Common Roofing Myths That Could Cost You Big

When it comes to roofing, misinformation is more common than you’d think—and unfortunately, believing a myth can cost you a lot of money, time, and stress. Whether you're a homeowner, a property manager, or a business owner in Edmonton, knowing the truth about roofing can make a big difference in how you maintain and protect your investment.

At J & D Independent Roofing Inc., we’ve spent over 30 years helping Edmontonians separate fact from fiction. With decades of hands-on experience and a specialty in flat roofs, our team has seen the impact that bad roofing advice can have. So today, we’re setting the record straight.

Here are the most common roofing myths—and the costly consequences of believing them.

Myth #1: Flat Roofs Always Leak

The Truth:

Flat roofs have an unfair reputation. While early designs may have had issues with drainage and water pooling, modern flat roofing systems are incredibly effective when installed by professionals using the right materials.

At J & D Independent Roofing Inc., we specialize in SBS torch-on systems, which are highly durable, flexible, and built to withstand Edmonton’s extreme weather conditions. With proper installation and maintenance, a flat roof can last just as long as a sloped one—and stay just as dry.

Why Believing This Myth is Costly:

Some property owners avoid flat roofs altogether or neglect maintenance, assuming leaks are inevitable. This can lead to severe water damage, mold growth, and expensive repairs that were entirely preventable.

Myth #2: You Only Need to Replace a Roof When It Leaks

The Truth:

Waiting for visible leaks before replacing a roof is like waiting for your engine to blow before getting an oil change. By the time water enters your building, the damage has already been done—often to insulation, framing, and drywall.

Regular inspections and preventative maintenance can catch issues like membrane cracks, flashing failure, or seam separation before they cause bigger problems.

Why Believing This Myth is Costly:

Delaying roof replacement or repairs until leaks show up can mean doubling or tripling repair costs. Instead, think of your roof as an investment that requires periodic checkups—especially with Edmonton’s harsh freeze-thaw cycles.

Myth #3: All Roofing Materials Are Basically the Same

The Truth:

From asphalt shingles to torch-on membranes to metal sheeting, roofing materials vary widely in quality, cost, longevity, and suitability for certain climates and buildings. What works for a warm, dry climate may fail quickly in Alberta’s icy winters and summer storms.

At J & D Independent Roofing Inc., we tailor material recommendations to suit Edmonton's intense seasonal changes, your building’s architecture, and your budget.

Why Believing This Myth is Costly:

Choosing the wrong material—or a low-quality product—can shorten the lifespan of your roof by a decade or more. Worse, it may void warranties or lead to insurance issues if damage occurs.

Myth #4: Roofing Work is Only for Summer

The Truth:

While warm, dry weather is ideal for certain types of roofing, roof repairs and even full replacements can be done year-round, especially with the right materials and techniques. We provide services through all seasons, including winter, because we know that roofing issues don’t wait for the perfect forecast.

Why Believing This Myth is Costly:

Postponing critical roof work during fall or winter can expose your property to avoidable damage. Ice dams, snow buildup, and winter storms can worsen existing vulnerabilities and cause extensive (and expensive) structural issues.

Myth #5: A New Roof Doesn’t Need Maintenance

The Truth:

Even a brand-new roof requires ongoing maintenance to maximize its lifespan. Edmonton’s fluctuating temperatures, ice buildup, UV exposure, and wind can gradually wear down roofing materials.

Our Preventative Maintenance Programs are designed to catch small issues early—extending the life of your roof and protecting your investment.

Why Believing This Myth is Costly:

Skipping maintenance can void warranties, accelerate wear and tear, and lead to premature replacement. A well-maintained roof can last 20+ years, while a neglected one might need replacing in half that time.

Myth #6: DIY Roof Repairs Save Money

The Truth:

DIY repairs might seem like a quick fix, but roofing is a skilled trade for a reason. Mistakes in patching, sealing, or flashing often result in hidden water intrusion, which can lead to rot, mold, and structural deterioration.

Plus, working at heights without the proper training and safety gear is extremely dangerous.

Why Believing This Myth is Costly:

What starts as a DIY “fix” often ends up requiring costlier repairs down the road—sometimes even full roof replacements. Save yourself the risk and expense by calling in a professional roofing team like J & D Independent Roofing Inc.

Myth #7: Roof Warranties Cover Everything

The Truth:

Many property owners assume a roof warranty means they’re fully protected, but warranties often have strict terms and limitations. Some only cover materials, not labor. Others require regular maintenance by certified contractors to remain valid.

At J & D Independent Roofing Inc., we explain the fine print clearly and help you meet warranty requirements with our inspection and maintenance services.

Why Believing This Myth is Costly:

Assuming you're covered could mean unexpected repair bills if you haven’t maintained the roof according to warranty terms.

Myth #8: Commercial and Residential Roofing Are the Same

The Truth:

Commercial and industrial roofing systems differ significantly from residential ones. Flat commercial roofs require specialized materials, installation techniques, and drainage considerations.

Our team is experienced across residential, commercial, and industrial projects, allowing us to recommend the best solutions for each property type.

Why Believing This Myth is Costly:

Hiring a roofer without commercial experience can result in installation errors, drainage failures, and code violations. Trust professionals who understand the specific needs of your building type.
