Do roofing companies offer warranties? Yes, but they vary greatly in coverage and value. The real difference comes down to whether you are looking at a manufacturer’s warranty or a workmanship warranty. This guide explains how each works, what can cancel your coverage, and how to get the most out of the protection you choose.
The Two Essential Types of Roofing Warranties
Most roofing projects offer warranty options, but many homeowners are not sure what each type covers. Knowing both helps you protect your roof and your budget.
Manufacturer's Material Warranty
Manufacturer warranties cover defects in the actual roofing materials: your shingles, underlayment, and other components. According to the National Roofing Contractors Association, material defects account for less than 5% of all roofing failures, yet this warranty remains crucial for your protection.
Typical coverage lasts 20 to 50 years for architectural shingles. Some companies advertise “lifetime” coverage, but that usually means for as long as you own your home or for a maximum of 50 years.
What manufacturer warranties cover:
- Premature granule loss on asphalt shingles
- Defects in manufacturing that cause shingle damage
- Failure of materials under normal weather conditions
- Faulty underlayment or ice barriers
What they don't cover:
- Problems caused by poor installation
- Weather damage beyond tested performance levels
- Ventilation issues in the roof system
- Normal wear from age
Workmanship Warranty from Contractors
While manufacturer warranties protect against material defects, workmanship warranties cover installation errors. The Insurance Institute for Business & Home Safety reports that improper installation causes up to 95% of all roofing problems, making this warranty arguably more valuable than material coverage.
Workmanship warranty lengths vary dramatically between contractors. Some offer minimal 2-year coverage, while established companies provide 10, 25, or even lifetime workmanship warranties. This variation reflects the contractor's confidence in their installation quality.
What Roofing Warranties Actually Cover (And What They Don't)
The warranty coverage landscape reveals significant gaps between homeowner expectations and actual protection. Let's examine what protection you really get.
Standard Coverage Inclusions
Most warranties address sudden product failures or installation issues, but the definition of “covered” varies by provider. Manufacturer warranties usually include the cost of replacing defective materials, but labor may only be included for the first few years. Strong workmanship warranties often include both labor and materials for fixing any installation-related problems.
Important coverage details:
- Leaks traced to faulty installation (workmanship warranty).
- Defective shingles that wear out too soon (manufacturer's warranty).
- Improper flashing installation that allows water in.
- Missing or incorrectly placed fasteners.
Common Exclusions That Surprise Homeowners
Careful reading of the fine print reveals that many warranties will not pay for certain issues. Lack of regular maintenance or making changes without approval can void your coverage entirely.
Typical warranty exclusions include:
- Severe weather events such as hurricanes, tornadoes, or earthquakes.
- Damage from falling trees or airborne debris.
- Issues caused by walking on the roof or installing equipment.
- Problems related to ice dams or interior condensation.
- Any alterations made without manufacturer's authorization.
Factors That Can Void Your Roof Warranty
Even a strong warranty becomes useless if it is voided. Knowing the most common causes of cancellation helps protect your investment.
Installation and Modification Issues
Having work performed by non-certified contractors or making changes without approval is the fastest way to lose coverage. Adding solar panels, satellite dishes, or HVAC equipment without following the manufacturer’s guidelines will often void a warranty immediately. Even small changes, such as adding attic fans or skylights, require the right approvals.
Mixing products from different manufacturers is another common mistake. For example, using one brand’s shingles with another’s underlayment may seem harmless, but it can void all coverage. Choosing the right materials from the start — and keeping them consistent — is essential.
Maintenance and Ventilation Problems
Poor attic ventilation causes more warranty denials than any other maintenance issue. Without proper airflow, heat buildup accelerates shingle deterioration and creates conditions manufacturers won't cover. The Department of Energy recommends 1 square foot of ventilation for every 300 square feet of attic space with vapor barriers.
Regular maintenance should include:
- Annual professional inspections
- Cleaning and maintaining gutters
- Removing roof debris
- Promptly repairing minor damage
- Ensuring proper attic ventilation year-round
How Long Do Different Roofing Warranties Last
Warranty length depends on the type of material, the quality of the installation, and the stability of the contractor who installed it. Knowing these timelines helps you set clear, realistic expectations for how long your roof will be protected.
Material Warranty Durations by Type
Different roofing materials come with varying warranty lengths. Premium materials like natural slate roofing often carry longer warranties than standard asphalt shingles, reflecting their superior durability.
Typical warranty periods:
- 3-tab asphalt shingles: 20–25 years
- Architectural shingles: 30–50 years
- Metal roofing: 30–50 years
- Slate and tile: 50+ years
- Cedar shakes: 20–30 years
Workmanship Warranty Variations
Contractor warranties reveal much about a company's confidence and stability. While some contractors offer minimal 1-2 year coverage, established companies with strong reputations often provide 10-25 year workmanship warranties. The Better Business Bureau reports that companies offering longer warranties typically have 40% fewer complaints than those with minimal coverage.
Your knowledge of how long different roofs last helps you evaluate whether warranty terms align with realistic performance expectations.
Extended and Enhanced Warranty Options
Many manufacturers give homeowners the option to upgrade their coverage through certified contractor programs. These enhanced warranties offer broader protection but require installation by contractors who meet strict training, insurance, and performance standards.
Manufacturer Certification Programs
Brands such as Owens Corning, GAF, and CertainTeed run certification programs for contractors. Meeting these standards allows contractors to offer premium warranty packages that may include:
- Longer labor coverage
- Non-prorated material replacement
- Coverage for tear-off and disposal costs
- Workmanship coverage backed by the manufacturer

System Warranties vs. Material-Only Coverage
System warranties are the most complete form of roofing protection. They cover the entire roofing system when all components are from the same manufacturer. This creates a single point of accountability if a problem comes up.
Advantages of a system warranty:
- One source for all coverage and claims
- Protection for every roof component
- Simplified claims process
- Often includes higher wind coverage
- May include coverage for related damages
How to File a Strong Warranty Claim
If your roof develops a problem, the claims process will decide how much of the repair is covered. A successful claim requires clear documentation and following the specific steps outlined in your warranty.
Documentation Requirements
Before starting a claim, gather complete documentation. Both manufacturers and insurers want proof that the roof was installed correctly, maintained properly, and that the issue is clearly identified. The Insurance Information Institute notes that claims with thorough documentation have a 73% higher approval rate.
Essential documentation includes:
- Original warranty certificates
- Installation invoices and signed contracts
- Maintenance and inspection records
- Photographs of any damage or defects
- A written description of the problem
- Records of past repairs
The Right Contractor Makes All the Difference
The claims process typically starts with contacting your installing contractor for workmanship issues or the manufacturer for material defects. Reputable contractors often handle manufacturer claims on your behalf, streamlining the process.
However, if your contractor has gone out of business, you'll need to work directly with manufacturers or find another certified contractor to assess and document issues.
How to Select a Contractor Who Offers Strong Warranty Protection
Your choice of roofing contractor directly impacts warranty quality and reliability. Established contractors with solid reputations offer superior warranty terms backed by financial stability.
Red Flags to Watch For
Be cautious of contractors offering unusually long warranties without a proven track record. A “50-year workmanship warranty” from a company that has only been around for two years is a warning sign. Also, avoid contractors who cannot show proof of manufacturer certification or active insurance coverage.

Questions to Ask Before Signing
Smart homeowners ask specific warranty questions before committing to any roofing project. Get clear, written answers about coverage terms, transferability, and claims procedures. Request examples of actual warranty documents and ask for references from customers who've successfully filed claims.
Critical warranty questions:
- What does the workmanship warranty cover compared to the material warranty?
- How long does each warranty last?
- Is the warranty transferable if I sell my home?
- What maintenance is required to keep the warranty valid?
- Who handles claims if your company closes?
