What Are Color Codes and Why Are They Used?
Color codes are essential identifiers used by manufacturers to keep track of production runs and specific color information for shingles. These codes help maintain consistency in the appearance of shingles across different production batches.
- Consistency Across Plants: Color names remain consistent from plant to plant. Each plant has an internally controlled list of unique codes that define the color of specific shingles.
- Same Color Code: As long as all bundles for a job have the same color code printed on the ends, the shingles should have a consistent appearance.
- Mixable Shingles: Shingles are mixable only if they have the same color code. If all bundles for a job have the same color code, the shingles will look uniform when installed.
Avoid Mixing Different Color Codes
It is crucial not to mix shingles with different color codes, as this can lead to visual inconsistencies. Occasionally, a bundle will have “Do Not Mix” printed on it, indicating a change in the product color. This is a clear signal to avoid mixing these shingles with others.
Where Are Color Codes Located and What Do They Mean?
Color codes are printed on one end of the bundle and include the following information:
- Color Name
- Color Code
- Date Code
- Time
- Packaging Line
Examples:
- CHARCOAL DA180B 07-25-2020 13:11 B
- BARKWOOD TU070A 11-14-2019 14:19 B
The other end of the bundle will have only the color name and color code.
Examples:
- CHARCOAL MC180A
- WEATHERED WOOD FO900B
- WEATHERED WOOD MC900H
Understanding Color Codes
Color codes include a plant code, color code, and version letter. Only bundles with the same color code (plant, color code, and version) are considered mixable. Shingles with different color codes should not be mixed, as this will likely result in shading issues.
Preventing Temporary Asphaltic Oil Staining
Temporary asphaltic oil staining can occur during storage. To reduce the possibility of oil staining, it is best practice to install bundles with date codes as close together as possible. For more information, refer to Technical Advisory Bulletin TAB-R-166 on asphaltic oil staining.
Need More Information on Shading?
For further details on visual issues with shingled roofs, refer to Technical Advisory Bulletin TAB-R-137, “Visual Issues with Shingled Roofs.”
Warranty Considerations
Mixing different color codes does not void the GAF Limited Warranty for the shingles. However, any visual inconsistency or shading issues are excluded from GAF’s responsibility under the terms of the Limited Warranty.
Conclusion
Understanding and adhering to shingle color codes is essential for achieving a consistent and visually appealing roof. By ensuring all bundles used for a job have the same color code, you can avoid shading issues and maintain the aesthetic integrity of the roof.
