Roof repair — Ontario context

Severe weather events are the leading cause of property insurance claims in Ontario, with wind and hail damage a significant share of residential roofing claims.

Insurance Bureau of Canada, Facts of the P&C Insurance Industry, 2024

Unrepaired roof penetrations or missing shingles can allow infiltration that causes structural damage within 1–2 seasons — often at 10× the initial repair cost.

CMHC, Homeowner’s Guide to Understanding Your Roof

Roughly 40–50% of roof leaks in Ontario homes originate at flashing failure points — not shingle failure — making accurate diagnosis critical.

Common repair scenarios

Missing or damaged shingles

Spring and fall windstorms across Central and Northern Ontario frequently blow off shingles at ridge lines and exposed edges. Exposed decking must be addressed within 24–48 hours in wet conditions.

Storm & impact damage

We respond throughout our service area with emergency stabilization, complete damage documentation and insurance-ready reports for all storm-related claims.

Flashing & valley failure

Most leaks trace to transition points. We reflash chimneys, vents and wall intersections and clear valleys so water runs where it should.

Repair or replace — our honest framework

If your roof is…	Our recommendation
Under 15 years old, isolated damage	Targeted repair — almost always the right call
15–20 years old, localized damage	Repair with a wider condition assessment
20+ years old, multiple failure points	Replacement — repair cost approaches replacement
20+ years old, one area damaged	Honest assessment — depends on overall shingle condition
Under 10 years old, recurring leaks	Investigate installation quality; potential warranty claim

Frequently asked questions

How quickly can MKT respond to an emergency repair?

For active leaks and storm damage, call (705) 279-1774 directly. We prioritize emergencies and provide same-day response where safe access is possible.

Can you repair a roof in winter or rain?

Some repairs are possible in cold or light rain using appropriate materials and technique. Active storm conditions require waiting — we advise on timing and temporary protection when needed.

How do I know if storm damage is covered by insurance?

Wind, hail and falling-tree damage are typically covered; wear and tear is not. We provide detailed documentation to support your claim and work with your adjuster.

What are the most common causes of roof leaks in Ontario?

Flashing failure at penetrations (40–50% of cases), missing or cracked shingles, ice-dam water infiltration, and valley failures from debris accumulation.
