When investing in a new roof, homeowners often ask: “What kind of warranty comes with this?” It’s an important question, and the answer can be confusing. Not all warranties are created equal, and knowing the difference between a manufacturer’s warranty and a workmanship warranty can save you headaches, and money, down the road.
At Mason Company Roofing, we believe in being transparent so our customers know exactly what’s covered and what isn’t. Here’s what you need to know.
Manufacturer’s Warranty: Covers the Materials
A manufacturer’s warranty is provided by the shingle or product manufacturer, not the roofing company.
What it covers:
Defects in the shingles or roofing materials
Premature failure due to product issues
In some cases, extended coverage if installed by a certified contractor (like our GAF Master Elite status)
What it doesn’t cover:
Installation errors
Poor ventilation or structural issues with the home
Damage caused by storms, falling trees, or outside forces
Think of it this way: the manufacturer stands behind their materials, but not the way those materials are put on your roof.
Workmanship Warranty: Covers the Installation
This warranty comes directly from the roofing contractor. At Mason Company Roofing, we recently extended our workmanship warranty to 10 years because we stand behind the quality of our crews and our work.
What it covers:
Errors made during installation
Improper fastening, sealing, or flashing
Issues that stem directly from workmanship mistakes
What it doesn’t cover:
Material defects (that’s the manufacturer’s responsibility)
Storm or weather damage
Homeowner neglect, like not maintaining gutters or trimming overhanging trees
Why Both are Good
The strongest protection comes from having both warranties in place. That way, no matter whether the issue is with the materials or the installation, you’re covered.
Because Mason Company Roofing is a GAF Master Elite contractor (a certification earned by less than 2% of roofers nationwide), our customers get access to enhanced manufacturer warranties that many other contractors can’t offer. Combined with our 10-year workmanship warranty, you get peace of mind knowing your investment is protected from both angles.
Questions to Ask Your Roofer
When reviewing warranty options, always ask:
How long is your workmanship warranty?
Are you certified with the shingle manufacturer?
Does the warranty transfer if I sell my home?
What exactly does the warranty exclude?
Bottom Line
A roof is one of the biggest investments you’ll make in your home. Understanding the difference between a manufacturer’s warranty and a workmanship warranty ensures you know exactly how your home is protected.
At Mason Company Roofing, we make it simple: quality materials backed by top-tier manufacturer warranties, and skilled installation backed by our 10-year workmanship guarantee.
Peace of mind comes from knowing your roof is protected on all fronts, both the shingles above and the craftsmanship below.
