Shingle Roofing Warranties: Understanding the Different Types and Coverage Offered by Manufacturers


When investing in a new shingle roof for your home, it’s important to consider not only the quality of the materials but also the warranties provided by the shingle manufacturers. Understanding the different types of shingle roofing warranties and what they cover can help you make an informed decision and ensure the long-term protection of your investment. In this article, we will explore the various types of warranties offered by shingle manufacturers and delve into the specific coverage they provide.

1. Standard Material Warranty:

Most shingle manufacturers offer a standard material warranty that guarantees their product against manufacturing defects. This type of shingle roofing warranty typically ranges from 20 to 50 years and covers issues such as premature cracking, curling, or disintegration of the shingles. It’s important to carefully read and understand the terms and conditions of the material warranty, including any exclusions or limitations.

2. System Warranty:

In addition to the standard material warranty, some manufacturers offer system warranties that cover both the shingles and other components of the roofing system. This includes underlayment, starter strips, ridge caps, and ventilation products. System warranties provide a comprehensive level of protection by ensuring that all the elements of the roofing system work together to provide optimal performance.

3. Workmanship Warranty:

While the material and system warranties protect against manufacturing defects, a workmanship warranty focuses on the installation of the shingles. This type of shingle roofing warranty is provided by the roofing contractor and covers any installation errors or issues that may arise due to improper workmanship. Workmanship warranties typically range from one to ten years, but the duration can vary depending on the contractor.

4. Prorated vs. Non-prorated Warranties:

Shingle roofing warranties can be either prorated or non-prorated. A prorated warranty means that the coverage decreases over time as the roof ages. This reduction in coverage is often based on the remaining lifespan of the shingles. On the other hand, a non-prorated warranty provides the same level of coverage throughout the entire warranty period. It’s important to carefully compare and evaluate the terms of prorated and non-prorated warranties before making a decision.

5. Transferability:

Consider whether the shingle roofing warranty is transferable if you plan to sell your home in the future. Some warranties are transferable to subsequent homeowners, which can be an attractive feature that adds value to your property. Keep in mind that there might be specific requirements or fees associated with transferring the warranty, so be sure to review the transfer process outlined by the manufacturer.

6. Exclusions and Limitations:

Shingle roofing warranties often have exclusions and limitations that outline specific situations or conditions where the warranty may be void. These can include improper installation, extreme weather events, roof modifications, lack of proper maintenance, or non-compliance with manufacturer guidelines. It’s crucial to understand these exclusions to ensure compliance and maintain the validity of your warranty.


When investing in a shingle roof, understanding the different types of shingle roofing warranties offered by manufacturers is vital. By carefully reviewing and comparing the warranties, including their coverage, duration, proration status, and transferability, you can make an informed decision. Remember to work with a reputable roofing contractor who adheres to the manufacturer’s guidelines to ensure that your warranty remains valid and your investment in a quality shingle roof is protected for years to come.
