Common Roofing Myths—Busted by the Experts

When it comes to your roof, there’s no shortage of advice—and unfortunately, not all of it is accurate. At Gerken Roofing, we’ve heard just about every roofing myth out there. As trusted roofers serving Pittsburgh, PA and the surrounding areas, we’re here to separate fact from fiction and help you make informed decisions about protecting your home.

Let’s bust some of the most common roofing myths.

Myth #1: If My Roof Isn’t Leaking, It’s Fine

The Truth: Just because your roof isn’t leaking doesn’t mean it’s in good shape. Hidden damage—like missing shingles, lifted flashing, or worn underlayment—can lead to major issues down the line. Preventive maintenance and regular inspections are key to avoiding costly repairs.

Myth #2: New Shingles Can Be Installed Over Old Ones

The Truth: While it’s legally allowed in some cases, Gerken Roofing never recommends “roof-overs.” Installing new shingles over old ones hides damage, adds unnecessary weight, and shortens the lifespan of your roof. A full tear-off ensures proper installation and long-term performance.

Myth #3: A Roof Will Last 30 Years, No Matter What

The Truth: Shingle lifespan depends on many factors—weather, ventilation, installation quality, and materials used. In Pittsburgh’s climate, with heavy snow and fluctuating temperatures, shingles may wear out faster than expected. We always evaluate your roof’s condition, not just its age.

Myth #4: All Roofing Materials Are Basically the Same

The Truth: There’s a big difference between entry-level shingles and premium products like Atlas or Owens Corning. Gerken Roofing uses high-performance shingles that offer better protection, longer warranties, and added resistance to algae, wind, and hail.

Myth #5: I Can Handle Roof Repairs Myself

The Truth: DIY roof repairs may save money upfront, but mistakes can lead to leaks, mold, and structural issues. Roofing work is dangerous and requires professional tools, techniques, and safety protocols. Trusting licensed, insured professionals like Gerken Roofing ensures it’s done right.

Myth #6: Roofing Warranties Cover Everything

The Truth: Warranties vary widely and often only cover materials—not labor or installation errors. At Gerken Roofing, we not only use shingles with strong manufacturer warranties, but we also back our craftsmanship with our own guarantee for peace of mind.

Myth #7: Roof Replacements Are Only Needed After Major Storms

The Truth: Storms can definitely damage roofs, but many roof issues are caused by long-term wear and tear, poor ventilation, or improper installation. Even without a storm, your roof could be due for replacement.
