Roof Warranties Explained: Manufacturer vs. Workmanship Coverage

When we hand a homeowner an estimate for a new roof, the warranty is usually the last line they read and the first thing they wish they had read closer. “Fifty-year warranty” sounds like the roof is covered for fifty years, no matter what. It isn't, and the gap between what people assume and what the paperwork actually says is where a lot of frustration lives — especially after the first big hailstorm rolls through the Hill Country.

A new roof really comes with two different promises from two different parties: one from the company that made the materials, and one from the company that installed them. They cover different failures, they're voided in different ways, and neither one covers hail. Here's how we explain it to homeowners from Spring Branch to San Antonio, so you know exactly what you're buying before you sign.

The short answer

The rest of this post breaks down each type of coverage, what quietly cancels it, and a table at the end that tells you whether to call your roofer or your insurance company.

Two warranties, two different jobs

The manufacturer warranty covers the materials themselves. If a batch of shingles was made wrong and starts cracking, blistering, or shedding granules years before it should, that's a product defect, and the manufacturer stands behind it. On the systems we install, that coverage runs up to 50 years, and 35 years on metal. Many manufacturer warranties are prorated, though, which means the share they pay shrinks as the roof ages. Read that schedule before you assume the full replacement cost is covered in year 30.

The workmanship warranty covers the installation. A flashing detail done wrong, a valley that wasn't sealed properly, nails driven at the wrong angle — those aren't the shingle's fault, and the manufacturer won't pay for them. That promise comes from the contractor, which is why it is only worth as much as the company behind it. A workmanship warranty from a crew that sold you a roof and subbed it out to the cheapest bidder is a piece of paper with nobody standing behind it.

That's a big part of why we run all of our own crews and our own equipment. When we put a new roof on your house, the people who installed it are the same company that backs the workmanship.

Manufacturer vs. workmanship at a glance

Each row is a question homeowners ask us about their coverage. The highlighted cell is the warranty that actually answers it.

Terms vary by manufacturer, product line, and contractor. Your own warranty documents are the final word on what is covered.

What quietly voids a roof warranty?

Most warranties aren't lost in a single dramatic event. They're lost in small decisions years after the install: a satellite dish bolted through the shingles, a cheap patch by whoever was available after a leak, a second layer of shingles laid over the first to save on tear-off. Manufacturers write their warranties around a complete roof system installed to their specifications, so anything that changes that system can give them a reason to deny a claim.

Poor attic ventilation is another one that catches Texas homeowners off guard. Trapped summer heat bakes shingles from underneath, and many manufacturers treat an under-ventilated attic as an installation problem, not a product defect. If you're curious how that works, our post on attic heat and ventilation goes deeper.

Warranty or insurance: who pays for hail?

This is the question we hear most, because we do a lot of hail work around here. The honest answer: hail is weather, and weather isn't a manufacturing defect or an installation mistake. Standard roof warranties don't cover it. Hail, wind, and fallen limbs are what your homeowner's insurance policy is for.

We work with insurance companies all the time, and the process goes smoother when the damage is documented properly from the start. Hail bruising isn't always visible from the driveway, either — our post on hidden hail damage explains what to look for, and this guide to storm damage claims walks through working with your adjuster.

Does a metal roof warranty work differently?

The same two-part structure applies: the panel and finish are covered by the manufacturer, and the install is covered by the contractor. On standing seam metal, we use primarily mackleroy metal, and the coverage we offer runs 35 years on metal. Because we run our own metal machines and form panels in house, the panels on your roof and the people installing them come from the same shop.

If you're still deciding between materials, our metal vs. shingle comparison covers the trade-offs, and the roofing page shows the shingle, metal, and tile systems we install.

Who do you call: your roofer or your insurer?

Find your situation in the left column. The chips tell you which kind of coverage usually applies, and why. Every policy and warranty has its own fine print, so treat this as a starting point, not a ruling.

The bottom line

A good roof warranty is really two promises: a manufacturer standing behind the materials, and an installer standing behind the work. Protect both by keeping your registration paperwork, keeping the roof system intact, and calling the original installer when something needs fixing. When storms do the damage, that's an insurance conversation, and it helps to have a roofer who works with insurance companies regularly. And if a leak shows up, resist the urge to patch it yourself; our post on the hidden costs of DIY roof repairs explains why.
