Understanding Roof Warranties: What Homeowners Should Know Before Signing

A new roof is a major investment—and one you expect to last for decades. But what happens if something goes wrong? That’s where a roof warranty comes in. However, not all warranties offer the same protection, and many homeowners are surprised to learn what is (and isn’t) covered. In this blog, we’ll break down the types of roof warranties, what to look for, and how to ensure you’re fully protected before signing the dotted line.

1. The Two Main Types of Roof Warranties

A. Manufacturer Warranty (Material Warranty)

This warranty comes from the manufacturer of the roofing materials—typically shingles, underlayment, or other components.

Covers:

• Defects in the roofing materials
• Premature deterioration or failure due to manufacturing errors

Does NOT Cover:

• Installation errors
• Damage from storms, foot traffic, or poor ventilation
• Labor to remove and reinstall materials (unless upgraded)

Typical Duration:
20–50 years, depending on the product and brand.

B. Workmanship Warranty (Labor Warranty)

This is provided by your roofing contractor and covers installation quality.

Covers:

• Mistakes made during installation
• Problems caused by poor workmanship (such as leaks or flashing issues)

Does NOT Cover:

• Material defects
• Damage from weather, fire, or external forces

Typical Duration:
1–10 years, though reputable contractors may offer longer or even lifetime coverage.

2. Why Both Warranties Matter

To fully protect your roof, you need coverage for both materials and labor. If your shingles fail due to a defect but weren’t installed properly, a manufacturer may void the warranty. Likewise, if the contractor makes an error but only offers a short warranty, you may be on the hook for costly repairs.

Always ask:
✔️ What does each warranty cover?
✔️ Who is responsible for handling claims?
✔️ Are there any conditions that void coverage?

3. Key Warranty Terms to Understand

• Prorated vs. Non-Prorated:
  A non-prorated warranty offers full coverage for a set period, while a prorated warranty decreases in value over time.
• Transferability:
  If you sell your home, can the warranty transfer to the next owner? Transferable warranties can boost home value.
• Exclusions and Limitations:
  Read the fine print. Common exclusions include poor ventilation, DIY repairs, neglect, or improper maintenance.
• Extended or Upgraded Warranties:
  Some manufacturers offer extended warranties when the roof is installed by a certified contractor using a full system of their products.

4. Common Roofing Warranty Pitfalls

1. Assuming All Warranties Are the Same
   Don’t rely on general terms like “lifetime.” Always ask for specifics.
2. Failing to Register the Warranty
   Some warranties require you to register them within a certain period after installation.
3. Skipping Maintenance Requirements
   Most warranties require regular maintenance and inspections to remain valid.
4. Hiring Unlicensed Contractors
   Improper installation often voids manufacturer warranties. Choose a certified roofer like TM Roofing & Construction Group.

5. Questions to Ask Your Roofing Contractor

• What type of warranty do you offer on workmanship?
• What brand(s) of materials are being used, and what do their warranties cover?
• Is the warranty transferable if I sell my home?
• What conditions would void the warranty?
• Do you offer or recommend upgraded warranties?

A reputable contractor will clearly explain everything and provide written documentation.
