A Roof Warranty Is Only as Good as the Company That Stands Behind It
J.N.Davis’ Roof Warranty
A true 10-year Workmanship Warranty + Manufacture’s Warranty
Why J.N. Davis Roofing’s 95+ Years of Experience Make All the Difference
When homeowners invest in a new roof, one of the first things they ask about is the warranty. A strong warranty can be the deciding factor between one roofing contractor and another. But what many don’t realize is that a roof warranty is only as good as the company that issues it.
If the roofing company goes out of business—or simply disappears when problems arise—that “10-year warranty” becomes nothing more than a piece of paper. That’s why working with a well-established, reputable company like J.N. Davis Roofing, which has served Southern California for more than 95 years, is one of the smartest choices you can make for your home and your peace of mind.
The Harsh Truth About Roofing Warranties
Roofing warranties sound comforting, but they often have more fine print than homeowners realize. Many new or fly-by-night contractors offer “lifetime” or “20-year” warranties that may not even last five years—because the company itself won’t last that long.
Here’s the reality:
A warranty is only enforceable if the company is still in business.
If the contractor shuts down, retires, or rebrands, there’s no one left to honor that warranty.Manufacturer warranties depend on proper installation.
Even if the shingle manufacturer still exists, their warranty only applies if the materials were installed correctly by a certified professional.Workmanship warranties require a reliable contractor.
If leaks or flashing problems arise years later, you need a roofing company that will answer the phone and stand behind their work—not disappear.
In short, a warranty’s real value isn’t in the words—it’s in the trustworthiness and longevity of the company offering it.
Why Longevity Matters More Than Anything
It takes years—often decades—to earn a strong reputation in the roofing industry. That’s why longevity is such a powerful indicator of quality, consistency, and customer care.
J.N. Davis Roofing isn’t just another contractor that popped up during the latest building boom. The company has been serving homeowners and businesses across Covina, Altadena, Pasadena, and the greater San Gabriel Valley for nearly a century.
That means:
95+ years of continuous service—surviving recessions, storms, and changing building codes.
Three generations of craftsmanship passed down through the family.
A deep local reputation built on honesty, reliability, and word-of-mouth trust.
Few roofing companies in California can claim that kind of history.
And that history matters—because it’s the best assurance that your warranty will actually mean something ten, twenty, or even thirty years from now.
What Happens When Roofing Companies Disappear
It’s not uncommon for smaller or newer roofing contractors to go out of business within a few years. The reasons vary: economic downturns, lack of experience, poor workmanship, or even legal disputes.
Unfortunately, when that happens, homeowners are left stranded.
Imagine this:
You hire a company that offers a “10-year workmanship warranty.”
Five years later, your roof is damaged from Santa Ana winds or a tragic fire.
You call the company—only to find the number disconnected and the website gone.
Now you’re on your own, paying out of pocket for repairs that were supposed to be covered.
That’s the hidden cost of choosing an unproven roofing company. The short-term savings can turn into long-term headaches.

That’s why homeowners across Covina, Altadena, Pasadena, Glendora, Monrovia, and Claremont continue to trust J.N. Davis Roofing generation after generation.
Our longevity isn’t just a statistic—it’s a testament to how we do business:

That’s why our customers know that if something ever goes wrong, J.N. Davis Roofing will be there to make it right.
The Hidden Perils of “Too-Good-To-Be-True” Roofing Deals
If you’ve ever seen a roofing quote that seems drastically cheaper than others, proceed with caution. Many of these companies:
Subcontract to unlicensed or inexperienced crews.
Use cheaper materials that void manufacturer warranties.
Fail to carry proper insurance or permits.
Offer “10-year warranties” (or longer) that are meaningless once the company dissolves.
Don’t protect their employees with Worker’s Compensation Insurance exposing you to lawsuits
By contrast, J.N. Davis Roofing offers competitive pricing based on honest, transparent estimates—not shortcuts. We know that a quality roof is an investment that should protect your home for decades, not just the next few seasons.
When you hire an established roofing company with nearly a century of success, you’re not just paying for materials and labor—you’re paying for trust, stability, and guaranteed accountability.
Understanding Your Roofing Warranty
Let’s break down the two main types of warranties you’ll encounter:
1. Manufacturer (Material) Warranty
This covers defects in roofing materials—such as shingles, tiles, or metal panels. Most top-tier manufacturers only honor their warranties if the roof was installed by a certified contractor following their specific guidelines.
As a long-standing, certified installer, J.N. Davis Roofing ensures your manufacturer’s warranty remains fully valid.
2. Workmanship (Labor) Warranty
This is issued directly by the roofing company to cover installation errors or workmanship defects.
If you hire a contractor who’s only been in business a few years, that warranty might vanish if the company does.
But when you choose J.N. Davis Roofing, you’re backed by a company that’s been here for 95+ years—and plans to be here for the next 95.
