Roof Warranty Guide: Understanding Coverage, Protection & Value

A roof warranty protects one of your home’s biggest investments, your roof. At Mammoth Roofing & Solar, we help homeowners understand what their warranty covers, how long it lasts, and what steps ensure continued protection. Not all roof warranties are the same, so knowing the details can save you money and stress over the life of your roof.

What Is a Roof Warranty?

A roof warranty is a written guarantee that your roofing materials and installation will perform as expected. It safeguards you against product defects or workmanship errors. Depending on your roofing system and contractor, you may have one or more types of warranty coverage.

Types of Roof Warranties

1. Manufacturer’s Roof Warranty

This covers defects in roofing materials such as shingles, underlayment, or panels. If materials fail due to manufacturing issues, the manufacturer replaces them.

2. Workmanship Roof Warranty

Provided by your roofing contractor, this warranty protects you from leaks or failures caused by improper installation.

3. Extended Roof Warranty

Some manufacturers offer extended or comprehensive warranties that include both material and labor costs, providing full roof system protection.

What a Roof Warranty Covers

Typical roof warranty coverage includes:

  • Material Defects  Replacement of defective roofing products.

  • Wind Resistance  Coverage for wind damage up to rated limits.

  • Algae or Staining  Some shingles include coverage against discoloration.

  • Workmanship Errors  Repairs due to installation mistakes.

Fact: The Asphalt Roofing Manufacturers Association reports that asphalt shingle warranties often last 20–50 years depending on the product and installation quality.

What a Roof Warranty Does Not Cover

Even the best warranties have exclusions. Common limits include:

  • Improper Installation by unlicensed contractors.

  • Neglected Maintenance such as skipped inspections.

  • Severe Weather or Natural Disasters.

  • Unauthorized Additions like skylights or solar panels without approval.

  • Normal Aging and gradual wear.

How to Keep Your Roof Warranty Valid

Follow these steps to protect your roof warranty and avoid claim denials:

  1. Hire Certified Roofing Contractors. Use licensed, manufacturer-approved professionals.

  2. Schedule Regular Roof Inspections. Annual checkups document roof condition.

  3. Repair Quickly. Address leaks and damage immediately.

  4. Follow Manufacturer Guidelines. Always comply with care and maintenance requirements.

Fact: Some manufacturers require homeowners to register their roof warranty after installation to activate coverage.

Should You Buy an Extended Roof Warranty?

Consider investing in extended coverage if:

  • You live in areas with hail or strong winds.

  • Your roof uses premium materials such as metal or tile.

  • You plan to stay in your home long term.

About The Author

Founder. Builder. No Plan B.

For ten years, Scott worked jobs that looked stable on the surface—finance, insurance, corporate roles—but always felt like they belonged to someone else’s vision. He wasn’t building anything of his own, and the day-to-day offered little more than repetition.

After a personal and financial low point—including a Chapter 7 bankruptcy—he found himself starting over with almost nothing. A friend gave him a shot in roofing sales. Two small jobs in, someone wrote his commission on a napkin at a diner table. The number was more than he’d made in weeks. That’s when he saw what this industry could offer—not just income, but real ownership over your success.

From there, everything changed.

Scott built this company to give others the same shot he got. He doesn’t look for perfect résumés—he looks for people with drive, character, and something to prove. His goal is simple: train in weeks what took him a decade to learn, and create a path to success that’s real, not theoretical.

Today, he leads one of the fastest-growing roofing and solar teams in Texas—but he’s still walking jobs, coaching reps, and checking in with homeowners. Because no matter how big the company gets, the mission stays the same: do the job right, take care of your people, and never forget where you started.
