What does Color Variation mean in shingles?

• A. Slight differences in shingle appearance which may be due to variations in normal manufacturing color blends or the mixing of color blends during shingle application.
• B. Differences in shading that result from weathering.
• C. A rare defect causing uniform color across shingles.
• D. Color variation refers to color of underlying roof felt.

Answer: (A)

Color variation refers to the small differences in how individual shingles look in color. This happens because shingles are manufactured in color blends, and bundles from different lots or different blends are mixed during installation. When you lay shingles from multiple bundles, you’ll often see slight shifts in shade from one piece to the next. This is normal and expected, not a defect. To keep the roof looking even, installers often pull shingles from the same lot or plan the layout to blend colors gradually.

Weathering will change shading over time, but that is a separate process from the initial color variation caused by blends and mixing during installation.
