When you invest in a new roof, you expect it to last for decades. But what happens if something goes wrong? That’s where a roof warranty comes in. Unfortunately, many homeowners don’t realize what’s truly covered—or not covered—until it’s too late.
This guide breaks down everything you need to know about roof warranty coverage, from common types and terms to questions you should ask before signing a contract.
Why Roof Warranties Matter
A roof warranty protects your investment by covering specific problems that might arise due to material defects or installation errors. A strong warranty:
- Offers peace of mind
- Shields you from unexpected repair costs
- Reflects the contractor’s or manufacturer’s confidence in their work
But not all warranties are alike, and knowing the difference can help you make smarter choices when comparing roofing companies.
The Two Main Types of Roof Warranties
1. Manufacturer (Material) Warranty
Issued by the shingle or material manufacturer, this warranty covers defects in the roofing products themselves.
What it typically covers:
- Shingle cracking, blistering, or curling due to manufacturing defects
- Premature granule loss
- Material degradation under normal weather conditions
What it doesn’t cover:
- Installation errors
- Improper roof ventilation or flashing
- Damage from weather events, pests, or foot traffic
Length:
Standard manufacturer warranties last 20–30 years, with some architectural shingles offering limited lifetime warranties.
Pro Tip:
Look for “non-prorated” periods, which offer full coverage early on before tapering off over time.
2. Workmanship Warranty
Issued by your roofing contractor, this warranty covers issues caused by installation errors or poor workmanship.
What it typically covers:
- Flashing installation problems
- Fastener or nail placement mistakes
- Underlayment misalignment
- Improper shingle sealing or layering
What it doesn’t cover:
- Manufacturer defects
- Damage from storms or foot traffic
- Issues caused by homeowner neglect (like clogged gutters)
Length:
Workmanship warranties range from 1 year to 25+ years, depending on the contractor and whether they’re certified by the manufacturer.

Enhanced Warranty Options
Some manufacturers offer extended or enhanced warranties when your roof is installed by a certified contractor using approved systems.
For example:
- GAF’s Golden Pledge® Warranty covers 50 years for materials and 25 years for workmanship.
- Owens Corning Platinum Warranty offers extended labor and material coverage.
These warranties often include:
- Non-prorated periods for materials
- Full coverage of tear-off and disposal
- Transferability to a new homeowner (at least once)
Ask Liberty Roof Co. about enhanced manufacturer warranties available for your chosen system.
Common Roof Warranty Terms Explained
Prorated vs. Non-Prorated:
A prorated warranty decreases in value over time, while a non-prorated warranty covers 100% of costs for a specified period.
Transferability
Can the warranty be transferred if you sell your home? Most warranties allow one transfer—great for resale value.
Tear-Off and Disposal:
Does the warranty cover the cost to remove and dispose of defective roofing material?
System Warranty:
Applies when all components (shingles, underlayment, flashing, etc.) come from the same manufacturer and are installed to spec.
What Can Void a Roof Warranty?
Many warranties include fine print that, if violated, voids coverage. Common causes of voided warranties include:
- Improper installation by a non-certified contractor
- Poor attic ventilation causing excess heat or moisture
- Installing new shingles over old ones (without tear-off)
- Use of unapproved materials or accessories
- Failure to perform required maintenance
Tip : Ask your contractor for care instructions—and follow them.
How to Protect Your Roof Warranty
For peak seasons (spring and fall), schedule your roof replacement at least 6–8 weeks in advance. This gives you time to:
-
Hire a certified, insured roofing contractor
Workmanship coverage is only as strong as the company behind it. -
Register your warranty
Many manufacturer warranties require online or mailed-in registration. -
Maintain your roof
Clean gutters, trim trees, and schedule inspections to catch problems early. -
Keep records
Save your installation contract, warranty documents, and any repair invoices. -
Schedule inspections after major storms
Document any damage and notify your contractor or insurer promptly.
