Color code numbers on shingles are used to identify the color on each bundle and must match. Which statement best describes their purpose?

• A. They identify the color on each bundle of shingles and must match.
• B. They indicate the warranty period.
• C. They indicate granule size.
• D. They indicate the year of manufacture.

Answer: (B)

The main idea is that color code numbers on shingles are there to identify the color on each bundle so you can keep colors consistent across the roof. By matching the codes, you’re ensuring that all bundles being used together are the same shade, which helps achieve a uniform look and makes it easy to replace a damaged bundle with a matching one later. These codes are not about how long the warranty lasts, nor do they indicate granule size or the year of manufacture; those details come from other labels or documentation.
