Commercial Roof Warranties: Your Guide to Roofing Warranty Options | OC Roof Kings
A. Definition of Commercial Roof Warranties
A commercial roof warranty is a contract provided by either the roofing manufacturer or contractor that guarantees the roof’s performance over a certain period. This warranty covers defects in materials, workmanship, or both, depending on the type of warranty.
B. Importance of Understanding Warranty Options
Understanding roofing warranty options is critical for commercial property owners and managers to protect their investment. A well-chosen warranty can reduce long-term costs, ensure quality maintenance, and help avoid unnecessary expenses from roofing failures.
Types of Commercial Roof Warranties
A. Manufacturer’s Warranty
This warranty is provided by the roofing material manufacturer and typically covers defects in materials, such as roofing membrane failure. Manufacturer’s warranties are generally limited in scope and duration
B. Workmanship Warranty
Workmanship warranties are provided by the roofing contractor. They cover issues arising from improper installation, such as leaks caused by subpar work. These warranties can range from 1-10 years, depending on the contractor’s policy and the complexity of the roof.
C. Material-only Warranties
| Warranty Type | Coverage | Duration | Who Provides It | Common Exclusions |
| Manufacturer’s Warranty | Materials defects | 10-20 years | Manufacturer | Improper installation |
| Workmanship Warranty | Installation errors | 1-10 years | Roofing Contractor | Materials defects |
| Material-only Warranty | Material defects only | 5-20 years | Manufacturer | Installation or labor |
| System Warranty | Entire roofing system | 10-30 years | Manufacturer | Weather-related damage |
| NDL Warranty | Unlimited coverage (financial) | 20-50 years | Manufacturer | Neglect or abuse |
D. Labor and Materials Warranty
This warranty covers both the labor and materials used in the roofing system. It is often a more comprehensive option that guarantees proper installation and quality materials. This warranty is essential for ensuring that roofing failures are not the result of either material defects or installation mistakes.
E. System Warranties
A system warranty covers the entire roofing system, including all components, such as the membrane, insulation, and drainage. This type of warranty typically offers more extensive protection and is common with high-end commercial roofs.
F. NDL Warranties (No Dollar Limit)
NDL warranties are among the most comprehensive, offering unlimited financial protection against roof failure. These warranties are typically provided by well-established manufacturers and ensure that all repairs and replacements are covered.
Coverage of Commercial Roof Warranties
A. What Warranty Covers
Commercial roof warranties typically cover roofing defects, material failure, leaks, and certain types of weather damage. However, the extent of coverage can vary greatly depending on the warranty type and provider.
B. Warranty Coverage Details
The warranty should specify the exact types of failures covered, how to make claims, and the timeframe during which claims are accepted. It is essential to read these details carefully to understand what is covered
C. Common Exclusions (e.g., Defects Not Covered)
Many warranties exclude damage caused by external factors such as severe weather (e.g., hail, wind) and neglect (e.g., failure to maintain the roof). Some warranties also exclude damage caused by improper installation or modifications made to the roof after the warranty was issued
D. Warranty Claim Process
To file a warranty claim, the owner must typically provide proof of maintenance records and a detailed description of the issue. Many manufacturers and contractors will require an inspection to determine if the claim is valid under the warranty’s terms.
Factors Affecting Warranty Validity
A. Role of the Roofing Contractor
The roofing contractor plays a significant role in ensuring that warranties remain valid. A certified, experienced contractor will follow manufacturer instructions and use proper installation techniques to ensure the roof performs as expected.
B. Importance of Proper Installation
Proper installation is crucial for warranty validity. Many warranties stipulate that if a roof is not installed correctly, the warranty will be void. Ensuring that the roof is installed by a certified contractor can help maintain coverage.
C. Regular Roof Inspections
Regular inspections by professional roofers are essential to identify and fix any minor issues before they become major problems. This is often required for warranty maintenance and to prove that the roof has been properly maintained.
D. Severe Weather Considerations
Most warranties have clauses that limit coverage for weather-related damages such as storms, hail, or extreme temperatures. Commercial property owners should consider additional weather-related insurance for complete protection.
| Action that Voids Warranty | Manufacturer’s Warranty | Workmanship Warranty | Material-only Warranty | NDL Warranty |
| Unauthorized modifications | No | Yes | No | No |
| Severe weather damage | Yes | No | Yes | Yes |
| Lack of regular maintenance | Yes | Yes | Yes | Yes |
| Incorrect installation | No | Yes | Yes | No |
Actions That Could Void the Warranty
E. Actions That Could Void the Warranty
Certain actions such as using the roof for unauthorized purposes, installing incompatible materials, or failing to perform regular maintenance can void the warranty. Property owners must adhere to all warranty guidelines to ensure continued protection.
Choosing the Right Warranty
A. Evaluating the Warranty Options
When choosing a warranty, evaluate its coverage scope, terms, and exclusions. It is essential to balance cost with the level of protection to ensure long-term value.
B. Understanding Dollar Limits and Prorated Terms
Some warranties feature dollar limits (maximum payout) or are prorated, meaning the coverage decreases over time. These details are important to understand fully so there are no surprises when a claim is made.
C. Importance of Selecting a Reputable Roofing Manufacturer
A reputable roofing manufacturer will offer more reliable warranties with fewer exclusions. It is important to choose manufacturers known for high-quality materials and reliable customer service.
D. Recommendations for Commercial Property Owners
Commercial property owners should work with a licensed, experienced roofing contractor and select warranties that provide comprehensive coverage. They should also regularly review warranty terms to ensure they are in compliance and to identify opportunities for additional protection.
Maintaining Your Commercial Roof
A. Regular Maintenance and Inspections
Routine maintenance and annual inspections by a professional roofing service will extend the lifespan of your roof and ensure warranty coverage remains intact.

Proper roof upkeep can prevent costly repairs in the future and preserve the building’s energy efficiency. Regular cleaning, clearing debris, and repairing minor issues promptly can extend the roof’s life.

Addressing any defects promptly can prevent further damage to the roof, which may not only lead to warranty claims but also reduce long-term repair costs.
