Understanding Asphalt Shingle Blistering

Asphalt shingle blistering is a common issue faced by homeowners, often leading to confusion and concern about the integrity of their roofing. At KVN Construction, we believe in empowering our clients with in-depth knowledge to address this problem effectively.

The Phenomenon of Shingle Blistering

Shingle blistering occurs when small, bubble-like protrusions form on the surface of asphalt shingles. This phenomenon can be attributed to various factors, including manufacturing defects, improper roof ventilation, and excessive heat.

Manufacturing Defects

During the production of asphalt shingles, any inconsistencies in the mat saturation process or granule adhesion can lead to blistering. These defects might not be visible immediately but can surface over time as the shingles are exposed to environmental elements.

Improper Roof Ventilation

Adequate ventilation is crucial for maintaining the longevity of a roof. Poor ventilation leads to heat buildup in the attic, causing the shingles to overheat. This excessive heat can cause the volatile compounds in the asphalt to expand, resulting in blistering.

Excessive Heat and Sun Exposure

Asphalt shingles are designed to withstand sunlight and heat. However, prolonged exposure to extreme conditions can accelerate the aging process, making the shingles more susceptible to blistering.

Preventive Measures and Solutions

Regular Roof Inspections

Routine inspections by professional roofing contractors in Portland OR are essential. These inspections can identify early signs of blistering, allowing for timely interventions.

Enhancing Roof Ventilation

Improving attic ventilation is a key step in preventing shingle blistering. Proper air circulation helps in regulating the temperature and reduces the risk of heat buildup.

Choosing Quality Shingles

Investing in high-quality shingles from reputable roofing companies in Portland OR can significantly reduce the likelihood of blistering. These shingles are designed to offer better resistance to environmental factors.
