5 Things to know about roof blistering.
For this month’s blog post we wanted to bring some attention to one roof condition that most homeowners don’t know about or have not heard of. We are talking about Roof Blistering.
This issue comes up usually in very humid and hot states and since we are located in Texas we see this issue once in a while, so wanted to share 5 things to know about roof blistering, so you can be aware and prepared.
What Are Roof Blisters?:
Roof blisters are raised, bubble-like formations on the surface of a roofing material, typically asphalt shingles or built-up roofing membranes. They are caused by the expansion of air or moisture trapped between the layers of the roof, creating a visible and sometimes palpable bulge.
Causes of Roof Blisters:
Moisture Trapped During Installation: One of the most common causes of roof blisters is moisture that becomes trapped between the layers of roofing material during installation. This moisture can result from rain, dew, or improper storage of roofing materials.
High Temperatures: Elevated temperatures can cause trapped moisture or air to expand, creating blisters.
Poor Ventilation: Inadequate attic or roof ventilation can lead to excessive heat buildup, exacerbating the risk of blisters by heating the roofing materials from underneath.
Impact on Roof Longevity:
Roof blisters can reduce the overall lifespan of your roofing material if left unaddressed. Over time, blisters may rupture, exposing the underlying layers of the roof to the elements, which can lead to water infiltration and damage to the roof's structure.
Detection and Inspection:
Regular roof inspections are essential for detecting blisters. You may be able to spot them from ground level, but a professional roofing contractor should perform a thorough inspection, including a close-up examination of the roof's surface. Infrared thermography can also be used to identify areas with trapped moisture.
Repair and Prevention:
If you discover roof blisters, it's essential to address them promptly. Repair typically involves cutting open the blister, removing the trapped air or moisture, and then sealing the area with roofing cement or adhesive. Preventative measures include ensuring proper ventilation in your attic or roof space and using roofing materials and installation practices that minimize the risk of blister formation.
Remember that roof blisters can vary in severity, and while some may be minor cosmetic issues, others can lead to more significant problems if not addressed. If you think your roof might have this issue. We are ready to provide you with a thorough inspection for an accurate assessment and appropriate repair or prevention solutions tailored to your specific roofing system.
