The Biggest Roofing Myths (And the Truth Behind Them)

When it comes to roofing, there’s no shortage of myths floating around. Whether it’s advice passed down from a neighbor or outdated information found online, these misconceptions can lead to costly mistakes for homeowners and missed opportunities for contractors.

Let’s bust some of the biggest roofing myths and uncover the truths behind them.

Myth #1: All Roofs Are Created Equal

One of the most common misconceptions is that all roofs are essentially the same, so the cheapest option is the best option.

• The Truth: Roofing systems vary widely in quality, durability, and performance. For example, a roof with proper underlayment, metal valleys, and upgraded ventilation will last significantly longer and perform better than a bare-minimum installation. Cheap roofs often cut corners, leading to problems like leaks, poor energy efficiency, and premature failure. Investing in quality materials and a reputable contractor pays off in the long run.

Myth #2: A New Roof Is Just About Shingles

Many homeowners think that replacing a roof is as simple as slapping on new shingles.

• The Truth: A roof is a system, not just a layer of shingles. It includes components like underlayment, flashing, ventilation, and insulation. Each part plays a critical role in protecting your home and ensuring the roof performs as intended. Skipping or skimping on these components can lead to issues like moisture buildup, poor energy efficiency, and even structural damage.

Myth #3: You Can Install a New Roof Over the Old One

Some people believe that leaving the old shingles in place and installing a new layer on top is a good way to save time and money.

• The Truth: While this practice, known as “roof overlay,” is technically allowed in some cases, it’s rarely a good idea. Adding a second layer of shingles can trap heat, hide underlying damage, and put extra weight on your roof structure. It’s always better to tear off the old roof and start fresh to ensure a solid foundation.

Myth #4: Roofs Don’t Need Regular Maintenance

Once a roof is installed, many homeowners assume they can forget about it until there’s a problem.

• The Truth: Regular maintenance is essential to extending the life of your roof and preventing costly repairs. Simple tasks like cleaning gutters, inspecting for damage, and removing debris can make a big difference. For commercial properties, managed repair programs can help building owners save money by addressing small issues before they become big problems ‌7‌.

Myth #5: Metal Roofs Are Noisy and Prone to Rust

Metal roofs often get a bad rap for being noisy during rainstorms and susceptible to rust.

• The Truth: Modern metal roofing systems are designed with noise-dampening features and protective coatings that prevent rust. In fact, metal roofs are among the most durable and energy-efficient options available. They can last 50 years or more with proper care, making them a smart investment for homeowners looking for longevity and sustainability ‌4‌.

Myth #6: Roofing Warranties Cover Everything

Many homeowners believe that a roofing warranty will cover any issue that arises.

• The Truth: Roofing warranties vary widely and often have limitations. For example, manufacturer warranties typically cover defects in materials but not issues caused by improper installation. That’s why it’s crucial to work with a certified contractor, like an Owens Corning Platinum Preferred Contractor, who can offer extended warranties and ensure the roof is installed to the highest standards.

Myth #7: DIY Roofing Is a Good Way to Save Money

With the rise of DIY culture, some homeowners think they can save money by tackling roofing projects themselves.

• The Truth: Roofing is one of the most dangerous and technically demanding home improvement projects. Without proper training, tools, and safety equipment, DIY roofing can lead to serious injuries and costly mistakes. Hiring a professional ensures the job is done safely and correctly, saving you money and headaches in the long run.

Myth #8: Roof Replacement Is Always the Best Option

When a roof shows signs of wear, many people assume it needs to be replaced entirely.

• The Truth: In some cases, repairs or partial replacements can address the issue without the need for a full roof replacement. A professional inspection can help determine the best course of action, saving you money while ensuring your roof remains in good condition.
