Introduction

Asphalt shingles are a popular roofing material, known for their durability and cost-effectiveness. However, they can be prone to a phenomenon known as blistering. This post explores what causes blistering and how to address it.

Understanding Asphalt Shingle Blistering

What Causes Blistering?

Blistering in asphalt shingles can occur due to several factors, including trapped moisture during manufacturing, poor attic ventilation, or excessive heat. The moisture inside the shingle expands when heated, creating blisters.

Effects of Blistering on Roofing

While blistering may not immediately affect the roof's performance, over time, these blisters can pop and lead to granule loss, reducing the shingle's effectiveness in protecting against UV rays and weather elements.

Preventing Blistering in Asphalt Shingles

Proper Ventilation

Good attic ventilation is crucial in preventing excessive heat buildup, which can lead to blistering.

Quality Installation

Ensuring shingles are properly installed by a professional can reduce the risk of blistering.

Regular Maintenance

Regular roof inspections and maintenance can help identify and mitigate early signs of blistering.

Repairing Blistered Asphalt Shingles

When to Repair

If blisters are compromising the integrity of the shingles, it's time to consider repairs or replacement.

Choosing the Right Contractor

Select a reputable contractor experienced in dealing with blistered shingles for any repairs or replacements.

Conclusion

Understanding and addressing the causes of blistering in asphalt shingles can significantly extend the life of your roof. Regular inspections, proper maintenance, and professional repairs are key to managing this common issue.
