Asphalt Shingle Blisters: Causes and Solutions

In New Bedford, MA, homeowners enjoy distinct seasons, each bringing its own beauty and challenges to roofing materials, especially asphalt shingles. Understanding the intricacies of asphalt shingle blisters—what causes them and how to effectively address them—is crucial for maintaining the integrity and longevity of your roof. Let’s explore the causes behind these blisters and the solutions that LePage and Sons Roofing LLC can provide.

Understanding Asphalt Shingle Blisters

Asphalt shingle blisters are small, bubble-like raised areas that appear on the surface of roofing shingles. They occur when gases trapped within the shingle expand, causing the outer layer to lift and form a blister. While they may not immediately affect the shingle’s performance, if left unaddressed, these blisters can pop and expose the underlying layers to the elements, potentially leading to leaks and premature roof failure.

Causes of Shingle Blisters

Several factors can contribute to the formation of shingle blisters, including:

• Manufacturing Defects: Occasionally, shingles might have small defects from the manufacturing process that trap moisture or air, which later expands and leads to blisters.

• Poor Ventilation: Inadequate attic ventilation can cause heat to build up underneath the shingles, accelerating the blistering process.

• Direct Sunlight Exposure: Prolonged exposure to the sun’s UV rays can exacerbate the blistering, especially in areas like New Bedford, where the summer sun can be particularly intense.

• Moisture: Moisture trapped within the shingle during manufacturing or from roof leaks can also cause blistering as it heats and expands.

Solutions to Address and Prevent Asphalt Shingle Blisters

Proper Installation Techniques

Ensuring that asphalt shingles are installed correctly is the first step toward preventing blisters. This includes using the right nail technique and ensuring that the attic has proper ventilation to reduce heat buildup.

Regular Roof Inspections

LePage and Sons Roofing LLC strongly emphasizes the importance of regular roof inspections. Routine checks can identify early signs of blistering and other issues, allowing for timely repairs before significant damage occurs.

Immediate Repairs

If shingle blisters are detected, it’s crucial to address them promptly. While not all blisters pose an immediate threat to the roof’s integrity, they should be evaluated by a professional roofing contractor to determine the best course of action.

Improving Roof Ventilation

Enhancing the attic’s ventilation can significantly reduce the risk of blister formation. Proper ventilation helps to regulate the temperature underneath the shingles, preventing the excessive heat that can lead to blistering.

Choosing Quality Shingle Products

Investing in high-quality asphalt shingles from reputable manufacturers can decrease the likelihood of blistering due to manufacturing defects. These products often come with warranties that cover such issues, offering an additional layer of protection for homeowners.
