Common Mistakes People Make with Their Roof in Ontario, Canada

Your roof is one of the most vital parts of your home, shielding you from Ontario’s harsh weather and keeping your property structurally sound. Yet, many homeowners unknowingly make mistakes that can lead to costly repairs, a shorter roof lifespan, or even safety risks. In this blog, we’ll dive into the most common roofing mistakes people in Ontario make and how to avoid them to keep your roof in great shape for years to come.

1. Neglecting Regular Inspections

A big mistake Ontario homeowners make is skipping regular roof inspections. With our wild weather—think heavy snow, ice storms, and summer downpours—it’s easy for small issues like cracked shingles or damaged flashing to go unnoticed until they’re major problems.

Solution: Book a professional roof inspection at least once a year, ideally in the spring or fall, and after big storms like those Lake Ontario squalls. Spotting issues early can save you from pricey repairs later.

2. Ignoring Small Leaks

A little drip in the attic might not seem urgent, but in Ontario’s wet climate, it’s often a sign of trouble—like worn-out shingles or ice dam damage. Ignoring it can lead to water damage, mould growth (and we all know how damp basements get here), or even structural issues.

Solution: Tackle leaks right away. Call a roofing pro to find the cause and fix it before it gets worse. Temporary patches might hold off a rainy Muskoka day, but they’re not a long-term fix.

3. DIY Repairs Without Proper Know-How

With YouTube at our fingertips, it’s tempting to climb up and fix roofing problems yourself. But roofing’s tricky business—especially with Ontario’s steep pitches and icy conditions—and it takes skill, safety gear, and the right materials. A botched DIY job can make things worse or void your warranty.

Solution: Leave big repairs to licensed roofing contractors. If you’re keen on DIY, stick to simple stuff like clearing gutter leaves—and even then, watch your step on that ladder.

4. Choosing Cheap Materials to Save a Buck

When replacing or repairing your roof, going for the cheapest option might feel smart with Ontario’s high cost of living. But low-quality shingles or flashing wear out fast in our freeze-thaw cycles, meaning more repairs sooner than you’d like.

Solution: Invest in quality materials built for Ontario’s climate—like durable asphalt shingles or metal roofing. Spending a bit more upfront saves money (and headaches) over time.

5. Overlooking Gutters and Drainage

Gutters are your roof’s best friend, directing water away from your home and foundation. In Ontario, clogged gutters from fall leaves or ice buildup can cause water to pool, leading to leaks, rot, or damage to your siding—especially during those heavy GTA rainfalls.

Solution: Clean your gutters regularly, especially after autumn in places like Haliburton or a snowy Ottawa winter. Make sure downspouts are clear and push water well away from your foundation.

6. Walking on the Roof Without Care

Whether it’s to shovel snow, clear ice, or hang holiday lights, stepping onto your roof can crack shingles or loosen granules—especially when they’re brittle from a cold Kingston winter.

Solution: Keep roof trips to a minimum. If you must go up, wear soft-soled boots and step lightly near the rafters. Better yet, hire a pro for tasks needing roof access—safety first!

7. Not Prepping for Ontario’s Weather

From blizzards in Sudbury to humid Toronto summers, Ontario’s weather is no joke. A common mistake is picking a roofing system that can’t handle our extremes—like a flat roof in a snowy area or poor ventilation in a hot, muggy region.

Solution: Talk to a roofing expert about materials and designs suited to your part of Ontario. Good ventilation and insulation are musts to fight ice dams and heat buildup.

8. Skipping Ventilation and Insulation Upgrades

In Ontario, poor attic ventilation and insulation can trap heat and moisture, speeding up shingle wear, causing ice dams in winter, or growing mould in humid months. Many homeowners miss these hidden culprits.

Solution: Check that your attic has proper vents (like ridge or soffit vents) and enough insulation. This keeps your roof’s temperature steady and boosts its lifespan through our brutal seasons.

9. Putting Off Roof Replacement

Roofs aren’t forever, and delaying a replacement past its prime is asking for trouble. In Ontario, where wind, snow, and rain take their toll, waiting too long can mean leaks, interior damage, and bigger bills from rot or mould.

Solution: Know your roof’s lifespan (say, 20-30 years for asphalt shingles) and plan ahead. Watch for signs like curling shingles or heavy granule loss—common after a tough Barrie winter.

10. Hiring Dodgy Roofers

Not every roofer knows their stuff, and in Ontario, hiring a fly-by-night crew to save a few dollars can mean sloppy work or no insurance if things go wrong—like a leak during a Niagara spring shower.

Solution: Do your homework. Pick licensed, insured roofers with solid reviews and local experience. Get a few quotes and check references before signing anything.
