When investing in a commercial roofing project, it’s crucial to understand the various warranties available. These warranties protect your investment and ensure peace of mind. At United Contracting & Roofing LLC, we emphasize the importance of choosing the right warranty tailored to your needs.
What is an NDL Warranty?
An NDL (No Dollar Limit) warranty, often referred to as a Total System Warranty, is the top-tier warranty offered by many commercial roofing manufacturers. This warranty covers the entire roofing system without any dollar limit on the repair or replacement costs during the warranty period. Popular manufacturers like Carlisle, Versico, and GAF offer these warranties, ensuring comprehensive protection.
Benefits of an NDL Warranty
An NDL warranty offers extensive coverage, including all components of the roof system such as membrane flashings, drainage details, and insulation. This warranty is particularly favored in new commercial constructions due to its comprehensive nature. The primary benefit is the assurance that, should the roof fail within the warranty period, the manufacturer will cover the full cost of repairs or replacement without any financial limit.
Coverage Under an NDL Warranty
NDL warranties cover:
- Internal roof drains
- Through wall scuppers
- Gutter lines
- Membrane flashings around curbs, skylights, and parapet walls
- Roof insulation
This extensive coverage ensures that all critical components of the roof system are protected, minimizing the risk of unexpected expenses.
Exclusions in an NDL Warranty
However, NDL warranties do not cover:
- Acts of God (e.g., hurricanes, tornadoes, lightning)
- Maintenance issues due to neglect
- Roof modifications or alterations by unauthorized contractors
- Leaks caused by non-roofing materials (e.g., HVAC units, brick)
- Chemical exposure damage
Maintaining the warranty requires adherence to proper maintenance and involving authorized contractors for any roof-related work.
Manufacturer Material and Labor Warranties Explained
A step below NDL warranties, manufacturer material and labor warranties cover defects in both materials and workmanship but with certain limitations. These warranties are prorated, meaning coverage diminishes over time, and may exclude some components of the roofing system. This type of warranty can lower initial investment costs while still offering substantial protection.
Understanding Material-Only Warranties
Material-only warranties are often free and cover defects or premature aging of the roofing materials. Typically lasting between 10 to 20 years, these warranties do not cover labor costs or additional roofing components, focusing solely on the materials used.
Providers of Commercial Roof Warranties
Commercial roof warranties are generally provided by the material manufacturer or the installer. Authorized roofing contractors, trained and certified by manufacturers, must install the roof to qualify for NDL and material and labor warranties. This ensures that the installation meets the manufacturer’s specifications and standards.
Importance of Hiring an Authorized Roofing Contractor
Hiring an authorized roofing contractor is crucial for obtaining comprehensive warranties. These contractors are trained to install the roofing system according to the manufacturer’s specifications, ensuring the validity of the warranty. Inspections by manufacturer-appointed inspectors further guarantee that the installation is up to standard.
Conclusion: Choosing the Right Warranty for Your Commercial Roof
