Asphalt roofing has long been celebrated for its durability and reliability. It’s a top choice for many homeowners, and for good reason. However, like all materials, asphalt shingles can sometimes exhibit issues. One such concern is the appearance of blisters on the shingles. At Exterior Pro, we believe in keeping our clients informed. Let’s dive deep into the world of asphalt shingle blisters, understanding their causes, implications, and prevention methods.
Unraveling the Mystery of Shingle Blisters
While shingle blisters might seem alarming at first glance, they’re often benign and primarily a cosmetic concern. However, it’s essential to monitor these blisters, especially during routine roof inspections. If left unchecked, popped blisters can lead to significant roof damage.
Delving into the Causes
Several factors can lead to the formation of blisters on asphalt shingles:
Moisture Trapped in Shingle Layers: During the manufacturing process, moisture can sometimes get trapped within the shingle layers. When these shingles are installed and subsequently exposed to sunlight, the trapped moisture can rise, leading to visible blisters on the surface.
Inadequate Attic Ventilation: Proper attic ventilation is crucial for the health of your roof. Without it, warm air can accumulate, causing the shingles to overheat. This heat can exacerbate the trapped moisture issue, resulting in blisters.
Installation Errors: Blisters can also arise due to installation errors. For instance, if shingles are installed at inappropriate temperatures, it can lead to wrinkles and potential leaks, eventually causing blisters.
Should You Be Concerned?
Asphalt shingles are designed to withstand the elements. With proper installation and regular maintenance, they can effectively combat heavy rains, hailstorms, and other weather challenges. While blisters might not impact the performance or longevity of your roof, they can mar its appearance. It’s essential to monitor these blisters and consult roofing experts if you notice any significant granule loss.
Distinguishing Between Blisters and Hail Damage
It’s easy to confuse blisters with hail damage, given their visual similarities. However, a trained eye can discern the difference:
Pattern: If you observe a mix of popped and unpopped blisters, it’s likely blistering. Uniformly popped blisters, on the other hand, indicate hail damage.
Location: Blisters can appear randomly across the roof, while hail damage often concentrates in specific areas.
Dents: Hailstones can create dents on the roof, a damage type not associated with blistering.
Proactive Measures to Prevent Blisters
At Exterior Pro, we believe prevention is better than cure. Here are some proactive steps to safeguard your roof against blisters:
Prioritize Proper Installation: Partnering with a reputable roofing contractor ensures your shingles are installed correctly, minimizing the risk of blisters.
Maintain Nearby Trees: Overhanging branches and falling debris can damage your shingles, potentially causing blisters. Regularly trim trees near your roof to prevent such issues.
Regular Gutter Maintenance: Clean gutters prevent water accumulation, reducing the risk of moisture-related problems. Regularly inspect your gutters for shingle granules, as this could indicate popped blisters.
Routine Roof Inspections: Regular inspections can identify potential issues before they escalate. If your roof has blisters, ensure your roofing professional exercises caution during inspections to avoid popping them.
