What Do Roofing Warranties Really Cover?
Investing in a new asphalt shingle roof is a major expense, and many homeowners in Sedona, Prescott, Cottonwood, and Camp Verde want to know: What protection does my warranty provide?
While roofing warranties offer peace of mind, they often come with limitations, exclusions, and maintenance requirements that homeowners should understand before issues arise.
This guide breaks down the types of roofing warranties, what they cover, and how to avoid voiding your warranty.
Types of Roofing Warranties
Most roofing warranties fall into three main categories:
Warranty Type | What It Covers | Typical Length |
Manufacturer’s Warranty | Covers defects in roofing materials | 20-50 years |
Workmanship Warranty | Covers installation errors & labor defects | 2-10 years |
Extended Warranty | Covers both materials & installation with additional benefits | 25-50 years |
1. Manufacturer’s Warranty (Covers Defective Shingles)
What It Covers:
- Material defects in asphalt shingles (e.g., cracking, premature granule loss, splitting)
- Manufacturer-related product failures
- Limited coverage for premature aging (if due to a production defect)
What It Doesn’t Cover:
❌ Improper installation – If your roofing contractor makes mistakes, the manufacturer won’t cover it.
❌ Storm damage – Hail, wind, and monsoon-related shingle damage is not covered.
❌ Poor maintenance – If you don’t clean your gutters or perform inspections, your warranty could be voided.

2. Workmanship Warranty (Covers Installation Issues)
What It Covers:
- Installation errors that cause leaks, premature wear, or structural issues
- Labor-related problems such as improper flashing installation or misaligned shingles
What It Doesn’t Cover:
❌ Shingle defects – That falls under the manufacturer’s warranty.
❌ Storm damage – Homeowners insurance typically covers this, not the workmanship warranty.
❌ Wear and tear from age – If your roof naturally deteriorates, it won’t be covered under installation guarantees.

3. Extended Warranties (Best Long-Term Protection)
Many manufacturers offer extended warranties that combine material and installation coverage.
Key Benefits of Extended Warranties:
✅ Covers both materials and workmanship defects
✅ Provides protection for 25-50 years
✅ May include labor costs for repairs
Downsides of Extended Warranties:
❌ Usually costs extra (typically $500-$2,000)
❌ Requires professional installation by a certified contractor

Common Warranty Exclusions: What’s NOT Covered?
Even with the best roofing warranty, homeowners should be aware of common exclusions.
Not Covered | Why? |
Hail, Wind, or Storm Damage | Handled by homeowner’s insurance, not warranty |
Leaks from Poor Ventilation | If attic airflow is inadequate, warranty can be voided |
Damage from Roof Modifications | Adding satellite dishes or solar panels may void coverage |
Mold, Algae, or Moss Growth | Considered a maintenance issue, not a material defect |
Improper Repairs or DIY Work | Warranties require professional installation & maintenance |

How to Avoid Voiding Your Roofing Warranty
Many homeowners accidentally void their warranty by not following the manufacturer’s installation and maintenance guidelines.
1. Hire a Certified Roofing Contractor
- Many manufacturers require installation by a certified contractor for warranty validity.
- DIY installation or hiring an unlicensed roofer can void coverage.
2. Maintain Proper Ventilation & Insulation
- Poor attic ventilation can cause shingle damage, which won’t be covered under warranty.
- Ensure ridge vents, soffit vents, and attic fans are properly installed.
