What Causes Discoloration in Asphalt Shingles?

As the premier roofing experts in Centennial, CO, Jack the Roofer has often encountered homeowners concerned about the discoloration of their asphalt shingles. While asphalt shingles are popular due to their durability and aesthetic appeal, discoloration can detract from your home’s overall look and may indicate underlying issues. Understanding what causes this discoloration and how to prevent it is essential for maintaining your roof’s integrity and appearance.

Algae Growth

One of the most common causes of discoloration on asphalt shingles is the growth of algae. This is particularly prevalent in areas with high humidity or proximity to water bodies. Algae growth can cause unsightly black or green streaks on your shingles. To combat this issue, consider installing algae-resistant shingles or apply anti-algae treatments. Regular roof cleaning by professionals can also prevent algae buildup.

Moss Buildup

Moss thrives in cool, moist environments and can often be found on roofs that are shaded and exposed to frequent moisture. Unlike algae, moss can be more than just a cosmetic issue; it can lift and separate shingles, compromising the roof’s protective qualities. Removing trees or trimming branches that overhang the roof can reduce shade and moisture, making the environment less hospitable to moss. Installation of zinc or copper strips at the ridge of the roof can also help in moss prevention, as these metals are natural moss inhibitors.

Water Damage and Poor Ventilation

Prolonged exposure to water and poor ventilation can cause shingles to discolor and deteriorate. Ensuring proper attic ventilation and gutter maintenance can prevent water accumulation and promote air circulation, mitigating the risk of water damage. It’s crucial to conduct regular roof inspections to identify and rectify potential ventilation issues or water damage early.

UV Exposure

The intense sun and UV radiation in Colorado can fade and discolor asphalt shingles over time. Although UV exposure is unavoidable, selecting shingles with UV-resistant granules can slow down the process of discoloration and wear. Regular inspections can help identify areas of concern early, allowing for timely interventions to preserve your roof’s color and condition.

Manufacturing Defects

While less common, manufacturing defects can also lead to premature discoloration of asphalt shingles. Opting for shingles from reputable manufacturers and ensuring proper installation can mitigate this risk. Jack the Roofer works with high-quality materials and employs experienced technicians to ensure that your roof is free from such defects.
