Debunking Common Roofing Myths: Fact vs Fiction

Executive Summary

• Outdated and inaccurate roofing information is prevalent, leading many homeowners to make poor maintenance decisions that can lead to unnecessary expenses and long-term damage.
• Many homeowners mistakenly believe that roofs only require attention when they are leaking, that newly installed roofs don’t need inspections, and that roofing over old shingles is a clever shortcut.
• Some homeowners also wrongly believe that do-it-yourself (DIY) repairs are just as effective as hiring a professional and that all roofing materials, from asphalt shingles to composite tiles, perform equally well.
• Debunking common roofing myths and consulting a trusted roofing professional can help homeowners make more informed, safe, and cost-effective decisions for their homes.

How Roofing Myths Affect Homeowners

It is easy for roofing misinformation to spread among homeowners due to falsehoods being passed down from previous generations, picked up in online forums, or simply assumed through first-hand experiences. As a result, many homeowners hold misguided beliefs about roofs that can cause more harm than good. 

For example, some people wrongly believe that a roof only needs attention if it’s leaking and that new roofs don’t need inspections. Acting on myths like these can lead to issues such as shortened roof lifespans and even hazardous living conditions that demand expensive repairs. 

The guide below includes debunked common roofing myths that can help you protect your home and your budget. Although the common misconceptions and corrective facts outlined below can help you tailor your expectations about roofing, consulting an experienced roofing company is the best way to receive dependable advice tailored to your specific situation.

Common Ways That Roofing Myths Spread

Although technology and socialization are often helpful ways to acquire new information, today’s digital landscape and various communication avenues can also facilitate the spread of falsehoods. Some of the most noteworthy ways roofing misinformation can spread are:

• Word of mouth – Sometimes, well-meaning advice from friends or neighbors can actually be outdated or incorrect, making it unreliable.
• Do-it-yourself (DIY) content online – The internet is rife with DIY blogs and videos that often lack professional oversight and can therefore promote unsafe or ineffective roofing suggestions.
• Social media “hacks” – Pictures and short-form videos on social media platforms often feature viral roofing tips that appear convincing on the surface but are not time-tested or dependable.
• Misleading contractor claims – Some unscrupulous roofers may promote shortcuts or products that fail to deliver on their promises.
• Assumptions from other home projects – Roofs require individualized attention and customized approaches, meaning applying general home repair logic to roofing can contribute to costly mistakes.

Be cautious when digesting roofing information from the sources above, and ensure that you verify your findings with an experienced, honest roofing company before implementing any tips.

Top 5 Roofing Myths That Have Been Debunked

The five roofing myths mentioned below have been circulating on the internet and popping up throughout Beaverton, Tigard, Tualatin, and other parts of northwest Oregon.

Myth #1: A Roof Only Needs Attention When It Leaks

✗ Fiction: Everything is fine if your roof is not leaking.

✓ Fact: A leak, which can manifest as water stains on the ceiling, is often one of the last signs of a much bigger problem. Some examples of harder-to-detect damage that roofs can suffer before water ever makes its way inside are:

• Missing or cracked shingles
• Damaged flashing
• Clogged gutters
• Soft spots or rotting in the decking
• Algae or moss buildup
• Poor attic ventilation

This means that waiting for a leak can allow a wide range of other issues to brew below the surface, such as structural damage, insulation issues, or mold. Don’t let your roof reach this point; instead, you should schedule regular roof inspections to help identify and address potential problems promptly. Doing so can save you money and prevent more severe damage to your home.

Myth #2: New Roofs Don’t Need Inspections

✗ Fiction: A brand-new roof is guaranteed to be problem-free for years.

✓ Fact: Statistically, new roofs are less likely to have problems, but they’re not exempt from all issues. Some examples of problems that new roofs are susceptible to include:

• Installation errors due to improper setup or defective materials
• Damage from severe weather and falling debris
• Foot traffic or animal damage

All of the problems above can create vulnerabilities in newly installed roofing systems, sometimes without easily discernible signs.

Even if your roof was just installed, it can still benefit from a well-care checkup to ensure everything was done correctly and remains in good condition. In some cases, neglecting inspections on new roofs can void your warranty, making annual or bi-annual checkups a great way to keep your investment protected.

Myth #3: Roofing Over Old Shingles Saves Time and Money

✗ Fiction: It’s cheaper, faster, and practical to install new shingles on top of old ones.

✓ Fact: By cutting out the removal process, roofing over existing shingles may seem like a shortcut, but it can lead to more significant issues. Some problems that can come from roofing over old shingles can include: 

• Moisture can get trapped between the old and the new layer
• Structural issues below the new layer may go undetected
• Rain flow patterns may be affected and lead to pooling
• Manufacturers may void warranties if their materials are used in this manner
• Your roof may become heavier than it should be, jeopardizing its structural integrity

A full tear-off is essential because it allows roofers to inspect the decking and identify hidden damage before installing the new roofing materials. While this comprehensive approach may incur higher upfront costs, it offers a cleaner, safer, and more durable roofing solution that provides long-term protection for your home.

Myth #4: All Roofing Materials Are the Same

✗ Fiction: Asphalt, metal, tile, and other roofing materials all work the same.

✓ Fact: Roofing materials vary significantly in terms of performance, cost, and longevity. Some examples of popular roofing materials in Happy Valley, Lake Oswego, and other parts of the greater Portland area are:

• Asphalt – Asphalt shingles are made of paper or fiberglass with at least one layer of asphalt on top. It is commonly used because it is easy to install and affordable; however, it typically only lasts between 15 and 30 years.
• Metal – Although metal roofing may require a higher initial cost, it can resist fire and wind damage and last around 40 to 70 years. Stone-coated metal roofing can offer an extra layer of protection and aesthetic appeal.
• Composite tiles – These tiles are made of multiple materials, like fiberglass, asphalt, wood, paper, and other minerals. Roof Life of Oregon offers a 50-year warranty on the Brava composite shingles we install, guaranteeing longevity.

It is essential to select the right roofing material tailored to your climate, budget, and home design, as the wrong choice can result in higher energy bills, increased maintenance needs, or a shorter lifespan. Contact an experienced professional roofing contractor to help determine which material is best suited for your home.

Myth #5: DIY Roof Repairs Are Just as Good as Hiring a Pro

✗ Fiction: Anyone with a ladder, a hammer, and the necessary materials can fix a roof.

✓ Fact: Roofing is one of the most dangerous home improvement tasks and requires specialized knowledge. Not only does DIY roofing work pose a threat to the homeowner’s health by putting them at risk of falling, but improper repairs can also lead to more significant problems, such as:

• Voiding warranties or compromising home insurance coverage
• Creating safety hazards for inhabitants due to poor workmanship
• Getting fined for failing to meet building codes or permit requirements
• Reducing the home’s resale value due to unverified or undocumented work
• Shortening the roof’s lifespan by using improper materials or techniques

In many cases, DIY fixes often provide only temporary solutions and can complicate and increase the cost of future professional repairs. Therefore, you should hire a licensed roofing contractor to ensure peace of mind, as they can guarantee that the work is done safely, efficiently, and in accordance with code. Qualified professionals possess the tools and expertise necessary to identify problems that homeowners might overlook, and they can offer long-term solutions with warranties that safeguard the real estate investment.

Make Decisions Based on Facts, Not Myths

Relying on outdated or incorrect roofing information can ultimately prove costly for homeowners. Ignoring minor warning signs or relying on shortcuts and DIY solutions can lead to poor decisions and long-term consequences, including structural damage, voided warranties, expensive emergency repairs, and even a reduced home value.

Some steps you can take to empower yourself with accurate knowledge:

• Scheduling regular roof inspections, even for new roofs
• Avoiding cutting corners with overlay installations
• Selecting materials carefully by following expert advice
• Hire qualified professionals for repairs and maintenance

Your roof covers your home, making it the most critical defense system. Staying informed and treating your roof with care can ensure a safer, more efficient, and longer-lasting home.
