The icicles hanging on the front of my house are yellow on the tips. I also noticed a yellow line in the snow beneath the icicles. We moved into this home recently and I know they had the roof replaced due to hail damage. Any idea what would cause the yellow? Is this glue from the overhanging shingles?

  • Pollen on the roof before the snow?

Most likely the water is absorbing stain from the new shingles.

This will change over time as the new shingles weather.
