When it comes to roofs, misinformation is everywhere. Homeowners often make decisions based on outdated advice or well-meaning recommendations that just aren’t true. Unfortunately, these roofing myths can lead to poor choices, wasted money, and even property damage.
In this post, we’ll debunk five of the most common roofing misconceptions we hear at Liberty Roof Co.—so you can protect your home, wallet, and peace of mind.
Myth #1: You Only Need a New Roof If It Leaks
The Truth:
A leaking roof is a red flag—but it’s not the only sign you may need a replacement. By the time water enters your home, structural damage may already have occurred beneath the surface.
Other warning signs include:
- Shingle curling or cracking
- Excessive granules in gutters
- Sagging rooflines
- Flashing damage around chimneys or vents
- Interior mold or moisture in the attic

Why This Myth Persists:
Because roof leaks are the most obvious symptom of trouble, many homeowners assume they’re the only one. But ignoring subtler signs often leads to bigger repair bills later.
Myth #2: Metal Roofs Are Too Noisy in the Rain
The Truth:
Metal roofs today are typically installed with solid decking and insulation, which makes them no noisier than asphalt shingles during rainstorms.
In fact:
- Most modern metal roofing systems dampen sound
- Attic insulation further reduces noise
- Homeowners often report no difference in sound levels

Why This Myth Persists:
Older metal roofs—especially on barns or sheds—were often installed without underlayment or insulation, making them loud. Today’s systems are engineered for comfort and performance.
Myth #3: A New Roof Will Last Forever
The Truth:
Even the highest-quality roofing materials have a finite lifespan. Weather, ventilation, and installation all affect durability.
Average lifespans:
- Architectural shingles: 25–30 years
- Metal roofs: 40–70 years
- Flat roofs: 20–30 years
- Slate or tile: 50–100 years (but with proper care)
You should still:
- Inspect your roof annually
- Schedule professional inspections after storms
- Clean gutters and check flashing regularly

Why This Myth Persists:
Some roofing companies oversell durability without explaining the need for maintenance. A great roof is built to last—but only with proper care.
Myth #4: Roofing Over an Existing Roof Is Just as Good
The Truth:
While some codes allow a second layer of shingles, this shortcut can cause major problems:
- Adds weight to your home’s structure
- Covers up existing issues like rot or mold
- Shortens the life of the new shingles
- Can void manufacturer warranties
Tear-off and replacement is always recommended for long-term performance and resale value.

Why This Myth Persists:
Roof-overs are cheaper up front—but they cost more in the long run due to reduced performance and increased risk.
Myth #5: All Roofing Contractors Are the Same
The Truth:
The quality of your roof depends just as much on the installer as it does on the material. Hiring a licensed, experienced contractor ensures:
- Proper ventilation and underlayment
- Correct fastening and flashing installation
- Warranty protection
- Compliance with local building codes
Ask questions like:
- Are you insured and licensed?
- Do you offer a workmanship warranty?
- Can I see examples of your recent work?

Why This Myth Persists:
To the untrained eye, roofing might seem straightforward. But small errors can lead to major failures.
Bonus Myth: Roofing Is a DIY-Friendly Project
The Truth:
Replacing or repairing a roof is dangerous, complex, and heavily regulated. DIY attempts can:
- Void warranties
- Fail inspections
- Lead to injury
- Cause future leaks or structural problems
Always trust a certified professional to do the job safely and correctly.
