What Kind of Warranty Comes With a New Roof? Materials vs. Workmanship Explained

What Kind of Warranty Comes With a New Roof?

A new roof may have more than one type of warranty or guarantee. The two important categories homeowners should understand are coverage related to the roofing materials and coverage related to the contractor's workmanship.

That difference matters.

When we talk with homeowners at Roof Wiz, we encourage them not to stop at one question:

“Does my new roof have a warranty?”

Ask a better question:

“What exactly is covered, for how long, and who provides the coverage?”

Here is what you need to know.

What Is a Roofing Material Warranty?

A material warranty is coverage associated with the roofing products used on your home and is generally provided by the manufacturer according to its warranty terms.

For an asphalt shingle roof, that can involve the shingles and qualifying components included in the roofing system.

The important point is this:

• The roofing manufacturer makes the product. The roofing contractor installs it.
• Those are two different responsibilities.
• That is why homeowners should understand both sides of their roof protection.

What Is a Workmanship Guarantee?

A workmanship guarantee covers the contractor's installation work according to the contractor's stated terms.

Think about it this way.

You can purchase quality shingles, but those shingles still have to be installed correctly.

Details such as flashing, underlayment, ventilation, penetrations, and water management all matter to the finished roofing system.

Roof Wiz's company information specifies a 10-year workmanship guarantee on roofing services.



For homeowners comparing roofing contractors, workmanship coverage is something worth asking about before making a decision.

What's the Difference Between a Material Warranty and Workmanship Coverage?

The simplest answer is:

Material coverage = the roofing products.
Workmanship coverage = the installation.

They work together, but they are not the same thing.

This is why a long material warranty by itself does not tell you everything you need to know about the protection behind your new roof.

You should understand who is responsible if there is a product-related problem and who is responsible if there is an installation-related problem.

Does Roof Wiz Offer a Workmanship Guarantee?

Yes. Roof Wiz's documented company information states that we provide a 10-year workmanship guarantee on roofing services.

That reflects something we believe strongly as roofing professionals:

Installation matters.

Roof Wiz is a family-owned company serving Southwest Michigan and Northern Indiana, and our positioning emphasizes quality craftsmanship, straightforward service, and long-term homeowner peace of mind.

We don't want homeowners to simply hear the word “warranty.”

We want them to understand what stands behind their roof.

Do Roofing Manufacturers Offer Extended Warranties?

Depending on the roofing system, manufacturer, contractor qualifications, and warranty selected, extended manufacturer warranty options may be available.

Roof Wiz's roofing FAQ notes that manufacturer certification can provide access to extended manufacturer warranties.

The exact terms matter.

Do not assume every shingle, every roofing system, or every contractor automatically qualifies for the same coverage.

Ask your roofing contractor to explain the specific warranty options associated with the materials being quoted for your home.

What Can Affect a Roof Warranty?

Warranty requirements vary, so homeowners should read the actual terms associated with their roofing system.

Instead of focusing only on the number of years printed on a brochure, ask questions such as:

Who provides the warranty?
Is it the manufacturer, contractor, or both?

What parts of the roof are covered?
Understand which products and installation work are included.

How long does each type of coverage last?
Material and workmanship coverage may have different terms.

Is registration required?
Ask whether any paperwork needs to be completed after installation.

Are there maintenance requirements or exclusions?
Read the warranty documents instead of relying only on a verbal explanation.

What happens if I have a problem?
Know who you are supposed to call.

A reputable roofing contractor should be willing to walk you through these questions.

Why Does Workmanship Matter So Much in Michigan?

A roofing system in Southwest Michigan needs to deal with challenging weather.

Roof Wiz's roofing guidance identifies lake-effect snow, shoreline winds, and freeze-thaw cycles as important local considerations. It also emphasizes ice and water protection and balanced attic ventilation as parts of a properly installed roofing system.

That means the quality of the shingles is only part of the equation.

The installation underneath and around those shingles matters too.

Flashing has to manage water correctly. Ventilation has to be considered. Vulnerable areas need proper protection.

A premium roofing product cannot make poor workmanship irrelevant.

Should I Choose a Roofer Based on the Longest Warranty?

Not necessarily.

A warranty is important, but it should be considered alongside the contractor's workmanship, reputation, communication, licensing, insurance, installation process, and willingness to stand behind the job.

Roof Wiz's company profile identifies its 10-year workmanship guarantee, licensing and insurance, manufacturer credentials, and reputation for straightforward service among its competitive strengths.

There is also something a warranty document cannot completely show you: how the contractor treats customers when the job gets difficult.

Roof Wiz customer reviews repeatedly mention professionalism, work quality, responsiveness, cleanup, and confidence in the team after installation.

That matters when you are trusting someone with the roof protecting your home.

What Warranty Questions Should I Ask Before Signing a Roofing Contract?

Before choosing a roofer, ask:

1. What manufacturer warranty comes with these materials?
2. What workmanship guarantee do you provide?
3. How long does each type of coverage last?
4. What exactly is covered and excluded?
5. Does the warranty need to be registered?
6. Are upgraded or extended manufacturer warranty options available?
7. Who do I contact if I have a problem after installation?

Get the answers in writing and keep your warranty documents with your home records.

Quick Answer: What Does a New Roof Warranty Cover?

A new roof can have separate protection for roofing materials and installation workmanship. Manufacturer coverage relates to qualifying roofing products under the manufacturer's terms, while workmanship coverage relates to the contractor's installation under the contractor's terms. Roof Wiz provides a documented 10-year workmanship guarantee on roofing services.
