Why Most Homeowners Misunderstand Their Roof Warranty

After a new roof goes on, most homeowners file the paperwork away and do not think about it again until there is a problem. By that point, some are surprised to find that the warranty they assumed covered everything has significant limitations they were not aware of.

Roofing warranties are not complicated, but they do require a basic understanding of how they are structured. Two warranties cover a new roof. They come from two different sources. They cover two different types of problems. And each has its own set of conditions that can limit or void coverage.

Understanding this before you need it is far more useful than finding out after a leak appears.

The Two Warranties Every New Roof Carries

Every quality roof installation involves two distinct warranties working alongside each other.

The first is the manufacturer warranty. This comes from the company that made the shingles and covers defects in the roofing materials themselves. If a shingle fails because of how it was manufactured, the manufacturer is responsible.

The second is the workmanship warranty. This comes from the roofing contractor and covers defects in how the roof was installed. If a roof leaks because a flashing was improperly set or a vent was not correctly seated, that is an installation problem, and the contractor’s workmanship warranty is what applies.

These two warranties do not overlap. They address different failure points. When a problem shows up on a roof, identifying whether it is a material failure or an installation failure determines which warranty is relevant.

What the Manufacturer Warranty Actually Covers

The manufacturer warranty covers defects in the roofing product itself. Common covered scenarios include shingles that delaminate, blister from a manufacturing defect, lose granules at an abnormal rate due to poor adhesive, or otherwise fail in ways that trace back to how the product was made.

What it does not cover is equally important.

• Storm damage of any kind, including hail, wind, and ice, is not a manufacturing defect and is not covered
• Improper installation that causes the materials to fail prematurely is typically excluded, as the manufacturer did not control the installation
• Damage caused by inadequate attic ventilation is a common and significant exclusion. If your attic overheats because of poor intake and exhaust ventilation, it accelerates shingle degradation from below. Most manufacturers require adequate ventilation as a condition of warranty coverage
• Installation over an existing layer of shingles can void coverage on some product lines
• Modifications to the roof after installation, including work done by someone other than a licensed contractor, can void coverage

Most manufacturer warranties on architectural shingles are marketed as lifetime limited warranties. That designation means coverage applies for as long as you own the home, but the fine print typically includes prorated coverage after a certain point. In the early years, a defect claim may result in full replacement value. Later in the roof’s life, the manufacturer’s contribution decreases on a sliding scale.

What the Workmanship Warranty Actually Covers

The workmanship warranty covers problems that trace back to how the roof was installed. If your roof leaks because flashing around a chimney was not properly integrated, because a pipe boot was not correctly sealed, because nails were improperly placed, or because any other installation step was done incorrectly, the workmanship warranty is what addresses it.

This warranty is entirely controlled by the contractor. Its value depends entirely on the contractor’s commitment to standing behind their work and their ability to do so over time. A workmanship warranty from a contractor who is out of business in three years is worth nothing.

Workmanship warranty terms vary significantly across the industry.

• Some contractors offer one year
• Others offer two to five years
• The strongest contractors offer lifetime workmanship warranties, which means they stand behind the installation for as long as you own the home

Above All Roofing provides a lifetime workmanship warranty on every roof we install. We do this because we believe the installation should hold up as long as the roof does, and because we intend to be in business and available to stand behind that commitment.

What Can Void Your Roof Warranty?

Several actions or conditions can reduce or eliminate warranty coverage entirely. Being aware of them helps you avoid inadvertently voiding protection you paid for.

• Inadequate attic ventilation. This is the most commonly overlooked void condition. Both manufacturer and workmanship warranties typically require that the attic be properly ventilated with adequate intake at the eaves and exhaust at or near the ridge. A reputable contractor addresses ventilation as part of any roof replacement.
• Unauthorized modifications. Having work done on the roof by a contractor other than the original installer, or by an unlicensed individual, can void the workmanship warranty. This includes adding solar panels, satellite dishes, or other penetrations without involving the original contractor.
• Improper maintenance. Pressure washing, walking on the roof without care, or using chemical treatments not approved by the manufacturer can damage the shingle surface and void coverage.
• Installing over existing layers. Most manufacturer warranties require installation on a clean deck. Installing a second layer of shingles over an existing layer can void the manufacturer warranty entirely.
• Failure to register. Some manufacturers require the homeowner or contractor to register the warranty within a specific window after installation. Missing that deadline can reduce coverage from the enhanced tier to the standard tier.

Enhanced Manufacturer Warranties Through Certified Contractors

Many major shingle manufacturers offer two tiers of warranty coverage. The standard warranty is available to any homeowner whose roof is installed with that manufacturer’s product. The enhanced warranty, which offers longer coverage periods and additional protections, is only available when the work is completed by a contractor who holds a certification from that manufacturer.

Certified contractors go through training and meet installation standards set by the manufacturer. In exchange, their customers gain access to warranty upgrades that are not available through uncertified installers.

Above All Roofing holds manufacturer certifications that make enhanced warranty tiers available to our customers. Ask us about the specific products and warranty levels applicable to your project.

What Happens When You File a Warranty Claim?

For a manufacturer warranty claim, the process typically starts with contacting the manufacturer directly. You will need documentation of the product installed, proof of purchase, and evidence of the defect. Many manufacturers require a contractor or inspector to document the issue before they will process a claim.

For a workmanship warranty claim, you contact the roofing contractor. A reputable contractor will schedule an inspection, identify the source of the problem, and correct it at no cost if the issue falls within the scope of the warranty.

Keep your roofing contract, warranty documentation, and any inspection records in a file you can locate easily. These documents are what you need when a claim situation arises.

Frequently Asked Questions

Does my roof warranty transfer if I sell my home?

Many manufacturer warranties are transferable, though the process typically involves notifying the manufacturer and may include a transfer fee. The workmanship warranty transferability depends on the contractor’s specific policy. Check both warranty documents for transfer provisions before listing your home.

What is the difference between a prorated and a non-prorated warranty?

A non-prorated warranty provides the same level of coverage regardless of the roof’s age. A prorated warranty reduces the manufacturer’s contribution over time, so a claim made in year 25 results in a smaller payout than a claim made in year five. Most standard manufacturer warranties become prorated after a certain number of years.

If my roof leaks, how do I know which warranty applies?

That determination is made by inspecting the source of the leak. If the leak traces to a material defect, the manufacturer warranty applies. If it traces to an installation error, the workmanship warranty applies. A licensed roofing contractor can identify the source and point you toward the correct claim.

Do manufacturer warranties cover labor costs?

Standard manufacturer warranties typically cover material replacement only. Enhanced warranties available through certified contractors often include labor cost coverage as well. This is one of the most meaningful differences between the two tiers.

What if the contractor who installed my roof is no longer in business?

If the workmanship warranty is gone because the contractor closed, you may still have recourse through the manufacturer warranty if the issue is material-related. For installation-related problems with no active workmanship warranty in place, the cost of repair typically falls on the homeowner. This is one of the strongest arguments for choosing a contractor with an established local presence and a long track record.

Final Thoughts

A roofing warranty is only as useful as your understanding of what it covers and your ability to enforce it. Two warranties protect your investment. One covers the materials. One covers the installation. Both have conditions. Knowing those conditions before something goes wrong puts you in a much stronger position if you ever need to make a claim. Above All Roofing installs every roof with manufacturer-certified products and backs every project with a lifetime workmanship warranty.
