance — If the insurer determines that damage was caused by lack of maintenance (clogged gutters leading to ice dams, for example), the claim may be denied.
• Cosmetic hail damage — Some policies exclude “cosmetic damage” from hail — meaning if the shingles are dented but still functional, the insurer may not pay for replacement.

The Grey Areas

• Ice dam damage — This is a frequent point of contention in Ontario. Some policies cover the resulting water damage but not the roof repairs needed to fix the underlying ventilation issue. The ice damming prevention guide explains the root causes.
• Sewer backup — If your gutters and downspouts are connected to the sewer system and a backup causes interior flooding, this may or may not be covered depending on your endorsements.

How to File a Roof Damage Insurance Claim

When storm damage happens, the steps you take in the first 24 to 48 hours matter. Here is the process:

Step 1: Protect Your Property

Take reasonable steps to prevent further damage. This might mean tarping a hole, covering broken skylights, or shutting off water if a pipe was damaged. You are expected to mitigate further damage — and your insurer will cover reasonable mitigation costs.

Step 2: Document Everything

Before touching anything beyond emergency protection:

• Take photos and video of all damage — exterior and interior
• Photograph the overall roof from the ground on all sides
• Document the date and weather event that caused the damage
• Keep receipts for any emergency supplies or temporary repairs
• Write down a timeline of when you noticed the damage and what you did

Step 3: Contact Your Insurance Company

Call your insurer as soon as possible — ideally within 24 to 48 hours. You will need:

• Your policy number
• Date and description of the weather event
• Description and photos of the damage
• Any emergency repair receipts

They will assign a claims adjuster to inspect the damage.

Step 4: Get an Independent Roofing Estimate

Before the adjuster visits, get a written estimate from a reputable local roofer. This gives you an independent assessment to compare against the adjuster’s findings. Our detailed estimate process explains what a proper quote should include.

Important: Do not sign an Assignment of Benefits form or let any contractor take over your insurance claim. Keep control of the process yourself. Our scam protection guide explains why this matters.

Step 5: Meet the Adjuster

The adjuster will inspect the damage. Having your roofer present during this inspection can be helpful — they can point out damage that may not be obvious to a non-roofer and ensure nothing is missed.

Step 6: Review the Settlement

Your insurer will provide a settlement based on the adjuster’s report. Review it carefully and compare it to your independent estimate. If the numbers do not align, you have the right to negotiate or request a re-inspection. You can also hire a public adjuster to advocate on your behalf.

How Roof Upgrades Can Lower Your Premium

Replacing your roof is not just a maintenance expense — it can actively reduce your insurance costs:

• New roof discount — Most insurers reduce premiums when you install a new roof, especially if the old one was over 15 years.
• Material upgrade credit — Upgrading from 3-tab to architectural shingles, or from shingles to metal, may qualify for additional discounts.
• Impact-resistant shingle discount — Class 4 impact-resistant shingles can earn a specific discount from many Ontario insurers.
• Improved wind rating — Metal roofing and properly installed architectural shingles with enhanced wind warranties can lower your wind-damage risk profile.

Use our roof cost calculator to estimate the cost of an upgrade, and ask your insurer what premium reduction a new roof would earn.

Common Questions About Roofing and Insurance in Ontario

Will my premium go up if I file a claim? It depends on your insurer and claims history. A single weather-related claim typically has less impact than multiple claims within a few years. Some insurers offer “claims forgiveness” for first-time claims.

Can my insurer cancel my policy because of my roof? Yes. If your roof is deemed too old or in poor condition, your insurer can decline to renew your policy. This is becoming more common in Ontario, particularly for roofs over 25 years old.

Should I replace my roof before selling my home? From an insurance perspective, a newer roof makes your home easier and cheaper to insure, which is a selling point for buyers. From a resale value perspective, it is one of the highest-ROI home improvements. See our cost guide for the full analysis.

Does my condo corporation’s insurance cover my roof? If you are in a condo townhome, the corporation’s master policy may cover the roof structure. Check your condo documents and your individual unit policy for specifics.
