What Is Shingle Cupping And How Do You Prevent It?


Shingle cupping is a common roofing problem that can affect the appearance and performance of your roof. In this blog post, we will explore what shingle cupping is, its causes, and effective prevention methods. Understanding this issue will help you maintain the integrity and longevity of your roof through shingle cupping prevention.

Causes of Shingle Cupping:

Shingle cupping occurs when the edges of asphalt shingles curl or become raised, creating a concave shape. This can be caused by various factors, including:

  1. Moisture Imbalance: Uneven moisture exposure can cause the shingles to expand and contract unevenly, leading to cupping.
  2. Improper Ventilation: Inadequate attic ventilation can trap excess heat and moisture, affecting the shingles’ performance and contributing to cupping.
  3. Aging and Weathering: Over time, shingles can naturally deteriorate and become more susceptible to cupping due to exposure to harsh weather conditions.

Preventing Shingle Cupping:

Prevention is key when it comes to shingle cupping. Here are some effective measures you can take to prevent this issue:

  1. Proper Ventilation: Ensure your roof has adequate ventilation to promote air circulation and prevent moisture buildup. This can be achieved through the installation of ridge vents, soffit vents, and attic fans.
  2. Regular Inspections: Schedule regular roof inspections to detect any signs of cupping or other roofing issues early on. Prompt repairs or replacement of damaged shingles can help prevent further cupping.
  3. Professional Installation: Hire a reputable roofing contractor with experience in proper shingle installation techniques. Correct installation methods, such as using the right amount of nails and ensuring proper overlap, can minimize the risk of cupping.
  4. Addressing Moisture Issues: Take steps to address any moisture issues in your attic or roof space. This may include improving insulation, sealing gaps, and addressing plumbing or HVAC leaks promptly.
  5. Regular Maintenance: Maintain your roof by removing debris, keeping gutters clean, and addressing any issues promptly. Regular maintenance can help prevent cupping and prolong the lifespan of your shingles.
