What Is a Manufacturer Warranty?

A manufacturer warranty comes from the company that makes the roofing materials, usually the shingles.

It covers defects in the materials themselves.

For homeowners, a manufacturing defect means something went wrong during the production process not during installation.

Examples of manufacturing defects may include:

  • Premature granule loss
  • Shingles cracking earlier than expected
  • Curling or blistering caused by production defects
  • Factory defects that lead to premature roof failure

 

For example, if shingles fail prematurely because of a manufacturing issue, the manufacturer may cover:

  • Replacement materials
  • In some cases, a portion of labor (depending on the warranty terms)

 

These warranties can range from 20 years to lifetime coverage, depending on the product.

What Is a Workmanship Warranty?

A workmanship warranty is provided by the roofing contractor.

It covers how the roof was installed.

If something goes wrong due to installation errors, this warranty typically covers:

  • Labor to fix the issue
  • Repairs related to improper installation
  • Corrections to mistakes made during the job

Common workmanship issues may include:

  • Improper flashing installation
  • Incorrect nail placement
  • Poor attic ventilation setup
  • Improper sealing around roof penetrations
  • Installation mistakes that lead to leaks

 

This is often the warranty that applies to the most common roofing problems homeowners experience.

Why Both Warranties Matter

A roof can fail for two main reasons:

  • The materials fail
  • The installation fails

If you only have one type of warranty, you may not be fully protected.

For example:

  • High-quality materials won’t perform well if installed incorrectly
  • Proper installation won’t fix defective materials

Having both warranties gives you more complete protection.

Which Warranty Matters More in Real-World Situations?

Both are important, but they don’t carry equal weight in most situations.

Most roofing problems are related to installation, not materials.

That means the workmanship warranty often plays a larger role in protecting your investment.

Installation-related issues happen more frequently because roofing systems are assembled on-site by people. Even high-quality materials can fail if flashing is installed incorrectly, nails are misplaced, or ventilation shortcuts are taken.

Common causes of workmanship-related issues include:

  • Rushed labor
  • Inexperienced crews
  • Improper flashing installation
  • Ventilation shortcuts
  • Failure to follow manufacturer installation requirements

 

Manufacturing defects can happen, but they are generally less common than installation-related problems.

However, the best approach isn’t choosing one warranty over the other it’s making sure you have both.

What Homeowners Should Watch Out For

Not all warranties offer the same level of protection.

Here are a few things to pay attention to:

Vague Warranty Language

If coverage isn’t clearly explained, it can lead to confusion later.

Extremely Short Workmanship Warranties

This may indicate limited confidence in the installation.

Overpromising Without Details

A “lifetime warranty” should still come with clear terms and conditions.

Transferability Restrictions

If you may sell your home in the future, ask whether the warranty can transfer to the next homeowner. Some warranties are transferable, while others have limitations or deadlines.

Misunderstanding Coverage

Many homeowners assume every roofing issue is covered. In reality, each warranty has exclusions and limitations.

Questions to Ask About Roofing Warranties Before Hiring a Contractor

To better understand what you’re getting, ask:

  • What does your workmanship warranty cover?
  • How long does it last?
  • What is covered under the manufacturer warranty?
  • Who handles warranty claims if something goes wrong?
  • Is the warranty transferable if I sell my home?
  • Are there any exclusions I should know about?

 

Warranty Tip: If a contractor cannot clearly explain what their workmanship warranty covers, ask for the warranty details in writing before signing a contract.

These answers can help you compare roofing companies more effectively.

How Should Warranties Factor Into Your Roofing Decision?

Manufacturer and workmanship warranties serve different purposes but both are essential.

One protects the materials.

The other protects the installation.

Understanding the difference helps you avoid confusion, compare roofing companies more effectively, and make a more confident roofing decision.

At South Point Roofing, we spend time helping homeowners understand what warranty protection actually means before making a roofing investment. A warranty is only valuable if you understand what it covers, who handles claims, and how it protects your home when problems occur.

If you’re continuing your research, the next step is understanding how workmanship warranties work in real-world situations and how to evaluate roofing companies beyond warranty promises alone.
