Here's What They Aren't Explaining.
“Don’t worry. It comes with a lifetime roofing warranty.” You’ve probably heard that before.
It’s one of the most common selling points in the roofing industry. But here’s what many homeowners don’t realize:
That “lifetime warranty” often isn’t the roofing company’s warranty at all.
In many cases, they’re simply referring to the manufacturer’s product warranty—a warranty that comes with the shingles whether that company installs your roof or someone else does.
That doesn’t make it a bad warranty. It just means it may not protect you in the ways you think it does.
Before choosing a roofing contractor, it’s important to understand exactly who is providing your warranty, what it covers, and who you’ll call if something goes wrong.
Not All Roofing Warranties Are the Same
One of the biggest misconceptions homeowners have is believing there’s only one warranty.
In reality, there are usually two completely different warranties involved with a roof replacement.
1. The Manufacturer’s Warranty
This warranty comes from the company that made the roofing materials.
Manufacturers like GAF, Owens Corning, CertainTeed, and TAMKO all provide warranties against manufacturing defects. If a shingle itself is defective because of how it was produced, this is generally the warranty that applies.
The important thing to understand is this:
The roofing contractor didn’t create this warranty.They’re simply installing products that already include it.
Almost every certified contractor installing the same roofing system can offer some version of the manufacturer’s warranty. So when a roofing company heavily advertises a “lifetime warranty,” ask yourself:
Is that actually their warranty—or the manufacturer’s?
2. The Workmanship Warranty
This is where roofing companies truly separate themselves. A workmanship warranty covers problems caused by installation.
For example:
- Flashing installed incorrectly
- Improper nail placement
- Poor ventilation installation
- Incorrect shingle alignment
- Installation mistakes
- Water intrusion caused by workmanship
These aren’t material defects. They’re installation issues. And the manufacturer typically won’t pay for installation mistakes.
That’s why the workmanship warranty is often the most valuable warranty you’ll receive.
A Great Product Can Still Leak
Imagine buying the highest-quality shingles available. They’re manufactured perfectly.
But during installation:
- Flashing is reused.
- Nails are placed incorrectly.
- Ice and water shield isn’t installed where it should be.
- Ventilation isn’t adequate.
The shingles themselves didn’t fail. The installation did.
In that situation, the manufacturer’s warranty usually isn’t the solution because the roofing materials weren’t defective. The issue is workmanship.
That’s why the contractor you choose matters just as much as the roofing products they install.
The Best Warranty Is Worthless If the Company Disappears
Here’s another question many homeowners never think to ask.
Who will still be here in ten years?
A workmanship warranty only has value if the company honoring it is still operating.
That’s one reason working with an established local roofing company matters.
If you need warranty service years after installation, you want a contractor that’s still serving your community—not one that has moved on or closed its doors.
When evaluating roofing companies, ask:
- How long have you been in business?
- Do you have a permanent office?
- Who handles warranty claims?
- How long have your installers been with the company?
The answers often tell you more than the warranty paperwork itself.
Manufacturer Certifications Can Expand Your Protection
Leading manufacturers offer enhanced warranty programs through select certified contractors.
Companies that meet strict installation and training requirements may be able to offer warranty options that go beyond standard product coverage.
These enhanced warranties often provide additional protection because they’re available only through contractors who have demonstrated consistent installation quality.
Ask your roofing contractor:
- Are you manufacturer certified?
- Which enhanced warranties are available?
- What requirements must be met to qualify?
Those certifications show that the manufacturer has confidence in the contractor’s installation practices.
Read What the Roofing Warranty Doesn’t Cover
Many homeowners only read the warranty headline.
Few read the details.
Before signing a contract, ask questions like:
- Does the warranty cover labor?
- Does it cover tear-off?
- Are flashing components included?
- Is there a transfer option if I sell my home?
- What maintenance is required?
- Are there situations that void coverage?
Understanding these details before installation helps eliminate surprises later.
Why We Believe Warranty Conversations Should Be Transparent
At Van Martin Roofing, we believe homeowners deserve to understand exactly what they’re receiving.
That’s why we explain:
- Which protections come from the manufacturer
- Which protections come from us
- What each warranty covers
- How warranty claims are handled
- What homeowners can expect years after installation
We don’t believe warranty language should be confusing. It should give homeowners confidence.
The Vanguard Warranty
Because installation quality is just as important as roofing materials, Van Martin Roofing offers the Vanguard Warranty for qualifying roofing systems.
The Vanguard Warranty was created to provide homeowners with enhanced protection backed by our commitment to proper installation and long-term customer service.
More importantly, it’s backed by a company that has served Southwest Ohio for decades and plans to continue serving homeowners for decades to come. When you invest in a roof, you’re investing in a relationship—not just a product.
Don’t Compare A Roofing Warranty by Length Alone
It’s easy to compare numbers. Twenty-five years. Fifty years. Lifetime.
But those numbers don’t tell the whole story.
Instead, ask:
- Who is actually providing this warranty?
- Does it cover materials, workmanship, or both?
- Who do I call if there’s a problem?
- Will this company still be here years from now?
- Is the contractor certified by the manufacturer?
- What isn’t covered?
Those answers are often more important than the length of the warranty itself.
Look Beyond the Fine Print
A roofing warranty should give you confidence—not confusion.
The best roofing companies don’t rely on manufacturer warranties to sell their work. They stand behind their craftsmanship with clear workmanship warranties, explain the differences between warranty types, and remain available long after the project is complete.
At Van Martin Roofing, we believe homeowners deserve complete transparency. That’s why we take the time to explain every warranty option, answer your questions, and make sure you understand exactly what’s protecting your investment.
Whether you choose asphalt shingles or a premium metal roofing system, our goal is to provide lasting protection backed by quality installation, local service, and our Vanguard Warranty.
If you’re comparing roofing companies in Dayton, Columbus, Cincinnati, or anywhere in Southwest Ohio, schedule a free roof inspection with Van Martin Roofing. We’ll help you understand not just the roof you’re buying—but the protection that comes with it.
