When investing in a new roof, the warranty is one of the most important aspects to understand—yet it's often overlooked. A well-defined roofing warranty protects not just the materials installed but the craftsmanship involved in the installation. Without this clarity, homeowners can be left vulnerable to unexpected expenses if something goes wrong. Whether you’re repairing storm damage or replacing an aging roof, knowing what’s covered under a roofing contractor’s warranty can save time, money, and stress down the road.
Warranties are not one-size-fits-all. They vary significantly between contractors and manufacturers, covering scope, duration, exclusions, and claim process differences. Intelligent Design Corp, a trusted provider of roofing services in Maple Grove, emphasizes the importance of understanding these differences before signing a contract. In this article, we’ll explain everything you need to know about roofing warranties to help you make informed decisions.
Read on to learn how each type plays a role in protecting your roof investment.
Understanding the Difference Between Workmanship and Manufacturer Warranties
Roofing warranties generally fall into two categories: workmanship warranties and manufacturer warranties.
The roofing contractor issues a workmanship warranty that covers installation-related issues. This type of warranty guarantees that the roof was installed properly and according to local building codes. If problems arise due to improper installation—like leaks or structural failures—the contractor is responsible for repairs within the warranty term. These warranties are critical because most roofing failures stem from installation errors rather than material defects.
On the other hand, a manufacturer’s warranty is issued by the roofing material manufacturer and covers defects in the roofing products themselves.
For instance, a manufacturer's warranty will often cover material replacement if shingles deteriorate prematurely or fail under normal weather conditions. However, these warranties typically do not cover labor unless specified, which is why having both types of coverage is essential for comprehensive protection.
It’s also worth noting that warranty terms and coverage can vary significantly by product line. Premium asphalt shingles often come with longer or even lifetime warranties, while basic lines may offer limited-term coverage.
What Is the Typical Duration of Roofing Warranties?
The duration of roofing warranties varies depending on the type and the materials used. Manufacturer warranties typically range from 20 to 50 years, with some high-end products offering lifetime coverage. However, these longer durations often cover only defects in the material—not installation errors—and may be prorated after a certain number of years, meaning the value of the warranty decreases over time.
Workmanship warranties issued by the contractor tend to be shorter.
They usually range from 1 to 10 years, depending on the contractor’s confidence in their work and local industry standards. Some contractors, like Intelligent Design Corp, may offer extended workmanship warranties as part of premium service packages, which adds significant value to the overall project. These warranties are especially important because most roofing failures occur within the first few years of installation due to workmanship issues.
Extended warranties, sometimes offered by manufacturers through certified contractors, can combine workmanship and material coverage for longer periods—sometimes 20 years or more—provided that the installation meets strict certification standards.
Common Exclusions in Roofing Warranties That Homeowners Should Know
While roofing warranties provide crucial protection, they also have exclusions limiting what is covered.
One of the most common exclusions is damage resulting from improper maintenance. For example, if a homeowner fails to clean gutters or remove debris from the roof, any resulting damage may not be covered. Another typical exclusion is damage caused by weather events beyond standard exposure, such as hurricanes or unusually large hail.
Alterations or repairs made by unauthorized contractors can also void warranties.
The warranty may be invalidated if a different contractor installs a satellite dish or modifies the flashing incorrectly. Homeowners should always consult their original installer before making changes to the roofing system. Additionally, aesthetic concerns—such as color fading or granule loss—are often excluded unless they affect performance.
Material warranties may also be prorated, meaning the coverage amount decreases over time.
For instance, a 30-year shingle may only be covered at full replacement cost for the first 10 years, with a declining percentage thereafter.
How Roofing Warranty Claims Are Processed and Handled
The warranty claims process typically begins with documentation.
Homeowners must provide proof of installation, warranty registration, and photographs or evidence of the issue. For manufacturer warranties, claims are usually filed through the manufacturer’s online portal or by contacting their customer service department. The manufacturer may send a representative to inspect the damage and determine if it qualifies as a material defect.
For workmanship warranties, the process involves contacting the roofing contractor directly.
The contractor inspects the issue and determines whether it stems from an installation error. If so, they are typically obligated to perform the necessary repairs at no charge. Timeliness matters—homeowners should report issues as soon as they are noticed to avoid the risk of claim denial due to delay or further damage.
Processing times vary, but contractors and manufacturers generally aim to resolve claims within a few weeks. Keeping all documents, inspection reports, and correspondence helps streamline the process. Clear communication and proactive follow-ups are key to a successful warranty claim, especially for large or complex roofing systems.
Can Roofing Warranties Be Transferred to a New Property Owner?
Yes, many roofing warranties can be transferred to a new property owner, but the terms and conditions for transfer vary.
Manufacturer warranties often allow a one-time transfer within a limited time frame (e.g., 30 to 60 days after the home sale). The new owner may be required to notify the manufacturer and pay a transfer fee. After transfer, the warranty may continue in full or convert to limited coverage, depending on the policy details.
Workmanship warranties are more contractor-dependent. Some contractors offer fully transferable warranties, while others do not. If a home is being sold, the seller should clarify transferability with their contractor beforehand. This can add value during real estate transactions and reassure buyers about the quality and durability of the roofing system.
Buyers should request warranty documentation when purchasing and verify that the warranty is eligible for transfer. Properly transferring warranties can preserve ongoing protection and ensure continued coverage through the remainder of the original warranty period.
