Don’t Let Blisters Pop Your Commercial Roof Investment: Understanding Membrane Blistering in Palm Beach County’s Unforgiving Heat

In Palm Beach County’s challenging climate, commercial roof membrane blistering has become an increasingly prevalent issue that can compromise your building’s structural integrity and operational efficiency. With Florida’s scorching heat, high humidity, and hurricane-force winds creating unique challenges for commercial roofs, understanding the causes, prevention strategies, and repair solutions for membrane blistering is essential for property owners and facility managers.

Understanding Commercial Roof Membrane Blistering

Roof blisters appear as small bubble-like protrusions, thin and long raised lumps, or large, spongy areas on flat roofs. While small blisters are generally harmless, ones of significant size must be addressed to prevent further damage to your roofing system. A roof blister is a raised area where there is a loss of adhesion of the roof. This area can fill up with air or water to form a blister – which looks like a bubble on your roof.

Roof blisters can occur on any type of conventional, low-slope, and flat roofing system, but they’re most common in membrane systems and built-up roofs (BUR). Membrane systems are most susceptible to blistering because blisters are formed by voids between the plies or at the point between the substrate and the membrane.

Primary Causes of Membrane Blistering in Palm Beach County

Palm Beach County’s extreme climate creates perfect conditions for membrane blistering. During summer months, ponding water trapped between the roof deck and membrane can reach temperatures exceeding 150°F, rapidly converting to vapor that pushes upward to create bubbles and blisters in the roofing material.

The main culprits behind commercial roof membrane blistering include:

• Trapped Moisture: Moisture and air can become trapped in voids between roofing plies or between the substrate and the membrane. As temperatures rise, the heat causes the water vapor to expand, which in turn causes roof blisters.
• Poor Installation: Poor installation is one of the most common causes of roof blistering. It often results from inadequate or rushed workmanship during the roof installation process, leading to trapped air or moisture within the roofing layers.
• Manufacturing Defects: Errors in the manufacturing process of roofing materials can create voids that result in blisters.
• Thermal Cycling: The constant cycle of expansion and contraction weakens the bond between roofing layers, allowing more moisture to get through and form the ideal conditions for blister formation.

Palm Beach County’s Unique Environmental Challenges

Harsh weather events like thunderstorms and hurricanes can cause significant damage to roofs, while the hot and humid climate can lead to moss, algae, and mold growth. The unforgiving sun in West Palm Beach furthers the wear and tear on roofing materials.

South Florida’s weather challenges include high humidity, intense sun, and hurricane season preparedness requirements in Broward and Palm Beach County. These conditions make commercial properties particularly vulnerable to membrane blistering, as the combination of moisture infiltration and extreme heat creates the perfect storm for blister formation.

Prevention Strategies for Commercial Property Owners

Preventing membrane blistering starts with proper installation and ongoing maintenance. The formation of blisters in all conventional low-slope membrane systems can be avoided with proper adhesion of the membrane to the substrate. One hundred percent adhesion is required during application.

Key prevention measures include:

• Professional Installation: Hiring an experienced roofing contractor is one of the most effective ways to prevent blistering. A well-installed roof will have properly applied adhesives, moisture-free materials, and a strong bond to the substrate.
• Quality Materials: The number one rule for preventing commercial roof blisters is to use dry materials in dry settings.
• Regular Inspections: According to GAF, a commercial roof should be inspected at least once a year. Annual inspections can help alert you to blisters and other roofing issues before they turn into major problems that require extensive repair.
• Proper Drainage: Regularly clear away debris, such as leaves and twigs, from your roof to prevent them from clogging drains and gutters and causing water to pool on your roof.

Professional Repair Solutions

When blisters do occur, prompt professional attention is crucial. If the blister is punctured, it could expose the underlying surface to the elements. This could result in water getting inside the roofing system and even into your property’s interior, causing mold growth and water damage.

Professional repair approaches include:

• Minor Blister Repair: For minor blisters that have not ruptured, applying a high-quality adhesive or sealant can help re-bond the membrane to the substrate. This is a cost-effective solution that prevents further separation.
• Membrane Replacement: Cut away the membrane that has lost adhesion, replace any wet insulation with like material, and replace the membrane with overlapping edges at least 6 inches wide.
• Complete Assessment: If water infiltration is suspected, open the membrane and inspect the insulation and deck for damage. Remove wet or damaged insulation and repair or replace the deck as required.

When to Call the Professionals

Often, the sooner you fix roof blisters, the better, as fixing smaller blisters is less labor-intensive and more cost-effective than repairing larger ones or redoing the entire roof. It’s crucial not to try to repair roof blisters yourself. Improper repair attempts can lead to further damage. Roofing professionals have the necessary knowledge, skills, and tools to perform a detailed roof inspection and address blistering properly and safely.
