Asphalt Shingle Blisters: Causes and Solutions

In Middletown, NY, homeowners are all too familiar with the challenges posed by the local climate to their roofing systems. Among these, asphalt shingle blisters stand out as a common yet often misunderstood issue. These blisters can compromise the aesthetic and functional integrity of a roof. Understanding the causes of blister formation and implementing timely solutions is crucial. Proper installation and regular inspections are essential in preventing and managing this issue.

Understanding Asphalt Shingle Blisters

Asphalt shingle blisters are raised areas that appear on the surface of the shingle, where a void or bubble has formed. These can range in size and severity, and while they might not immediately indicate a failure in the roofing material, they can lead to more significant issues if not addressed. Blistering often results from moisture trapped within the shingle during manufacture or from excessive heat.

Causes of Shingle Blisters

Several factors contribute to the formation of blisters on asphalt shingles. One of the primary causes is improper roof ventilation. Inadequate ventilation leads to excessive heat buildup in the attic, which can then cause the shingles to overheat and blister. Another cause is moisture entrapment during the manufacturing process, where moisture trapped within the shingle expands when heated by the sun.

Furthermore, poor installation techniques can exacerbate or directly cause blistering. This includes the use of low-quality roofing materials or incorrect nailing techniques, where nails are driven too tightly, creating tension in the shingle that can lead to blistering.

Preventative Measures

To combat the formation of asphalt shingle blisters, several preventative measures can be taken. Firstly, ensuring proper roof ventilation is crucial. Adequate attic ventilation helps to regulate temperatures and prevents the buildup of excessive heat under the roofing material.

Choosing high-quality roofing materials and a reputable contractor for installation is also vital. High-quality materials are less likely to contain manufacturing defects, including moisture entrapment. Furthermore, professional installers understand the importance of proper nailing and ventilation techniques, which can significantly reduce the risk of blistering.

Regular Inspections and Maintenance

Regular inspections and maintenance are key to identifying and addressing blisters before they develop into more significant issues. Home Pro Exteriors, Inc. recommends having your roof inspected at least once a year or after severe weather events. During these inspections, professionals can identify early signs of blistering and recommend appropriate actions, whether it be repair or preventive maintenance.

In some cases, minor blistering does not require immediate intervention, but monitoring the condition to ensure it doesn’t worsen is essential. Timely repairs can extend the life of your roof and prevent the need for premature replacement.

Solutions for Existing Blisters

When blisters are identified on an asphalt shingle roof, solutions range from monitoring the condition to replacing affected shingles or, in severe cases, the entire roof. The appropriate action depends on the extent of the damage and the roof’s overall condition. Home Pro Exteriors, Inc. provides expert assessments to determine the best course of action for homes in Middletown, NY and the surrounding areas.

It’s important to address any concerns with your roofing system promptly to maintain its integrity and protect your home from potential damages.
