What To Do About Roof Blisters

Roof blisters are phenomena that occur when pockets of air or moisture become trapped between layers of roofing materials. Over time, with the exposure to the elements such as sunlight and heat, these pockets can expand and cause the layers above to rise and form bubble-like protrusions. These blisters are not only an aesthetic concern but can also signify underlying issues with the roofing system.

Understanding the formation of roof blisters is crucial for addressing them effectively. Typically, they arise during the installation process when the roofing material is not properly adhered, or if there is moisture present that later gets encapsulated. In other cases, poor ventilation can lead to trapped heat, which causes the roofing material to expand and form blisters. The roof’s age and the quality of the materials used also play a role in blister formation.

Roof blisters can affect various types of roofs but are most commonly seen in built-up roofing and modified bitumen systems. If left unattended, these blisters can lead to premature aging of the roof, leaks, and in some cases, significant structural damage. It is vital for property owners to recognize and address roof blister issues before they escalate into more severe roof problems. For a faster and better roof replacement, you need to contact specialists as soon as possible to replace the old roof with a new one and prevent leakage damage in the interior.

Understanding Roof Blisters

Roof blisters are defects that occur when trapped moisture or air expands, affecting the integrity of the roofing material. Recognizing and addressing these blisters are critical to maintaining a roof’s condition.

Formation and Causes

Roof blisters form when pockets of air or moisture become trapped between layers of roofing materials or within the roofing substrate itself. They are commonly caused by:

• Poor installation: Inadequate bonding between layers of roofing material allows air or moisture to seep in.
• Thermal expansion: Fluctuations in temperature cause roofing materials to expand and contract, which can trap air or moisture.
• Aging materials: Over time, roofing materials can deteriorate, creating pathways for air and moisture.

Trapped gasses or moisture expand with heat, eventually forming raised areas known as blisters on the roof.

Significance and Consequences

The impact of roof blisters on the overall health of your roof includes:

• Reduced lifespan: The integrity of the roofing system is compromised, potentially reducing the expected lifespan.
• Potential leaks: Blisters can lead to cracks or ruptures, allowing water to enter the building.
• Aesthetic damage: The appearance of the roof can be negatively affected by the presence of blisters.

It is important to identify common causes and signs of roof blisters early to prevent these consequences and preserve the roof’s functionality.

Identification and Prevention

Managing roof blisters effectively requires both accurate identification and proactive prevention measures. It’s critical to promptly catch these defects and address underlying issues to prolong the lifespan of a roof.

Recognizing Roof Blisters

Roof blisters are raised areas that occur when pockets of air or moisture get trapped within the roofing materials, typically found in asphalt roofs. They can vary in size and can be located by inspecting the roof surface for areas that appear swollen or have a bubble-like structure. Key indicators include:

• Visual inspection: Look for roundish, raised areas on the roof surface.
• Physical touch: Gently pressing on suspected areas can help determine if blistering has occurred, as blisters tend to have a spongy feel.

Expert tip: Regular inspection by professionals can help catch blisters before they worsen.

Strategies for Prevention

Preventing roof blisters begins with understanding their common causes, such as poor ventilation, trapped moisture, or installation errors. To avoid future blistering:

• Proper installation: Ensure that roofing materials are installed correctly and without moisture. It is crucial to follow manufacturer guidelines.
• Adequate ventilation: Good attic and roof ventilation help to remove excess heat and moisture that can contribute to blistering.
• Regular maintenance: Schedule frequent professional inspections and maintenance to catch and replace issues early.
• Quality materials: Investing in high-quality roofing materials can reduce the likelihood of blister formation.

Expert recommendations suggest that implementing these strategies can significantly decrease the incidence of roof blistering.

Replacement Solutions

When addressing roof blisters, homeowners have two primary paths to consider: undertaking the replacing themselves or seeking out professional help. Each approach has its protocols and precautions.

DIY Repalcment Tips

For individuals comfortable with hands-on work, replacing roof blisters themselves can be a cost-effective option. The following are steps to perform a basic:

1. Safety First: Ensure you have the appropriate safety gear such as gloves, non-slip boots, and eye protection.
2. Equipment: You will need a utility knife, roofing cement, a putty knife, and a caulking gun.
3. Inspection: Carefully inspect the blistered area for signs of moisture. If water has infiltrated, extra measures to dry the area will be necessary.
4. Cutting the Blister: Carefully slice through the blister with the utility knife without damaging the underlying layers.
5. Gluing Down: Dry the exposed area. Then, apply a generous amount of roofing cement under the edges, and press down firmly.
6. Sealing: Apply more roofing cement on top of the cut, ensuring it spreads beyond the edges of the blister. Embed a piece of fiberglass mesh in the cement, and then cover with another layer of cement.

Remember, safety is crucial when working at heights. If the roof has a steep slope or if the blistering is extensive, professional services might be the safer choice.
